本研究的目的是比较两支世界级车队（均由 9 名顶级男性自行车运动员组成）在真实运动情况（1998 年 Nuelta a Espana”，为期 3 周的多阶段国际自行车比赛）中血浆总睾酮 (T)、皮质醇 (C)、黄体生成素 (LH)、卵泡刺激素 (FSH) 和催乳素 (P) 的激素变化。静脉血样本比赛前一天（S0）、比赛后 1 周（S1）、比赛后 2 周（S2）和比赛结束时（S3），前一个月比赛天数较多的球队的 S0 T 水平明显较低。尽管各队之间的 S0 T 水平存在差异，但比赛期间的基础 T 水平明显降低（p < 0.05）。 S0 和 S1 之间以及 S1 和 S2 之间没有显着降低，但在 S2 和 S3 之间，除 S2 和 S3 之间的 P 浓度没有显着增加外，团队之间以及任何研究随访时间中的 LH 和 FSH 浓度没有初始差异。我们得出的结论是，在职业顶级运动员中，S0 T 值取决于前一个月的比赛天数。在长时间的自行车比赛中，两队C的绝对S0值均下降。
The aim of this study was to compare hormonal changes in plasma total testosterone (T), cortisol (C), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and prolactin (P) in two world-class teams, both consisting of 9 top male pro-cyclists, during a real sports situation (the 1998 Nuelta a Espana", a 3-week multi-stage international cycling competition). Venous blood samples were taken the day before the race (S0), after 1 week (S1), after 2 weeks (S2) and at the end of the race (S3). The S0 T level was significantly lower in the team with more racing days in the previous month. There was a significant basal T decrease (p < 0.05) during the race in comparison with the initial value, in spite of the difference in S0 T level between teams. However, there was no difference between teams in the mean decrease in T level. C decreased significantly between S0 and S1 and between S1 and S2, but not between S2 and S3. There were no differences in P concentration between teams or throughout the study, except for a significant increase between S2 and S3. There were no initial differences in LH nor FSH concentration between the teams, nor at any of the study follow-up times. We conclude that in professional top-level athletes S0 T values depend on the number of competition days of the previous month. We observed a similar decrease in the T levels in both teams, independent of the absolute S0 values. In both teams C decreased during long-lasting cycling competition.
