背景:有关训练中网球运动员外周发汗机制的研究相对较少。本研究旨在比较受过训练和未经训练的网球运动员的发汗能力。方法:35名健康男性志愿者参与研究,其中15名未受过训练,另外20名受过训练的网球运动员(拥有国内排名)。受试者在人工恒温室(温度25℃±0.5℃,相对湿度60%±3%,称为“积极保温”)以60%VO_(2max)强度跑步30 min。用电容通风湿度计小盒与淀粉碘化钾试纸获得发汗数据(包括局部发汗开始时间、局部出汗量、汗腺激活情况、单个腺汗出汗量、全身出汗量)。用鼓膜和皮肤温度计算身体平均温度。结果:网球运动员局部发汗的开始时间较短(p<0.001),主动保温后,受过训练的网球运动员躯干及四肢的局部出汗量、汗腺激活、单个汗腺出汗量、全身出汗量均明显高于对照组(p<0.001),鼓膜和皮肤平均温度低于对照组队员(p<0.05)。结论:在积极保温过程中网球运动员的汗腺控制功能得到提高。
Background: There are relatively few studies on the mechanism of perspiration in tennis players during training. The aim of this study was to compare the sweating ability of trained and untrained tennis players. METHODS: Thirty-five healthy male volunteers participated in the study, 15 of whom were untrained and another 20 were trained tennis players (with domestic rankings). Subjects ran for 30 min at a 60% VO 2max intensity in a manual thermostatic chamber (temperature 25 ° C ± 0.5 ° C, relative humidity 60% ± 3%, referred to as “Active Insulation”). Sweat data (including local sweating onset time, local sweating volume, sweat gland activation, sweat volume of a single gland sweat, total body sweating volume) were obtained using a capacitive humidity hygrometer cassette and a starch potassium iodide test strip. Calculate the average body temperature using the tympanic membrane and skin temperature. RESULTS: Tennis athletes had a slightly shorter onset of local sweating (p <0.001). After active warm-keeping, the sweat volume, sweat gland activation, sweat volume of individual sweat glands, and sweat volume of trained tennis players were significantly higher on the trunk and extremities Higher than the control group (p <0.001), the average tympanic membrane and skin temperature was lower than the control group (p <0.05). Conclusion: The sweat gland control function of tennis players is improved during active heat preservation.
