Regional differences in skin temperature (Ts) were determined by infrared radiography in four competitive swimmers of varying body compositions, prior to, after 5 min of immersion in water (Tw) at 23.5 degrees C, and after a 500-m freestyle swim at a training pace. Decreases in skin temperature that correlated with skinfold thickness were seen post-immersion (r = 0.56, p less than 0.05). After swimming, skin temperatures were highest in regions overlying active muscle masses and were independent of skinfold thickness. These regions were the deltoids, trapezius, triceps and biceps brachi, and pectorals. Swimming increased the extent of warmer skin surface areas and gradient Ts-Tw, over which heat loss could occur.
通过红外热成像技术，对四名身体成分各异的竞技游泳运动员在以下三个阶段的皮肤温度（Ts）区域差异进行了测定：浸入23.5摄氏度水（Tw）中5分钟之前、之后，以及以训练速度完成500米自由泳之后。浸入水中后，观察到皮肤温度下降与皮褶厚度相关（r = 0.56，p < 0.05）。游泳后，活跃肌肉群上方区域的皮肤温度最高，且与皮褶厚度无关。这些区域包括三角肌、斜方肌、肱三头肌、肱二头肌和胸肌。游泳增加了较温暖皮肤表面积的范围以及Ts-Tw梯度，在此范围内可能发生热量散失。
