WebThe crossover concept was first outlined by Brooks and Mercier1 to describe the relative balance between carbohydrate (CHO) and fat metabolism during sustained … WebIn Brief. This copy-and-share column provides practical information about the crossover concept. It has been observed since the early 1900s that exercise intensity influences the relative reliance on fats and carbohydrates for energy. In the mid-1990s, the term crossover concept was coined, and a new debate about its meaning emerged.
