Strength testing is a tool used by industry, to evaluate the maximum strength of their employees, and to prepare tasks that fit employee capabilities. This study compared the static arm strength of holding a handle with a 90° elbow flexion between twenty-three participants. This study used two different strength test systems: one consisted of a solid setup, and the other one utilized a chain setup, to compare the three-second maximum pull strength. Additionally, the chain setup system test was used to compare three seconds with five-second maximum pull strengths. Results indicated that the solid system resulted in significantly higher strength data in comparison to the chain setup system tested for 3 seconds. No significant effect of test duration (3s vs. 5s) was found for the measures using the chain setup system. Moreover, the differences between the handles on the two systems may contribute to the differences in results.
