*2.4. Basal Metabolic Rate (BMR), Body Mass Index (BMI), and Body Composition Assesment*

Volunteers height and weight were measured before the start the day of the race. Participants were also subjected to a body composition evaluation test (Tanita BC-780MA, Tanita Corp., Tokyo, Japan). The BMR is defined as the daily rate of energy metabolism an individual needs to sustain in order to preserve the integrity of vital functions. The BMR formula (BMR = Kg × 1 Kcal/h) was calculated based on previous studies [33].
