关于运动后摄入冷饮的信息有限。我们研究了在炎热的工作-休息周期中，在4摄氏度（冷）或28摄氏度（暖）的温度调节作用。在两个不同的场合，8名健康男性在跑步机上以5.5km/h的速度以7.5%的梯度行走2个周期（工作45 min，休息15 min）。在每个休息期间，消耗两份400 mL 4 ℃或28 ℃的普通水。测量直肠温度（T（re））、皮肤温度（T（sk））、心率和主观评分。在最后一个工作-休息周期结束时，饮用冷饮（0.5 +/- 0.2摄氏度）后T（re）的平均下降幅度大于饮用温饮（0.3 +/- 0.2摄氏度; P
There is limited information on the ingestion of cold drinks after exercise. We investigated the thermoregulatory effects of ingesting drinks at 4 degrees C (COLD) or 28 degrees C (WARM) during work-rest cycles in the heat. On 2 separate occasions, 8 healthy males walked on the treadmill for 2 cycles (45min work; 15min rest) at 5.5km/h with 7.5% gradient. Two aliquots of 400mL of plain water at either 4 degrees C or 28 degrees C were consumed during each rest period. Rectal temperature (T (re) ), skin temperature (T (sk)), heart rate and subjective ratings were measured. Mean decrease in T (re) at the end of the final work-rest cycle was greater after the ingestion of COLD drinks (0.5 +/- 0.2 degrees C) than WARM drinks (0.3 +/- 0.2 degrees C; P
