Reference values for cardiopulmonary exercise testing for sedentary and active men and women.

BACKGROUND The reference values for cardiopulmonary exercise testing (CPET) available in Brazil were derived from a cycle ergometer in a sedentary and relatively small population. OBJECTIVE Provide reference values for CPET in Brazilians of both sexes, either sedentary or active. METHODS From 2006 to 2008, 3,992 CEPT of healthy individuals were selected from our laboratory. Athletes, smokers, patients with any known pathology, users of continuous medication and obese patients were excluded. Peak VO(2) was considered max VO(2). We also analyzed the anaerobic threshold VO(2), maximum ventilation and oxygen pulse according to sex, age, sedentary and active patients. Age groups were divided as follows: G1 (15-24), G2 (25-34), G3 (35-44), G4 (45-54), G5 (55-64) and G6 (65-74). RESULTS According to age groups, the mean values of VO(2) in ml/kg/min with their standard deviations were: Active man: G1-50.6 ± 7.3, G2-47, 4 ± 7.4, G3-45, 4 ± 6.8, G4-40.5 ± 6.5; G5-35.3 ± 6.2; G6-30.0 ± 6.1. Active woman: G1-38.9 ± 5.7; G2-38.1 ± 6.6; G3-34.9 ± 5.9; G4-31.1 ± 5.4; G5-28.6 ± 6.1; G6-25.1 ± 4.4. Sedentary man: G1-47.4 ± 7.9; G2-41.9 ± 7.2; G3-39.0 ± 6.8; G4-35.6 ± 7.7; G5-30.0 ± 6.3; G6-23.1 ± 6.3. Sedentary woman: G1-35.6 ± 5.7; G2-34.0 ± 4.8; G3-30.0 ± 5.4; G4-27.2 ± 5.0; G5-23.9 ± 4.2; G6-21.2 ± 3.4. CONCLUSION This article provides reference values of max VO(2), among other parameters, in the Cardiopulmonary Exercise Testing performed on the treadmill in individuals of both sexes, either active and sedentary.
