| Outline of Final Research Achievements |
This study aimed to investigate the changes in muscle contraction response, muscle thickness, pannaition angle, and ankle maximal plantar flexion torque in SS and CS for 4 weeks, and to determine the appropriate stretching method before and after sports activities and to prevent sports injury.
The results of this study showed that long-term intervention of CS program to improve both Dm and Vc, and may improve muscle flexibility and increase the rate of muscle contraction. This study suggested that CS may also contribute to the improvement of muscle contraction speed, which may improve instantaneous sports performance.

| Academic Significance and Societal Importance of the Research Achievements |
Cyclic Stretching（CS）は筋パワーやパフォーマンスを向上させる効果を示していることは周知であるが，筋収縮速度の向上にも寄与する可能性があり，瞬発系のスポーツパフォーマンス向上という観点からもその臨床的意義は高いものと考える．
今後，CSの特徴を踏まえて，スポーツ現場における選手へのストレッチングを実施し，身体パフォーマンスの維持・改善に対して臨床応用ができるものと考えられる．
