تاثیر فشار وزنه برزاویه شیب مفصل ران در افراد وزنه بردار

ABSTRACT: Radiographic techniques were used to determine the incliniation angle i.e. the angle between the neck and shaft of the femor(S/N angle )in weightlifters and nonathletes of two age groups Under 21 years (Group 1)and above 21 years(Group 2). Statistical methods were used for analyzing the data obtained by the radiographic techniques . The results showed that the physiologic response against the Stress due to weight lifting through bone formation was significantly high.As a result,the density and diameter , and inclination angle of femor in weightlifters were higher than those in nonathletes .A marked increase in the diameter of the shaft of the femor in weightlifting in the younger group was higher than that in the older group
