Abstract

In the occupational setting, strength testing is a tool widely used in order to understand workers’ strength capabilities. Static arm strength is typically measured with the subject in a standing posture, with the forearm at a right angle to the upper arm. The subject is instructed to lift with the arms, while minimizing any contributions from the legs or back. This study attempted to eliminate the leg contributions to static arm strength by comparing the maximal isometric strength that can be generated by the arm muscles in sit and stand postures. The Jackson strength evaluation system was used for this purpose. Results indicated that there were no significant differences in the arm strengths between the two postures for both males and females. More specifically, no significant differences were found between the peak and average arm strengths between the sit and stand conditions in both the sexes. In addition, no learning effect was found between the trials for all conditions excep
