Relationship Between Body Composition, Physical Fitness, and Blood Variables in ELEMENTARY SCHOOL GIRLS

Abstract

The purpose of this study was to investigate the effect of exercise program application and the relationship between physical fitness factors and blood variables according to various obesity evaluation criteria for 73 elementary school girls in D-city. As a result of study, body fat percentage and BMI significantly(p<0.05) decreased after exercise program application. In the case of physical fitness factors, it was found that the right, left, and upper body strength, long jump, and physical efficiency index were significantly(p<0.05) increased. In the case of blood variables, insulin, GOT, and GPT significantly(p<0.05) increased, and glucose and HDL-cholesterol significantly(p<0.05) decreased. As a result of the correlation analysis between body composition-related indicators and physical fitness factors, body fat percentage, BMI, WC, WHR, and WHtR showed significant(p<0.05) correlation with back muscle strength, and BMI, WC, WHR, and WHtR had significant(p<0.05) correlations between right and left grip strength. The body fat percentage showed a significant(p<0.05) inverse correlation with sit-up, standing long jump, and physical efficiency index, and BMI showed a significant (p<0.05) correlation with sit and reach, and a significant(p<0.05) inverse correlation with standing long jump and physical efficiency index. WHtR showed significant(p<0.05) inverse correlation with in standing long jump. As a result of correlation analysis of body composition-related indicators and blood variables, body fat percentage, BMI, WC, WHR, and WHtR showed(p<0.05) significant correlation with blood insulin concentration and GPT. Body fat percentage and BMI showed a significant(p<0.05) correlation with triglycerides, and a significant(p<0.05) inverse correlation with GOT and HDL-cholesterol. WC showed a significant(p<0.05) correlation with triglycerides and a significant(p<0.05) inverse correlation with HDL-cholesterol. WHtR showed a significant(p<0.05) inverse correlation with HDL-cholesterol. When the results of this study were put together, the 12-week complex exercise program confirmed the positive improvement effect of physical composition and physical fitness factors of elementary school girls.
