Physiological Determinants of Load Bearing Capacity

摘要

This study identifies some of the physiological determinants of load bearing capacity. Although it is reasonable to assume that maximal aerobic capacity (VO2) is an important determinant of load bearing ability, research implicating the importance of muscular strength and endurance of the lower extremities in load bearing activity has not been reported. To address this deficiency, 49 infantrymen were measured for: 1) aerobic capacity, 2) muscular strength of the quadriceps and hamstrings 3) muscular endurance of the quadriceps and hamstrings and 4) body composition. following these measures, the infantrymen made a maximal effort 10-mile road march with battle dress dress equipment. These data suggest that hamstring muscle strength may be an important determinanat of prolonged load bearing performance. Further research may elucidate the degree to which aerobic capacity, muscle strength, and other physiological variables independently and/or interactively influence load bearing capacity.
