Isokinetic pull strengths in the vertical plane: effects of speed and arm angle

The significance of knowing dynamic (isokinetic) strengths of individuals and the impact of selected individual and work-related factors on these strengths have been addressed in previous works. This follow-up study investigated the effects of pulling speed and angle of the preferred arm on isokinetic strengths of males and females in a vertical plane. The results indicated that speed of pulling has a major influence on strength exertion capabilities of people. Isokinetic strength exertions are maximum in the vertical plane but are smaller than isometric strength exertions in the vertical plane. As expected, men exerted greater force than females. Force exertions in the sitting and standing postures were not appreciably different from each other.
