| Basketball has become one of the most popular sports among the audiences.This sport has always been considered one of the most popular,demanding and competitive sports in the world.Current basketball players need not only excellent basketball skills,but also good strength level as the basis of ordinary training and competition.Traditional strength training parameters only focus on cardiopulmonary fitness,muscle endurance,muscle strength,flexibility and body composition.With the improvement of competitive level,athletes and coaches also begin to pay attention to and understand the core training,power chain stability,movement efficiency,balance and other contemporary training parameters.The core strength is a link that is easily ignored in traditional training.Because the promotion of core strength has a positive impact on athletes'performance,the research on core strength has become a hot topic.Research purposes:Shooting score is an important way to win the competition in basketball,so shooting percentage is also the core of the whole technical system of basketball.Therefore,this paper mainly takes core strength as the starting point,through core strength training to enhance core strength to study its impact on the shooting percentage of college basketball majors.Research methods:By means of literature,expert interviews,mathematical statistics and experimental methods,this paper studies the division of core areas and the definition of core strength,the role of core strength,the training methods of core strength and the main factors affecting shooting percentage.In this paper,a large number of books and materials are consulted through the literature research method to divide the core area in detail and determine the connotation of core strength.The role of core strength and the training methods of ordinary core strength of college basketball majors are thoroughly understood by means of expert interviews.Then,the main factors that core strength training affects their shooting percentage are discussed in detail through experimental and comparative analysis methods.Factor.This paper takes 24 students in basketball specialty course of Shaanxi Normal University as the research object,and divides them into experimental group and control group for 12 weeks of core strength training and traditional strength training respectively.The main factors affecting the shooting percentage are discussed thoroughly by testing the shooting percentage of 90s,fixed-point shooting and stopping shooting before and after the experiment.The results are as follows:(1)After the experiment,the percentage of fixed-point shooting was 59.33%in the experimental group and 56.67%in the control group.Through one-way ANOVA,F was 0.446,0.449,0.327,0.368,P was 0.511,0.510,0.574 and 0.550,respectively.Under the premise of a given value of 0.05,we can accept the original assumption that there is no significant difference between the different groups and the percentage of fixed-point shooting before and after the experiment.Different.(2)After the experiment,the 60 s shooting percentage of the experimental group was 65.00%,and the fixed-point shooting percentage of the control group was 57.92%.Through one-way ANOVA,the F value of the experimental group before and after the experiment was 4.902,and the corresponding P value was 0.037.On the premise of given a value of 0.05,the original hypothesis was rejected.It was considered that for the experimental group,the experiment would significantly affect the accuracy of the 60 s shooting,in addition,the other F values were 0.037.257,0.048,3.356,P values were 0.618,0.829 and 0.080,respectively.Therefore,accepting the original hypothesis,we can conclude that there is no significant difference in pitching accuracy between the control group before and after the experiment,and between the experimental group and the control group.(3)After the experiment,the shooting rate of the experimental group was 49.17%,and that of the control group was 41.39%.After one-way ANOVA,the F value of the experimental group before and after the experiment was 6.271,and the corresponding P value was 0.020.On the premise of a given value of 0.05,the original hypothesis was rejected.For the experimental group,the experiment would significantly affect the accuracy of dribbling stops.After the experiment,the F value of the experimental group and the control group was 5.479,and the corresponding P value was 0.028.On the premise of a given value of 0.05,the original hypothesis was rejected.It was considered that the experiment made the accuracy of dribbling stop shooting significantly different between the experimental group and the control group.In addition,the other F values were 1.783,2.129,and the P values were 0.195 and 0.159,respectively.Therefore,the original hypothesis could be accepted as the control group experiment.There was no significant difference in pitching accuracy between the experimental group and the control group before and after the experiment.Research conclusions:(1)Core strength will have a positive impact on all three kinds of shooting,and the effect of fixed-point shooting is not significant,because the athletes'body is in a relatively stable state in this state.The shooting score mainly depends on the strength of wrist joint and deltoid muscle and shooting technology,and has little relationship with the core strength of the body.But if it is 90 s fast shooting and dribbling,there will be a significant difference between the two kinds of training(2)Core strength emphasizes the core regional strength confrontation between athletes in high antagonistic competitions,so the core strength of college students has a decisive impact on shooting movements,and can effectively improve the physical quality and strength quality.However,the core strength has no significant effect on the shooting percentage in the stable state,but has a significant positive effect on the shooting percentage in the unstable state. |
