本研究的目的是确定反复热应激和冷水浸泡对中等和高水平体力活动（PA）的年轻成年男性内分泌系统的影响。研究对象为30名19-26岁的男性（平均年龄：22.67 ± 2.02），他们参加了四次桑拿浴，每次12分钟（温度：90 - 91°C;相对湿度：14- 16%）。每次桑拿浴后，受试者在冷水（10 - 11°C）中浸泡1分钟，然后进行6分钟的降温休息。测量桑拿浴前后的睾酮（TES）、皮质醇（COR）、硫酸脱氢表雄酮（DHEA-S）和催乳素（PRL）水平。参与者的PA水平使用国际体力活动问卷进行评估。在72分钟的桑拿治疗期间，血清COR水平从13.61 μg/ml显著降低（p <0.001）至9.67 μg/ml。其余激素的浓度没有显著变化（p > 0.05）：TES从4.04 ng/ml增加到4.24 ng/ml，DHEA-S从357.5 μ g/ml减少到356.82 μg/ml，PRL从14.50 ng/ml减少到13.71 ng/ml。桑拿后，在基线COR水平较高的男性中观察到COR浓度的较大下降，而在基线COR值非常低的参与者中仅观察到轻微下降（r =-0.673，p <.001）。芬兰桑拿浴的重复使用会导致COR浓度的显著下降，但不会导致TES，DHEA-S或PRL水平的显著变化。在桑拿浴前后，PA水平较高的男性体内睾酮浓度较高。
The aim of the study was to determine the effect of repeated hot thermal stress and cold water immersion on the endocrine system of young adult men with moderate and high levels of physical activity (PA). The research was conducted on 30 men aged 19–26 years (mean: 22.67 ± 2.02) who attended four sauna sessions of 12 min each (temperature: 90−91°C; relative humidity: 14–16 %). Each sauna session was followed by a 6-min cool-down break during which the participants were immersed in cold water (10−11°C) for 1 min. Testosterone (TES), cortisol (COR), dehydroepiandrosterone sulfate (DHEA-S), and prolactin (PRL) levels were measured before and after the sauna bath. The participants’ PA levels were evaluated using the International Physical Activity Questionnaire. Serum COR levels decreased significantly (p < .001) from 13.61 to 9.67 µg/ml during 72 min of sauna treatment. No significant changes (p >.05) were noted in the concentrations of the remaining hormones: TES increased from 4.04 to 4.24 ng/ml, DHEA-S decreased from 357.5 to 356.82 µg/ml, and PRL decreased from 14.50 to 13.71 ng/ml. After sauna, a greater decrease in COR concentrations was observed in males with higher baseline COR levels, whereas only a minor decrease was noted in participants with very low baseline COR values (r =−0.673, p <.001). Repeated use of Finnish sauna induces a significant decrease in COR concentrations, but does not cause significant changes in TES, DHEA-S, or PRL levels. Testosterone concentrations were higher in men characterized by higher levels of PA, both before and after the sauna bath.
