An Study Of The Effect Of Small Basketball Practice On Gross Motor Development In Children Aged 7-8 ——A Case Study Of Nanxinzhuangzi Central Primary School

Research purpose: To explore the influence of small basketball practice as the teaching content of physical education and health course on the development of big muscle movement and its sub items of children aged 7-8 years.Research methods: 60 children in grade one of nanxinzhuangzi Central Primary School in Zunhua City,Tangshan City,Hebei Province were randomly selected and divided into experimental group(16 men and 14 women)and control group(15 men and15 women).The experimental group and control group took small basketball practice and routine physical education and health courses as teaching contents respectively.Before the experiment,60 children aged 7-8 were tested for their height,weight and age,and the development of large muscle movement without statistical difference.After the experiment,the development of large muscle movement was tested.Results:(1)in terms of the development of displacement movement,there was no significant difference in the scores of each movement test before and after the experiment in the control group;Compared with before and after the experiment in the experimental group,the test scores of running,step jumping and forward sliding steps increased significantly(P < 0.01),while the test scores of side sliding steps increased slightly(P <0.05);After the experiment,compared with the control group,the test scores of running,forward sliding step and side sliding step and the total score of displacement action in the experimental group increased significantly(P < 0.01),while the test scores of standing long jump,single foot jump and step jump increased slightly(P < 0.05).(2)In terms of object manipulation,compared with the control group before and after the experiment,the test score of hitting the fixed ball increased significantly(P <0.01);Compared with the experimental group before and after the experiment,the test scores of hitting the fixed ball,throwing the ball with the upper hand and rolling the ball increased significantly(P < 0.01),while the test scores of kicking the ball and catching the ball with both hands increased slightly(P < 0.05);After the experiment,compared with the control group,the test scores of kicking,throwing and groundball movements and the total scores of object control movements in the experimental group increased significantly(P< 0.05).(3)In terms of the development of big muscle movement,there was no statistical difference in the total score of big muscle movement development in the control group before and after the experiment.Compared with the experimental group before and after the experiment,the total score of big muscle movement development in the experimental group increased significantly(P < 0.01).After the experiment,compared with the control group,the total score of big muscle movement development in the experimental group increased significantly(P < 0.01).Conclusions:(1)small basketball practice can significantly improve the displacement and object manipulation of 7-8-year-old children;(2)Small basketball practice can better promote the development of big muscle movement of 7-8-year-old children than the teaching content of routine physical education and health course.
