The objective of this research was to study the effects of task parameters on physiological and psychophysical limits for prolonged lifting activities. The results of this study indicate that (1) The endurance time of individuals decreased with the increase of the frequency and the weight of load, and (2) physiological responses are dependent on lifting task parameters.
