Outline of Final Research Achievements

In this study, we have investigated the structural and functional characteristics of hamstrings using shear wave elastography, and the following facts were clarified: ① the muscle hardness of distal portion of hamstrings was harder than middle and proximal portion. ② the muscle damages in biceps femoris than semimembranosus were larger than that in semitendinosus after eccentric contractions.
