This preliminarily study was made to examine the differences in sweat excretions from human eccrine and apocrine sweat glands in dynamic exercise and heat conditions. Sweat samples were collected from six young males while they were either running on a treadmill or sitting in a sauna cabinet. Sweat samples of at least 5 mL from the eccrine (upperback) and apocrine (armpit) sweat glands were collected during a 20min running (or inactive overheating) period. The samples were then analyzed for urea, uric acid, and electrolyte (Na, Cl, and K) excretions. The results from a twoway repeatedmeasures analysis of variance (ANOVA) revealed that the secretions of urea and K were significantly higher during running than during inactive overheating for both glands, as were Na secretions for the apocrine glands (all P < 0.05). Under the same sweating conditions, urea and K excretions from the apocrine glands were also higher than those from the eccrine glands (all P < 0.05). Significant differences were observed between the Na secretions of the apocrine and eccrine glands under the running condition. The effects of various sweating methods and sweat glands on Cl secretions were nonsignificant, and little uric acid was excreted. A higher urea excretion level during running rather than in hot conditions could be attributed to an elevated metabolic rate.
本初步研究旨在探讨在动态运动和热环境下，人体大汗腺和小汗腺的汗液分泌差异。从 6 名年轻男性收集汗液样本，他们在跑步机上跑步或坐在桑拿室内。在 20 分钟的跑步（或不活动过热）期间，从小汗腺（上背部）和大汗腺（腋窝）收集至少 5 毫升的汗液样本。然后分析样本中的尿素、尿酸和电解质（Na、Cl 和 K）的排泄量。双向重复测量方差分析（ANOVA）的结果表明，对于两种腺体，尿素和 K 的分泌在跑步时明显高于不活动过热时，Na 的分泌在大汗腺中也是如此（均 P < 0.05）。在相同的出汗条件下，大汗腺的尿素和 K 排泄也高于小汗腺（均 P < 0.05）。在跑步条件下，大汗腺和小汗腺的 Na 分泌存在显著差异。各种出汗方式和汗腺对 Cl 分泌的影响无显著性差异，尿酸排泄量较少。在跑步过程中而不是在炎热条件下，尿素排泄水平升高可能归因于代谢率升高。
