Background: Regular exercise is known to be useful for health promotion and disease prevention. Especially, exercise has a beneficial impact on coronary artery disease, hypertension, diabetes mellitus, osteoporosis, obesity, mental health, cancer and other diseases. In spite of these influences of exercise, physicians do not spend their time to prescribe exercise, because they have not enough time during their busy practice. According to a study in U.S.A, four out of five patients have never been told by their physicians to exercise. So we performed this study to verify the effectiveness of brief exercise prescription to improve exercise performance. Methods: From June 1996 to August 1996, data were collected from hypertensive and diabetic patients who visited department of family medicine, Sang-Gye Paik Hospital. Case and control groups were randomized by table of random numbers Control group received structurized exercise prescription brochure only, and case group received brief exercise counseling from a physician with structurized exercise prescription brochure. One month later, we analysed the exercise performance rate between case and control group. Results: Total number of subjects were 138. 34 patients(24.6%) were male and 104 patients(75.4%) were female. Patients less than 30 years old were 7 patients(5.1%), 30-39 years old were 20 patients(14.5%), 40-49 years old were 25 patients(18.1%), 50-59 years old were 49 patients(35.5%) and over 60 years old were 37 patients(26.8%). 44 patients(61.1%) of case group and 44 patients(78.6%) of control group were performing exercise regularly. Exercise performance rate in female (71.4% in case group, 75% in control group) was higher than that in male(25% in case group, 44.4% in control group) . Exercise performance rate was the highest in patients between 50-59 years old in both case(40.9% ) and control group(50%). Conclusion: There were no increment in exercise performance rate in case group after brief exercise counseling by a physician with structurized exercise prescription brochure.
