Outline of Final Research Achievements

We directly assessed active muscle stiffness according to actual length changes in muscle fibers during short range stretching. Using this technique, we found that active muscle stiffness of long distance runners was significantly higher than that of untrained subjects, whereas that of sprinters was not. Furthermore, active muscle stiffness and the tendon elongation during ballistic contractions significantly increased after 12 weeks of plyometric training, and these changes may be related to improved performances during stretch-shortening cycle exercises.
