The aim of this study was to evaluate the effects of skimmed milk as a recovery drink following moderate-vigorous cycling exercise on subsequent appetite and energy intake in healthy, female recreational exercisers. Utilising a randomised cross-over design, nine female recreational exercisers (19.7 ± 1.3 years) completed a V̇O2peak test followed by two main exercise trials. The main trials were conducted following a standardised breakfast. Following 30 min of moderate-vigorous exercise (65% V̇O2peak), either 600 mL of skimmed milk or 600 mL of orange drink (475 mL orange juice from concentrate, 125 mL water), which were isoenergetic (0.88 MJ), were ingested, followed 60 min later with an ad libitum pasta meal. Absolute energy intake was reduced 25.2% ± 16.6% after consuming milk compared to the orange drink (2.39 ± 0.70 vs. 3.20 ± 0.84 MJ, respectively; p = 0.001). Relative energy intake (in relation to the energy content of the recovery drinks and energy expenditure) was significantly lower after milk consumption compared to the orange drink (1.49 ± 0.72 vs. 2.33 ± 0.90 MJ, respectively; p = 0.005). There were no differences in AUC (× 1 h) subjective appetite parameters (hunger, fullness and desire to eat) between trials. The consumption of skimmed milk following 30 min of moderate-vigorous cycling exercise reduces subsequent energy intake in female recreational exercisers.
本研究旨在评估脱脂牛奶作为中等强度到高强度骑行运动后的恢复饮品,对健康女性休闲锻炼者后续食欲和能量摄入的影响。采用随机交叉设计,9名女性休闲锻炼者(19.7±1.3岁)完成了最大摄氧量测试,随后进行了两项主要运动试验。主要试验在标准化早餐后进行。在进行30分钟的中等强度到高强度运动(65%最大摄氧量)后,摄入600毫升脱脂牛奶或600毫升橙汁饮料(475毫升浓缩橙汁,125毫升水),二者能量相等(0.88兆焦),60分钟后随意食用意大利面餐。与饮用橙汁饮料相比,饮用牛奶后绝对能量摄入量降低了25.2%±16.6%(分别为2.39±0.70兆焦和3.20±0.84兆焦;p = 0.001)。与饮用橙汁饮料相比,饮用牛奶后相对能量摄入量(相对于恢复饮品的能量含量和能量消耗)显著降低(分别为1.49±0.72兆焦和2.33±0.90兆焦;p = 0.005)。各试验间AUC(×1小时)主观食欲参数(饥饿感、饱腹感和进食欲望)无差异。中等强度到高强度骑行运动30分钟后饮用脱脂牛奶可降低女性休闲锻炼者后续的能量摄入。
