1. 在三项实验中，测量了 10 名女性在进食提供 230–1200 kcal (0.96–5.02 MJ) 的膳食后的氧气利用率。 2.在第一个实验中，四名受试者消耗了每日摄入量的九分之一、三分之一或二分之一，并测量餐后3小时的耗氧量。该反应与膳食量无关。 3.第二次实验严格控制静息条件。每位女性在床上躺 5-7 小时，同时测量为两名体重较轻的受试者提供 600 或 900 kcal（2.51 或 3.77 MJ）的膳食效果，以及为两名较重的受试者提供 800 或 1200 kcal（3.35 或 5.02 MJ）的膳食效果。每个受试者在吃更多的餐后，能量消耗的增加更大。大餐前后两次 30 分钟的散步的影响可以忽略不计。 4. 在第三个实验中，测量了 5 名消耗 900 kcal (3.77 MJ) 热量的女性的运动效果（a）随后休息 5 小时，（b）前后进行运动（在跑步机上进行两次 30 分钟的步行）。餐后 90 分钟内的能量增量相当于 (a) 至每小时 15 kcal (63 kJ) 和 (b) 至每小时 16 kcal (67 kJ)，而运动但不进食后的反应则微不足道。
1. The oxygen utilization of ten women was measured after consuming meals supplying 230–1200 kcal (0.96–5.02 MJ) in three experiments. 2. In the first experiment four subjects consumed one-ninth, one-third or one-half of the daily allowance and the oxygen consumption was measured for 3 h after the meal. The response was unrelated to the size of the meal. 3. Resting conditions were rigidly controlled in the second experiment. Each woman reclined on a bed for 5–7 h while the effect of a meal providing 600 or 900 kcal (2.51 or 3.77 MJ) for the two lighter subjects and 800 or 1200 kcal (3.35 or 5.02 MJ) for two heavier subjects was measured. A greater increment in energy expenditure was obtained after the larger meal for each subject. The effect of two 30 min walks before and after the large meal was negligible. 4. In a third experiment the effect of exercise was measured with five women consuming 900 kcal (3.77 MJ) (a) followed by 5 h rest and (b) preceded and followed by exercise (two 30 min walks on a treadmill). The energy increment during 90 min after the meal was equivalent in (a) to 15 kcal (63 kJ) per h and in (b) to 16 kcal (67 kJ) per h, whereas the response following exercise but without food was insignificant.
