Resumo

Redução de tecido adiposo e aumento de massa magra se constituem como objetivos frequentes em programas de exercícios voltados à saúde e à estética. Nesse contexto, ao se postular a necessidade de déficit energético para o emagrecimento e superavit calórico para a hipertrofia muscular, desenvolveu-se a ideia de que não seria possível a existência de ambos os fenômenos de forma simultânea. Contrariamente, emerge na literatura o termo “Recomposição Corporal” (RC), fenômeno no qual ocorre emagrecimento e hipertrofia muscular ao mesmo tempo. A RC já foi observada com emprego de diferentes técnicas de análise da composição corporal, desde métodos duplamente indiretos até ressonância nuclear magnética, e em diversos grupos populacionais, a saber: adolescentes, adultos sedentários ou fisicamente ativos, idosos e pessoas com excesso de peso, além de praticantes de modalidades esportivas, inclusive fisiculturismo. A RC ocorre com ajuste nutricional preciso, com consumo de proteínas acima da ingestão diária recomendada (0,8 g/kg), em faixas entre 2,4 e 3,4 g/kg de massa corporal/dia. Diferentes tipos de exercícios físicos podem conduzir à RC, desde o treinamento de força, passando pelo treinamento em circuito em alta intensidade, treinamento intervalado de alta intensidade e, inclusive, treinamento concorrente – na maioria das vezes com elevada frequência semanal.
