The purpose of this study was to investigate effects of 12 weeks of regular exercise on physical fitness and health-related variables in iron industrial workers. Thirty eight untrained volunteers that they who have a adult disease risk factor. All subjects participated to combined exercise program (weight training: 1RM 50-70%, 12-20 repetitions, 3-5sets, 30sec rest between each set, endurance exercise: RPE 15±2, 25min). Physical fitness (back strength, sit and reach, sit-ups, 1000m) and health-related index(weight, blood pressure, blood glucose, total cholesterol, HDL-c, LDL-c, triglyceride(TG), body fat, muscle mass, BMI) were measured before and after of the combined exercise program. Basal fitness was significantly difference that sit ups(P<.01), Health related variables were positive effect on blood glucose(P<.01), HDL-c(P<.01), LDL-c(P<.01), TG(P<.01), BMI(p<.05), and muscle mass(P<.01) improved significantly in pre and post. These result indicated that the regular exercise program of 12 weeks positive effects on physical fitness and health-related variables.
