Outline of Final Research Achievements

In this study, acute and chronic effects of muscle hardness changes induced by stretching or resistance training on muscle force production were investigated. The static stretching of the triceps surae decreased the hardness of the gastrocnemius muscle both temporarily and chronically, but did not change the plantar flexion strength. The resistance training of the elbow extensors increased the triceps brachii hardness temporarily, but the muscle hardness was not changed before and after the 6-week training program. On the other hand, the resistance training increased the elbow extension strength significantly. Thus, it is suggested that the changes in muscle hardness induced by stretching or resistance training do not correspond to that in muscle force production.
