Study On The Correlation Between Bmi Level And Physical Health In Ningxia Normal University

As a special age group,college students are at a special stage of development.Therefore,college students' physical function level should be paid more attention in physical education.On the basis of reading related articles of BMI levels and physical health,this paper,adopting documentary method,physical testing,mathematical statistics method and other methods,makes a research on 1996 non-professional sports college students'(603 boys and 1393 girls)physical health in Ningxia Normal University.After stastication and analysis,this paper tries to explore college students' various body function,physical quality development and difference.On this basis,the body function and the similarity and speciality of the basic sports ability of college students at different BMI levels are studied.The results of the paper provides theoretical basis for relevant departments of Ningxia Normal University to improve physical exercise methods,enrich physical health teaching contents,and formulate policies and intervention measures.The research results show that:1.The proportion of BMI in Ningxia Normal University is 67.50%,but 32.50%of students have overweight and obesity and low weight.With gender as the influencing factor,the mean BMI was highly significant.The mean BMI of male students was higher than that of females.There was significant difference between BMI and gender.The difference between low weight group and group was the highest,and girls(28.30%)were higher than boys(17.90%).Regarding the national factors,there was no significant difference in the mean and grade of BMI.With the professional as the influencing factor,the BMI mean has a highly significant difference,Science > Art > Arts;BMI level has no significant difference.There was no significant difference in the mean BMI with grades as the influencing factors.However,the BMI grades had significant differences,and the proportion of obese groups was the largest.The number of obese groups was the highest,and the number of obesity increased with the grade.2.With gender as the influencing factor,the mean value of vital capacity has a highly significant difference,in which the average lung capacity of male students is higher than the average vital capacity of female students.Taking the professional asthe influencing factor,the mean value of vital capacity has significant difference,and the mean value of lung capacity of art students is higher than that of liberal arts.There was no significant difference in the mean lung capacity between the nationality and the grade.In terms of physical fitness indicators,there is no significant difference in the national 50 meters running and standing long jump.There is no significant difference in the sitting position of the sitting body in the profession.There was no significant difference in standing long jump and sitting position flexion at the grade level.There are significant or highly significant differences in the remaining influencing factors and physical indicators.3.Based on the different grades of BMI,the differences in physical function and physical fitness of the students were studied.The results of one-way analysis of variance showed that there was a highly significant difference between the BMI grade and the vital capacity of the bodily functions.The low-weight group was the lowest,and the obese group was the second.There is a highly significant difference between the BMI grade and the vital capacity and body mass index.The higher the BMI level,the lower the mean value of the lung capacity and body mass index,that is,the higher the lung capacity,the greater the body mass index,and the smaller the vice versa;the BMI grade and speed quality exist.Significant differences,the higher the BMI level,the worse the speed quality,the obese group is the worst in the speed quality;the BMI level has a highly significant difference with the standing long jump,the obese group has the worst explosive power;the BMI level and the sitting body flexion have Significant difference,the higher the BMI level,the smaller the mean value of the sitting body flexion,that is,the obese group has the worst flexibility;the BMI level has a height with one-minute sit-ups(female)and pull-ups(male)Significant differences reflect that the higher the BMI level,the lower the mean value of the indicators,that is,the worst quality of the obese group;BMI,etc.And 800 m run(female)and 1000 m run(M)also has a highly significant difference in performance with changes in BMI levels,reflecting the quality of endurance worst in obese group,overweight second.From the above research results,the following suggestions are given to the physical health promotion of Ningxia Normal University students: 1.The schoolclassifies students according to the BMI level,and classifies and trains according to different BMI levels.Different groups have targeted teaching or corresponding teaching.Training content.2.The family allows parents to fully understand the student's physical fitness test scores and BMI grades,so that parents can play a role in supervising students to improve their physical health.3.Students should establish correct aesthetic concepts,establish healthy sports habits,and lay the foundation for promoting the balanced development of various physical functions and physical qualities.
