The present study examined the effects of different temperatures of protein-containing drink after exercise on subsequent gastric motility and energy intake in healthy young men. Twelve healthy young men completed three, 1-d trials in a random order. In all trials, the subjects ran on a treadmill for 30 min at 80% of maximum heart rate. In exercise + cold drink (2°C) and exercise + hot drink (60°C) trials, the subjects consumed 300 ml of protein-containing drink (0·34 MJ) at 2°C or 60°C over a 5-min period after exercise. In the exercise (i.e. no preload) trial, the subjects sat on a chair for 5 min after exercise. Then, the subjects sat on a chair for 30 min to measure their gastric motility with an ultrasound imaging system in all trials. Thereafter, the subjects consumed a test meal until they felt comfortably full. Energy intake in the exercise + hot drink trial was 14 % and 15 % higher than the exercise (P = 0·046, 95% CI 4·010, 482·538) trial and exercise + cold drink (P = 0·001, 95% CI 160·089, 517·111) trial, respectively. The frequency of the gastric contractions in the exercise + hot drink trial was higher than the exercise (P = 0·023) trial and exercise + cold drink (P = 0·007) trial. The total frequency of gastric contractions was positively related to energy intake (r = 0·386, P = 0·022). These findings demonstrate that consuming protein-containing drink after exercise at 60°C increases energy intake and that this increase may be related to the modulation of the gastric motility.
本研究旨在探讨运动后不同温度的含蛋白饮料对健康年轻男性随后胃动力和能量摄入的影响。12 名健康年轻男性以随机顺序完成了三项为期 1 天的试验。在所有试验中，受试者在跑步机上以 80%的最大心率跑步 30 分钟。在运动+冷饮料（2°C）和运动+热饮料（60°C）试验中，受试者在运动后 5 分钟内饮用 300 毫升含蛋白饮料（0.34 兆焦耳），温度分别为 2°C 或 60°C。在运动（即无预负荷）试验中，受试者在运动后坐在椅子上 5 分钟。然后，受试者坐在椅子上 30 分钟，在所有试验中使用超声成像系统测量胃动力。此后，受试者食用测试餐，直到感到舒适饱足为止。运动+热饮料试验的能量摄入比运动（P = 0.046，95%CI 4.010，482.538）和运动+冷饮料（P = 0.001，95%CI 160.089，517.111）试验分别高 14%和 15%。运动+热饮料试验的胃收缩频率高于运动（P = 0.023）和运动+冷饮料（P = 0.007）试验。胃收缩总频率与能量摄入呈正相关（r = 0.386，P = 0.022）。这些发现表明，运动后饮用 60°C 的含蛋白饮料会增加能量摄入，而这种增加可能与胃动力的调节有关。
