Maturity-Associated Longitudinal Variations in Exercise-Induced Acute Hormonal Responses in Adolescent Male Athletes.
Purpose: To examine longitudinal changes in exercise-induced hormonal responses in adolescent male basketball players.
Methods: Fifteen adolescent males were assigned to prepeak height velocity (pre-PHV) and post-PHV groups according to the predicted age at PHV. Salivary testosterone, cortisol levels, and the testosterone-to-cortisol ratio were evaluated before (PRE), immediately after (POST), and 15 minutes after a bodyweight resistance training session, which was repeated after 1 year to analyze longitudinal changes in testosterone and cortisol levels.
Results: Resting testosterone levels and acute testosterone responses after bodyweight resistance training increased in both groups after 1 year at all measurement points. The POST testosterone levels at initial measurement and PRE and 15-minute postexercise levels at 1 year in the post-PHV group were significantly higher than those in the pre-PHV group. Cortisol levels significantly decreased in the post-PHV group at baseline and 1 year later. In the post-PHV, the testosterone-to-cortisol ratio after bodyweight resistance training was significantly increased at baseline and 1 year later.
Conclusions: Although testosterone levels increase with age, no acute response to bodyweight resistance training was observed after 1 year. The change in anabolic status indicated by the testosterone-to-cortisol ratio was due to a decrease in cortisol levels.
期刊介绍：
Pediatric Exercise Science is a journal committed to enriching the scientific knowledge of exercise during childhood and adolescence. To this end it publishes information that contributes to an understanding of (a) the unique aspects of the physiologic, physical, biochemical, and psychologic responses of children to exercise, (b) the role of exercise in the treatment of pediatric chronic diseases, (c) the importance of physical activity in the prevention of illness and preservation of wellness, and (d) the means by which participation in sports may be made safer and more enjoyable for children and youth. Consideration will be given for publication of work by various methodologies consistent with the scientific approach.
Besides original research, the journal includes review articles, abstracts from other journals, book reviews, and editorial comments. Pediatric Exercise Science encourages the expression of conflicting opinions regarding children and exercise by providing a forum for alternative viewpoints. At the same time it serves as a means of accumulating a base of research information that will allow application of experimental data to clinical practice. The scientific disciplines contributing to this body of knowledge are diverse. Therefore it is the purpose of this journal to provide a common focus for disseminating advances in the science of exercise during childhood. In doing so, the journal allows the opportunity for cross-fertilization of ideas between disciplines that will potentiate the growth of knowledge in this field. Pediatric Exercise Science seeks to stimulate new ideas regarding exercise in children and to increase the awareness of scientists, health care providers, and physical educators of the importance of exercise during childhood.
