The subjects examined were 398athletes. The method used included both questions and clinical examination. The differences of the data obtained all underwent Chi Square (X~2) test. Result of the investigation showed: the site of the highest incidence of injury was the ankle, 38.4%; the nextwas the knee, 26. 1%; the foot, 15. 3%; low back, 10. 3%; the thigh, 6. 8%; Tendo Achilles, 6. 5%; tibia, 4. 5%and fibula, 2. 3%. The incidence was relatively higher wbenever the injury had any relation with the shape ofthe knee (genu valgum, genu recurvatum), hallux Yalgus, c avus and callus and tarsal navicular. The differencesamong incidences of injury related with the shape of the lower limbs are of important statistical significance.As for the incidence of abnormal shape of limbs, genu valgum and recurvatum are outstanding in female wbilegenu varum occurs much more in male. This article is emphasized on the analysis of the mechanism of the influence of limb shape on injury;and it is thought that it is mainly due to changes in the line of force. In the authors' opinion, in the choiceof high level athletes, those who have such abnormal anatomy of their limbs should not be selected.
