Study On The Construction Index System Of Physical Activity Behavior Of Junior High School Students Under The View Of Sports Literacy

The reality shows that,with the evolution of society and the improvement of the degree of civilization,the decline of human physical activity has reached a very dangerous edge.People,the law of living by exercise and abandoning the exercise and cause disease once again sounded the alarm to mankind.The systematic decline of physical health caused by lack of physical activity is like the "Damocles Sword" hanging on people's head,which makes human beings in "dangerous evolution".This important issue has aroused the high concern of the international community and our government.It has become a major proposition for the healthy development of human beings.In this paper,the specific performance of physical activity by the observation and interview of junior high school students as the breakthrough point,to improve the evaluation system of physical activity behavior of junior high school students in Jiangsu Province,on the basis of the rich research results of sports literacy,attempt to apply comparison method and Delphi method to construct junior middle school students' physical activity behavior index system under the perspective of sports literacy,aiming to provide some references and references for relevant departments to evaluate students' physical activity.Research results:preliminary constructed the index system of physical activity behavior of junior high school students under the view of sports literacy:first-level indicators for four dimensions,that is physical activity consciousness,physical activity skills and physical activity behavior;Secondary index eight dimensions,that is physical activity cognition,physical activity interest,physical activity attitude,basic activity ability,health fitness,sports skills,housework,traffic travel,physical exercise and leisure activities;35 main observation point.The results of the two rounds of Delphi method show that:Importance coefficient of experts all greater than 0.70,the mean all greater than 3,the coefficient of variation between0.00-0.28,Kendall concordance coefficient between 0.195-0.544,expert coordination coefficient achieves significant difference(P 0.05)or less.The above data are both in the scope permitted by the Delphi method,and the selected indicators is scientific.
