This study aimed to determine if energy intake and appetite regulation differ in response to an acute bout of resistance exercise (REx) versus aerobic exercise (AEx).
Physically inactive adults (n = 24, 35% ± 2% body fat, 50% female) completed three conditions: AEx (walking at 65%-70% heart rate max for 45 min), REx (1 set to failure of 12 exercises), and sedentary control (SED). Each condition was initiated in the postprandial state (35 min after breakfast). Appetite (visual analog scale for hunger, satiety, and prospective food consumption) and hormones (ghrelin, peptide YY (PYY), and glucagon-like peptide-1 (GLP-1)) were measured before and 30, 90, 120, 150, and 180 min after a standardized breakfast. Area under the curve was calculated using the trapezoid method. Ad libitum energy intake was evaluated at a lunch meal after the 180-min measurements.
No differences in ad libitum energy intake (REx, 991 ± 68; AEx, 937 ± 65; SED, 944 ± 76 kcal; P = 0.50) or appetite ratings (all, P > 0.05) were detected. The area under the curve for ghrelin, PYY, and GLP-1 were all lower after REx versus AEx (ghrelin: 130,737 ± 4928 for REx; 143,708 ± 7500 for AEx (P = 0.006); PYY: 20,540 ± 1177 for REx, 23,812 ± 1592 for AEx (P = 0.001); and GLP-1: 1314 ± 93 for REx, 1615 ± 110 for AEx (P = 0.013)). Neither exercise condition significantly differed from SED.
Acute REx lowers both orexigenic (ghrelin) and anorectic (PYY and GLP-1) gut peptides compared with acute AEx. Ad libitum energy intake did not increase compared with SED in either exercise condition, indicating both exercise modalities have appetite and energy intake suppressing effects. Future work is needed to determine if exercise of differing modalities influences chronic appetite regulation.
本研究旨在确定在急性抗阻运动（REx）与有氧运动（AEx）后，能量摄入和食欲调节是否存在差异。
24 名身体活动不足的成年人（35%±2%体脂，50%女性）完成了三种条件：AEx（以 65%-70%最大心率行走 45 分钟）、REx（1 组至 12 个运动的失败）和久坐对照（SED）。每种条件均在餐后状态下开始（早餐后 35 分钟）。在早餐后 30、90、120、150 和 180 分钟测量食欲（饥饿、饱腹感和预期食物消耗的视觉模拟量表）和激素（ghrelin、肽 YY（PYY）和胰高血糖素样肽-1（GLP-1））。使用梯形法计算曲线下面积。在 180 分钟测量后，在午餐时评估随意能量摄入。
随意能量摄入（REx，991±68；AEx，937±65；SED，944±76 kcal；P=0.50）或食欲评分（均，P>0.05）无差异。REx 后 ghrelin、PYY 和 GLP-1 的曲线下面积均低于 AEx（ghrelin：REx 为 130,737±4928；AEx 为 143,708±7500（P=0.006）；PYY：REx 为 20,540±1177，AEx 为 23,812±1592（P=0.001）；GLP-1：REx 为 1314±93，AEx 为 1615±110（P=0.013））。两种运动条件与 SED 均无显著差异。
急性 REx 降低了食欲肽（ghrelin）和厌食肽（PYY 和 GLP-1），与急性 AEx 相比。与 SED 相比，两种运动条件下的随意能量摄入均未增加，表明两种运动方式均具有抑制食欲和能量摄入的作用。需要进一步研究以确定不同运动方式是否会影响慢性食欲调节。
