摘要
探讨不同性别运动员在进行大、小运动量训练前、后及恢复期的血、尿性激素水平。发现男运动员在大、小运动量训练后及恢复期血中睾酮 (T)、游离睾酮 (FT)和 17 羟孕酮 (17 OHP)均无明显变化 (P >0 .0 5 ) ,尿中上述激素于运动后明显增加 (P <0 .0 5 ) ,恢复期明显降低 (P <0 .0 5 )。女运动员在小运动量后除 17 OHP明显增加 (P <0 .0 5 )外 ,T ,FT无明显变化 ,尿中激素在运动后和恢复期均明显降低 (P <0 .0 5 ) ;在大运动量训练后血中上述 3种激素均明显降低 (P <0 .0 5 ) ,恢复期上升至训练前水平 ,尿中激素则在训练后和恢复期均明显增加 (P <0 .0 5 )。提示机体性激素水平的分泌和代谢受运动量的影响 ,同时存在性别间的差异。
Small loading and strengthening exercises were performed by 22 athletes(11 males and 11 females). The levels of serum hormones and their urinary metabolites were detected. The results showed that the serum levels of testosterone(T), free testosterone(FT) and 17 OH pregsterone(17 OHP) in male athletes exhibited no conspicuous changes. The excretion of their urinary androsteroids was significantly increased after exercises(P<0.05), but significantly decreased in the recovery period(P<0.05). After small loading exercises, their serum levels of T and FT revealed no obvious changes except those of 17 OHP which evidently increased in female athletes(P<0.05); whereas the excretion of their urinary steroid hormones declined promptly after the exercises and in the recovery period (all P<0.05). After strengthening exercises, the serum levels of T, FT and 17 OHP decreased distinctly in female athletes (all P<0.05), the excretion of their urinary steroid hormones raised clearly after training and in the recovery period(P<0.05). Therefore, it is suggested that the secretion and metabolism of sex hormones in the organism are influenced by the loading quality of sports during training, and sexual difference exists simultaneously.
