| （Beijing Sport University，Beijing 100084，China） Abstract: By running an isokinetic test on the hip joints and knee joints at both sides of two high performance fe-male hammer athletes, the authors probed into the biomechanical characteristics of muscles surrounding the hip joints and knee joints of the athletes, so as to provide a theoretical criterion for sports training and sports rehabilita-tion. By utilizing an isokinetic muscle strength testing system, the authors ran an isokinetic test on the flexors and extensors of the hip joints and knee joints as well as the intortors and extortors of the hip joints of the two athletes, and revealed the following findings: the peak moments of the flexors and extensors of the hip joints and knee joints at both sides as well as the intortors and extortors of the hip joints of the two athletes showed a trend of decreasing with the increase of the test speed; the ratio of flexion peak moment to extension peak moment of the hip joints and knee joints and the ratio of intorsion to extorsion of the hip joints showed a trend of increasing with the increase of the set test speed; at the same test speed, the peak moment of extensors was greater than the peak moment of flex-ors, while the peak moment of extortors of hip joints was greater than the peak moment of intortors.
