study was to investigate the relationship between sprint and vertical jump performance in elite female football players. Twenty four professional female football players (age, 18.6±3.1 years; height, 168.3±6.3 cm, body mass 61.6±7.4 kg; mean±SD) were tested for 30-m sprint time, 10-m sprint time and vertical countermovement (CMJ) and squat (SJ) jumps height. Participants performed three countermovement jumps and three squat jumps for maximal height on a force platform. Mean values of three trials were used in statistical analysis. The displacement of center of mass (COM) during flight phase (e.g. jump height) was calculated using the vertical velocity of the COM at the moment of take-off. 30-m and 10-m sprint time were measured using OptoGait optical system. The best of three trials were used for analysis. A significant negative correlation was found between 30-m sprint time and CMJ, SJ height (r = -0.85, r = -0.79 respectively), between 10-m sprint time and CMJ, SJ height (r = -0.73, r = -0.8 respectively), and step frequency was significantly related to CMJ peak power (r = -0.57). Our study indicates that there is strong correlation between sprint and jump performance in elite female football players, thus vertical jump test can be considered as a good sprint and agility predictor in female football. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agility" title="agility">agility</a>, <a href="https://publications.waset.org/abstracts/search?q=female%20football%20players" title=" female football players"> female football players</a>, <a href="https://publications.waset.org/abstracts/search?q=sprint%20performance" title=" sprint performance"> sprint performance</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20jump%20height" title=" vertical jump height"> vertical jump height</a> </p> <a href="https://publications.waset.org/abstracts/59039/correlation-between-sprint-performance-and-vertical-jump-height-in-elite-female-football-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59039.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">469</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2633</span> Relationship between Dynamic Balance and Explosive Leg Power in Young Female Gymnasts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Aleksic-Veljkovic">A.

A single-group design was used. Forty-seven young, female gymnasts (Mean±SD; age: 8-12 years, height: 42.88±10.38 cm, mass: 35.59±8.15 kg; body mass index: 17.18±1.62 kg/m2; training hours per week: 15-18 h/week) performed measurements of dynamic balance and countermovement jump with and without arm swing. Significant, but small to medium associations were observed between variables of balance and height of the jump in both protocols of the countermovement jump ranging from r = +0.313 to +0.426. No significant associations were observed between variables of dynamic balance and relative power and peak power of countermovement jump with or without arm swings. The data indicate that dynamic balance and leg power imply that balance and power are independent of each other and may have to be tested and trained complementarily in young gymnasts. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artistic%20gymnastics" title="artistic gymnastics">artistic gymnastics</a>, <a href="https://publications.waset.org/abstracts/search?q=countermovement%20jump" title=" countermovement jump"> countermovement jump</a>, <a href="https://publications.waset.org/abstracts/search?q=jump%20height" title=" jump height"> jump height</a>, <a href="https://publications.waset.org/abstracts/search?q=testing" title=" testing"> testing</a> </p> <a href="https://publications.waset.org/abstracts/41548/relationship-between-dynamic-balance-and-explosive-leg-power-in-young-female-gymnasts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41548.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">394</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2632</span> Effect of High-Intensity Core Muscle Exercises Training on Sport Performance in Dancers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Che%20Hsiu%20Chen">Che Hsiu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Yun%20Chen"> Su Yun Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hon%20Wen%20Cheng"> Hon Wen Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Traditional core stability, core endurance, and balance exercises on a stable surface with isometric muscle actions, low loads, and multiple repetitions, which may not improvements the swimming and running economy performance. However, the effects of high intensity core muscle exercise training on jump height, sprint, and aerobic fitness remain unclear. The purpose of this study was to examine whether high intensity core muscle exercises training could improve sport performances in dancers. Thirty healthy university dancer students (28 women and 2 men; age 20.0 years, height 159.4 cm, body mass 52.7 kg) were voluntarily participated in this study, and each participant underwent five suspension exercises (e.g., hip abduction in plank alternative, hamstring curl, 45-degree row, lunge and oblique crunch). Each type of exercise was performed for 30-second, with 30-second of rest between exercises, two times per week for eight weeks and each exercise session was increased by 10-second every week. We measured agility, explosive force, anaerobic and cardiovascular fitness in dancer performance before and after eight weeks of training. The results showed that the 8-week high intensity core muscle training would significantly increase T-test agility (7.78%), explosive force of acceleration (3.35%), vertical jump height (8.10%), jump power (6.95%), lower extremity anaerobic ability (7.10%) and oxygen uptake efficiency slope (4.15%). Therefore, it can be concluded that eight weeks of high intensity core muscle exercises training can improve not only agility, sprint ability, vertical jump ability, anaerobic and but also cardiovascular fitness measures as well. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=jump%20height" title=" jump height"> jump height</a>, <a href="https://publications.waset.org/abstracts/search?q=sprint" title=" sprint"> sprint</a>, <a href="https://publications.waset.org/abstracts/search?q=maximal%20oxygen%20uptake" title=" maximal oxygen uptake"> maximal oxygen uptake</a> </p> <a href="https://publications.waset.org/abstracts/50790/effect-of-high-intensity-core-muscle-exercises-training-on-sport-performance-in-dancers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">407</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2631</span> Maximum Power and Bone Variables in Young Adult Men</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anthony%20Khawaja">Anthony Khawaja</a>, <a href="https://publications.waset.org/abstracts/search?q=Jacques%20Prioux"> Jacques Prioux</a>, <a href="https://publications.waset.org/abstracts/search?q=Ghassan%20Maalouf"> Ghassan Maalouf</a>, <a href="https://publications.waset.org/abstracts/search?q=Rawad%20El%20Hage"> Rawad El Hage</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The regular practice of physical activities characterized by significant mechanical stresses stimulates bone formation and improves bone mineral density (BMD) in the most solicited sites. The purpose of this study was to explore the relationships between maximum power and bone variables in a group of young adult men. Identification of new determinants of BMD, bone mineral content (BMC) and hip geometric indices in young adult men, would allow screening and early management of future cases of osteopenia and osteoporosis. Fifty-three young adult men (18 – 35yr) voluntarily participated in this study. Weight and height were measured, and body mass index was calculated. Body composition, BMC and BMD were determined for each individual by Dual-energy X-ray absorptiometry (DXA; GE Healthcare, Madison, WI) at whole body (WB), lumbar spine (L1-L4), total hip (TH), and femoral neck (FN). FN cross-sectional area (CSA), strength index (SI), buckling ratio (BR), FN section modulus (Z), cross-sectional moment of inertia (CSMI) and L1-L4 TBS were also evaluated by DXA. The vertical jump was evaluated using a field test (sargent test). Two main parameters were retained: vertical jump performance (cm) and power (w). The subjects performed three jumps with 2 minutes of recovery between jumps. The highest vertical jump was selected. Maximum power (P max, in watts) was calculated. Maximum power was positively correlated to WB BMD (r = 0.41; p < 0.01), WB BMC (r = 0.65; p < 0.001), L1-L4 BMC (r = 0.54; p < 0.001), FN BMC (r = 0.35; p < 0.01), TH BMC (r = 0.50; p < 0.001), CSMI (r = 0.50; p < 0.001), CSA (r = 0.33; p < 0.05). Vertical jump was positively correlated to WB BMC (r = 0.31; p < 0.05), L1-L4 BMC (r = 0.40; p < 0.01), CSMI (r = 0.29; p < 0.05). The current study suggests that maximum power is a positive determinant of BMD, BMC and hip geometric indices in young adult men. In addition, it shows also that maximum power is a stronger positive determinant of bone variables than vertical jump in this population. Implementing strategies to increase maximum power in young adult men may be useful for preventing osteoporotic fractures later in life. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bone%20variables" title="bone variables">bone variables</a>, <a href="https://publications.waset.org/abstracts/search?q=maximum%20power" title=" maximum power"> maximum power</a>, <a href="https://publications.waset.org/abstracts/search?q=osteopenia" title=" osteopenia"> osteopenia</a>, <a href="https://publications.waset.org/abstracts/search?q=osteoporosis" title=" osteoporosis"> osteoporosis</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20jump" title=" vertical jump"> vertical jump</a>, <a href="https://publications.waset.org/abstracts/search?q=young%20adult%20men" title=" young adult men"> young adult men</a> </p> <a href="https://publications.waset.org/abstracts/98422/maximum-power-and-bone-variables-in-young-adult-men" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98422.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">178</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2630</span> Investigating Relationship between Body Size and Physical Fitness Factors among University Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Allahyar%20Arabmomeni">Allahyar Arabmomeni</a>, <a href="https://publications.waset.org/abstracts/search?q=Hojjatollah%20Alaei"> Hojjatollah Alaei </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The objectives of this study was to investigate effect of anthropometric variables and body composition on physical capabilities among male and female students. Materials and Methods: The study had a descriptive correlation method. The statistical population consisted of all students of Islamic Azad University, Khomeinishahr Branch, from 2011 to 2013, which was about 7000 students. The statistical sample included 300 male and 300 female students who were randomly selected from among university students in proportion to frequency of students in each faculty. Descriptive statistical methods, t-test and Pearson correlation coefficient were used for data analysis. Results: Results of this research showed that body size of male students in the studied variables was more than that of female students (p<0.05). Moreover, there was significant difference between all the variables based on significance level of the table. Also, the results taken from the Pearson correlation of this study's variables showed a positive relationship between height and leg and hand length and sit-up, full-ups bar and vertical jump tests (p<0/01). Besides, there was a positive correlation between hand length, sit-up, full-ups bar and vertical jump tests. As far as tests of length of legs and vertical jump were concerned, a highly positive correlation was observed between them. Additionally, results of this study indicated a significant correlation at alpha level of 0.05 between age and height of the students; but, there was a negative correlation between age, sit-up and 1600-m tests (p<0.05). Conclusion: The results of this study indicated a relationship between size of weight, height, length of hands and legs and some physical fitness tests. Therefore, it is required to consider anthropometric factors in addition to gender and age while preparing norms of physical fitness since variables of height and length of hands also affect physical fitness evaluation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropometric%20variables" title="anthropometric variables">anthropometric variables</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20fitness%20factors" title=" physical fitness factors"> physical fitness factors</a>, <a href="https://publications.waset.org/abstracts/search?q=students" title=" students"> students</a>, <a href="https://publications.waset.org/abstracts/search?q=body%20composition" title=" body composition"> body composition</a> </p> <a href="https://publications.waset.org/abstracts/2054/investigating-relationship-between-body-size-and-physical-fitness-factors-among-university-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2054.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">392</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2629</span> Rate of Force Development, Net Impulse and Modified Reactive Strength as Predictors of Volleyball Spike Jump Height among Young Elite Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Javad%20Sarvestan">Javad Sarvestan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zdenek%20Svoboda"> Zdenek Svoboda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Force-time (F-T) curvature characteristics are globally referenced as the main indicators of athletic jump performance. Nevertheless, to the best of authors’ knowledge, no investigation tried to deeply study the relationship between F-T curve variables and real-game jump performance among elite volleyball players. To this end, this study was designated to investigate the association between F-T curve variables, including movement timings, force, velocity, power, rate of force development (RFD), modified reactive strength index (RSImod), and net impulse with spike jump height during real-game circumstances. Twelve young elite volleyball players performed 3 countermovement jump (CMJ) and 3 spike jump in real-game circumstances with 1-minute rest intervals to prevent fatigue. Shapiro-Wilk statistical test illustrated the normality of data distribution, and Pearson’s product correlation test portrayed a significant correlation between CMJ height and peak RFD (0.85), average RFD (r=0.81), RSImod (r=0.88) and concentric net impulse (r=0.98), and also significant correlation between spike jump height and peak RFD (0.73), average RFD (r=0.80), RSImod (r=0.62) and concentric net impulse (r=0.71). Multiple regression analysis also reported that these factors have a strong contribution in predicting of CMJ (98%) and spike jump (77%) heights. Outcomes of this study confirm that the RFD, concentric net impulse, and RSImod values could precisely monitor and track the volleyball attackers’ explosive strength, muscular stretch-shortening cycle function efficiency, and ultimate spike jump height. To this effect, volleyball coaches and trainers are advised to have an in-depth focus on their athletes’ progression or the impacts of strength trainings by observing and chasing the F-T curve variables such as RFD, net impulse, and RSImod. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=net%20impulse" title="net impulse">net impulse</a>, <a href="https://publications.waset.org/abstracts/search?q=reactive%20strength%20index" title=" reactive strength index"> reactive strength index</a>, <a href="https://publications.waset.org/abstracts/search?q=rate%20of%20force%20development" title=" rate of force development"> rate of force development</a>, <a href="https://publications.waset.org/abstracts/search?q=stretch-shortening%20cycle" title=" stretch-shortening cycle"> stretch-shortening cycle</a> </p> <a href="https://publications.waset.org/abstracts/120356/rate-of-force-development-net-impulse-and-modified-reactive-strength-as-predictors-of-volleyball-spike-jump-height-among-young-elite-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120356.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">135</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2628</span> Valuation of Caps and Floors in a LIBOR Market Model with Markov Jump Risks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shih-Kuei%20Lin">Shih-Kuei Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The characterization of the arbitrage-free dynamics of interest rates is developed in this study under the presence of Markov jump risks, when the term structure of the interest rates is modeled through simple forward rates. We consider Markov jump risks by allowing randomness in jump sizes, independence between jump sizes and jump times. The Markov jump diffusion model is used to capture empirical phenomena and to accurately describe interest jump risks in a financial market. We derive the arbitrage-free model of simple forward rates under the spot measure. Moreover, the analytical pricing formulas for a cap and a floor are derived under the forward measure when the jump size follows a lognormal distribution. In our empirical analysis, we find that the LIBOR market model with Markov jump risk better accounts for changes from/to different states and different rates. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arbitrage-free" title="arbitrage-free">arbitrage-free</a>, <a href="https://publications.waset.org/abstracts/search?q=cap%20and%20floor" title=" cap and floor"> cap and floor</a>, <a href="https://publications.waset.org/abstracts/search?q=Markov%20jump%20diffusion%20model" title=" Markov jump diffusion model"> Markov jump diffusion model</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20forward%20rate%20model" title=" simple forward rate model"> simple forward rate model</a>, <a href="https://publications.waset.org/abstracts/search?q=volatility%20smile" title=" volatility smile"> volatility smile</a>, <a href="https://publications.waset.org/abstracts/search?q=EM%20algorithm" title=" EM algorithm"> EM algorithm</a> </p> <a href="https://publications.waset.org/abstracts/11690/valuation-of-caps-and-floors-in-a-libor-market-model-with-markov-jump-risks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/11690.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">421</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2627</span> Immediate Effect of Augmented Feedback on Jumping Performance of the Athletes with Dynamic Knee Valgus</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamadreza%20Hatefi">Mohamadreza Hatefi</a>, <a href="https://publications.waset.org/abstracts/search?q=Malihe%20Hadadnezhad"> Malihe Hadadnezhad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It is well established that jump-landing-related biomechanical deficiencies, such as dynamic knee valgus (DKV), can be improved by using various forms of feedback; However, the effectiveness of these interventions synchronously on athletes' jumping performance remains unknown. Twenty-one recreational athletes with DKV performed countermovement jump (CMJ) and drop vertical jump (DVJ) tasks before and after feedback intervention while the kinematic, force plate and electromyography data of the lower extremity were synchronously captured. The athletes’ jumping performance was calculated by using the reactive strength index-modified (RSIₘₒ𝒹). The athletes at the post-intervention exhibited significantly less hip adduction and more tibial internal rotation during both CMJ and DVJ tasks and maximum knee flexion just during DVJ task. Moreover, athletes exhibited increased time to take-off and consequently decreased RSIₘₒ𝒹 during DVJ task, but no difference was observed in CMJ task. Feedback immediately improved DKV without disturbing the athletes’ jumping height during both tasks, But athletes exhibited increased time to take-off and consequently decreased RSIₘₒ𝒹 only during DVJ task, which suggests that the results may differ according to the nature of jumping task. Nevertheless, the effectiveness of landing-related biomechanical deficiencies improvement on athletes' jumping performance must be investigated in the long-term as a new movement pattern. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=reactive%20strength%20index" title="reactive strength index">reactive strength index</a>, <a href="https://publications.waset.org/abstracts/search?q=feedback" title=" feedback"> feedback</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20knee%20valgus" title=" dynamic knee valgus"> dynamic knee valgus</a> </p> <a href="https://publications.waset.org/abstracts/166613/immediate-effect-of-augmented-feedback-on-jumping-performance-of-the-athletes-with-dynamic-knee-valgus" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/166613.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2626</span> Analysis of Building Response from Vertical Ground Motions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=George%20C.%20Yao">George C.

Most of the prevailing seismic codes assume the vertical component to be 1/2 to 2/3 of the horizontal one. In order to understand the building responses from vertical ground motions, many earthquakes records are studied in this paper. System identification methods (ARX Model) are used to analyze the strong motions and to find out the characteristics of the vertical amplification factors and the natural frequencies of buildings. Analysis results show that the vertical amplification factors for high-rise buildings and low-rise building are 1.78 and 2.52 respectively, and the average vertical amplification factor of all buildings is about 2. The relationship between the vertical natural frequency and building height was regressed to a suggested formula in this study. The result points out an important message; the taller the building is, the greater chance of resonance of vertical vibration on the building will be. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vertical%20ground%20motion" title="vertical ground motion">vertical ground motion</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20amplification%20factor" title=" vertical amplification factor"> vertical amplification factor</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20frequency" title=" natural frequency"> natural frequency</a>, <a href="https://publications.waset.org/abstracts/search?q=component" title=" component"> component</a> </p> <a href="https://publications.waset.org/abstracts/73421/analysis-of-building-response-from-vertical-ground-motions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73421.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">314</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2625</span> Percentile Reference Values of Vertical Jumping Performances and Anthropometric Characteristics in Athletic Tunisian Children and Adolescents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chirine%20Aouichaoui">Chirine Aouichaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Tounsi"> Mohamed Tounsi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ines%20Mrizak"> Ines Mrizak</a>, <a href="https://publications.waset.org/abstracts/search?q=Zouhair%20Tabka"> Zouhair Tabka</a>, <a href="https://publications.waset.org/abstracts/search?q=Yassine%20Trabelsi"> Yassine Trabelsi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to provide percentile values for vertical jumping performances and anthropometric characteristics for athletic Tunisian children. One thousand and fifty-five athletic Tunisian children and adolescents (643 boys and 412 girls) aged 7-18 years were randomly selected to participate in our study. They were asked to perform squat jumps and countermovement jumps. For each measurement, a least square regression model with high order polynomials was fitted to predict mean and standard deviation of vertical jumping parameters and anthropometric variables. Smoothed percentile curves and percentile values for the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles are presented for boys and girls. In conclusion, percentiles values of vertical jumping performances and anthropometric characteristics are provided. The new Tunisian reference charts obtained can be used as a screening tool to determine growth disorders and to estimate the proportion of adolescents with high or low muscular strength levels.

From the end of May 2015 in Kakheti after 25-year interruption, the work of anti-hail service was restored. Therefore, in connection with climate change, the need for the detailed study of the contemporary regime of the vertical distribution of the air temperature above this territory arose. In particular, the indicated information is necessary for the optimum selection of rocket means with the works on the weather modification (fight with the hail, the regulation of atmospheric precipitations, etc.). Construction of the detailed maps of the potential damage distribution of agricultural crops from the hail, etc. taking into account the dimensions of hailstones in the clouds according to the data of radar measurements and height of locality are the most important factors. For now, in Georgia, there is no aerological probing of atmosphere. To solve given problem we processed information about air temperature profiles above Telavi, at 27 km above earth's surface. Information was gathered during four observation time (4, 10, 16, 22 hours with local time. After research, we found vertical distribution of the average monthly values of the air temperature above Kakheti in ‎2012-2017 from January to December. Research was conducted from 0.543 to 27 km above sea level during four periods of research. In particular, it is obtained: -during January the monthly average air temperature linearly diminishes with 2.6 °C on the earth's surface to -57.1 °C at the height of 10 km, then little it changes up to the height of 26 km; the gradient of the air temperature in the layer of the atmosphere from 0.543 to 8 km - 6.3 °C/km; height of zero isotherm - is 1.33 km. -during July the air temperature linearly diminishes with 23.5 °C to -64.7 °C at the height of 17 km, then it grows to -47.5 °C at the height of 27 km; the gradient of the air temperature of - 6.1 °C/km; height of zero isotherm - is 4.39 km, which on 0.16 km is higher than in the sixties of past century. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hail" title="hail">hail</a>, <a href="https://publications.waset.org/abstracts/search?q=Kakheti" title=" Kakheti"> Kakheti</a>, <a href="https://publications.waset.org/abstracts/search?q=meteorology" title=" meteorology"> meteorology</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20distribution%20of%20the%20air%20temperature" title=" vertical distribution of the air temperature"> vertical distribution of the air temperature</a> </p> <a href="https://publications.waset.org/abstracts/84155/vertical-distribution-of-the-monthly-average-values-of-the-air-temperature-above-the-territory-of-kakheti-in-2012-2017" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84155.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">170</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2623</span> The Associations of Pes Planus Plantaris (Flat Foot) to the Postural Stability of Basketball Student-Athletes Through the Ground Reaction Force Vector (vGRF)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Def%20Primal">Def Primal</a>, <a href="https://publications.waset.org/abstracts/search?q=Sasanty%20Kusumaningtyas"> Sasanty Kusumaningtyas</a>, <a href="https://publications.waset.org/abstracts/search?q=Ermita%20I.%20Ibrahim"> Ermita I.

Methods: This cross-sectional quantitative analytical retrospective study on 47 subjects of basketball student-athletes identified the foot arch index by extensive footprint area and AMTI (Advanced Mechanical Technology Inc.) Force flat-form (force plate) determined their postural stability. Subjects were conducted in three activities (static, dynamic vertical jump, and dynamic loading response) for ground reaction force (GRF) resultant vectors towards the vertical plane of body mass (W). Results Analytical results obtained that 80.9% of subjects had pes planus plantaris. It shows no significant differences in pes planus plantaris incidence in both sexes subject (p>0.005); however, there are differences in athlete’s exercise period aspect. Athlete students who have practiced strictly for more than four years’ experience over 50% of pes planus plantaris; furthermore, a long period of exercise was believed to stimulate pes planus. The average value of GRF vectors of pes planus plantaris subjects on three different basketball movements shows a significant correlation to postural stability. Conclusions Pes planus plantaris affected almost basketball athletes regarding the length and intensity of exercise performed. The condition significantly contributes to postural stability disturbance on a static condition, dynamic vertical jump, and dynamic vertical jump loading response. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pes%20planus%20plantaris" title="pes planus plantaris">pes planus plantaris</a>, <a href="https://publications.waset.org/abstracts/search?q=flatfoot" title=" flatfoot"> flatfoot</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20reaction%20force" title=" ground reaction force"> ground reaction force</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20and%20dynamic%20stability" title=" static and dynamic stability"> static and dynamic stability</a> </p> <a href="https://publications.waset.org/abstracts/153583/the-associations-of-pes-planus-plantaris-flat-foot-to-the-postural-stability-of-basketball-student-athletes-through-the-ground-reaction-force-vector-vgrf" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153583.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">143</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2622</span> Relationship Between Dynamic Balance, Jumping Performance and Q-angle in Soccer Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tarik%20Ozmen">Tarik Ozmen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The soccer players need good dynamic balance and jumping performance for dribbling, crossing rival, and to be effective in high balls during soccer game. The quadriceps angle (Q-angle) is used to assess biomechanics of the patellofemoral joint in the musculoskeletal medicine. The Q angle is formed by the intersection of two lines drawing from the anterior superior iliac spine to the centre of the patella and to the midline of the tibia tuberosity. Studies have shown that the Q angle is inversely associated with quadriceps femoris strength. The purpose of this study was to investigate relationship between dynamic balance, jumping performance and Q-angle in soccer players. Thirty male soccer players (mean ± SD: age, 15.23 ± 0.56 years, height, 170 ± 8.37 cm, weight, 61.36 ± 6.04 kg) participated as volunteer in this study. Dynamic balance of the participants were evaluated at directions of anterior (A), posteromedial (PM) and posterolateral (PL) with Star Excursion Balance Test (SEBT). Each participant was instructed to reach as far as with the non-dominant leg in each of the 3 directions while maintaining dominant leg stance. Leg length was used to normalize excursion distances by dividing the distance reached by leg length and then multiplying the result by 100. The jumping performance was evaluated by squat jump using a contact mat. A universal (standard) goniometer was used to measure the Q angle in standing position. The Q angle was not correlated with directions of SEBT (A: p = 0.32, PM: p = 0.06, PL: p = 0.37). The squat jump height was not correlated with Q-angle (p = 0.21). The findings of this study suggest that there are no significant relationships between dynamic balance, jumping performance and Q-angle in soccer players. Further studies should investigate relationship between balance ability, athletic performance and Q-angle with larger sample size in soccer players. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=balance" title="balance">balance</a>, <a href="https://publications.waset.org/abstracts/search?q=jump%20height" title=" jump height"> jump height</a>, <a href="https://publications.waset.org/abstracts/search?q=Q%20angle" title=" Q angle"> Q angle</a>, <a href="https://publications.waset.org/abstracts/search?q=soccer" title=" soccer"> soccer</a> </p> <a href="https://publications.waset.org/abstracts/50053/relationship-between-dynamic-balance-jumping-performance-and-q-angle-in-soccer-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50053.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">457</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2621</span> Effect of Angles Collision, Absorption, Dash and Their Relationship with the Finale Results Case the Algerian Elite Team Triple Jump</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Guebli%20Abdelkader">Guebli Abdelkader</a>, <a href="https://publications.waset.org/abstracts/search?q=Zerf%20Mohammed"> Zerf Mohammed</a>, <a href="https://publications.waset.org/abstracts/search?q=Mekkades%20Moulay%20Idriss"> Mekkades Moulay Idriss</a>, <a href="https://publications.waset.org/abstracts/search?q=BenGoua%20Ali"> BenGoua Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Atouti%20Nouredinne"> Atouti Nouredinne</a>, <a href="https://publications.waset.org/abstracts/search?q=Habchi%20Nawel"> Habchi Nawel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper aims to show the influence of angles in the results of triple jump.

The adequate tailwater level that ensures the hydraulic jump inside the basin should be fulfilled by the river's natural water level and the apron depth downstream of the chute. The requirements of the hydraulic jump should mainly be checked for the design flood, however, the drawn jump condition should not be critical in the discharges lesser than the design flood. The tailwater requirement is not met in Almatti dam, built in 2005 in India, and the jump sweep out from the basin, resulting in significant scour in the apron and end sill of the basin. This paper discusses different hydraulic solutions as sustainable solutions for the rehabilitation program. The deep apron alternative is proposed for the fewer bays of the spillway as the most cost-effective, sustainable solution.

This study was undertaken to find out the effect of gymnastic oriented training program on the physical fitness and the level of technical performance of basketball players. Method: 27 basketballers were divided into 12 experimental and 15 control groups aged between 19 to 25 years. Physical fitness tests comprising of vertical jump, push-ups, chin ups, sit ups, back strength, 30 m sprint, boomerangs test, 600 m run, sit and reach, bridge up and shoulder rotation and technical skill tests like dribbling, layup shots and rebound collection were used for the study. A pre- and post-test was conducted before and after the training program of 6 weeks. Results: The results indicated no significant difference in the anthropometric measurements of age, height and weight between the experimental and control group as the ‘t’ values observed were 0.28, 1.63 and 1.60 respectively . There were significant improvements in vertical jump, push-ups, sit-ups, modified boomerang test, bridge test and shoulder rotation index with the ‘t’ values being 2.60, 3.41, 3.91, 4.02, 3.55 and 2.33 respectively. However, no significant differences existed in chin-ups, back strength, 30 m sprint and 6000 m run with the ‘t’ values being 2.08, 1.77, 1.28 and 0.80 respectively. There was significant improvement in the post-test for the technical skills tests in the experimental group with ‘t’ values being 3.65, 2.57, and 3.62 for the dribble, layup shots and rebound collection respectively. There was no significant difference in the values of the control group except in the rebound collection which showed significant difference. Conclusion: It was found that both the physical fitness and skill proficiency of the basketballers increased through the participation in the gymnastics oriented program. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gymnastic" title="gymnastic">gymnastic</a>, <a href="https://publications.waset.org/abstracts/search?q=technical" title=" technical"> technical</a>, <a href="https://publications.waset.org/abstracts/search?q=pre-requisite" title=" pre-requisite"> pre-requisite</a>, <a href="https://publications.waset.org/abstracts/search?q=elite%20class" title=" elite class"> elite class</a> </p> <a href="https://publications.waset.org/abstracts/10621/gymnastics-oriented-training-program-impact-of-6-weeks-training-on-the-fitness-and-performance-of-basketball-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10621.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">401</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2615</span> New Segmentation of Piecewise Moving-Average Model by Using Reversible Jump MCMC Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suparman">Suparman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper addresses the problem of the signal segmentation within a Bayesian framework by using reversible jump MCMC algorithm.

The reversible jump MCMC algorithm is then used to generate samples distributed according to the joint posterior distribution of the unknown parameters. These samples allow calculating some interesting features of the posterior distribution.

Effective way of improving the properties of the cast magnesium alloy AZ31 (3 wt. % Al, 0.8 wt. % Zn, 0.2 wt. % Mn)) is to combine hot extrusion at 350°C and equal-channel angular pressing (ECAP) at 180°C. Because of reduced grain sizes, changes in the nature of the grain boundaries, and enhancement of a texture that favors basal dislocation glide, after this kind of processing, increase yield stress and ductility. For study of the effect of microstructure on the mechanisms for plastic deformation, there is some interest in investigating the mechanical properties of the ultrafinegrained (UFG) Mg alloy at low temperatures, before and after annealing. It found that the amplitude and statistics at the low-temperature jump-like deformation the Mg alloy of dependent on microstructure. Reduction of the average density of dislocations and grain growth during annealing causing a reduction in the amplitude of the jump-like deformation and changes in the distribution of surges in amplitude. It found that the amplitude and statistics at the low-temperature jump-like deformation UFG alloy dependent on temperature of deformation. Plastic deformation of UFG alloy at a temperature of 10 K occurs uniformly - peculiarities is not observed. Increasing of the temperature of deformation from 4,2 to 0,5 K is causing a reduction in the amplitude and increasing the frequency of the jump-like deformation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=jump-like%20deformation" title="jump-like deformation">jump-like deformation</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20temperature" title=" low temperature"> low temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=plasticity" title=" plasticity"> plasticity</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20alloy" title=" magnesium alloy"> magnesium alloy</a> </p> <a href="https://publications.waset.org/abstracts/53749/jump-like-deformation-of-ultrafinegrained-az31-at-temperature-42-05-k" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53749.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">455</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2613</span> Basket Option Pricing under Jump Diffusion Models</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Safdari-Vaighani">Ali Safdari-Vaighani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Pricing financial contracts on several underlying assets received more and more interest as a demand for complex derivatives. The option pricing under asset price involving jump diffusion processes leads to the partial integral differential equation (PIDEs), which is an extension of the Black-Scholes PDE with a new integral term. The aim of this paper is to show how basket option prices in the jump diffusion models, mainly on the Merton model, can be computed using RBF based approximation methods. For a test problem, the RBF-PU method is applied for numerical solution of partial integral differential equation arising from the two-asset European vanilla put options.

Anterior Cruciate Ligament (ACL) injury is common in racquet sports and often occurs due to sudden acceleration, deceleration or changes of direction. This mechanism in badminton most commonly occurs during landing after an overhead stroke. Knee biomechanics during dynamic movements such as walking, running and stair negotiation, do not return to normal for more than a year after an ACL reconstruction. This change in the biomechanics may lead to re-injury whilst performing non-steady movements during sports, where these injuries are most prevalent. Aims: To compare if the knee kinetics and kinematics in ACL injury recovered athletes return to the same level as those from an uninjured cohort during standard movements used for clinical assessment and badminton shots. Objectives: The objectives of the study were to determine: Knee valgus during the single leg squat, vertical drop jump, net shot and drop shot; Degree of internal or external rotation during the single leg squat, vertical drop jump, net shot and drop shot; Maximum knee flexion during the single leg squat, vertical drop jump and net shot. Methods: This case-control study included 14 participants with three ACL injury recovered athletes and 11 uninjured participants. The participants performed various functional tasks including vertical drop jump, single leg squat; the forehand net shot and the forehand drop shot. The data was analysed using the two-way ANOVA test, and the reliability of the data was evaluated using the Intra Class Coefficient. Results: The data showed a significant decrease in the range of knee rotation in ACL injured participants as compared to the uninjured cohort (F₇,₅₅₆=2.37; p=0.021). There was also a decrease in the maximum knee flexion angles and an increase in knee valgus angles in ACL injured participants although they were not statistically significant. Conclusion: There was a significant decrease in the knee rotation angles in the ACL injured participants which could be a potential cause for re-injury in these athletes in the future. Although the results for decrease in maximum knee flexion angles and increase in knee valgus angles were not significant, this may be due to a limited sample of ACL injured participants; there is potential for it to be identified as a variable of interest in the rehabilitation of ACL injuries. These changes in the knee biomechanics could be vital in the rehabilitation of ACL injured athletes in the future, and an inclusion of sports based tasks, e.g., Net shot along with standard protocol movements for ACL assessment would provide a better measure of the rehabilitation of the athlete. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ACL" title="ACL">ACL</a>, <a href="https://publications.waset.org/abstracts/search?q=biomechanics" title=" biomechanics"> biomechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=knee%20injury" title=" knee injury"> knee injury</a>, <a href="https://publications.waset.org/abstracts/search?q=racquet%20sport" title=" racquet sport"> racquet sport</a> </p> <a href="https://publications.waset.org/abstracts/81747/comparing-the-knee-kinetics-and-kinematics-during-non-steady-movements-in-recovered-anterior-cruciate-ligament-injured-badminton-players-against-an-uninjured-cohort-case-control-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81747.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">174</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2611</span> Post-Exercise Effects of Cold Water Immersion over a 48-Hour Recovery Period on the Physical and Haematological Parameters of Male University-Level Rugby Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Adele%20Broodryk">Adele Broodryk</a>, <a href="https://publications.waset.org/abstracts/search?q=Cindy%20Pienaar"> Cindy Pienaar</a>, <a href="https://publications.waset.org/abstracts/search?q=Martinique%20Sparks"> Martinique Sparks</a>, <a href="https://publications.waset.org/abstracts/search?q=Ben%20Coetzee"> Ben Coetzee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Cold water immersion (CWI) is a popular recovery modality utilised. However, discrepancies exist regarding the results over a 48 hour recovery period. Aim: To evaluate the effects of CWI and passive recovery (PAR) on a range of haematological and physical parameters over a 48-hour using a cross-sectional, pre-post-test design. Subjects and Methods: Both the and physical parameters were evaluated at baseline, after a 15-min fitness session, and at 0, 24 and 48 hours post-recovery in 23 male university rugby players. The CWI group sat in a cold water pool (8°C) for 20 min whereas the PAR group remained seated. Results: At 0 hours post-CWI, three (blood lactate (BLa-), Sodium (Na+) and haemoglobin) returned to baseline values, however Vertical Jump Test (VJT) height results decreased whereas after PAR it improved. From 0 to 24 and/or 48 h, four (Partial Oxygen (PO2) VJT-height, plasma glucose, and Na+) significantly increased (p ≤ 0.05) in either and/or both groups. Significant intergroup differences (p ≤ 0.05) were noticed in the physical tests. Conclusions: PAR is superior as an acute modality (0 hours) due to CWI cooling the body down. However, CWI demonstrates advantageous over a 24-hour period in a wide range of haematological variables. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cryotherapy" title="cryotherapy">cryotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=recuperation" title=" recuperation"> recuperation</a>, <a href="https://publications.waset.org/abstracts/search?q=haematological" title=" haematological"> haematological</a>, <a href="https://publications.waset.org/abstracts/search?q=rugby" title=" rugby"> rugby</a> </p> <a href="https://publications.waset.org/abstracts/46687/post-exercise-effects-of-cold-water-immersion-over-a-48-hour-recovery-period-on-the-physical-and-haematological-parameters-of-male-university-level-rugby-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/46687.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">264</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2610</span> Whitnall’s Sling Will Be an Alternative Method for the Surgical Correction of Poor Function Ptosis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Titap%20Yazicioglu">Titap Yazicioglu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To examine the results of two different surgery in patients with severe ptosis and poor levator function.

Preoperative diagnosis for all patients was noted as, the average LF was 3.4±0.51mm, vertical lid height was 3.5±0.52 mm and margin reflex distance-1 (MRD-1) was 0.4±0.51mm. The mean vertical lid height was measured as 7.1±0.73 mm in the frontalis sling group and 7.2±0.63 mm in the Whitnall’s sling group at the postoperative 1st month control. However, in patients with Whitnall’s sling, revision was performed with frontalis sling surgery due to failure in vertical lid height in the late postoperative period, and an average of 7.5±0.52 mm was achieved. Satisfactory results were obtained in all patients. Although postoperative lagophthalmitis developed in the frontalis sling group, none of them developed exposure keratitis. Granuloma was observed as sling infection in 2(20%) of the patients. Although Whitnall’s sling technique provides a natural look appearance without interfering with the functional result, we did not find it as successful as frontalis sling surgery in severe ptosis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=congenital%20ptosis" title="congenital ptosis">congenital ptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=frontalis%20suspension" title=" frontalis suspension"> frontalis suspension</a>, <a href="https://publications.waset.org/abstracts/search?q=Whitnall%20ligament" title=" Whitnall ligament"> Whitnall ligament</a>, <a href="https://publications.waset.org/abstracts/search?q=complications" title=" complications"> complications</a> </p> <a href="https://publications.waset.org/abstracts/152124/whitnalls-sling-will-be-an-alternative-method-for-the-surgical-correction-of-poor-function-ptosis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152124.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">106</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2609</span> Eight Weeks of Suspension Systems Training on Fat Mass, Jump and Physical Fitness Index in Female</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Che%20Hsiu%20Chen">Che Hsiu Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Su%20Yun%20Chen"> Su Yun Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Hon%20Wen%20Cheng"> Hon Wen Cheng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Greater core stability may benefit sports performance by providing a foundation for greater force production in the upper and lower extremities. Core stability exercises on instability device (such as the TRX suspension systems) were found to be able to induce higher core muscle activity than performing on a stable surface. However, high intensity interval TRX suspension exercises training on sport performances remain unclear. The purpose of this study was to examine whether high intensity TRX suspension training could improve sport performance. Twenty-four healthy university female students (age 19.0 years, height 157.9 cm, body mass 51.3 kg, fat mass 25.2 %) were voluntarily participated in this study. After a familiarization session, each participant underwent five suspension exercises (e.g., hip abduction in plank alternative, hamstring curl, 45-degree row, lunge and oblique crunch). Each type of exercise was performed for 30 seconds, followed by 30 seconds break, two times per week for eight weeks while each exercise session was increased by 10 seconds every week. The results showed that the fat mass (about 12.92%) decreased significantly, sit and reach test (9%), 1 minute sit-up test (17.5%), standing broad jump (4.8%), physical fitness index (10.3%) increased significantly after 8-week high intensity TRX suspension training. Hence, eight weeks of high intensity interval TRX suspension exercises training can improve hamstring flexibility, trunk endurance, jump ability, aerobic fitness and fat mass percentage decreased substantially. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=core%20endurance" title="core endurance">core endurance</a>, <a href="https://publications.waset.org/abstracts/search?q=jump" title=" jump"> jump</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiovascular%20fitness" title=" cardiovascular fitness"> cardiovascular fitness</a> </p> <a href="https://publications.waset.org/abstracts/50791/eight-weeks-of-suspension-systems-training-on-fat-mass-jump-and-physical-fitness-index-in-female" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50791.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">408</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2608</span> Effect of Kinesio Taping on Anaerobic Power and Maximum Oxygen Consumption after Eccentric Exercise</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Disaphon%20Boobpachat">Disaphon Boobpachat</a>, <a href="https://publications.waset.org/abstracts/search?q=Nuttaset%20Manimmanakorn"> Nuttaset Manimmanakorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Apiwan%20Manimmanakorn"> Apiwan Manimmanakorn</a>, <a href="https://publications.waset.org/abstracts/search?q=Worrawut%20Thuwakum"> Worrawut Thuwakum</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20J.%20Hamlin"> Michael J.

Methods: Thirty nine untrained healthy volunteers were randomized to 3 groups for each intervention: elastic tape, placebo tape and stretching. The participants performed intensive exercise on the dominant quadriceps by using isokinetic dynamometry machine. The recovery process was evaluated by creatine kinase (CK), pressure pain threshold (PPT), muscle soreness scale (MSS), maximum voluntary contraction (MVC), jump height, anaerobic power and Vo₂max at baseline, immediately post-exercise and post-exercise day 1, 2, 3 and 7. Results: The kinesio tape, placebo tape and stretching groups had significant changes of PPT, MVC, jump height at immediately post-exercise compared to baseline (p < 0.05), and changes of MSS, CK, anaerobic power and Vo₂max at day 1 post-exercise compared to baseline (p < 0.05). There was no significant difference of those outcomes among three groups. Additionally, all experimental groups had little effects on anaerobic power and Vo₂max compared to baseline and compared among three groups (p > 0.05). Conclusion: Kinesio tape and stretching did not improve recovery of anaerobic power and Vo₂max after eccentric exercise compared to placebo tape. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stretching" title="stretching">stretching</a>, <a href="https://publications.waset.org/abstracts/search?q=eccentric%20exercise" title=" eccentric exercise"> eccentric exercise</a>, <a href="https://publications.waset.org/abstracts/search?q=Wingate%20test" title=" Wingate test"> Wingate test</a>, <a href="https://publications.waset.org/abstracts/search?q=muscle%20soreness" title=" muscle soreness"> muscle soreness</a> </p> <a href="https://publications.waset.org/abstracts/103341/effect-of-kinesio-taping-on-anaerobic-power-and-maximum-oxygen-consumption-after-eccentric-exercise" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/103341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">130</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2607</span> Experimental Investigation for the Overtopping Wave Force of the Vertical Breakwater</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jin%20Song%20Gui">Jin Song Gui</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Li"> Han Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Rui%20Jin%20Zhang"> Rui Jin Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Heng%20Jiang%20Cai"> Heng Jiang Cai</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is a large deviation between the measured wave power at the vertical breast wall and the calculated one according to current specification in the case of overtopping. In order to investigate the reasons for the deviation, the wave forces of vertical breast wall under overtopping conditions have been measured through physical model experiment and compared with the calculated results. The effect of water depth, period and the wave height on the wave forces of the vertical breast wall have been also investigated. The distribution of wave pressure under different wave actions was tested based on the force sensor which is installed in the vertical breakwater. By comparing and analyzing the measured values and norms calculated values, the applicability of the existing norms recommended method were discussed and a reference for the design of vertical breakwater was provided. Experiment results show that with the decrease of the water depth, the gap is growing between the actual wave forces and the specification values, and there are no obvious regulations between these two values with the variation of period while wave force greatly reduces with the overtopping reducing. The amount of water depth and wave overtopping has a significant impact on the wave force of overtopping section while the period has no obvious influence on the wave force. Finally, some favorable recommendations for the overtopping wave force design of the vertical breakwater according to the model experiment results are provided. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=overtopping%20wave" title="overtopping wave">overtopping wave</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20model%20experiment" title=" physical model experiment"> physical model experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=vertical%20breakwater" title=" vertical breakwater"> vertical breakwater</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20forces" title=" wave forces"> wave forces</a> </p> <a href="https://publications.waset.org/abstracts/47386/experimental-investigation-for-the-overtopping-wave-force-of-the-vertical-breakwater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47386.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">303</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2606</span> Determining Components of Deflection of the Vertical in Owerri West Local Government, Imo State Nigeria Using Least Square Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chukwu%20Fidelis%20Ndubuisi">Chukwu Fidelis Ndubuisi</a>, <a href="https://publications.waset.org/abstracts/search?q=Madufor%20Michael%20Ozims"> Madufor Michael Ozims</a>, <a href="https://publications.waset.org/abstracts/search?q=Asogwa%20Vivian%20Ndidiamaka"> Asogwa Vivian Ndidiamaka</a>, <a href="https://publications.waset.org/abstracts/search?q=Egenamba%20Juliet%20Ngozi"> Egenamba Juliet Ngozi</a>, <a href="https://publications.waset.org/abstracts/search?q=Okonkwo%20Stephen%20C."> Okonkwo Stephen C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamah%20Chukwudi%20David"> Kamah Chukwudi David</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Deflection of the vertical is a quantity used in reducing geodetic measurements related to geoidal networks to the ellipsoidal plane; and it is essential in Geoid modeling processes. Computing the deflection of the vertical component of a point in a given area is necessary in evaluating the standard errors along north-south and east-west direction. Using combined approach for the determination of deflection of the vertical component provides improved result but labor intensive without appropriate method. Least square method is a method that makes use of redundant observation in modeling a given sets of problem that obeys certain geometric condition. This research work is aimed to computing the deflection of vertical component of Owerri West local government area of Imo State using geometric method as field technique. In this method combination of Global Positioning System on static mode and precise leveling observation were utilized in determination of geodetic coordinate of points established within the study area by GPS observation and the orthometric heights through precise leveling. By least square using Matlab programme; the estimated deflections of vertical component parameters for the common station were -0.0286 and -0.0001 arc seconds for the north-south and east-west components respectively. The associated standard errors of the processed vectors of the network were computed. The computed standard errors of the North-south and East-west components were 5.5911e-005 and 1.4965e-004 arc seconds, respectively. Therefore, including the derived component of deflection of the vertical to the ellipsoidal model will yield high observational accuracy since an ellipsoidal model is not tenable due to its far observational error in the determination of high quality job. It is important to include the determined deflection of the vertical component for Owerri West Local Government in Imo State, Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deflection%20of%20vertical" title="deflection of vertical">deflection of vertical</a>, <a href="https://publications.waset.org/abstracts/search?q=ellipsoidal%20height" title=" ellipsoidal height"> ellipsoidal height</a>, <a href="https://publications.waset.org/abstracts/search?q=least%20square" title=" least square"> least square</a>, <a href="https://publications.waset.org/abstracts/search?q=orthometric%20height" title=" orthometric height"> orthometric height</a> </p> <a href="https://publications.waset.org/abstracts/99755/determining-components-of-deflection-of-the-vertical-in-owerri-west-local-government-imo-state-nigeria-using-least-square-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99755.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2605</span> New Segmentation of Piecewise Linear Regression Models Using Reversible Jump MCMC Algorithm</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suparman">Suparman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Piecewise linear regression models are very flexible models for modeling the data. If the piecewise linear regression models are matched against the data, then the parameters are generally not known. This paper studies the problem of parameter estimation of piecewise linear regression models. The method used to estimate the parameters of picewise linear regression models is Bayesian method. But the Bayes estimator can not be found analytically. To overcome these problems, the reversible jump MCMC algorithm is proposed. Reversible jump MCMC algorithm generates the Markov chain converges to the limit distribution of the posterior distribution of the parameters of picewise linear regression models. The resulting Markov chain is used to calculate the Bayes estimator for the parameters of picewise linear regression models. <p class="card-text"><strong>Keywords:</strong> <a
