Imagine que você precisa correr de um ponto A a um ponto B o mais rápido possível. Qual a velocidade máxima que você conseguiria manter? Agora imagine que você precisa levantar um peso. Um botijão de gás ou um móvel. Qual o peso máximo que você conseguiria levantar? Agora imagine essas mesmas situações onde no ponto B tem uma pessoa que você ama muito que está entre a vida e a morte esperando um remédio que está contigo no ponto A. Será que você não conseguiria um pouquinho mais do seu desempenho físico? Onde estava essa força? De onde saiu aquela resistência física? Quando falamos de efeito placebo no esporte estamos falando de mecanismos que podem dar um boost nas nossas capacidades físicas que destravam algumas reservas fisiológicas.
