The Correlation Between Body Mass Index and Physical Ability of College Students
In order to promote the physical health of college students,uni-variate analysis of variance,bina-ry logistic regression analysis,linear regression and other research methods were used to study the relation-ship between body mass index and physical fitness of college students.The results showed that the PFI(Phys-ical fitness index)values of the underweight group,the normal weight group,the super-weight group and the obese group were 0.15,1.08,-0.45 and-2.47,respectively,and the PFI values of the female group were 0.34,0.23,-0.45 and-1.41,respectively.The difference of PFI values among different body mass index groups was statistically significant(P<0.05),except for the underweight group of male students,the super-weight group and the underweight group of female students.The probability of underweight,normal weight and high PFI in male and female students was 1.54～8.04 times higher than that in obese group,P<0.05.The conclusion is that the relationship between PFI and BMI-Z of male students and the overall PFI shows a parabolic trend,while female students show a J-shaped trend.The proportion of high physical fitness of col-lege students in male and female students and the overall obese group was the lowest among the four groups,and college students in the obese group showed the lowest physical fitness status.The physical fitness status of male students in the normal weight group was the highest,but the physical fitness status of female stu-dents showed a different trend,and the physical fitness status of female students in the lean group was bet-ter than that of normal weight group,overweight and obese group.
