Aeróbico e definição muscular, ele é fundamental?

Tendo em vista o treinamento de muitos fisiculturistas, diversas pessoas acreditam que somente com a implementação de exercícios aeróbicos é que irão conseguir bons resultados em termos de definição muscular.

Quem gosta de bodybuilding, com certeza já viu vídeos dos mais variados atletas fazendo exercício aeróbicos de baixa intensidade, para melhorar seus níveis de definição muscular.

Isso porque, estes exercícios tecnicamente, aumentam a lipólise (quebra de gordura). Como a maioria das pessoas tendem a copiar isso, sem observar o contexto, muitas vezes acham que somente isso basta para a melhora da definição muscular.

Basicamente, temos que entender alguns mecanismos, antes de definir se o aeróbico é bom ou não para a definição muscular.

Primeiramente, precisamos ter em mente que este processo é bastante similar ao de emagrecimento, já que o objetivo é a redução do percentual de gordura.

A diferença primordial, é que as pessoas que buscam a definição muscular têm (ou deveriam ter), músculos hipertrofiados, já que o objetivo é aumentar o “desenho” das linhas musculares.

Este contexto, muda bastante o cenário e a aplicação do aeróbico. Para ficar mais claro, vou explicar um pouco mais sobre a lipólise!

Aeróbico e definição muscular, existe necessidade?

Para que ocorra a definição muscular, precisamos aumentar a utilização da gordura como fonte energética. Isso é unanimidade.

Esta utilização de gordura acontece apenas de uma maneira, através do metabolismo aeróbico.

Assim, as moléculas de gordura se desprendem das células adiposas e são metabolizadas nas mitocôndrias, que são pequenas organelas, responsáveis pelo metabolismo aeróbico.

Você pode fazer de tudo, mas se sua dieta não for pensada para este objetivo, dificilmente conseguirá resultados palpáveis.

Resumindo, o aeróbico pode sim ser uma excelente maneira de melhorar sua definição muscular, mas como ferramenta auxiliar, inserida dentro de um contexto específico.

Além disso, a questão das cargas, intensidade e duração, precisam ser prescritas por um bom profissional. Bons treinos!
