确定有氧或阻力训练对减肥后活动相关能量消耗（AEE, kcal/d）和身体活动指数（ARTE）的影响。假设没有运动训练的体重减轻会伴随着AEE、ARTE和非训练体力活动能量消耗（NEAT）的减少，并且运动训练可以防止自由生活能量消耗的减少。140名绝经前妇女在每天800千卡的膳食中平均减轻了25磅的体重。一组有氧训练3次/周（40分钟/天），另一组阻力训练3次/周（10次/2组x10次重复），第三组不运动。DXA测量身体成分，间接量热法测量静息（REE）和步行能量消耗，双标记水测量总能量消耗（TEE）。计算AEE、ARTE和非训练体力活动能量消耗（NEAT）。无运动组的TEE、REE和NEAT在减肥后都有所下降，但有氧和阻力训练组没有。只有REE在两个运动组中下降。抗阻训练员增加了ARTE。在平地上行走时的心率和摄氧量与TEE、AEE、NEAT和ARTE一致相关。运动训练可以防止减肥后能量消耗的减少，包括与运动训练分开的自由生活能量消耗。阻力训练增加了身体活动，而步行的便利性和经济性与TEE、AEE、NEAT和ARTE的增加有关。
Determine the effects of aerobic or resistance training on activity related energy expenditure (AEE, kcal/d) and physical activity index (ARTE) following weight loss. It was hypothesized that weight loss without exercise training would be accompanied by a decrease in AEE, ARTE, and non-training physical activity energy expenditure (NEAT) and that exercise training would prevent decreases in free living energy expenditure. 140 pre-menopausal women underwent an average of 25 pound weight loss during an 800 kcal/day diet of furnished food. One group aerobically trained 3 times/wk (40 min/d), another resistance trained 3 times/wk (10 exercises/2 sets x10 repetitions) and the third group did not exercise. DXA was used to measure body composition, indirect calorimetry to measure resting (REE) and walking energy expenditure, and doubly labeled water to measure total energy expenditure (TEE). AEE, ARTE, and non-training physical activity energy expenditure (NEAT) were calculated. TEE, REE, and NEAT all decreased following weight loss for the no exercise group, but not for the aerobic and resistance trainers. Only REE decreased in the two exercise groups. The resistance trainers increased ARTE. Heart rate and oxygen uptake while walking on the flat and up a grade were consistently related to TEE, AEE, NEAT, and ARTE. Exercise training prevents a decrease in energy expenditure, including free living energy expenditure separate from the exercise training, following weight loss. Resistance training increased physical activity, while ease and economy in walking associates with increased TEE, AEE, NEAT, and ARTE.
