The said findings indicate the followings: 1) the exten-sor strength of the knee and ankle joints of the female handball players is greater than the extensor strength; 2) the proportion between the flexor strength and extensor strength of the right knee joint of the female handball players is irrational, while the proportion between the flexor strength and extensor strength of their ankle joints is rational; 3) the homonymous muscle strength of the left and right ankle joints of most tested players is unbalanced, which is re-lated to dedicated handball technique and strength training.
