INTRODUCTION: The regular practice of physical activity is associated with improved health status, increased functional capacity, increased muscle strength and reduced mortality from heart disease. Although the benefits of regular exercise are well established in the literature, adaptations in inspiratory muscle strength and endurance are controversial. OBJECTIVE: To test the hypothesis that there is no difference in the strength and resistance of the inspiratory muscles between active and sedentary individuals. METHODS: Cross-sectional observational study. It was evaluated individuals between 18 and 30 years old, both sexes and healthy. The volunteers were divided into active and sedentary according to the classification of the American College of Sports Medicine (ACMS). Individuals had maximal inspiratory muscle strength (IMS) determined through the POWERbreathe® K5 inspiratory muscle trainer, which injects this variable as Sindex. The inspiratory muscle strength was evaluated through an incremental test. For the comparison of the means the student's t-test was applied for symmetrical distribution, p <0.05. The study was approved by the research ethics committee with CAAE: 37781014.4.0000.5544. RESULTS: A total of 92 individuals were evaluated. Of these, 55 (60%) were classified as active and 57 (62%) were male. When comparing Sindex between active and sedentary (128 ± 26/119 ± 24 cmH2O, p = 0.85) and exhaustion in the incremental test (63.2 ± 16.1%. p = 0.095), respectively. CONCLUSION: Active individuals do not present stronger and stronger inspiratory muscles when compared to sedentary ones.Downloads
