进行了两项研究，以检查冰泥摄入（ICE）和冷水浸泡（CWI）对体温调节和汗液反应的影响，在恒定（研究1）和自行调节（研究2）的运动。在研究1中，11名男性以40-50%的峰值有氧功率骑行60分钟（33.2 +/- 0.3摄氏度，45.9 +/- 0.5%相对湿度，RH）。在研究2中，11名男性在相当于15（33.9 +/- 0.2摄氏度和42.5 +/- 3.9%相对湿度）的自觉劳累（RPE）下骑自行车60分钟。在这两项研究中，每次试验之前都有30分钟的CWI（类似于22摄氏度），ICE或无冷却（CON）。测量直肠温度（T-re）、皮肤温度（T-sk）、热感觉和汗液反应。在研究1中，在运动的前5分钟内，ICE与CON相比降低了T-re-T-sk梯度（p = 0.005），而CWI在运动期间长达20分钟内与CON和ICE相比增加了T-re-T-sk梯度（p
Two studies were conducted to examine the effects of ice slushy ingestion (ICE) and cold water immersion (CWI) on thermoregulatory and sweat responses during constant (study 1) and self-paced (study 2) exercise. In study 1, 11 men cycled at 40-50% of peak aerobic power for 60 min (33.2 +/- 0.3 degrees C, 45.9 +/- 0.5% relative humidity, RH). In study 2, 11 men cycled for 60 min at perceived exertion (RPE) equivalent to 15 (33.9 +/- 0.2 degrees C and 42.5 +/- 3.9% RH). In both studies, each trial was preceded by 30 min of CWI (similar to 22 degrees C), ICE or no cooling (CON). Rectal temperature (T-re), skin temperature (T-sk), thermal sensation, and sweat responses were measured. In study 1, ICE decreased T-re-T-sk gradient versus CON (p = 0.005) during first 5 min of exercise, while CWI increased T-re-T-sk gradient versus CON and ICE for up to 20 min during the exercise (p
