Correlation between Body Mass Index and Physical Function and Fitness in College Students

Abstract

Using a test method and mathematical analysis, the correlation between BMI and physical function and fitness of college students was analyzed, as a basis for maintaining appropriate weight and improving physical function and fitness among college students. The results: (1) BMI of college students generally had a normal distribution with a left-hand peak and a right-hand slow tail. There was no significant difference in the proportion of males and females in the normal BMI level. (2) A highly significant positive correlation was found between BMI grade distribution and physical function (P<0.01), and gender differences were minimal. (3) Standing long jump performance was strongly correlated with BMI (P<0.01). The best scores were all at normal weight. (4) The correlation between body mass index and sitting and reaching performance was not significant (P>0.05). (5) In boys, there was a highly significant negative correlation between pull-up performance and body mass index (P<0.01), and the best performance was found in the normal weight range. Among girls, there was a negative correlation between 1 minute sit-up performance and body mass index (0.01<P<=0.05), with the lowest weight group showing the best performance. (6) In the 50m running test, BMI was significantly correlated with body mass index of college students (P<0.05), and the normal grade test score was the highest. (7) Boys’ BMI and 1000m running test scores showed a highly significant positive correlation (P<0.01), with the best performance occurring at low body weights. Results were found There was a significant positive correlation between BMI and 800m running test scores of girls (0.01<P<=0.05), and the best in the range of normal body weight. Normal-weight people had the best physical function and fitness, while obese people had the worst.
