Experimental Study On The Effect Of Basketball On Executive Function Of Obese Children

Objective: Since 2015,the proportion of obese people of all ages in my country has been increasing,and the obesity rate in primary and secondary schools has exceeded 10% by 2020.The harm caused by obesity is not only reflected in the growth and development of children,but also will threaten the physical and mental health in the later period if no timely intervention is taken.It is urgent to solve the physical health problems of children in our country.Studies have shown that children’s executive function level is closely related to BMI,and children with poorer executive function have more obese behaviors.Studies from normal-weight children suggest that children’s executive function can improve and that exercise is one of the most economical interventions available.Many scholars have found through further research that basketball can bring more significant improvement to the executive function of normal-weight children than regular physical activities.Therefore,this study aims to improve the physical health of obese children,uses basketball to improve the executive function of obese children,explores the effect of basketball on the executive function of obese children,and provides a basis for using exercise methods to improve the physical and mental health of obese children.Research methods: The main research methods of this study are literature,expert interview,experiment and mathematical statistics.Forty obese children aged 10-12 were selected as experimental subjects and randomly divided into experimental group and control group with 20 children in each group.The experimental group received basketball intervention three times a week for 8 weeks.The control group had sports club activities organized by the school at this stage.The subjects’ BMI and executive function were tested before and after the experiment,and SPSS was used to compare and analyze the test data later.Research results:1.After 8-week basketball exercise intervention in the experimental group,independent sample T test was used to compare and analyze the executive function and BMI test data of the experimental group before and after the experiment,and three indicators of executive function were obtained: That is,the P values of inhibition function,refresh function and conversion function were all <0.01,indicating that the executive function of the experimental group was significantly improved,and BMI was also significantly decreased(P < 0.01).2.After the control group participated in sports club activities for 8 weeks,the paired sample T test was conducted on the executive function and BMI test data of 20 subjects in the control group before and after the experiment.The results showed that:The three sub-functions of executive function were suppression function(P =0.23),refresh function(P=0.083)and conversion function(P=0.58).The P values of the three indexes were all greater than 0.05.Although the three sub-functions of executive function in the control group all changed,but not significantly.BMI(P < 0.01),BMI had a significant decline.3.Independent sample T test was used to compare and analyze the post-test data of the two groups,and the post-test data of executive function were obtained between the two groups: inhibition function(P < 0.01),refresh function(P < 0.01),conversion function(P < 0.01),and the three indicators of executive function were all less than0.01,showing significant differences.However,there was no significant difference in BMI between the two groups(P=0.168).Conclusions:1.Basketball exercise can comprehensively improve executive function and effectively reduce BMI in obese children.2.The positive effect of basketball on executive function of obese children was more significant than that of sports association activities.
