Study On The Relationship Between Physical Activity And Physical Health Of Primary And Middle School Students In Shanghai

In recent years,with the rapid development of modern Chinese society and economy,more convenient and quick way of life in people's lives are increasingly common,"physical activity" in the study life away,makes our country teenagers crowd languid is lazy way of life and the overweight obesity health,let young people lost guarantee basic physical health.For primary and middle school students in China in recent years speed,endurance,explosive force,flexibility and lung capacity reduced system of physical quality and health indicators,such as change the central committee of the communist party of China in 2006 the state council issued "about strengthening youth sports to enhance teenagers' opinions",the Shanghai municipal bureau of education to "big recess and sports garden construction" as the carrier,to the world health organization(who)issued by the primary and secondary school students daily physical activity is recommended for theoretical support,and of the primary and secondary schools in the district of Shanghai in the campus of an hour "sunshine sports" sports activities,to let all students can complete the high strength of 1 hour daily physical activity.Purpose: To study the physical activity of middle and middle school students during the one-hour implementation of sunshine sports,and to explore their contribution to the daily high-intensity physical activity.To investigate the distribution of high intensity physical activity of middle and primary school students in Shanghai;To explore the relationship between daily physical activity and physical health of primary and middle school students in Shanghai.Methods: This study selected the from Shanghai city center and suburban area and suburban districts of three primary schools and three middle school a total of 720 students as experimental subjects,by issuing ActiGraph GT3 X let all participants wear 7 days,including five school day and two days over the weekend,get students to school day on physical activity and physical activity outside the weekend day,at the same time distribution of physical activity log book,a student to record the daily physical activity time,physical activity and the content of the accelerometer to remove and wear time.In this study,multiple linear regression analysis was used to test the relationship between physical activity level and physical health(P<0.05).Results:(1)Among the participants of grade four boys,its MVPA sunlight sports activities on campus in time is 22.1±5.8 minutes,accounts for 35% of the sunlight sports time and overall school day school MVPA time 78%;Among the girls in the fourth grade,their MVPA was 17.2 ± 4.1 minutes in the sunshine sports activities on campus,accounting for 27% of the time of sunshine sports activities and 81% of the total MVPA time in the school day.Among the subjects of eighth-grade boy,its MVPA sunlight sports activities on campus in time for 17.7±4.7 minutes,28% of the sunlight sports activities time and overall school day school MVPA time 70%;Among the eighth grade girls,MVPA had 14.3±2.8 minutes of sunshine sports activities on campus,which accounted for 23% of the time of sunshine sports activities and 82% of the total MVPA time on school day.(2)Only about 18% of the grade four boys and 14% of fourth-grade girls and 12% of boys and 8% of eighth grade eight graders for the daily campus "sunshine sports for an hour of physical activity is recommended.(3)The average daily MVPA in the fourth grade was 27.2± 16.7 minutes,while the average daily MVPA was 12.8±4.2 minutes.In the eighth grade,the average daily MVPA time was 24.2±7.9 minutes,and the average daily MVPA was 12.3±4.7 minutes.(4)In the fourth grade,60% of MVPA in the MVPA was from the school;Among eighth graders,63% of the MVPA on school day came from school.(5)there was a significant negative correlation between the LPA and the overall score of the girls in the fourth grade(P<0.05).There was a significant positive correlation between the VPA and the overall score of the grade 8 boys and girls(P<0.05).Conclusions: This study concluded,the Shanghai city center and suburban area and suburban districts to participate in the subjects of fourth and eighth graders of daily physical activity level is low,especially every MVPA,met WHO less adolescent physical activity recommended daily amount of students;Shanghai primary and middle school students daily MVPA one hour sunlight sports activities mainly from the campus,campus sunlight sports activities to carry out the strength and time is not enough,the sunlight sports activities in MVPA ratio is low,the weekend of physical activity compared with the school day on physical activity is low.Whether boys or girls,senior or junior students,the physical activity of the school is higher than that of physical activity outside the school.The daily physical activity level of Shanghai primary and middle school students is correlated with body shape,physical fitness,body function and other physical health indicators.The correlation between higher intensity physical activity and physical health was most significant.
