BACKGROUND
The present study examined the effects of different temperatures of carbohydrate-protein-containing drinks after exercise on the subsequent gastric emptying rate in healthy young men.
METHODS
Twelve healthy young men completed two, 1-day trials in random order. In both trials, the participants completed intermittent cycling exercise for 20 min, consisting of a 120% heart rate peak for 20 s, followed by 25 W for 40 s. Participants consumed 400 mL of carbohydrate-protein-containing drink (0.85 MJ) at 4 °C (EX + 4 °C) or 60 °C (EX + 60 °C) over a 5-min period after exercise. The participants sat on a chair for 2.5 h to measure their gastric emptying rate using the C-sodium acetate breath test. Subjective feelings of gastrointestinal discomfort and appetite were measured using a visual analog scale. Interstitial fluid glucose levels after drinking were measured using a continuous glucose-monitoring device.
RESULTS
The percentage excretion of CO tended to be higher at EX + 60 °C than at EX + 4 °C from the start of the test until 30 min after drink ingestion (5.7 ± 0.5 vs. 6.5 ± 0.4%dose/h for the EX + 4 °C and EX + 60 °C trials, respectively; effect sizes [ES] = 0.277, p = 0.065). The time of maximum CO emissions per hour (Tmax-calc) and the time of half CO emissions per hour (T) did not differ between trials. Subjective gastrointestinal discomfort was lower at EX + 60 °C compared to EX + 4 °C (ES = 0.328, p = 0.041). There were no significant differences in interstitial fluid glucose levels between the different temperatures of carbohydrate-protein-containing drinks after exercise (p = 0.698).
CONCLUSIONS
Consumption of warm carbohydrate-protein-containing drinks after exercise may accelerate gastric emptying in the very early phase and may reduce gastric discomfort.

背景
本研究旨在探讨运动后不同温度的含碳水化合物-蛋白质饮料对健康年轻男性胃排空率的影响。
方法
12 名健康年轻男性以随机顺序完成了两项为期 1 天的试验。在两项试验中，参与者均进行了 20 分钟的间歇性自行车运动，包括以 120%的心率峰值运动 20 秒，随后以 25W 运动 40 秒。运动后，参与者在 5 分钟内饮用 400 毫升含碳水化合物-蛋白质的饮料（0.85MJ），温度分别为 4°C（EX+4°C）或 60°C（EX+60°C）。参与者坐在椅子上 2.5 小时，使用 C-醋酸钠呼吸试验测量胃排空率。使用视觉模拟量表测量胃肠道不适和食欲的主观感受。饮用后，使用连续血糖监测仪测量间质液葡萄糖水平。
结果
从试验开始到摄入饮料后 30 分钟，CO 的排泄百分比在 EX+60°C 时比在 EX+4°C 时趋于更高（EX+4°C 和 EX+60°C 试验分别为 5.7±0.5%和 6.5±0.4%dose/h；效应大小[ES]为 0.277，p=0.065）。每小时 CO 排放最大值的时间（Tmax-calc）和每小时 CO 排放一半的时间（T）在不同试验中没有差异。与 EX+4°C 相比，EX+60°C 时胃肠道不适的主观感受较低（ES=0.328，p=0.041）。运动后不同温度的含碳水化合物-蛋白质饮料之间的间质液葡萄糖水平没有差异（p=0.698）。
结论
运动后饮用温热的含碳水化合物-蛋白质饮料可能会加速胃排空，特别是在早期阶段，并可能减轻胃部不适。
