Cardiorespiratory Fitness of Healthy Individuals in the Midwest Region of Brazil
Abstract
Introduction:
Cardiorespiratory fitness (CRF) is an essential component of health-related physical fitness, and its reduction is associated with a higher risk of cardiovascular disease and increased mortality. The peak oxygen consumption (VO2 peak) obtained via the Cardiopulmonary Exercise Test (CPET) is compared to predicted normal reference values, providing a more accurate and individualized CRF classification. However, currently predicted values available arose from data from different countries or regions in Brazil that might present different demographic and biopsychosocial characteristics than Brazil’s Midwest region.
Objective:
To establish VO2 peak reference values for Brazil’s Midwest region.
Method:
A retrospective observational study with a direct analysis of the VO2 peak via CPET in healthy individuals from Brasília – Brazil’s Midwest region. Data were analyzed in an exploratory and inferential fashion.
Results:
7,843 exams were initially assessed according to the eligibility criteria of the study. According to inclusion and exclusion criteria, 2,790 exams from including only healthy individuals were considered providing information regarding the peak oxygen consumption (VO2 peak) over the different age groups (20-29, 30-39, 40-49, 50-59, 60-69 and 70-80 years) and gender, establishing new reference values for Brazil’s Midwest region. Higher values were observed in male and younger age groups.
Conclusion:
The present study provided new VO2 peak reference values for Brazil’s Midwest region, improving CRF accuracy and correctness for this Brazilian region.
