我们调查了运动强度和地区差异对男孩催汗运动募集模式的影响。6名青春期前男孩（年龄11 ± 1岁）在温和条件（28 °C，40%相对湿度）下以轻度、中度和高运动强度（35%、50%和65%VO2max）骑自行车30分钟。局部出汗率（通风胶囊）和激活的汗腺（淀粉碘技术）在五个身体部位的数量进行了评估，并计算汗腺输出。男孩的反应与在相同条件下测试的9名年轻男子（23 ± 1岁）的反应进行了比较。男孩的前额、胸部、背部和前臂（但不包括大腿）出汗率从轻度增加到中度和高强度（allp≤ 0.005），但不是从中度增加到高度（allp≥ 0.071）。在中等强度和高强度下，男孩的前额出汗率相对较高（p≤ 0.045），大腿出汗率较低（p≤ 0.050）。运动强度依赖性出汗与激活更多的汗腺有关，但不会增加男孩的腺体输出。与男性相比，男孩的出汗率在身体部位不同程度地减弱，同时腺体输出量较低（allp≤ 0.027）。我们的结论是运动强度调节出汗率在男孩通过改变激活的汗腺的数量不均匀的皮肤部位。在较高的运动强度下，汗流模式中与运动相关的差异是明显的。从男孩到年轻男性的每个腺体的腺体输出量的发展可能在调节运动强度和区域差异方面的出汗率方面发挥关键作用。
We investigated the influence of exercise intensities and regional differences in the sudomotor recruitment pattern in boys. Six prepubertal boys (age 11 ± 1 yr) cycled at light, moderate, and high exercise intensity (35%, 50%, and 65% VO2max) for 30 min in a temperate condition (28 °C, 40% relative humidity). Local sweat rate (ventilated capsule) and number of activated sweat glands (starch-iodine technique) at five body sites were assessed and sweat gland output was calculated. Responses in boys were compared with those in nine young men (23 ± 1 yr) tested under identical conditions. The forehead, chest, back, and forearm, but not thigh, sweat rate increased from light to moderate and at high intensities in boys (allp≤ 0.005) but not from moderate to high (allp≥ 0.071). The sweat rate on the forehead was relatively higher (p≤ 0.045) and thigh was lower (p≤ 0.050) than other sites in boys at moderate and high intensities. Exercise intensity-dependent sweating was associated with activating more sweat glands but not increasing glandular output in boys. The sweat rate in boys was attenuated versus men heterogeneously across body sites concurrent to low glandular outputs (allp≤ 0.027). We conclude that exercise intensity modulates the sweat rate in boys by changing the number of activated sweat glands heterogeneously among skin sites. Age-related differences in the sudomotor pattern are evident at higher exercise intensities. Development of glandular output per gland occurring from boys to young men may play a key role in modulating sweat rate with respect to exercise intensity and regional differences.
