Outline of Final Research Achievements

This study was to clarify the relationship between shoulder muscle strength and swimming power of junior swimmers. The subjects were 20 junior swimmers, and a simple swimming power measuring device was used to measure the maximum swimming power(MSP). The maximum isometric force of shoulder joint was measured using a hand-held dynamometer. The extension force of the maximum abducted position(MAP) was measured at the shoulder positioned with maximum shoulder abduction, with the elbow extended, and with the forearm in a neutral position. The internal rotation force of the abducted and external rotated position(AEP) was measured at the shoulder positioned with 90 degrees of shoulder abduction and 90 degrees of external rotation, with the elbow at 90 degrees of flexion, and with the forearm in a neutral position.
The results showed a significant correlation between MSP and MAP and AEP among all subjects, suggesting that improving shoulder strength is effective for junior swimmers.

Academic Significance and Societal Importance of the Research Achievements

本研究において、ジュニア水泳選手における肩関節筋力と泳パフォーマンスとの関係性が明らかとなった。これまでの研究では大学生競泳選手を対象としており、すでに大学生競泳選手では肩関節筋力と泳パフォーマンスとの間に有意な相関関係が認められていた。本研究結果を受けて、成長過程におけるジュニア競泳選手においても肩関節筋力の向上のための特異的なトレーニングを実施する必要性が明らかとなった。このことにより、将来的にオリンピックや世界選手権等の国際大会を目指すジュニア競泳選手の競技力向上に貢献できるものと考えられ、国内における競泳競技のレベル向上のために寄与することができる。
