背景：在高温的室外，来自太阳的高太阳辐射可能会损害运动能力。本研究旨在比较不同太阳辐射水平对运动能力的影响，并评估高温下皮肤温度的反应。方法：7名男性参与者在炎热的室外环境（大约33-35摄氏度，40-50%相对湿度）下，在晴朗的天空下（高太阳辐射试验：1062 +/- 50 W/m2）和厚云层下（低太阳辐射试验：438 +/- 52 W/m2），以最大摄氧量的60%进行自行车运动，直到自愿耗尽。结果：高太阳辐射组受试者的疲劳时间（32.0 +/- 12.4 min）短于低太阳辐射组（39.2 +/- 18.0 min: P=0.045）。高太阳辐射组的平均皮肤温度显著高于低太阳辐射组(P
BACKGROUND: High solar radiation from the sun in the heat outdoor may be impaired exercise capacity. This study aimed to compare the effects of different levels of solar radiation on exercise capacity and evaluate skin temperature responses in the heat. METHODS: Seven male participants performed cycling exercise at 60% of their maximal oxygen uptake until volitional exhaustion in hot outdoor environments (approximately 33-35 degrees C, 40-50% relative humidity) under both clear sky (high solar radiation trial: 1062 +/- 50 W/m2) and under thick clouds (low solar radiation trial: 438 +/- 52 W/m2). RESULTS: The time to exhaustion of the participants was shorter in the high solar radiation trial (32.0 +/- 12.4 min) than in the low solar radiation trial (39.2 +/- 18.0 min: P=0.045). Mean skin temperature was significantly higher in the high solar radiation trial than that in the low solar radiation trial (P
