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, â the serum cortisol level of CG was increased, and the serum levels of testosterone and SOD were decreased significantly (Pï¼0.05). â¡In EG, the serum levels of cortisoland ACTH were decreased significantly (Pï¼0.05, Pï¼ 0.01), while the serum testosterone level was remained stable, and the level of SOD was increased slightly. â¢The 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.Palavras-chave
