Abstract
A study was conducted on how much weight young males, aged 22 to 30 years, could safely lift. It was pointed out that injuries due to overexertion are costly in terms of both lost working time and personal pain and suffering. Although several investigations have been concerned with safe lifting, the authors noted that none of them had discussed lifting from a sitting position. Eight physically active males without a history of low back pain or other musculoskeletal problems participated in the study. Their age, body weight, physical stature and maximal oxygen consumption were recorded. Before data collection was started, the subjects completed six training sessions of 45 minutes each. Four of the lifting sessions were carried out in a sitting position and two standing. The four test positions were illustrated. The data for weights lifted, oxygen consumption, heart rate, and perceived exertion were reported for the various lifting positions and frequencies. The results suggested that the maximal acceptable lift in a sitting position is less than that which is acceptable in a standing position. The authors recommend that the acceptable weightlift from table height to shoulder height should be 16 percent less when the subject is seated than when he is standing.
