Outline of Final Research Achievements |
Human locomotion is performed by the coordinated activity of multiple muscles. One method for clarifying this intermuscular coordination is muscle synergy analysis. This study used muscle synergy analysis to investigate the relationship between athlete performance and muscle synergy. First, we conducted a longitudinal study of the performance and muscle synergy of the shot put athletes. The results revealed that as performance (records) improved, muscle synergy also changed. Next, we compared muscle synergy during successful and unsuccessful shooting of free throws in basketball. The results revealed that muscle synergies differed depending on the success or failure of the shot, even though the movements appeared to be similar.

Academic Significance and Societal Importance of the Research Achievements |
縦断調査から、パフォーマンス向上とともに筋シナジーが変化した。これはトレーニングが順調に進んでいるかの視標になる可能性がある。 また、シュートの成否によって筋シナジーが異なることが明らかとなった。このことから、筋シナジーはシュート動作を習得するあるいはより精度を高めるうえで、目に見える形でパフォーマンスを評価できるものと推測される。 上記より、筋シナジーを評価することは、トレーニングをより効率的に進め、パフォーマンスを向上させるうえで有益な情報となりうることが示唆された。
