Relative Fat Mass(RFM)의 구인 타당성 검증
문준배(Mun, Jun-Bae),조원제(Cho, Won-Je) 한국웰니스학회 2023 한국웰니스학회지 Vol.18 No.1
이 연구는 비만측정도구인 RFM를 BMI 및 허리둘레와 비교하여 심혈관질환 위험요인과의 구인 타당성을 검증하기 위해 실시하였다. 이 연구의 목적을 달성하기 위해 국민건강영양조사의 제8기 2차년도(2020년)의 원시자료를 사용하여 20세 이상의 성인 남녀 총 3,901명의 자료를 분석하였다. RFM의 구인타당성 검증을 위해 체질량지수와 허리둘레가 심혈관질환 위험요인(고혈압, 당뇨, 이상지질혈증)에 미치는 영향력을 분석하기 위해 SPSS Ver. 20 통계프로그램을 사용하여 로지스틱 회귀분석을 실시하였다. 그 결과 RFM은 심혈관질환 위험요인과의 피어슨 상관계수는 약함(r = .2)에서 중간(r = .4) 정도의 관계를 나타냈으며, 통계적으로 유의성을 보였고 대부분의 효과크기는 중간(medium, Cohen’s d = .40)에서 높음(large, Cohen’s d = .87) 수준을 나타냈다. 또한 비만 측정도구와 심혈관질환 위험요인의 유병률을 분석한 결과 통계적으로 유의하였고(odds ratio, OR = 1.71~4.09, 95% 신뢰구간 = 1.36~5.91), 대부분 그 효과크기는 작음(small, Cohen’s d = .30)에서 높음(large, Cohen’s d = .78) 수준을 나타냈다. 따라서 RFM은 체질량지수, 허리둘레에 비해 심혈관질환 위험요인의 유병률을 예측하는데 더 효과적인 비만측정도구로 사용될 수 있을 것이다. This study was conducted to verify the construct-related validity of cardiovascular disease risk factors by comparing the obesity measurement tool relative fac mass(RFM) with the body mass index(BMI) and waist circumference(WC). This study analyzed a total of 3,901 adult men and women aged 20 or older using raw data from the Korean National Health and Nutrition Examination Survey in 2020. To verify the construct-related validity of RFM, the effects of BMI and WC on hypertension, type 2 diabetes and dyslipidemia was analyzed. For the analysis, binary logistic regression analysis was performed using the SPSS Ver. 20 statistical program. As a result, the Pearson Correlation Coefficient of RFM and cardiovascular disease risk factors showed a relationship level between weak(r= .2) to moderate(r= .4) and it showed statistical significance. Also, most effect sizes showed medium(medium, Cohens d = .40) to large(large, Cohens d = .87) levels. In addition, as a result of analyzing the prevalence of obesity measurement tools and cardiovascular disease risk factors, it was statistically significant(odds ratio, OR = 1.71 to 4.09, 95% confidence interval = 1.36 to 5.91), and most effect sizes showed small(small, Cohens d = .30) to large(large, Cohens d = .78). Therefore, RFM is expected to be used as an obese measurement tool that is more effective in predicting the prevalence of cardiovascular disease risk factors than BMI and WC.

Soldiers are always required to improve and maintain their physical fitness. Thus, military conducts physical fitness tests periodically to evaluate soldiers" fitness level. The purpose of this study was to analyze the relationship between various methods of measuring cardiorespiratory endurance, and to provide an estimation equation and conversion table for comparison between each tests. Subjects of this study were 305 cadets who attended basic military training. Cardiorespiratory endurance was measured by 3km running, 1.5km(1.2km for women) running, and 20m SR(shuttle run) test. The results showed a significant correlation between them, and estimation equations were developed. In addition, a conversion table between the tests was provided for people who are not familiar with statistical methods. As the results of this study provide a useful tool comparing among cardiopulmonary endurance military and non-military data, this study could contribute to development of the related academic field.

5주간의 기초군사훈련 프로그램이 신체조성과 체력변화에 미치는 영향
이상원(Sang Won Lee),김지훈(Ji Hoon Kim),문준배(Jun Bae Mun) 한국사회체육학회 2011 한국사회체육학회지 Vol.0 No.44
To examine the effect of the 5-week-period Korea Military Academy (KMA) basic military training program on body composition and fitness, sixty four subjects (40 male and 24 female students) were selected from 245 freshmen randomly. The body composition were estimated by hand to foot Bio-electrical Impedance Analyzer (Inbody 720, Biospace Co, Korea), and 3 fitness tests of Army Physical Fitness Test (APFT) and 8 fitness tests of national fitness test were performed in the first and fifth week respectively. 13 subjects who did not incomplete both measurements were excluded from the analysis of data. As a result, 51 students (35 males and 16 females; 18.63±.48 years and 18.96±.62 years respectively) completed total measurement. All measurements were performed under control of expert with ACSM health and fitness instructor certification. As results of estimation of body composition, mean difference of weight, fat mass, and % body fat on male were significantly decreased (-3.75kg, -3.83kg, and -4.64% respectively), but mean of fat free mass was not significantly changed (+0.11kg). There was significant mean difference of weight, fat free mass, fat mass, and % body fat on female (-1.01kg, +2.74kg, -3.72kg, -5.58% respectively). Statistically significant improvement was revealed in 3000m run, sit-up (2 minutes), and push-up (2 minutes) test (9%, 27%, 25% for male and 14%, 37%, 60% for female respectively). In the eight national fitness tests, muscular strength and endurance, flexibility, and balance were increased significantly, but agility was not changed and muscular power was decreased significantly in male. Similar result was revealed in female group. Significant increase was showed in strength and muscular endurance, and balance, not in flexibility. Not significant change was revealed in agility and muscular power. In this study, the 5 weeks of KMA basic military training program had positive effect on improvement of body composition and fitness enough to adapt themselves to severe cadet life. Especially muscular strength and endurance were improved outstandingly compared to other fitness components. However, extra complementary training program for muscular power and agility are needed in future to accomplish balanced improvement of fitness components for cadets to perform various military missions.
