Remodeling of the soleus muscle of ovariectomized old female rats submitted to resistance training and different diet intake.

Sarcopenia is a common condition that is associated mainly with hormonal factors, nutritional status, physical activity, leading to a lower quality of life. Thus, this study aimed to evaluate the effects of diets with vegetable or animal proteins (AP) associated with resistance training on the structure of the soleus muscle in aged Wistar rats. The histochemical technique was used for the typing of muscle fibers, the cross-sectional area of myocytes, and volume densities of myocytes and interstitium.

The Agita São Paulo Program as a model for using physical activity to promote health.

The "Agita São Paulo" Program applies a multilevel intervention approach to promoting physical activity among the 37 million inhabitants of the state of São Paulo, Brazil. The verb "agita" means to move the body, but the term also suggests changing the way of thinking and becoming a more active citizen. Since being launched in 1996, the Program has been widely copied throughout Brazil and in other countries of Latin America, and the World Health Organization has characterized it as a model for other developing countries.

Promotion of physical activity in a developing country: the Agita São Paulo experience.

The purpose of this paper is to present key points of an intervention programme (Agita São Paulo Program) to promote physical activity in a developing country. Agita is a multi-level, community-wide intervention designed to increase knowledge about the benefits and the level of physical activity in a mega-population of 34 million inhabitants of São Paulo State, Brazil. The main message was taken from the Centers for Disease Control/American College of Sports Medicine (CDC/ACSM) recommendation that: 'everyone should accumulate at least 30 minutes of physical activity, on most days of the weeks, of moderate intensity, in one single or in multiple sessions'.
