A Comparative Study Of Three Methods Of Agility Test For Age 7-20

Sensitive quality is an indispensable physical ability for human survival activities.Good sensitivity helps to master technical movements faster,and complete technical movements faster,more accurately and more coordinately.In high-level sports competitions,the quality of sensitivity directly affects the performance of athletes.There is a lack of research on sensitive quality in China.There is no detailed research on the differences of students'sensitive quality development.There is no relatively uniform standard for sensitive quality development curve and sensitive period,and there is little research on the comparison of sensitive quality testing methods.In this paper,literature review,test and mathematical statistics are used to test the7-20-year-old students in Guangzhou.The total number of students tested is 992,505boys and 487 girls.Illinois test,t-test and hexagon test are used as the test methods.To explore the age factors of male and female students,and how the results of the three sensitivity tests differ.This paper sums up the law of the development of sensitive quality of male and female students,and calculates the sensitive period of three testing methods by using the conversion formula of sensitive period of sensitive quality.This paper analyzes the correlation of sensitivity testing methods,discusses the common relationship of testing methods,and discusses the degree of common components in the three testing methods.Through the research of this paper,I hope to deepen the research on the sensitive quality of young people,understand the law of the development of sensitive quality,and have reference value for human body training and physical education teaching.To explore the core components of sensitive quality,to deepen the understanding of sensitive quality,to study the correlation of sensitive quality testing methods,to analyze the relationship between the three testing methods,to provide a basis for the evaluation of sensitive quality in physical education teaching.Through data analysis,the results of the Illinois test show that there is no significant difference between boys and girls at the age of 7,9 and 12(P>0.05),and there is no significant difference between boys and girls at the age of 8,9,10,14 and17(P>0.05),and there is no significant difference between boys and girls at the age of8,9,10,14 and 17(P>0.05),while there is only significant difference between boys and girls at the age of 9 and 10 in the hexagon test There was no significant difference in other age groups(P<0.05).The sensitive period of boys in Illinois test is 9-10 and15-16 years old,while girls only have 15-16 years old;the sensitive period of boys in t-test is 7-8 and 17-18 years old,girls are 7-8 years old;the sensitive period of boys in hexagon test is 9-10 and 10-11 years old,girls are 8-9 and 12-13 years old.There were significant correlations among the three sensitivity test methods.In the male group,the Illinois test and the t-word test were moderately correlated(r=0.501),the common variance R~2=0.251,the t-word test and the hexagon test were also moderately correlated(r=0.503),R~2=0.253,the Illinois test and the hexagon test were low correlated(r=0.473),and the common variance R~2=0.223 Female group:the relationship between the Illinois test and hexagon test,t-word test and hexagon test was moderate(r=0.518,R~2=0.268,r=0.518,R2=0.268),while the relationship between the Illinois test and t-word test was low(r=0.356,R~2=0.126).According to the correlation analysis of different age groups,the three test methods have different correlation performance.Conclusion:(1)There is a significant difference in the sensitivity of 7-20-year-old male and female students.The age group with significant difference was the most in Illinois test,and the age group with significant difference in hexagon was the least.Illinois test sensitivity is the most reasonable.(2)The sensitivity of 7-20-year-old male and female students increases with their age,but their performance declines in middle school.There are differences in the sensitivity period between the three sensitivity testing methods and other testing methods.The sensitivity period of sensitivity is mainly concentrated in primary school.(3)There is a significant correlation among the three sensitivity testing methods,but the correlation coefficient is not high,showing a low,medium correlation.The common variance of the three test methods is 50%lower than that of the others.
