The social development is human-oriented and the development speed is determined by men's integrated quality.People's physical condition is an important element in comprehensive national power.And above all,the middle school students' physical condition plays a critical role in national physical fitness.Based on the fact that the six years' stay in middle school is the most important stage at which students grow fast and athletic sports has great impact on their growth,the paper sets to investigate middle school students' physical fitness.Besides,Beijing,a typical area with advanced technology,economy and culture, always does the best in physical fitness testing with the most complete reported data and the most testees.However,by far no one has systematically investigated the physical fitness of Beijing middle school students.Therefore,this paper attempts to make a longitudinal comparison on the physical condition between the junior students in the first year and the senior students in the third year,in the hope of providing references for the inspection of students' physical fitness in other provinces.The 25000 testees include students from Junior Gradel to Senior Grade 3 in 12 middle schools of Beijing.After measuring their physique(height,weight) and testing their physical functions(vital capacity,step testing) and physical quality(50 Meter Run,boys' grip force, girls' sit-ups),the author arrives at the following conclusions:The index of students in Beijing Haidian District does not decrease rapidly.Compared with the result of nation-wide testing in 2005,this year's result is much better:First,Physique:In 2006,Beijing middle school students grow well in aspects of height and weight.Although some senior grade 1 male students are overweight,students in other grades weigh in the standard scope.Second,In 2006,heart and lung functions of middle school students in Beijing's Haidian District are generally good.The evaluation of vital capacity and the step test results in all grades shows that their heart and lung functions are above average.Third,Overall,the results of girls are better than those of boys.The senior grade 1 male students do best in grip test,Students in other grades can only pass the test.The standing long jump test results of the junior grade 3 and senior grade 1 male students are above average, and students in other grades also can only pass the test.Sit-up(for girls):The Sit-ups and standing long jump results of all the girls are good.Finally,Evaluation on the total score of physical fitness:In grading the total score,,there is no failure,which shows that the healthy condition is improving among Beijing middle school students.And among them,the schoolgirls' total score are graded fine.In addition,the junior 1 schoolboys' and the senior 3 schoolboys' score are also graded fine,while schoolboys in other grades are only regarded pass.Seeing from the testing result,the index of schoolgirls is lower than that of schoolboys;however,according to Criterion,the standard for schoolboys is higher than that for schoolgirls.
