In this study, 1675 subjects (aged 18 to 60; 838 men and 837 women) were sampled randomly and tested. Using Futrex-5000I (Body fat and fitness Computer. Futrex, Inc. P.O. Box 2398 Gaithersburg, Maryland 20886), (l) based on input of age, gender, body weight, body frame (small, medium, and large), and height, fat(%), lean weight, and water were measured and (2) based on input age, gender, body weight, body frame, and exercise level (heavy, moderate, light, and other), appropriate weight, calorie intake/day, and calorie consumption in various exercise type. The results were summarized as follows' p<0.001). 1. Proportion of the body frame of men/women was 28.06%(470)/21.37%(358) of medium, 14.13%(235)/23.70%(397) of small, and 7.94%(133)/4.90%(82) of large. This uneven distribution may be caused by the heredity, environment, diet, exercise, age personal difference. 2. The fat(%) of men/women was 19.54±7.28/22.36±7.19 and the range of appropriate fat(%) of men/women was 6~15.71/9~21.53. Further more as age increases, fat(%) increases. 3. Amount of water of men/women was 62.42±5.31/58.59±4.73 and the calorie intake of men/women was 2518.91±224.91/2023.87±146.22. As age increases, those variables decrease. 4. After 10 minutes exercise, calorie consumption of men/women were different according to gender, age, body weight, activity level, exercise level, and personal difference. Correlations between body composition and exercise type were height and weight (r=0.56/r=0.42), fat and appropriate fat range (r=0.83/r=0.92), and calorie and jogging(r=0.54/r=0.66), and those were significantly high correlations (p<0.001).
