ABSTRACT Introduction: Urban green spaces can offer opportunities for regular physical activity, providing benefits in the lives of members of the population, such as physical, social and affective health. The aim of this article consists of analyzing the influence of urban green spaces on physical activity, focusing on urban environmental quality and the health of those who engage in physical activities in open areas. The study has a multidisciplinary approach from the perspective of environmental health. Method: The study design was based on qualitative research, using a bibliographic and document search as well as field surveys, whose technique involved direct observation (DO). The sample selection was based on Miot (2011), consisting of a total of 36 individuals aged between 18 and 40 years, who perform physical activities regularly, at least three times a week, for at least 50 minutes. Questionnaires were also applied using the IPAQ (assessment of physical activity) and Borg Scale parameters. Results: The study showed that the research participants became more active, possibly being stimulated and motivated by their surroundings with widespread vegetation cover, the good infrastructure of the venue and the guidance provided during the research. Conclusion: The research project showed that the greater the frequency and intensity of physical activity in open areas, the better the body's physiological adaptability.
