An Experimental Study On The Effect Of Natural Foot Movement On The Growth And Development Of Preschool Children

Objective: The plasticity of preschool children's exercise habits is large.The growth and development of this period has a profound impact on the future physical health.This paper takes the influence of Tianzu exercise on the growth and development of preschool children as the starting point,through the height,weight and bone age.Analyze the changes of important indicators,explore the actual effects of Tianzu exercise on the growth and development of young children,and provide effective physical activity methods for improving the growth and development of young children and promoting the healthy growth of children.Methods: This paper mainly uses methods such as literature data,experimental methods,and mathematical statistics.Taking 207 small class children from two kindergartens affiliated to Xuezheng Education Group in Jianggan District of Hangzhou as the experimental object,Xuezheng Park was designated as experimental group(N=154),Wenqing Park was designated as control group(N=53),and the experimental group was carried out.Tianzu exercise intervention,the normal control wear shoes,the three-semester(20 months)experiment and observation,the measured values were analyzed by independent sample t-test,if necessary,using covariance analysis to verify;The evaluation selected the National Fitness Measurement Standards Manual(Children's Part)issued by the State Sports General Administration as the evaluation standard,and analyzed by chi-square test.Results:(1)Comparing the height mean values,the growth rate of the experimental group was significantly higher than that of the control group(P<0.01);the height-value covariance analysis,the pre-test height correlation probability P>0.05,and the Tianzu exercise intervention probability P<0.01.The weight gain of the experimental group was slightly smal er than that of the control group,but it was not significant(P>0.05).(2)The change of bone age level before and after the experiment showed that the decrease of the early development ratio of the experimental group was greater than that of the control group(P>0.05);the decrease of the late development ratio of the experimental group was also greater than that of the control group.The ratio of the decrease(P>0.05).(3)The height growth of the boys in the control group was slightly lower than that of the girls,while the height of the boys in the experimental group was slightly higher than that of the girls,but the difference was not statistically significant(P>0.05).The weight gain of the boys in the control group was slightly larger than that of the girls.Similarly,the difference was not statistically significant(P>0.05);the growth rate of girls in the control group was lower than that of boys,the difference was not statistically significant(P>0.05),while the growth rate of girls in the experimental group was also lower than that of bo ys,but the difference was the same.Statistically significant(P <0.01).Conclusions:1.Tianzu exercise can effectively promote the growth of preschool children.Tianzu exercise may have a certain effect on controlling the weight of young children.2.Tianzu exercise may make the development of bone age of children more reasonable.It not only inhibits early development,but also increases growth potential while promoting a slightly backward bone age development.3.The influence of Tianzu exercise on the height of boys may be slightly larger than that of girls;the effect on the weight of boys and girls is basically the same;the promotion of bone age development of boys is greater than that of girls.
