The hyperthermic response to exercise in a warm (30 degrees C), humid (80% relative humidity) environment was obtained for 23 prepubertal males. After the initial increase of core temperatures (tympanic and rectal) to elevated set points, further hyperthermia was minimal and was unrelated to any physique variable except for the case of endomorphy, which was weakly correlated with hyperthermia at the rectal site. This result for boys is attributed to the combination of small body size (relative to adults) and absence of pronounced, age-dependent muscular development as evidenced by low rating and small variation of the mesomorphy component of somatotype. Both of these factors were associated with a high surface area to weight ratio compared to adults, which facilitated heat loss. It is concluded that prepubertal males thermoregulate efficiently during moderate exercise in a warm, humid environment. Other than cases of obesity, variation in physique is not an important consideration for assessing the risk of heat strain.
对23名青春期前男性在温暖（30摄氏度）、潮湿（相对湿度80%）环境中运动时的热反应进行了研究。在核心体温（鼓膜和直肠温度）最初升高到设定的较高水平后，进一步的体温过高情况很轻微，且与任何体格变量均无关联，但对于内胚层体型的情况除外，内胚层体型与直肠部位的体温过高呈弱相关。男孩的这一结果归因于体型较小（相对于成年人）以及缺乏明显的、与年龄相关的肌肉发育，这可由体型中中胚层成分的低评分和小变化得到证明。与成年人相比，这两个因素都与较高的表面积与体重比相关，这有利于热量散失。得出的结论是，青春期前男性在温暖、潮湿环境中进行适度运动时能有效地进行体温调节。除肥胖情况外，体格差异并非评估热应激风险的重要考虑因素。
