2.6. Indirect Calorimetry (SWRE)
The balance of energy substrates was calculated by indirect calorimetry during submaximal work-rate running exercise for 45 min (SWRE), performed after six hours of fasting, before and after the training period. The dietary restriction before the SWRE session aimed to prevent the oxidation of exogenous carbohydrates among the participants during the experimental sessions [LIPox and CHOox rates were determined in 5-min blocks along the SWRE (5 to 40 min) from the VO
