Abstract

The primary objective of the present study was to explore whether the human machine has an optimal value or a range where it performs at maximum physiological efficiency during repetitive lifting tasks. Ten trained male subjects participated in this study. The frequency of lift and height of lift were the independent variables. The psychophysical methodology was employed in this investigation. Maximum physiological efficiency is defined as the power output per unit oxygen consumption. The results indicated that for maximum physiological efficiency in repetitive lifting tasks of a duration of 1/2 hour the frequency of lift should be between 5 and 11 lifts/min with 9 lifts/min being optimal.
