The effects of caloric restriction and exercise on body composition, resting metabolic rate (RMR), and maximal oxygen uptake (VO2 max) were studied for 16 wk in 26 premenopausal obese women. Exercise (X) vs nonexercise (NX) was crossed with a low-fat, ad libitum-carbohydrate (AL) diet vs a restricted (R) (800 kcal) low-fat, high-carbohydrate diet in a 2 x 2 factorial design. Subjects were randomly assigned to one of the four treatment groups. Body-weight and percent-fat losses were significant (p less than 0.05) in all groups but greater in subjects assigned to the R diet (p less than 0.05) and/or X (p less than 0.10) groups. Exercise increased (p less than 0.01) VO2 max but neither exercise nor diet influenced fat-free mass or RMR (kcal.m-2.h-1), both of which remained unchanged over time. A program similar to that followed by the ALX group is recommended for long-term weight control and overall health.
对26名绝经前肥胖女性进行了为期16周的研究，以探讨热量限制和运动对身体成分、静息代谢率（RMR）和最大摄氧量（VO2 max）的影响。采用2×2析因设计，将运动（X）与不运动（NX）与低脂、随意碳水化合物（AL）饮食与限制（R）（800千卡）低脂、高碳水化合物饮食进行交叉。受试者被随机分配到四个治疗组之一。所有组的体重和脂肪百分比下降均显著（p<0.05），但在接受R饮食（p<0.05）和/或X（p<0.10）组的受试者中下降幅度更大。运动增加了（p<0.01）VO2 max，但运动和饮食均未影响去脂体重或RMR（千卡·平方米·小时-1），两者随时间均保持不变。建议采用与ALX组类似的方案进行长期体重控制和整体健康管理。
