| Objective: the high incidence of sports injury in martial arts is caused by the technical movements and the trainer’s own factors.Some researchers believe that Functional movement screening can predict the occurrence of injury.However,it is worth noting that the results of injury prediction of subjects in different subjects are different due to the influence of sports specialty as the main factor.By referring to relevant literature,there is no prospective research on martial arts students as subjects at home and abroad.Therefore,the prospective cohort design was adopted in this study to study whether functional motion screening can be used as a tool to predict sports injury of martial arts college students.Methods: martial arts students from Beijing sport university who met the inclusion criteria were selected,and a 16-week prospective cohort study was conducted on the prediction of sports injury of martial arts students by functional motion screening.ROC curve,multivariate logistic regression,Spearman’s coefficient analysis and other statistical methods were used to compare and analyze the predicted results of injury and the actual occurrence of injury,so as to analyze the accuracy of the prediction of sports injury of subjects by functional motion screening.Results: the average score of Functional movement screening was 14.80±2.26,the incidence rate of thousand-hour injury was 63,and the injury types were mainly moderate and severe.According to the ROC curve calculation results,15 points(AUC: 0.637,95%CI: 0.480-0.794)is the critical value of injury prediction for martial arts students.According to this critical value,the predictive value between injury and degree of injury was analyzed.The data analysis results between each indicator and injury showed that the injury risk of martial arts students increased by1.60 times with the increase of age(OR=1.60,95%CI: 1.10-2.34,P=0.01).Compared with the previously uninjured subjects,the former had 17.55 times the risk of injury during the follow-up period(OR=17.55,95%CI: 1.1-284.35,P=0.04).In addition,for every 1 point increase in the score of squat test,the possibility of injury was reduced by 3.89 times compared with those with low scores(OR=3.89,95%CI:0.99-15.36,P=0.05).As far as the degree of injury is concerned,the total score of the test for minor injuries is below the critical value(Se=1.00,95%CI: it cannot be calculated;FNF=0,95%CI: unable to calculate;NPV=1,95%CI: impossible to calculate),but when the critical value is used to predict mild injury,the true negative rate is low and the misdiagnosis rate is high(Sp=0.47,95%CI: 0.32-0.62).FPF= 0.53,95%CI: 0.38-0.68;PPV = 0.1,0.04 0.32;Consistency =0.51,95%CI: 0.37-0.65).In addition,there was no statistically significant difference between each indicator and the degree of injury(P>0.05).Conclusion: when functional motion screening is used as the sports injury prediction standard for martial arts students,the accuracy of the prediction is not high,so it should not be applied to the prediction of martial arts students.The experimental results showed that there was a statistical correlation between age,previous injury status,squat test results and the actual occurrence of injury,but whether the above indicators can be used as an evaluation index of injury prediction needs further study. |
