This study evaluates the effect of different types of diets (high and normal protein) on lean and fat mass, and strength in postmenopausal women practitioners of resistance exercise. Two groups will be created: high protein (1.2 protein g/body mass/day) and normal protein (0.8 protein g/body mass/day). The same training will be performed for both groups.
Both groups will undergo the same training protocol, differing only on the protein content of the diet. The dietary assessment will be made through the 24-hour food recall, being conducted at the beginning, middle and end of the intervention. Resistance exercises for upper and lower limbs will be performed, at 70% of one repetition maximum. SPPB, tug, 6-minutes and 400 meters will be performed.

To observe the effect of a high protein (HP) diet over muscle mass, fat mass, and strength changes, focusing in differences between the NP and HP groups.
To observe the effect of a normal protein (NP) diet over muscle mass, fat mass, and strength changes
The physical strength training will be performed equally by both groups, containing exercises for upper and lower limbs and aiming for hypertrophy.
