在4周的时间里，40名肥胖受试者（体重指数30-45 W/H2）在代谢病房接受单独300千卡混合饮食或结合自行车测力器运动训练的治疗。运动对体重的影响较小，脂肪减少1.7公斤（预期减少4.0公斤）。饮食可改善高胰岛素血症，饮食加运动可使高胰岛素血症正常化；在c肽水平上也观察到类似的效果。两组血浆肾上腺素和去甲肾上腺素浓度均下降。在最大工作时，运动组的去甲肾上腺素水平更高。两种方案的受试者在休息和运动时游离脂肪酸和游离甘油都有所增加，运动组的差异更为明显。在耐力运动中，低呼吸商证实了脂肪氧化的增强。由于体能训练，工作能力增加，血压显著降低。结论是，运动训练加上低热量饮食可以降低体重和体脂，尽管程度低于预期。在运动期间和之后，脂肪的动员和氧化得到加强，但这些影响可能在休息时被抵消。另一方面，饮食引起的身体机能下降被过度补偿了。
During 4 weeks, 40 obese subjects (body mass index 30-45 W/H2) were treated with a 300-kcal mixed diet alone or in combination with exercise training on a bicycle ergometer in a metabolic ward. Exercise had a minor effect on body weight, reflected by an additional fat loss of 1.7 kg (expected loss: 4.0 kg). Hyperinsulinemia was improved by diet and normalized by diet combined with exercise; a similar effect was observed regarding C-peptide levels. Plasma concentrations of epinephrine and norepinephrine decreased in both groups. At maximal work, norepinephrine levels were higher in the group with exercise. Free fatty acids and free glycerol increased at rest as well as during exercise in subjects on both regimens, the difference being more pronounced in the exercise group. Enhanced oxidation of fat was substantiated by lower respiratory quotients during endurance exercise. Working capacity increased and blood pressure decreased considerably as a consequence of physical training. It is concluded that exercise training in addition to a hypocaloric diet lowers body weight and body fat, although to a lower degree than expected. During and following bouts of exercise, fat mobilization and oxidation is enhanced, but these effects are probably counteracted at rest. On the other hand, the diet-induced deterioration of physical performance is overcompensated.
