| Abstract |
The purpose of this study was to evaluate the body composition(body weight, %body fat, WHR, BMI), pulmonary function(FVC), and physical fitness(grip strength, sit-up, VO2max, sergeant jump, side step, and sit and reach) in sedentary office worker by exercise. Subjects of this study were 119 males who are working sedentary behavior for over 6 hours/day. They were divided into 2 groups such as exercise group(n=65) and non-exercise group(n=54). Exercise group has been conduct aerobic exercise on 30mins/day and 3times/week for over 3 months. The date was analyzed by using descriptive statistics, independent t-test and correlation analysis. There were significant difference in weight(p<.05), %body fat(p<.001), WHR(p<.001), BMI(p<.001), FVC(p<.01), sit-up(p<.05), and VO2max(p<.05) between exercise and non-exercise group. In correlation analysis, there were negatively associated with weight(p<.05), %body fat(p<.001), WHR(p<.01) and BMI(p<.01), and positively associated with FVC(p<.01), situp(p<.05), and VO2max(p<.05) by exercise. Sedentary office worker had higher body composition, and lower pulmonary function and physical fitness than same age’s adult. There were significant differences in body composition, pulmonary function, and physical fitness between exercise and control group. Exercise group had different body composition, pulmonary function, and physical fitness from same age’s adult because of longtime sedentary life in office. Therefore, sedentary office workers need effective level of regular aerobic and resistance exercise to get balance of body composition and improvement of stabilization of musculoskeletal system. |
