Abstract

The main objective of this study is to investigate the effect of weight of load, frequency of handling, and age of industrial workers on endurance time and physiological responses for prolonged lifting tasks from shoulder to reach height, to Sixteen male industrial workers participated in this study. The independent variables were the frequency of handling, the weight of load, and the age of workers. The dependent variables were endurance time, oxygen consumption, minute ventilation, heart rate and the subjective response of the subjects (ratings of perceived exertion). The results indicated that (1) endurance time decreased with increasing frequency or load, (2) Endurance time, heart rate, oxygen consumption and minute ventilation were significantly affected by frequency and load. (3) Age did not have a significant effect on endurance time, heart rate and oxygen consumption but it was significant for minute ventilation.
