我们的目的是调查大范围的日常体力活动(PA)水平对能量平衡(EB)、能量摄入量(EI)和食欲的影响。9名青年男性在一个代谢室中按随机顺序完成三种不同的PA水平：(1)不运动(低PA)；(2)25min步行7次(Mid-PA)；(3)在24小时内跑25分钟7次(High-PA)。间歇运动(运动25min，休息35min)，上午3次，下午4次。运动强度中PA和高PA分别为21.6%和53.7%VO2峰值。参与者被提供了三顿标准化的晚餐和一份自助餐。用24 h能量消耗(EE)减去24 h Ei计算24 h EB。低PA、中PA和高PA的24 h EES分别为1907+/-200、2232+/-240和3224+/-426千卡，三种情况下的EES有显著差异(低PA与中PA、低PA与高PA、中PA与高PA分别为P<；0.01)。低PA、中PA和高PA天数的24 h EIS分别为3232+/-528、2991+/-617和3337+/-684kcal，与PA水平无关(p=0.115)。24 h EBS分别为1324+/-441kcal(低PA)、759+/-543kcal(中PA)和113+/-430kcal(高PA)，低PA与中PA、低PA与高PA之间有显著差异(p=0.0496)。
We aimed to investigate the effects of a wide range of daily physical activity (PA) levels on energy balance (EB), energy intake (EI), and appetite. Nine young men completed three different PA levels in a metabolic chamber in a random order: (1) no exercise (Low-PA); (2) 25 min walking seven times (Mid-PA); and (3) 25 min running seven times (High-PA) within a 24 h period. Interval exercise (25 min exercise and 35 min rest) was performed three times in the morning and four times in the afternoon. The exercise intensities were 21.6% and 53.7% VO2 peak for the Mid-PA and High-PA days, respectively. Participants were served three standardized meals and a buffet for dinner. The 24 h EB was calculated as 24 h energy expenditure (EE) minus 24 h EI. The 24 h EEs for the Low-PA, Mid-PA, and High-PA days were 1907 +/- 200, 2232 +/- 240, and 3224 +/- 426 kcal, respectively, with significant differences observed among the three conditions (p < 0.01 for Low-PA vs. Mid-PA, Low-PA vs. High-PA, and Mid-PA vs. High-PA, respectively). The 24 h EIs for the Low-PA, Mid-PA, and High-PA days were 3232 +/- 528, 2991 +/- 617, and 3337 +/- 684 kcal, and were unaffected by PA levels (p = 0.115). The 24 h EBs were 1324 +/- 441 kcal (Low-PA), 759 +/- 543 kcal (Mid-PA), and 113 +/- 430 kcal (High-PA), with significant differences observed between Low-PA vs. Mid-PA (p = 0.0496), Low-PA vs. High-PA (p
