A Study On The Influence Of Small Basketball On The Physique Of 5-Year-Old Children

The good physical quality of young children is not only an important basis for the health level of individuals in the whole life cycle,but also related to the national health strategy of the whole country.However,at present,the physical health level of young children is not optimistic.Studies have proved that small basketball can not only promote the development of bones and organs,but also promote the development of sensitive response,vertical jump,speed and so on.In order to further explore the effect of small basketball on children’s physique,this study is based on the relevant provisions of the Sports Development Guide for 3-and 6-year-old Children and the Fifth National physique Monitoring(Children’s part),on the basis of consulting a large number of related literature.the methods of literature,interview,experiment and mathematical statistics were used to study the 5-year-old children of natural tree kindergarten in Zhengzhou.The subjects were randomly divided into experimental group and control group.Before the beginning of the experiment,physical fitness tests were carried out on the students in the experimental group and the control group,mainly including body shape test,physical function test and physical fitness test,involving a total of 9 test indicators.Before the beginning of the experiment,physical fitness tests were carried out on the students in the experimental group and the control group,mainly including body shape test,physical function test and physical fitness test,involving a total of 9 test indicators.At the end of the experiment,the indicators of the two groups of children were tested again,and the data were statistically analyzed.The conclusions and results are as follows:Results of the study:(1)after 12 weeks of experiment,the body shape indexes of children in the experimental group and the control group changed to a certain extent.In the experimental group,the height of male and female children increased by 1.1cm and0.8cm respectively,and the weight increased by 0.5kg and 0.4 kg respectively,while in the control group,the height of male and female children increased by 0.8cm and0.7cm respectively,but there was no significant difference.(2)after 12 weeks of experiment,the physical function indexes of children in the experimental group and the control group were improved,but there was no significant difference(P > 0.05).(3)after 12 weeks of experiment,the physical fitness indexes of children in the experimental group and the control group were improved.In the experimental group,the continuous jump of both feet increased by 0.8s,the 15 m running around the obstacle by 1.2s and 1.5s,the walking balance beam by 0.8s and 0.6s,the grip strength by 1kg and 1.2kg,the standing long jump by 2.4cm and 3.6cm,and the sitting forward flexion by 2.2cm and 1.2cm respectively.In the control group,the continuous jump of male and female children increased by 0.3s and 0.2s respectively,the 15 m running around the obstacle increased by 0.1s and 0.4s,the walking balance beam increased by 0.6s and 0.8s respectively,the grip strength increased 1.1kg and 1.1kg respectively,the standing long jump increased 0.5cm and 1.6cm respectively,and the sitting forward flexion increased 2.5cm and 0.4cm respectively.The results of independent sample T test of the two groups of data showed that there were significant differences in the indexes of continuous jump and walking balance beam in male children(P < 0.05),and in running around obstacles in 15 meters(P < 0.01).There were significant differences in female children’s continuous jump(P < 0.05),walking balance beam(P < 0.05),grip strength(P < 0.05)and standing long jump(P< 0.05).Research conclusion:(1)after the experiment,the height and weight indexes of the experimental group and the control group increased,and there was no significant difference,but the body shape index of the experimental group increased greatly.It is suggested that small basketball has no obvious effect on the body shape of 5-year-old children.(2)after the experiment,there was no significant difference in the quiet pulse between the two groups,but the quiet pulse index decreased more in the experimental group,suggesting that small basketball had no obvious effect on the physical function of 5-year-old children.(3)after the experiment,there were significant differences in the indexes of continuous jump and 15 m running around obstacles between the two groups of male children,and there were significant differences in the indexes of continuous jump,walking balance beam,grip strength and standing long jump between female toddles.it is suggested that small basketball can promote the development of children’s coordinated quality,and has a more positive effect on male children’s sensitivity and speed quality.It plays a more obvious role in balancing quality and strength quality of female children.
