abstract
Adipose tissue reduction and lean mass increase are frequent goals in exercise programs aimed at health and aesthetics. In this context, when postulating the need for an energy deficit for weight loss and a caloric surplus for muscle hypertrophy, was developed the idea that it would not be possible for both phenomena to exist simultaneously. Contrarily, the term “Body Recomposition” (BR) emerges in the literature, a phenomenon in which weight loss and muscle hypertrophy occur at the same time. BR has already been observed using different techniques for analyzing body composition, from doubly indirect methods to magnetic resonance imaging, and in different population groups, namely: adolescents, sedentary or physically active adults, the elderly and people with excess weight, as well as practitioners of sports, including bodybuilding. BR occurs with precise nutritional adjustment, with protein consumption above the recommended daily intake (0.8 g/kg), in ranges between 2.4 and 3.4 g/kg of body mass/day. Different types of exercises can lead to BR, from strength training, through high-intensity circuit training, high-intensity interval training, and even concurrent training – most often with a high weekly frequency.
