Research On The Relationship Between Undergraduate' BMI And The Body Health In Jiangxi Province

To make sure the influence of body shape on physiological function and physical quality,insure the research of Jiangxi province university students' health to constitute a theory,this paper analyzes the data of college students' physical health survey in Jiangxi province.And use the method of documentary,interview investigation method,statistical analysis method,to analyze the current situation of college students body shape in Jiangxi province,and using body mass index(BMI)as a measure to explore the influence of student body shape and body function and the relationship between each index.According to the current college students' physical health overall sharp decline phenomenon,from physical exercise,diet,lifestyle and other aspects of scientific fitness,improve health,enhance physical fitness advice.The results are as follows:1.The BMI of college students in Jiangxi province maintained in the normal range,the frequency distribution histogram was "fine tail",indicate that a certain proportion of students beyond normal levels or belong to the scope of malnutrition.On the whole,the BMI of female college students in Jiangxi province accounts for the majority of the number of thin range,the number of male college students in the overweight range accounts for the majority.2.Jiangxi province university students' performance in vital capacity weight index was bad,male college students scores higher than female students,male and female college students' vital capacity and BMI values are positively correlated,while the vital capacity weight index and there was a negative correlation between BMI.3.Jiangxi province university students' poor performance in the 1000 m /800 m that do not pass the number accounted for 37.5% of the total,male and female college students of1000 meters /800 meters scores were positively correlated with BMI relationship,BMI in the normal range of the students,1000 meters /800 meters scores decreased significantly.4.Jiangxi province college male student's performance in the chinning is poor,most of them belongs to grade D.Male and female college students pull-up / sit up scores and BMI were negatively correlated to body weight,student who BMI beyond the normal range significant decline.5.Jiangxi province college student's standing long jump performance is normal,the majority concentrated in the pass range,excellent proportion of male and female students was low,standing long jump and BMI value were negatively related to the femalestudents,mild obesity group is higher than other group.6.The Jiangxi province university student run 50 meters the largest number of students failing grades,agile quality and lower limb muscle explosive force is poor,the female college students do not pass the number accounted for the total number of 64.75%girls,boys than girls scores overall male and female college students in the 50 meter race and BMI values were negatively related,student achievement beyond the normal range of apparent weight drop.7.The general situation of Jiangxi province university student's “sit and reach” has good results and concentrated distribution,female student's score better than male students,male students and excellent higher proportion of small fluctuations,there was a negative correlation between BMI and test results,including male university student's have high correlation.Conclusion:1.The quality of endurance and body mass index has relevance,obesity,both for the students aerobic exercise capacity or have a negative impact on pulmonary ventilation,pulmonary ventilation capacity,overweight or underweight students than students of normal weight in the endurance level.2.Strength quality and body mass index with high correlation,while high weight students are higher than the weight of students in absolute muscle strength,but the relative muscle strength and body mass index was negatively correlated to.3.Speed quality and body mass index also has relevance.The higher the weight of the students is far better than the lighter weight and normal weight students in the agile quality test items show results.4.The low correlation between flexibility and the body mass index,the boys of flexibility and body mass index correlation higher than girls,but the quality of flexibility is largely depends on the physiological form of congenital and acquired,whether targeted training.
