摘要
对近10年来国内外相关的研究结果进行研究与总结,结果发现:1)雌激素对心血管结构和功能有良好的影响,对心肌糖元、肌肉中磷酸肌酸等的恢复有影响,对蛋白质代谢也有直接或间接影响,从而使运动能力受影响;2)雌激素具有抗氧化和保护细胞膜稳定性的作用,对耐力项目运动能力及减少运动损伤的发生有重要意义;3)雌激素不仅对中枢神经系统具有直接作用,还可通过神经内分泌免疫调节网络的平衡,对中枢认知功能产生间接作用。主要结论:雌激素的作用是多途径和多环节的,利用雌激素分泌状态对提高女运动员运动能力,预防运动损伤无疑具有良好的意义。
The phrpose of this paper is to summarize biological effects of estrogen and it's influence on performance.Result:Both endogenous and exogenous estrogens have significant acute and chronic effects upon cardiovascular structure and function as well as cardio-protective effects for heart disease. Specifically,transiently increased blood volume, plasma volume, stroke volume and cardiac output,the level of blood glucose have been reported during the luteal phase and during oral contraceptive consumption as a direct consequence of raised circulating levels of estrogen. No significant changes were observed in maximum serum lactic acid after an anaerobic endurance test. Estrogen might have direct and indirecteffects on protein metabolism. It's also helpful to antioxidant and stability of amphithecium. Conclusion: The effects of Estrogen are multifunctional, which is probably related to higher performance when plasma level of E is higher.
