PURPOSE: We developed a one-year exercise program based on evaluation of life style and physical fitness and investigated its efficacy. SUBJECTS AND METHODS: Sixty one Japanese males (30 < or = age < 59, body mass index: BMI > or = 26.4 kg/m2) were enrolled in the stady. The exercise program consisted of four sections: (1) Preparation for preventing injury; (2) Increase of daily activity; (3) Enjoying exercise; (4) Preparation and practice of individual-based on a exercise program. The subjects visited Okayama Southern Institute of Health and were being monitored weekly for one-year. They were instructed to check daily steps every day and increase daily walking to at least 1000 steps more than the daily walk at baseline. Before and after one-year follow up study, we evaluated life style and physical fitness in terms of body composition, aerobic exercise level, muscle strength and flexibility. RESULTS: The continuation rate for the program was 66%. Body weight (pre 81.5 +/- 7.4 kg vs post 78.6 +/- 7.3 kg), body fat percentage (pre 30.3 +/- 4.1% vs post 28.4 +/- 5.0%) and waist hip ratio (pre 0.95 +/- 0.04 vs post 0.92 +/- 0.04) were significantly reduced. Aerobic exercise level and muscle strength were increased. Regarding volition for exercise, execution, continuation and steps per day were also improved. CONCLUSION: Regular exercise at an institution (once a week) and change in daily life style may play critical role in reducing body weight. This new program proved quite useful for Japanese obese males.
