The purpose of this study is to analyze the level of obesity and sarcopenia among chronic obstructive pulmonary disease(COPD) patients in Korea. The current study recruited 75 patients with COPD who visited the department of respiratory medicine at J University Hospital in J-do. Height, body weight, waist circumference, and hip circumference were measured, and body composition, muscle strength, and flexibility were assessed. The levels of obesity were classified with body mass index(BMI), waist-hip circumference ratio(WHR) and percent body fat, and sarcopenia was classified with the value of skeletal muscle mass and muscle strength by Asian Working Group for Sarcopenia. In results, it was found that the level of obesity was very high as 43% by BMI, 88% by WHR, and 64% by percent body fat. The lower level of muscle strength was 15.50% in males and 23.50% in females. The lower level of muscle mass was 24.10% in males and .00% in females. Males who had one sarcopenia factors were 22.40%, and females were 23.50%, respectively. Males with sarcopenia were 6.90%, and females were .00%. In conclusion, regular resistance exercise is essential not only for the development of motor skills, but also for the normalization of skeletal muscle function and prevention of muscle dystrophy among COPD patients.
