Abstract : The purpose of this investigation was to determine the effectiveness of psychophysical lifting training on maximal repetitive lifting capacity. Maximal repetitive lifting capacity was defined as the maximum box mass that could be lifted for a full hour to a height of 132 cm at a rate of 6 lifts per minute. Eight male subjects participated in five psychophysical lifting training sessions each week for four weeks. Each day subjects were presented one empty and one heavily loaded box and asked to adjust to the maximum load they felt capable of lifting for one hour. This load was lifted at a rate of 6 lifts per minute to a height of 132 cm for two 15 minute sessions. After four weeks of training, subjects did not select a heavier ratings of perceived exertion. The training program produced a significant increase in one hour maximal repetitive lifting capacity. The box mass selected for the maximal repetitive lifting capacity test increased significantly following training, with no concomitant change in VO2, heart rate or RPE. Keywords: Repetitive lifting, Training, Maximal exercise.
