This study aims to analyze the effects of steady participation in sport programs on changes in body composition and risk factors of a metabolic syndrome in obese middle-aged women participating in swimming and provide basic information to pursue healthy life in middle age. A 12-week swimming program was conducted with 157 women in 4 swimming centers located in G Metropolitan City. 1. For changes in health-related physical fitness by obesity classification, the moderate obesity group showed high changes in muscular strength, endurance, flexibility, and cardiovascular endurance and no significant differences were found in between-group test except the pre-test of endurance and the pre-test and post-test of flexibility. For changes in body composition, the mild obesity group had high changes in weight, BMI, and percent body fat, the overweight group had high changes in muscle mass, and the mild obesity group had high changes in percent body fat. All between-group pre-test and post-test had a statistically significant difference except muscle mass and percent body fat. 2. For changes in risk factors of a metabolic syndrome by obesity classification, the overweight group had high changes in diastolic blood pressure and HDL-cholesterol, the mild obesity group had high changes in triglyceride and systolic blood pressure, and the moderate obesity group had high changes in fasting blood sugar and waist circumference. All between-group pre-test and post-test had a statistically significant difference except the pre-test of systolic blood pressure, the post-test of fasting blood sugar, the pre-test and post-test of HDL-cholesterol. 3. For changes in health-related physical fitness by age, the age group over 51 showed high changes in muscular strength, endurance, flexibility, and cardiovascular endurance and no significant differences were found in pre-test and post-test except cardiovascular endurance. For changes in body composition, the age group under 40 had high changes in weight and percent body fat, the age group of 41-50 had high changes in muscle mass and W.H.R, and the age group over 51 had high changes in BMI. All between-group pre-test and post-test had a statistically significant difference except percent body fat. 4. For changes in risk factors of a metabolic syndrome by age, the age group under 40 had high changes in systolic blood pressure, the age group of 41-50 had high changes in diastolic blood pressure, fasting blood sugar, and waist circumference, and the age group over 51 had high changes in triglyceride and HDL-cholesterol fasting blood sugar. All between-group pre-test and post-test had a statistically significant difference except the pre-test and post-test of diastolic blood pressure and the pre-test of fasting blood sugar and waist circumference. Based on the results, higher obesity was associated with a decrease in weight, BMI, percent body fat, and WHR and an increase in muscle mass. For metabolic syndrome risk factors, triglyceride, blood pressure(diastolic, systolic), fasting blood sugar, and waist circumference were decreased and HDL-cholesterol was increased. As age was older, the same tendency as obesity was found. Middle-aged women steadily participating in a swimming program were decreased in health-related physical fitness factors and metabolic syndrome risk factors thanks to an increase in physical activity. Accordingly, it is considered that constant physical activity will greatly contribute to healthy life in middle age.
