Research On Optimization Of Young Students’ Physical Health Evaluation

In recent years, declining adolescent physical health level of students has become a global problem. The physical health condition of adolescent students in China is not optimistic. In such situation, it is nessesary to conduct scientific study on teenagers physical health evaluation index system, effective evaluation of the physical health level of the young students, and to find practical solutions to problems.Research purposes:based on the current adolescent physical health evaluation index as the research foundation, the paper proposed that the adolescent physical health evaluation in the new period should be related with the quality of health indicators test study, on body composition, aerobic capacity, muscle strength and endurance and joint flexibility, through testing methods to analyze the index of objectivity and applicability. It adopts experimental study to demonstrate the scientific nature and effectiveness of the indicators. It optimizes the young students physical health evaluation index to make scientific and accurate evaluation of adolescent health quality level, furthermore, to effectively improve the physical health problems. The paper put consideration of internationalization of evaluation index in order to further perfect our physical health of students evaluation standards and provide a reference.Research Methods:1. Literature review:the paper combed the adolescent physical health evaluation system research at home and abroad, analyzed the current adolescent physical health evaluation index of study dynamic.2. Physical measurement method:the paper chose the Chinese national students physical health standard and the United States FITNESSSGRAM health quality evaluation indexes in the test system.7～18Ughurs in Xin Jiang area young students were chosen as the research objects. Traditional indicators in strict accordance with the implementation of the requirements of the national students physical health standard "test analysis, FITNESSSGRAM evaluation indexes in the test system with reference to the latest FITNESSSGRAM reference guide (fifth edition) the implementation of the requirements of test and analysis.3. Experimental study:teens’ aerobic capacity evaluation index in the middle (1000m) boy800m/a girl a reverse layup,20meter Shuttle Run Test, bench test, Pearson product-moment correlation analysis is adopted to study and explore the scientific nature and effectiveness evaluation.The results of the study:1.The test results show that the evaluation index of body composition tests: height, weight, body mass index, omron constitution rate relatively comprehensive evaluation of the physical health of teenagers, as the growth of the age shows the characteristics of different development periods of physiological changes; American standard of skinfold method reflects the juvenile upper and lower body obesity. Aerobic capacity evaluation index test:a reverse layup20meter Shuttle Run Test in American standard and our country’s run (male and female1000m/800m) evaluation index reflects the teenagers change the physiological characteristics of different age stages of aerobic capacity. At the same time, for the elementary school higher grades stage of teenagers at a speed of400m running endurance tests; test results showed that10-12years old male and female400m run results were similar on the whole. American standard20meter Shuttle Run Test reverse layup and run in China (male and female1000m/800m), the test results show the boys achievement constantly rising with the increase of age, the girl with the increase of age grade stable rise, enter the scores after13years old to keep the development trend of relatively stable and slightly down. Muscle strength and muscular endurance evaluation indicators:grip strength, pull-ups/Modified pull-ups, sit-ups, standing long jump evaluation index better reflect on teenagers, the lower extremities and trunk muscle strength, choose the knees up in American Curl Up and Trunk Lift the test indicators show better effectiveness. Joint flexibility evaluation indicators:Back-saver sit-and-reach with Modified Back-saver sit-and-reach on the testing requirements of different so as to reflect the flexibility from different parts of the teenagers. Beautiful mark in Shoulder stretched better reflects the youth humeral back stretching and flexibility. From the Uighur adolescents overall test results of students’ health quality evaluation index, the physical health of urban and rural adolescents difference is more obvious; Choose beautiful mark test pass rate, according to Uighur adolescents on muscle strength and flexibility evaluation index of high pass rate, high school grade in aerobic capacity evaluation index in low pass rate, other grade pass rate is higher.2.The experimental results show that run (1000m) boy1000m/a girl with treadmill test values measured Vo2max relative negatively correlated (male r=0.216, female r=0.142).Calculated steps test of the Vo2max relative value relevance and treadmill testing for:boy r=0.497, p<0.01, girls r=0.413, p≤0.05or less, has significant correlation, from the perspective on the fitting coefficient m L=0.267, female L=0.188, the fitting degree is low, not with linear relation, can not accurately reflect aerobic stamina level of teenagers.20meter Shuttle Run Test calculated reverse layup and treadmill test Vo2max relative value relevance:male r=0.796, p<0.01, female r=0.748, p<0.01, has very significant correlation, fitting index of L=0.634, female L=0.599, fitting degree is high, and the linear relation is obvious. Therefore, choose a reverse layup20meter Shuttle Run Test as evaluation teenagers aerobic ability evaluation indexes more appropriate.Research conclusions:1.Promoting adolescent health quality evaluation is in line with the needs of the development and also conforms to the international trend of the development of adolescent physical health evaluation system.the internationalization of the evaluation index is highlighted.2.1t is objective and effective to use body composition, aerobic ability, muscle strength, muscular endurance and joint flexibility to reflect the development level of adolescent health quality. 3.As a common index of international youth aerobic capacity, middle-length run (male and female1000m/800m) reflects comprehensive quality level of the youth aerobic and anaerobic ability.A reverse layup20meter (Shuttle Run Test) effectively reflects the youth aerobic ability level, which can be a effective aerobic endurance evaluation index. Bench test cannot effectively reflect the youth aerobic ability level.
