Seven male volunteers were divided into two groups based on body morphology and mass. The large body mass (LM) group (n = 4) was 21.2 kg heavier and 0.32 m2.kg-1 smaller in surface area-to-mass ratio (P < 0.05) than the small body mass (SM) group (n = 3). Both groups were similar in total body fat and regional skinfold thicknesses. All subjects were immersed to the first thoracic vertebrae for 120 min in stirred water at 18 degrees C. Overall, tissue insulation was similar (P > 0.05) between the SM and LM groups across time. Perceptual ratings of thermal sensation increased (P < 0.05) across time. Therefore, as cold water immersion progressed, tissue insulation was similar and thermal sensation increased (P < 0.05) in males matched for subcutaneous fat and total fat but differing in body mass and morphology.
七名男性志愿者根据身体形态和体重被分为两组。大体重（LM）组（n = 4）比小体重（SM）组（n = 3）重21.2千克，体表面积与体重之比小0.32平方米·千克⁻¹（P < 0.05）。两组在全身脂肪和局部皮褶厚度方面相似。所有受试者均在18摄氏度的搅拌水中浸泡至第一胸椎水平，持续120分钟。总体而言，SM组和LM组在整个时间段内的组织隔热情况相似（P > 0.05）。热感觉的感知评分随时间增加（P < 0.05）。因此，随着冷水浸泡的进行，在皮下脂肪和总脂肪匹配但体重和形态不同的男性中，组织隔热情况相似，热感觉增加（P < 0.05）。
