Exclusion criteria

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the variation in systolic blood pressure between the intervention group and the control group after performing breathing exercises associated with aerobic exercise on a cycle ergometer, verified through blood pressure measurement using the auscultatory method with sphygmomanometer and stethoscope, observing the difference between values obtained before and after the intervention in both groups | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the variation in diastolic blood pressure between the pre and post intervention moments in the intervention and control groups, verified through blood pressure measurement using the auscultatory method with sphygmomanometer and stethoscope, observing the difference between the values obtained before and after performing inspiratory muscle training associated with aerobic exercise on a cycle ergometer;Evaluate the variation in heart rate between the pre and post intervention moments in the intervention and control groups, verified through heart rate monitoring using a cardiac monitor during aerobic exercise on a cycle ergometer associated or not with inspiratory muscle training, observing the difference between the values recorded before and after the intervention;Evaluate the perceived exertion during aerobic exercise associated or not with inspiratory muscle training, verified through the Borg Rating of Perceived Exertion Scale, observing the values reported by participants during the intervention | — |
