• Description:
  The main objective of this paper was to study the effects of frequency of lift, weight of load, and age of workers on the endurance time and the human physiological capabilities for prolonged lifting tasks performed from table to shoulder height. To achieve this objective an experiment was conducted in a laboratory of controlled temperature and humidity. Age of subjects, frequency of lift, and weight of load were the independent variables. Endurance time, heart rate, oxygen consumption, and minute ventilation were the dependent variables. Some of the main findings obtained from this study were: (1) the endurance time of a person is decreased considerably with the weight of load and/or frequency of lift; (2) the physiological fatigue limit is a function of lifting task parameters; and (3) both the weight of load and frequency of lift appeared to have equal effect on endurance time and physiological responses.
