In the optimized modeling study on joint movement amplitude and sports injury,reasonable research on the relationship between joint movement amplitude and sports injury can usefully avoid injuries.The connection between the joint movement and injury is in high random condition,and injuries are related with several variable factors such as movement angle,environment,etc.In order to solve the above problem,an expressing method for the relationship between joint movement amplitude and sports injury was proposed based on rough set decision algorithm.Based on rough set related theory,all the joint movement amplitude data and the sports injury data were simplified to get the corresponding decision table.According to the movement data in decision table,the optimal hyperplane of the relationship between joint movement amplitude and sports injury was obtained.The needed satisfied constraint condition of the optimal hyperplane was obtained to establish the relation model of joint movement amplitude and sports injury.Experimental results show that the improved algorithm to establish the relation model of joint movement amplitude and sports injury can greatly improve the accuracy of the above relationship expression and provide some scientific basis for avoiding the occurrence of sports injury.
