Outline of Final Research Achievements

This study aimed to investigate the development of maximum muscular strength of lower limb in elementally school children and to examine the association with sprint performance. The participants, who were the 2nd and 6th grade male children, performed the tests consisting of isometric maximum muscular strength and 30m sprinting. Although the sprint performance was not correlated with maximum muscular strength of lower limb in 2nd grade children, it was fount the significant association between them in 6th grade children. The relationship between maximum muscular strength of lower limb and sprint performance is depending on age, suggesting that the importance of the training intervention according to the growth situation for each child.

Academic Significance and Societal Importance of the Research Achievements

本研究は，アイソメトリックな力発揮を実験室外で実施できる測定装置を用いて，子どもの最大筋力を測定し，疾走能力との関係を検討した．これまで，下肢の最大筋力は，膝関節伸展筋力などの単関節運動によって評価されてきたが，本研究の方法を用いることで，下肢全体の最大筋力を測定することができる．
また，年齢に応じて，下肢の最大筋力と疾走能力との関係が異なり，小学6年生にのみ強い相関関係が認められた．これは，小学校高学年の児童に対しては，下肢の最大筋力を高めるトレーニングの効果を支持するものであり，学校現場などで下肢筋力を高めるための取り組みの重要性を示している．
