Abstract: The study measured short distance runner's peak torque of extensor and flexor of knee joint and hip joint at angular veloctiy of 60º/s,180º/s.,300º/s., discussed the correlation between this measurement re sult and different running distance. It is discovered that the peak torque of extensor is far larger than that of flexor at different angular velocity. It is also discovered which highly relate to 100m running time and 100 m acceleration time is the extensor torque of knee joint at angular velocity of 300º/s. and that of hip joint at angular velocity of 180º/.
Key words: extensor; flexor; peak torque; angular velocity; cor relativity |
