| 摘 要： | 目的:探讨补充橘皮素对短跑运动员冬训期间血清睾酮、皮质醇水平的影响。方法:将24名短跑运动员配对、随机分为试验组和对照组。冬训期间,试验组补充橘皮素补剂(含橘皮素200 mg),对照组补充安慰剂,为期4周。分别在每周第一天(T1、T2、T3、T4)及干预结束次日(T5)采集血液样本,检测血清睾酮、皮质醇、超氧化物歧化酶(SOD)、促肾上腺皮质激素(ACTH)等指标,并在干预开始和结束时测试身体成分。结果:干预4周后,①对照组的血清皮质醇水平上升,血清睾酮和SOD活性水平显著下降(P＜0.05);②试验组的血清皮质醇(P＜0.05)和ACTH(P＜0.01)均显著下降,血清睾酮维持稳定,SOD活性水平小幅上升;③试验组和对照组的肌肉量均有增加,但前者的增加量显著大于后者。结论:补充4周橘皮素能减少冬训期间高强度运动引起的机体氧化应激反应,维持机体血清睾酮水平稳定,抑制皮质醇过度分泌,促进肌肉合成。

| Abstract: | Objective: To evaluate the regulation efficacy of oral tangeretin on testosterone and cortisol in sprinters at winter training season. Methods: Twenty-four sprinters were paired and randomly divided into experimental group (EG) and control group (CG). During winter training season, EG were treated with 200 mg tangeretin by oral, and CG were treated with placebo for 4 weeks. Blood samples were collected on the first day of each week (T1, T2, T3, T4) and after the intervention (T5) to detect serum levels of testosterone, cortisol, superoxide dismutase (SOD), and adrenocorticotropic hormone (ACTH). The body composition was tested at T1 and T5. Results: After 4 weeks, ①the serum cortisol level of CG was increased, and the serum levels of testosterone and SOD were decreased significantly (P＜0.05). ②In EG, the serum levels of cortisoland ACTH were decreased significantly (P＜0.05, P＜ 0.01), while the serum testosterone level was remained stable, and the level of SOD was increased slightly. ③The muscle mass of EG and CG were increases, but that of EG was increased higher than that of CG. Conclusion: Tangeretin reduces the oxidative stress response that caused by high-intensity exercise during winter training, which maintain the serum testosterone level and inhibit cortisol excessive secretion and promote muscle synthesis. |
