| Outline of Final Research Achievements |
The primary purpose of this study was to investigate the relation between development of motor-ability and individual maturation, which was evaluated by using peak height velocity age (PHVA) in adolescent male and female soccer players. Secondly, we aimed to investigate the reliability and validity of “maturity offset method” which estimate PHVA. In addition, we aimed to establish reference data of motor-ability of youth soccer players. The results of this study showed that jump ability developed after one-year post-PHVA in females and two years post-PHVA in males, and changes in lean body mass had no correlation. The change of direction ability developed during pre-PHVA, with the effect of the improvement of deceleration ability. On the other hand, there were no differences in intermittent exercise ability among each maturation stage. Lastly, the study found that the maturity offset method has low reliability for Japanese children.

| Academic Significance and Societal Importance of the Research Achievements |
成長期の男女サッカー選手の各種運動能力の発達はすべて成長段階によって異なると考えられてきたが、実際にはその年間発達が成長段階の影響を受けるものと受けにくいものに分類できることが明らかとなり、今後の発育発達研究に新たな分析視点をもたらしたことは学術的に意義深い。特にパワー系能力はPHVA以降に発達することが示され、この時期に焦点を当てたトレーニング指針作成に貢献できる点で臨床上の有用性は高いと考える。さらに既存のMaturity Offset法は日本人の場合、低年齢ではPHVAを低く見積もる（早熟傾向）ため、値を補正する必要性を明らかにしたことも臨床上は意義深いと考える。
