A study was conducted to compare dynamic lifting task with a simulated static lifting task. 17 subjects - 12 males and 5 females - volunteered to participate in this study. The independent variables were the type of task (static and dynamic), frequency of lift (2, 4, and 6 lifts/min), and muscle group (back lift, leg lift, and arm lift). The psychophysical methodology was used in this study. The results showed highly significant differences between maximum acceptable static effort (MASE) and maximum acceptable dynamic effort (MADE) for both males and females. The frequency was also statistically significant. The muscle groups were significant for females and not significant for males.
