Introduction: The total daily energy expenditure is composed of the basal metabolic rate (BMR), the thermic effect of food (TEF) and the energy expenditure during physical activity, the latter being subdivided into the energy used specifically in exercise training and energy in activities not associated with exercise. BMR is understood as the "cost of living", that is, the energy cost of keeping all physiological processes active, cognitive alertness and sets the stage for all life activities. It comprises the caloric expenditure at rest and occupies approximately 2/3 of the total daily caloric expenditure. BMR varies between subjects and is proportional to weight, particularly muscle mass, body composition and energy imbalance.

Objective: To compare the basal metabolic rate of healthy adults, recreational athletes by indirect calorimetry and predictive formulas.

Methods: Non-experimental design study, with a quantitative approach, correlational scope with the objective of group comparison. 76 people with normal weight and overweight according to BMI were evaluated with indirect calorimetry.

Results: Significant differences were found when comparing the basal metabolic rate of recreational athletes by indirect calorimetry and predictive formulas proposed by Owen, Mifflin and Schofield, whereas no significant differences were found when comparing with the Harris-Benedict predictive formula.
