Meta-analysis Of The Effect Of Physical Exercise On Health State Of Middle School Students

As an important part of national physical health, health status of adolescentsreflects comprehensive strength, economic level and educational level of a country.The physical health status of middle school students not only directly affects theirstudy and life at the current stage, but produces long-term effects on their physicallevel, health situation and working abilities in their adulthood. Therefore, to seizethis important period of life has a positive and profound impact on their physicalgrowth, enhancing physical fitness.The research, adopting Review manager5.0software, conducts Meta-analysison literature of the recent decade which records the influence of exercises onphysical health status of middle school students. After screening the literature inaccordance with a uniform standard, the research ultimately determines to docomparative study between the groups before and after experiments in selectedaspects of height, weight, vital capacity, the Harvard step test index,50meter dash,800m (female),1000m (male), standing long jump, and other indicators of Sit andReach.The results are as follows:The numbers of the research about the effect of physical intervention on themiddle school students’ physical heath are increasing in1979-2012, but the quality islow. It reflects the scholars attach more importance to this field, but the ability isneeded to improve.There was no significant change between Chinese high school boys’ and girls’height and weight which intervened by sports in body patterning. However, in aspectof body function, a significant change was showed between Chinese high schoolboys’ and girls’ vital capacity and the Harvard step test index. There was a significantchange between Chinese high school boys’ and girls’50meter dash,800m (female),1000m (male) and standing long jump which intervened by sports, showing sportspractice is good to body speed quality, endurance and power quality, respectively.For indicators of Sit and Reach, no significant change was showed in boys which was opposite to that of girls.The research results of Meta-analysis and RevMan software will increasestatistical power, save research expenditure, improve the demonstration strengthand analysis different research results’ differences to make the conclusion moreexactly. It also can solve which the problem independent study could not settle andlead to a new problem. This software could deal abundant of documents and be notlimited by study numbers, it also could find out the flaw of the document and putforward a more objective, exactly and economic result than literature review. Inconclusion, this method and software will take a higher feasibility to study on sportsintervention．...
