目的探讨不同成熟水平青年运动员抗阻运动诱导激素反应的差异。材料与方法：共招募12名大学男运动员和32名初中男运动员。根据初中生的PHV年龄分为PHV前组和PHV后组。在进行体重抵抗运动之前（前）、之后（后）和15分钟后分析唾液睾酮、皮质醇和人类生长激素水平。结果大学生睾酮水平高于初中生组（P< 0.01），运动15 min后睾酮水平升高（P< 0.01）。初中生组运动后皮质醇水平显著降低（P< 0.01）， phv后组运动后15分钟人体生长激素水平显著升高（P< 0.01）。在大学组和运动后组，在运动后和运动后15分钟，睾丸激素对皮质醇的比值升高（P< 0.01）。在运动前和运动后15分钟，大学生的睾酮对皮质醇比值值高于运动后[P< 0.05]。[P< 0.01])和phv前组（所有时间[P< 0.01]）。结论抗阻运动引起的急性激素反应可能取决于个体的成熟程度，即使在年龄相同的人群中也是如此。
PurposeTo examine differences in resistance exercise-induced hormonal responses among young athletes according to their maturity levels.Materials and Methods:A total of 12 collegiate and 32 junior high school male athletes were enrolled. The junior high school participants were divided into pre–peak height velocity (PHV) and post-PHV groups, according to their PHV ages. The salivary testosterone, cortisol, and human growth hormone levels were analyzed before (pre), immediately after (post), and at 15 minutes after performing body weight resistance exercise.ResultsThe testosterone levels were higher in the collegiate than in the junior high school group (P< .01) and increased after 15 minutes of exercise (P< .01). A significant decrease in the cortisol levels postexercise in the junior high school groups (P< .01) and an increase in the human growth hormone levels at 15 minutes after exercise in the post-PHV group were observed (P< .01). In the collegiate and post-PHV groups, the testosterone-to-cortisol ratio increased post and at 15 minutes after exercise (P< .01). The testosterone-to-cortisol ratio values were higher in the collegiate than in the post-PHV (at preexercise and at 15 min after [P< .01]) and pre-PHV groups (at all times [P< .01]).ConclusionExercise-induced acute hormonal responses to resistance exercise may depend on individuals’ maturity levels, even in those having the same age.
