사관생도의 BMI 수준별 전투관련 체력의 비교 연구

Abstract

The purpose of this study was to investigate the characteristic analysis of combat fitness according to BMI (body mass index) in military cadets. Subjects were divided into 3 groups [normal weight group(18.5~22.9 kg/㎡, n=100), over-weight group(23~24.9 kg/㎡, n=100), obesity group( 25 kg/㎡, n=100)] according to BMI levels. The data was analyzed by using descriptive statistics, one-way ANOVA, and Pearson correlation analysis. The results of our study are as follows: 1) Body composition variables showed significant differences in all variables except height among BMI groups. 2) The 3 km run was significantly faster in the normal weight group than in the obesity group. 3) The combat circuit training was significantly slower in the normal weight group than in the over-weight group and the obesity group. The leg tuck was significant was significantly higher in the normal weight group than in the obesity group. 4) In the normal weight group, push-up showed a significant negative correlation with body weight and body fat percentage, and 3 km run was positively associated BMI. In the over-weight group, body weight showed a significant negative correlation with push up and a significant positive correlation with 240 m shuttle run. And there was a significant negative correlation between muscle mass and combat circuit training, WHR (waist hip ratio) and 3 km run. In the obesity group, 3 km run and BMI showed a significant positive correlation, and body fat percentage showed a significant negative correlation with push-up and leg tuck. As a result, it was found that the appropriate BMI level of military cadets had a positive effect in the case of overweight(23~24.9 kg/㎡), and body fat percentage should also be considered in the case of obesity(25 kg/㎡).
