Introduction: Respiratory muscles strength is influenced by factors such as age, gender and anthropometry. In addition, physical activity may also influence it. Objective: To compare the values of maximal respiratory pressures in healthy adolescents with different levels of physical activity. Methods: Observational crosssectional study was carried out. A total of 182 healthy adolescents were assessed. Maximal respiratory pressures were measured with a digital manovacuometer and the levels of physical activity with the short version of an international physical activity questionnaire. Oneway Anova was applied to compare the variables among groups classified according to the level of physical activity. Results: There was significant difference in respiratory pressures between the groups classified as irregularly active A and B and active/very active. These two groups showed a mean MIP of 77.7±26.2 and 96.2±28.3cmH2O (p<0.001), respectively, and a mean O (p<0.001). Conclusions: The regular practice of physical MEP of 90.8±29.4 and 111.5±32.2cmH2O (p<0.001). Conclusions: The regular practice of physical exercise may significantly increase respiratory muscle strength in healthy adolescents.
