A Study On The Relationship Between Physical Health And Physical Activity Of Primary And Middle School Students In Yangzhou City

In recent decades, students physical health tests have been carried out all over China and most of the surveys have shown that the morphological growth indexes such as body weight, chest circumference are ascending whereas the indexes such as lung capacity, speed and strength are descending and the incidence rate of all kinds of chronic diseases are showing a trend of increasing among the teenagers. Physical activity is one of the important factors influencing the physical health. Increasing physical activities can improve people’s physical health and prevent all kinds of chronic diseases. Adolescence is a key period of learning, however, students’long time of static activities and stressed academic entrance pressure lead to the severe decrease in their physical activity level. Taking the elementary and middle school students in Yangzhou city as the target students, this paper studies the correlation between physical health and physical activities and aims to provide theoretical basis for setting teenagers’physical activity standards in our nation, achieving the goal of improving the level of adolescent physical health as well.Taking the middle and primary school students’physical health status and physical activity in Yangzhou city as the research object, this research adopts document research, questionnaires, test, logical analysis, mathematical statistics and other research methods to analyze the correlation between physical health and physical activities of the primary and middle school students in Yangzhou city. Through analysis the author gets the following conclusion:(1)The correlation does exist between physical health and physical activities that the primary and middle school students in Yangzhou city had during traffic, leisure and learning activities. And appropriate physical labor has a positive impact on the physical health of the youth.(2)It is positive for the correlation between the time of traffic activity that the primary school students had and the indexes of height, weight, sit and reach, one minute sit-ups,50m.It is positive for the correlation between the time of traffic activity that the middle school students had and the indexes of height,50m;whereas, the correlation is negative between the time mentioned above and the indexes of weight, vital capacity, sit-ups,sit and reach. The increasing time of riding and the decreasing time of walking and cycling have some negative impact on physical health.(3) It is negative for the correlation between the time of leisure activity the primary school students had and the indexes of height, weight, sit and reach, one minute sit-ups; whereas, the correlation is positive between the time mentioned above and the indexes of50m. It is positive for the correlation between the time of leisure activity the middle school students had and the indexes of height, weight,50m;whereas. the correlation is negative between the time mentioned above and the indexes of lung capacity, stand ing long jump,sit and reach.Too much leisure activity damages the physical health in a certain degree that long time of watching TV and surfing the Internet have a bigger influence on primary and middle school students’physical quality and they are easily causing overweight and even obese.(4)There is a negative correlation between the time of learning activity the elementary school students had and the indexes of height, weight and one minute sit-ups, however, it is positively correlated with50m. Middle school students’learning time were positively correlated with height, weight and50m; negatively correlated with lung capacity.standing long jump, sit and reach. Learning activities is also one of the main factors influencing the physical health of primary and middle school students and too much time of learning activities will cause a decline in the primary and secondary school students’body function, therefore, it is necessary to cultivate students to form good living habits.(5)Students’time of sports activities in Yangzhou primary school is obviously and positively correlated with one minute sit-ups, but obviously and negatively correlated with weight,sit and reach. middle school is obviously and positively correlated with lung capacity, standing long jump, sit and reach,50m,800m,1000m, sit-ups and pull-ups, but obviously and negatively correlated with weight. Sports activity has a promoting effect to students’physical health which can improve all of the students’body functions, preventing various diseases. Decreasing time of physical activities reduces the level of primary and middle school students’ all kinds of body functions. Regular physical activities are beneficial to the improvement of cardiopulmonary function, flexibility, strength and other physical qualities. It can also consume excess body fat, preventing obesity and other chronic diseases. (6)The descending time of physical activities has become one of the important factors influencing the students’physical health. Adolescents should enhance their self physical activities, actively participate in a moderate amount of traffic, leisure, learning and physical activities, to develop a healthy lifestyle and promote the improvement of the level of physical health.
