Outline of Final Research Achievements

Although it has been suggested that the characteristic structure of the Achilles tendon may be involved in the mechanism of Achilles tendon disorders, there have been no reports focusing on the mechanical properties of each type of torsion. Therefore, the purpose of this study was to investigate the differences in mechanical properties of Achilles tendons for each type of torsion. The results showed that the stiffness, Young's modulus, and hysteresis of mild and severe torsion types were significantly lower than those of moderate torsion types. The results of this study revealed that the mechanical properties of the tendons were different for each type of torsion. The results also suggest a relationship between mild and severe torsion types and tendon damage.

Academic Significance and Societal Importance of the Research Achievements

アキレス腱の捻れのような特徴的な3次元構造は，スポーツ障害が好発する部位の筋腱組織がもつ特徴の1つである（棘上筋腱，長趾屈筋腱など）．本研究のように，腱構造と可塑的変化が期待できる腱特性との関係性を解明することにより腱障害の予防法を開発する試みは，非常に独創性が高く，未だ確立されていない数多くのスポーツ障害の予防法の確立へのブレイクスルーとなり得る．
