Outline of Final Research Achievements

The aim of this study was to investigate the impact of children's growth and development, as well as their exercise habits, on the enhancement of agility in elementary and middle school-aged children. Specifically, we examined the influence of exercise habits on the relationship between height gain and agility improvement. The results revealed that children without exercise habits displayed an early inflection point during the phase of height growth. In contrast, children with exercise habits exhibited the inflection point at a higher height compared to those without exercise habits. Furthermore, among children with exercise habits, there was a distinct deceleration in agility development following the occurrence of the inflection point. These findings suggest that exercise habits influence the developmental enhancement of agility in children. Further studies are necessary to elucidate the underlying mechanisms and explore potential gender differences in this regard.

Academic Significance and Societal Importance of the Research Achievements

小中学生期における運動経験や運動習慣は、知覚・意志決定要素に影響するため，発育要因とは独立した運動習慣の要因が，アジリティ向上に対して影響を及ぼす考えられる．申請者の研究グループが開発したN CHALLENGE測定システムは，高い独自性と信頼性を有している．また，リバウンドジャンプ遂行能力は，極めて短時間の運動における「先取り能力」が評価できる．さらに，アロメトリー分析を用いることにより，身体発育との関係性を詳細に分析できる．このような複合的アジリティ評価に基づいた本研究の成果は，小中学生期におけるアジリティ向上のメカニズムの理解にとって大きな進展をもたらす可能性がある．
