为了确定运动相关因素对食物摄入量的影响，五名非肥胖女性（平均±标准误，理想体重百分比，97±5）被住院作为代谢实验的一部分。将过量的混合食物放在盘子上提供给受试者。他们用这些东西自己吃，自由地吃。通过在上菜之前和之后称重拼盘来秘密估计摄入量。通过每日活动日记和记录的所有活动的间接热量测定来监测支出。经过五天的评估阶段后，每位受试者接受了三个为期 19 天的治疗期，其中体力活动有所调整。轻度运动期间每日总支出增加至静坐治疗的 114 ± 4%，中等运动期间则增加至 129 ± 3%。运动期间相应的自愿摄入量为久坐治疗时的 117 ± 5% 和 122 ± 6%。虽然中度运动（平均 772 ± 40 kcal/d）高于轻度运动（378 ± 63 kcal/d），但两者增加的摄入水平相当。然而，久坐时的能量平衡为 10 ± 71 kcal/d，轻度治疗的能量平衡为 64 ± 43 kcal/d，中度治疗的能量平衡为 -116 ± 92 kcal/d，但没有不同。因此，在允许在不活动期间维持自愿平衡能量状态的范例中，发生对运动的补偿性摄入反应。肥胖女性的摄入量与体力活动消耗的能量不匹配，而非肥胖女性则表现出贪食反应。
To determine the effect of exercise-related factors on food intake, five nonobese women (mean ± SEM of the percent of desirable body weight, 97 ± 5) were hospitalized as part of a metabolic experiment. Excess amounts of a mixed food diet were provided on platters to the subjects. They served themselves from these and ate freely. Intake was estimated covertly by weighing the platters before and after serving. Expenditure was monitored with daily activity diaries and indirect calorimetry determinations of all the activities recorded. After a five-day evaluation phase, each subject underwent three 19-day treatment periods in which physical activity was modified. Total daily expenditure was increased to 114 ± 4% of the sedentary treatment for a mild exercise period and 129 ± 3% for a moderate period. Corresponding voluntary intakes during exercise were 117 ± 5% and 122 ± 6% of sedentary treatment. Although moderate exercise (mean 772 ± 40 kcal/d) was greater than mild (378 ± 63 kcal/d), the increased intake levels of the two were comparable. However, the resulting energy balances of 10 ± 71 kcal/d for sedentary, 64 ± 43 kcal/d for mild and −116 ± 92 kcal/d for moderate treatments were not different. Therefore, in a paradigm which permits maintenance of a voluntary balanced energy state during an inactive period, compensatory intake responses to exercise occur. Unlike obese women who do not match their intakes to energy expended as physical activity, nonobese women demonstrate hyperphagic responses.
