Eight male subjects performed a series of static strength measurement for each subject. The highest isometric strength was found in pulling at shoulder height (S.H.) (Mean 60.29 lb., SD 16.78 lb.) and the lowest isometric strength was found also in pulling at elbow height (E.H.) (Mean 33.06 lb., SD 6.56 lb.). Although the isometric strengths were higher at S.H than at E.H. for both activities, the maximal isometric strengths were compared statistically. ANOVA was performed. The results of the experiment revealed that there was a significant different between handle heights. However, there were no significant different between angles and activities, also no correlation between grip strength and activities.</abstract> <index>Open Science Index 23, 2008</index> </article>
