Epidemiological studies show that the incidence of cardiovascular disease in women increases dramatically in the postmenopausal years. Lately, women have more longevity as compared to men and consequently the menopausal time is longer in comparison with the last decades. A number of factors can contribute to increased incidence of cardiovascular disease among postmenopausal women, including alterations in lipid profile, weight gain, and decreases in physical activity during the menopause. Therefore, the aim of this study is to verify whether long-term of exercise on the arterial blood pressure in postmenopausal women with eNOS gene G894T polymorphism could affect the response to aerobix exercise training. Our findings show that exercise training failed to modify Body mass index. On the other hand, women with eNOS gen with genotype GG were more responsive to aerobic training than those with GT+TT to lowering arterial blood pressure. In conclusion, our findings clearly show that the presence of polymorphism in the eNOS gen G894T is deleterious to blood pressure control in response to exercise training.
