Abstract

Increased life expectancy of the elderly population is a worldwide phenomenon. In Brazil, the statistics show that this trend is occurring in a radical and very fast which increases the incidence and duration of menopausal women. However, menopause is associated with increased risk of several deleterious metabolic changes that may impair the quality of life. Studies indicate that women in this condition have reduced skeletal muscle mass and bone mineral mass, increased body fat deposition, changes in lipid profile, increased concentrations of inflammatory markers, reduced oxidative capacity, increased risk of developing insulin resistance and cardiovascular disease. These findings emphasize the importance of researching the effectiveness of non-pharmacological interventions to reverse this deleterious situation, since the hormone replacement therapy has resulted in increased risk of developing cancer. Thus, physical activity is indicated to mitigate these symptoms and the resistance training should be considered. Previous studies of our research group show that resistance training promotes positive remodeling of several tissues and minimizes some of the deleterious effects of estrogen reduction, both in humans and animals. The aim of this project is a better understanding of the molecular physiological mechanisms involved in the response to resistance training in the tissues: bone, skeletal muscle, liver, brain and cardiac in ovariectomized rats with and without hormone replacement therapy.
