Complete energy balance measurements were made in exercise-trained (treadmill running) rats subjected to 27 d of exercise detraining. The 20% difference in body-weight that existed at the end of the training period between sedentary and trained rats was negated by detraining. Detrained rats had twice the body-weight gain of their untrained controls. An elevation (12%) in metabolizable energy (ME) intake (relative to body-weight) was observed in detrained rats while their gross energetic efficiency was augmented by 60%. Energy expenditure, excluding the estimated costs of fat and protein storage, was similar for detrained and untrained rats. Complementing the latter was the finding that thermogenesis in brown adipose tissue, a known energy buffering process, was also similar. Elevated ME intake (relative to body-weight) largely contributed to the increased energetic efficiency of detrained rats.
对经过运动训练（跑步机跑步）的大鼠进行了为期27天的运动去训练，并进行了完整的能量平衡测量。在训练期结束时，久坐不动的大鼠和经过训练的大鼠之间存在的20%体重差异，通过去训练而消除。去训练的大鼠体重增加是未训练对照组的两倍。去训练的大鼠可代谢能量（ME）摄入量（相对于体重）升高了12%，而它们的总能量效率提高了60%。排除脂肪和蛋白质储存的估计成本后，去训练的大鼠和未训练的大鼠的能量消耗相似。与此相辅相成的是，已知的能量缓冲过程——棕色脂肪组织中的产热也相似。ME摄入量升高（相对于体重）在很大程度上导致了去训练大鼠能量效率的提高。
