基于BMI分類的大學生體質健康狀況及其主要影響變量研究
[Abstract]:Based on the physique test data of sophomore students in a certain university in Shanxi Province, and referring to the specific range of physical health standards of college students in China, this study divided male and female students into light body reorganization (low weight), from the body mass index (body mass index,BMI). (normal weight), superrecombinant (over weight) in normal weight group and (obesity) in obese group. On the basis of classification, more than ten specific indexes of physical health status of male and female students were analyzed by cluster analysis of self-organizing mapping network (self-organization map,SOM) and visual principal component analysis (Principle component analysis,). The main variables and influencing factors of PCA) and the analysis of variance of order factors in each group are compared. The results show that the univariate ANOVA reveals the function and shape of different groups of male and female college students. The results of SOM cluster analysis revealed that boys' physique test indexes had a strong change rule under different BMI classification. The results of PCA analysis revealed that the main factors affecting BMI in all groups of male and female college students were restricted by the influence of body weight, and weight was the primary influence index of male and female students' physical health. It is also the main explanation factor of the current state of the sophomore students' physical health. The influence factors and the explanatory factors of the other groups are different and have some differences. The results also showed that the improvement of standing long jump results had a positive effect on the improvement of the physical health of male and female students in all groups. The improvement of vital capacity plays an important role in the improvement of boys' physical health, and the improvement of one-minute sit-ups is of great importance to the improvement of girls' physical health. It is suggested that we should strengthen the exercise intervention to the body weight, strengthen the physical activity dominated by anaerobic metabolism, strengthen the vital capacity exercise of boys and strengthen the one-minute sit-up exercise of girls. Through the data analysis and the result research, it provides the constructive suggestion for the university students to carry on the scientific and effective exercise, how to strengthen the physical education curriculum construction, and how to formulate the national standard.
