Abstract
Introduction: Various causes and factors are involved in incidence of sports injuries that whose identification is one of the major goals of sports scientists. Therefore, identification of the causes and factors causing injuries which can be called as a risk factor for a sports, can be effective in reducing and preventing athlete’s injuries. Therefore, considering the high incidence of injury in taekwondo, the objective of this prospective study was survey the relationship between the internal risk factors of lower extremity with injuries incidence rate of the teenage boy taekwondo players.
Methodology: For this purpose, 60 teenage taekwondo players of Taekwondo Premier League participated voluntarily in this research. Before league commencement, navicular drop, Q angle, knee hyper extension angle, dorsiflexion/plantar flexion range of motion, hamstring flexibility and their dynamic balance were measured. Then the injuries of these taekwondo players were recorded for a period 3 months.
Results: During the study, 37 injuries were recorded that the injuries incidence rate was 7.9 per 1000 hours of exposure (95% Confidence interval, 5.33 – 10.40). Also results of logistic regression indicated that there is significant relation between the Q angle and injuries incidence rate (OR=1.33, P=0.031). Those taekwondo players whose Q angles are more than 14.5 cm, will be 1.33 times more prone to Lower limb injury. But as for the other risk factors study cases, no significant relationship was observed with injuries incidence.
Discussion: Based on research results, scores of Q angle can predict lower limb injuries of taekwondo players. Therefore, it is suggested that this index to be evaluated before the start of the tournament. Also, according to the findings, it seems that the other risk factors of investigated in this study in predicting Taekwondo injuries they have not been successful, which is consistent with the results of some similar studies. However, to confirm or disapprove this risk factor as a predictor of injury in Taekwondo players, need more research.
