本研究探讨了运动训练是否有助于通过减弱减肥引起的静息代谢和脂肪氧化减少来维持体重在减肥后降低的水平。研究了18名最近平均减重9 ± 1 kg的老年受试者（平均± SE，61 ± 1岁;范围，56 - 70），12周（每周3次）有氧或重量训练运动对休息期间和餐后体重、身体成分和能量代谢的影响。在运动训练期间，有氧训练组（5名女性，4名男性）与重量训练组（5名女性，4名男性）（0.4 +/- 0.9 kg）相比，体重（-2.5 +/- 0.6 kg）显著（P <0.05）降低。9名有氧训练受试者中有8名体重减轻，而9名重量训练受试者中有6名体重增加。这两种类型的训练都不能逆转由于先前的体重减轻而发生的静息代谢或脂肪氧化率（无论是在静息时还是餐后）的下降。因此，静息代谢或脂肪氧化（静息或餐后）的改变似乎不是运动训练促进维持饮食诱导的体重减轻的机制。(C)1996年，W.B.桑德斯公司
This study examined whether exercise training facilitates maintenance of body weight at reduced levels following weight loss by attenuating weight loss-induced reductions in resting metabolism and fat oxidation. The effects of 12 weeks (three times per week) of either aerobic or weight training exercise on body weight, body composition, and energy metabolism during rest and following a meal in 18 older (mean +/- SE, 61 +/- 1 years; range, 56 to 70) subjects who had recently lost a mean of 9 +/- 1 kg were studied. During the exercise training period, the aerobic training group (five women, four men) had a significant (P < .05) reduction in body weight (-2.5 +/- 0.6 kg) as compared with the weight training group (five women, four men) (0.4 +/- 0.9 kg). Eight of nine aerobic training subjects lost additional weight, while six of nine weight training subjects gained weight. Neither type of training reversed the depressions in resting metabolism or fat oxidation rates tie, resting or postprandial) that had occurred as a consequence of the prior weight loss. Thus, alterations in resting metabolism or fat oxidation (resting or postprandial) do not appear to be the mechanism(s) by which exercise training facilitates maintenance of diet-induced weight loss.
