Abstract

 Introduction: Residents of large cities are highly exposed to pollutant particles that negatively influence bodily systems, primarily the cardiorespiratory. The maximum oxygen consumption (VO2max) corresponds to the individual's maximum aerobic capacity, measured by pulmonary breathing or exercise testing, demonstrating the systemic physiological adjustment. However, there are several factors that can influence VO2max, gender being one of them. Methodology: 200 individuals residing in Greater São Paulo, Group 1 and residents of Baixada Santista, Group 2 were evaluated. All patients underwent cardiorespiratory testing to determine the level of physical fitness (VO2max), divided into 2 groups by gender: Group 1= Age: 30±0.3 years (50 women and 50 men). Cardiopulmonary testing was performed, a test analyzing the peak of oxygen consumption during maximal exercise. Data were presented as mean ± standard deviation. The STATISTIC 9.0 program was used for the analyzes and the one-way variance test applied to compare respiratory data between groups. Values ​​of p<0.05 considered statistically significant. Results: The groups were similar in peak oxygen consumption: Group 1= 17.5±0.04 ml/kg/min and Group 2, 18.3±0.08 ml/kg/min. We did not observe differences in VO2max between males compared to females. (F/ VO2 = 17.59 ml/kg/min and M/ 21.35 ml/kg/min). Conclusion: We can conclude that there were no differences in VO2max between males when compared to females.
