	%X The purpose of this study was to measure the maximal
isometric strength and to investigate the effects of different handleheights
and elbow angles with respect to Mid. sagittal plane on the
pushing and pulling strength in vertical direction. 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.
