The Improvement And Practice Of Badminton Back-court Technique For Amateur Junior Players Based On Decomposed Coaching

In this study,teaching experiment,literature research,questionnaire survey and mathematical statistics are used.The improved teaching method of back-court basic stroke is taken as the research content.The trainee aged 6-14 in the amateur class of youth badminton are taken as the research objects.The multi-shuttle feeding method is used to group teaching the research objects.In order to provide feasible suggestions and basis for the teaching of badminton back-court basic hitting action,the training effect of traditional and improved teaching methods is compared by using the way of hitting point.Considering the complex internal relationship between different influencing factors,this paper adopts the machine learning method based on support vector machine method,and takes the test results as the training set to train it.Through the training model,the possible training effect is predicted,and the most suitable training crowd is obtained.The main results of this paper are as follows:(1)For students of different ages,the evaluation indexes of the improved teaching method are better than the traditional teaching method;But with the increase of age,the difference between the two kinds of training effect gradually decreases.(2)For the students with different height and weight,the flying distance and landing accuracy of the high ball in the back court are significantly improved by using the improved teaching method,but there is no significant difference in the improvement effect of the hit rate.(3)As for the influence of gender on the training effect,the test results show that the flight distance and landing accuracy of the high ball in the backcourt of female students are significantly improved after adopting the improved teaching method,but the hit rate does not show significant difference in the gender of students.(4)Support Vector Machine(SVM)is used to predict the test results.The results show that the accuracy of the method is good.The prediction results show that the most suitable age for the improved teaching method is boys under 15 years old and girls under 14 years old.The main conclusions of this paper are as follows:(1)Overall,the improved teaching method has the most obvious effect in improving the students’ power.When the students adopt the improved teaching method,the two technical indexes of the flying distance and the accuracy of the landing point of the ball related to the power are significantly improved.(2)In the observation group,the training effect of the improved teaching method is more obvious for the students who are younger,female and less weight.(3)The prediction of training effect by using support vector machine shows that the improved teaching method of backcourt clear is not equally helpful for students of all ages,it is more efficient for boys under 15 years old and girls under 14 years old.
