Research On The Physical Condition Of Students In Grade Four Of Primary School In Beijing

Constant is presented in full swing in the National Physical Education Teaching Reform in the field of "strengthening physical education and extracurricular exercise, promote physical and mental health of young people, a strong physique" reform idea. This is because only "youth is Guoqiang" youth only with strong body based, in order to promote the healthy development of the mental and psychological, so as to promote the absorption of cultural knowledge. This is not only the requirements of our country’s physical education teaching work, but also the requirements of the youth sports workers and the students themselves. Through the research on the physical ability test of grade four students in Beijing primary school, the specific situation and main problems of the physical development of primary school students in Beijing are obtained. To provide practical and feasible suggestions for different gender and living environment. To provide more clear and specific operational measures of the youth groups of the physical development of the specific content of building blocks, as well as first-line teachers’ teaching and education; making the primary school physical development sensitive period in the physical, in under the guidance of scientific and effective methods get foot length of the development, thus to the fundamentally improved students’ physical status.This article through the literature material law, the test method, the mathematical statistics method and the expert interview method, carries on the thorough and careful test research to the physical ability of grade four students in Primary School of Beijing, and through the comparison of the "national student’s physical health standard" in 2014, the conclusion is drawn:(1) four grade male and female students in Haidian District are in good shape, and the height and weight ratio are in excellent range.(2) the average score of the physical fitness of four male and female students in Haidian District is basically in good, and the passing range is not excellent. The physical qualities are still to be improved.(3) in addition to the quality of the speed, the rest of the physical quality of the girls are better than boys.(4) the physical quality of the students in rural schools is better than that of the urban students.From the test results can be found in the current situation and development of physical fitness of students and the positive and negative aspects of the problem,(1) four grade students whether boys or girls, or urban and rural school, in terms of height growth is not significantly different. So that the growth and development of male and female students in the four grade students are in the same growth stage. Under the same average height, the male body weight was significantly heavier than the girls, so the analysis of BMI value can be drawn boys’ BMI value is 19.06, the female is 17.39. That the physical development of students of grade four is good, and the BMI value is in excellent range.(2) in the quality of the speed, the boys’ performance is better than that of the girls, which is better than the girls’ speed. The speed quality of the boys in the countryside is better than the boys in urban areas. The reason is because of gender, boys and girls like sports, so boys’ performance will be better than girls. Control national physical health standards. The values of the four grades of male and female students are not up to the national health standards, and there is a great distance from the excellent standards, so it is very urgent to improve the speed of the students in grade four in Haidian District.(3) there is no obvious difference between the rural school and urban school in the flexible quality. However, there are significant differences in the flexibility of the girls and boys. The results showed that the score of 13.3 of the girls was significantly higher than that of the male 8.36. The main reason lies in the different physiological characteristics of male and female students. Girls generally better than boys in the quality of flexibility. But from the results of the average value of girls in a good range, while the boys only in the pass range. Are not up to standard.(4) there is no difference between men and women in terms of power quality. And there is no obvious difference between urban and rural school. Control of the national health standards, male and female generation results are within the range of good. There is still a certain distance from the rise of space. Sit ups is mainly reflected in the waist and abdominal strength, in practice can be through a variety of methods to improve lumbar muscle strength and body core strength.(5) in the aspect of sensitivity, the female students are obviously better than boys, but the quality of the students in the city school is lower than that in the countryside. The reason is the same as the difference between the flexibility and quality. Also due to physiological reasons, at this stage most of the girls’ sensitivity is better than the boys. And the reason that the students in the rural school is better than the students in the city school, it may be because of the different living environment. According to the national health standards, the mean of the girls in a good range, while the average boy in the pass, but did not reach the best range.(6) boys and girls, urban school students endurance performance indicators are better than the rural school students. And according to the national physical health standards can be seen, the four grade boys and girls are not up to the national physical fitness standards, all the girls in a good grade, urban boys’ endurance performance is good, while the rural boys only in the pass grade. Investigate its reason, may lie in the modern society, the students study pressure, the time of movement is less, which leads to the low performance of endurance performance.
