Physical capacities and maximal fat oxidation rate
A GRAD test on a motorized treadmill determined the V’OBefore the start of the study, individuals were familiarized with the equipment and the procedures. All participants avoided strenuous exercise and maintained the same eating habits the day before the test and came to the laboratory after a 12-h fast.The GRAD test began with a 10-min rest period followed by walking in stages of a 5-min duration. According toThe V′OThe substrate oxidation rate was determined from V′OThe results of the graded exercise test were used to compute the relationship between substrate oxidation and exercise intensity, expressed as %V’O
