Outline of Final Research Achievements

The purpose of the present study was to clarify maturity-based changes in athletic performance, morphology, exercise-induced hormonal responses, and adaptation to exercise among different maturity groups. The results of the cross-sectional analysis suggested that the hormonal response to training, which has an important role in anabolism, may depend on the individual’s maturity status. Furthermore, in a longitudinal analysis of the adolescent groups (junior high school age), testosterone levels increased with growth after age at peak height velocity; however, no acute response to body weight resistance training was observed. These results indicated the importance of carefully considering the training load and goal setting for adolescent males.

Academic Significance and Societal Importance of the Research Achievements

成熟度の遅速に関わらず，中学生年代の男子におけるホルモンのトレーニング応答は成人に比べて低いことが明らかとなり，成長期という限られた期間におけるトレーニングプログラムの目標設定および変数の選択に対する臨床的な有用性および成長期におけるスポーツ科学研究を進める上で学術的な意義は高いと考えられる．また，成熟度を考慮して安全且つ効果的にトレーニング処方を行うことが求められる指導者，トレーナーに対するトレーニング負荷や目標設定を慎重に検討する必要性の示唆は社会的な意義が高いと考えられる．
