To investigate the effects of moderate-intensity aerobic exercise on appetite control parameters, appetite perceptions, and energy intake in sedentary males with obesity.
Eleven males with obesity (body fat percentage 36.5 ± 2.5%, body mass index 35.3 ± 4.2 kg/m, V̇O 29 ± 3.1 mL·kg·min) completed two experimental sessions: (1) no exercise (CTRL) and (2) 60 min of moderate-intensity cycling exercise at 60% V̇O (MICT) in a crossover design. Blood analysis included growth differentiation factor 15 (GDF-15), total ghrelin, peptide tyrosine tyrosine (PYY), total glucagon-like peptide-1 (GLP-1), insulin, and glucose, as well as subjective appetite perceptions were measured in specific intervals. A standard breakfast at 0 h and an ad libitum meal postexercise was provided.
GDF-15 (95% confidence interval [CI]: [2.48-27.28] ng/L, = 0.021) increased immediately following MICT compared to CTRL. However, there were no differences for PYY ( = 0.480, ), total ghrelin ( = 0.646, ), and total GLP-1 ( = 0.451, ) between sessions. Appetite perceptions (95% CI: [(-20.38)-(-6.16)] mm, = 0.001) were suppressed following MICT though energy intake was not different between the sessions (95% CI: [(-1904.9)-928.1] kJ, = 0.480).
Sixty minutes of MICT increased GDF-15 while suppressing appetite perceptions in individuals with obesity. There was no energy compensation postexercise.
探讨中等强度有氧运动对久坐不动的肥胖男性食欲控制参数、食欲感知及能量摄入的影响。
11名肥胖男性（体脂百分比36.5±2.5%，体重指数35.3±4.2kg/m，摄氧量29±3.1mL·kg·min）完成了两个实验阶段：（1）无运动（对照组）和（2）在交叉设计中以60%摄氧量进行60分钟的中等强度骑行运动（MICT）。血液分析包括生长分化因子15（GDF-15）、总胃饥饿素、肽YY（PYY）、总胰高血糖素样肽-1（GLP-1）、胰岛素和葡萄糖，并在特定时间段测量主观食欲感知。在0小时提供标准早餐，并在运动后提供随意餐。
与对照组相比，MICT后GDF-15（95%置信区间[CI]：[2.48 - 27.28]ng/L，P = 0.021）立即升高。然而，各阶段之间PYY（P = 0.480）、总胃饥饿素（P = 0.646）和总GLP-1（P = 0.451）无差异。MICT后食欲感知（95%CI：[(-20.38)-(-6.16)]mm，P = 0.001）受到抑制，尽管各阶段之间能量摄入无差异（95%CI：[(-1904.9)-928.1]kJ，P = 0.480）。
60分钟的MICT可增加肥胖个体的GDF-15，同时抑制食欲感知。运动后没有能量补偿。
