BMI Students In Jiangsu Province And The Correlation Function And Physical Characteristics Of Identity

Based on student physical health survey in2010in Jiangsu province under the age of18-22male and female college students in all kinds of data as the research object, using the literature material, interview survey method, statistical analysis and other methods, understanding the present situation of the college students body shape, and body mass index (BMI) as a measure of students form, explore students’ body shape and body function and physical quality the influence of the every index. And in view of the present college students’ physical health comprehensive sharp decline phenomenon, from the physical exercise, diet, lifestyle, etc, put forward scientific fitness, improve health, enhance physical fitness.Through statistical analysis, the results are as follows:1Boys BMI index and vital capacity weight is moderate negative correlation, BMI5-8correlation is greater than the BMI1-4; Girls are negatively related. The correlation of Girls BMI and Vital capacity index weight among different BMI grade segment is nearly.2Boys BMIis moderate negative correlation with grip, female BMI are negatively correlated with grip strength weight index, BMI level section of the correlation between the gaps is smaller.3The boy BMI are negatively correlated with pull-ups, BMI5correlation is greater than the BMI1-4-8; Girl’s BMI and sit-ups are negatively correlated, but the correlation coefficient between paragraphs is more close to.4Male and female BMI is negatively related to the endurance run result all are low, but the boys relevance than girls. BMI of different grade correlation is obviously different, BMI1-4, male and female BMI is associated with endurance run are not; BMI5-8, when male and female are positively correlated, but the boys than girls high correlation.5BMI values for both men and women are negatively correlated with50meters graded, but boys than girls’high relevancy. While in BMI1-4, men and women have very low correlation; BMI5-8, when boys are negatively related, girls have no related.6Between male and female BMI and standing long jump are negatively correlated, relevance than girls and boys. BMI1-4, the correlation is close to male and female; BMI5-8, the relevance of boys was obviously higher than that of girls.7Overall, the boy BMI is associated with"sit and reach" test no, girl has low positive correlation. BMI1-4, male and female both are low positive correlation; BMI5-8, the boy has a low negative correlation, girl, no related.Summarize the above results, the analysis and inference, get the following conclusion: 1Confirmed by BMI and WHR, most of the men and women in our province university students’ body form is in the normal range, but also about one third of the students is a healthy weight, men mainly for overweight and light weight, main performance for light weight and lighter weight.2Boys’BMI in body function indicators, and vital capacity index weight correlation in grip strength and body mass index were higher than girls, to moderate, girls are low. On the index of lung capacity weight index, boy fat shape correlation is higher than thin body size; the difference between different size smaller girls. On the grip BMI index, fat thin sizes have little difference between girls and boys.3Integrated the quality metrics, relevancy on BMI and body quality, more boys than girls, and a high BMI values corresponding to the correlation is higher. Boys along with the growth of the BMI growth brought about by the correlation is greater than the growth of girls4Integrated the quality metrics, relevancy on BMI and body quality, more boys than girls, and a high BMI values corresponding to the correlation is higher. Boys along with the growth of the BMI growth brought about by the correlation is greater than the growth of girls5As can be seen by the statistical results, the average best for mostly appeared in the BMI4level, maintain normal body shape so for male and female students is very necessary. But because of BMI and the objective correlation coefficient is not high, mostly this show again:for students’ health by only one normal size is not enough, to effectively strengthen physique by way of exercise, etc.Aimed at the problems existing in the current student physique monitoring, and Suggestions to reform some existing monitoring indicators and indicators of evaluation standard, implement the scientific nature of physique monitoring system. For students’ body form bad rate higher, body function decline, body quality retrogression phenomenon, in the reform of physical education curriculum structure, the abundant extracurricular sports way, realize the healthy and reasonable diet, the aspects such as building good habits, is improved.
