| Research Abstract |
The purposes of the present work were to investigate the differences in morphology and functions of muscle-tendon complex in Japanese and Kenyan distance runners, and to relate the results to race performance. The comparison between Japanese and Kenyan data, and between different performance groups in Japanese suggested the possibility that the race performance is related to morphology of lower leg, tendon geometry, muscle stiffness and tendon compliance. In particular, the passive torque of ankle joint and muscle stiffness were significantly higher by 52% and by 181% in Kenyan than in Japanese, respectively. In addition, these parameters showed positive correlations to race performance (R=0.58, 0.53) in Japanese distance runners.
