Comparative Study of Carrying Angle Among Athletes in Selected Sports and Non-athletes in South-South and South-East Nigeria
The study was carried out to compare the carrying angle of athletes in selected sports and non-athletes in South- South and South-East Nigeria, from age 22 to 36years old. Measurements were done using universal goniometer and flexible curve. A total of four hundred and seventy-two (472) males (140 non-athletes and 136 athletes) and female (115 non-athletes and 81 athletes) subjects were selected from South-South and South-East Nigeria using a purposive sampling technique for athletes and simple random sampling for non-athletes. Themean value and standard deviation of rightcarrying angle (RCA) for male is 11.00±2.460 for non-athletes and 11.79±2.440 for athletes while that of the female is 14.12±2.830 for non-athletes and 16.11±2.670 for athletes at p < 0.001. The mean value and standard deviation of left carrying angle (RCA) is 9.66±2.280 for male non-athletes and 9.89±2.280 for male athletes while that of the female is 12.47±2.590 for non-athletes and 13.39±1.950 for athletes at p < 0.001. Statistical analysis using T-test showed that the carrying angle is significantly higher in athletes (male and female) than in non-athletes at p<0.001 indicating changes in the alignment of anatomical structure due to sporting activities. The carrying angle is also significantly higher in females than in males at p<0.001 which indicates sexual dimorphism. The knowledge of these values is important because normal values of carrying angles are useful parameters in clinical anatomy, evaluation, repair and counselling in sports.
