The effect of aerobic training and complementary of vitamin D + omega-3 on metabolic syndrome indices in obese women

Metabolic syndrome is a set of risk factors for cardiovascular disease and type 2 diabetes. Vitamin D plays an important role in the treatment and prevention of metabolic syndrome. The purpose of this study was to investigate the effect of aerobic training and complementary of vitamin D + omega-3 on metabolic syndrome indices in obese women.

In this quasi-experimental study 40 women (26/4±7/6 yrs. 32/26±1/78kg/m2 ) Volunteered and they were randomly divided into four groups of 10 persons (aerobic training, vitamin D + omega-3 supplements, aerobic training + vitamin D + omega-3 supplements and control groups) . Aerobic training consisted of 12 week, 3 sessions of 1 hour each session at 60% of maximal oxygen consumption (1.6 km of treadmill walking). In supplement groups, supplementation was performed daily with 1000 IU vitamin D and 1000 mg fish oil. Blood samples were taken before and after the research protocol. Data were analyzed using covariance analysis test.

12 weeks of aerobic training plus supplementation significantly reduced lipid profile, fasting blood glucose, insulin concentration, waist circumference and diastolic blood pressure and the maximum oxygen consumption was significantly increased (p≤0/05).

Aerobic training is a safe and effective way to improve metabolic health. Also, combining vitamin D and omega-3 fatty acids to modify metabolic syndrome-related indicators can increase the beneficial effects of training.
