공군 사관생도의 복합운동에 따른 신체조성, 하지 근기능 변화 연구

Abstract

Objectives The purpose of this study is to analyze the difference in body composition and lower extremity muscle function according to the body fat percentage level of air force cadets, and to provide basic data for body composition management, improvement of lower extremity muscle function, and injury prevention. Methods Groups were set according to body fat percentage for 20 first-year cadets, and 18 students were selected as final subjects, excluding 2 cadets who could not attend due to injury or other reasons. Compound exercise was performed for 8 weeks, and body composition and lower extremity muscle function tests were measured in the pre- and post-test. Results In body composition, there were significant differences in body weight, BMI, and body fat percentage in the borderline body fat (HB) group. In the lower extremity muscle function, there were significant differences only in the LB (low body fat) group in the muscular strength (right extensor) and the HB (borderline body fat) group in muscle endurance (right extensor). Conclusions The 8-week compound exercise showed positive results in the body composition of the cadets, and it can be seen as an effective exercise for the body composition. In future research, it is judged that a greater effect can be expected if the exercise load setting and exercise period are extended to more than 8 weeks and various exercise programs are applied.
