The power training of beach sports has gradually become a new method of increasing the muscle strength and improving the athletic performance. Anklebone ligamentous injury accounts for a large proportion in the athletic injury. Therefore, in order to improve the quality of beach sports power training, it is necessary to establish the relationship model of ankle joint injury caused by the power training of beach sports, and to study the effect of beach sports power training on ankle joint injury. However, when the current model is used to analyze the impact of beach sports power training on the injury of ankle joint, the principal component of effect of beach sports power training on ankle joint injury cannot be given, and the analysis precision is low. To this end, we proposed a model to evaluate the effect of beach sports power training on ankle joint injury. This method uses the principal component analysis theory to extract the maximum principal component of the effect of training on the ankle joint injury, and calculates the LASSO-Granger causality measurement values between the principal components. The kernel matrix of the principal component feature space is given and input in the support vector machine classifier which represents influence of training on ankle joint injury. The principal component characteristics of each influencing factor are marked, and the correlation between marked characteristics is obtained, and a new output kernel function is constructed. Based on this, the study on the impact of beach sports power training on ankle joint injury is completed. Simulation results showed that the accuracy of the proposed model is high, which can effectively ensure the smooth power training of beach sports and enhance the quality of beach sports power training.
