Twenty college-age women participated in a ten-week physical training program involving two intensities of exercise. Eleven women trained at a relatively high exercise intensity (HI) of 840 kgm/min while nine women trained at a low exercise intensity (LI) of 420 kgm/min. Body composition and residual lung volume changes were analyzed before and after the training program for both groups. There were no significant changes in body weight, body density, percent body fat, lean body weight and residual lung volume for the HI group. The LI group exhibited a significant increase in body density (0.0026 density units) and significant decreases in percent fat (1.1%) and residual lung volume (67 ml). Closed circuit metabolic measures indicated that the HI group was working anaerobically for at least a portion of each minute. Results of the study support the contention that to reduce body fat stores an exercise program of low intensity and long duration is required.
二十名大学适龄女性参加了一项为期十周的体育训练计划，该计划包含两种运动强度。十一名女性以相对较高的运动强度（HI）840千克米/分钟进行训练，而九名女性以较低的运动强度（LI）420千克米/分钟进行训练。对两组训练前后的身体成分和残气量变化进行了分析。HI组的体重、身体密度、体脂百分比、去脂体重和残气量均无显著变化。LI组的身体密度显著增加（0.0026密度单位），体脂百分比显著下降（1.1%），残气量显著下降（67毫升）。闭路代谢测量表明，HI组每分钟至少有一部分时间处于无氧工作状态。该研究结果支持了这样一种观点，即要减少体内脂肪储存，需要进行低强度、长时间的运动计划。
