2. 2nd and 3rd days of the experimental protocol: all volunteers will be randomly assigned to two exercise sessions (ES): Sham IME (no load) and moderate intensity IME (40% of MIP). Initially, the volunteers will perform a 10-minute supine rest for heartbeat collection and subsequent calculation of heart rate variability (HRV), blood pressure and forearm blood flow measurements and evaluation of the baroreflex system. In sequence the ES will be conducted with continuous monitoring of blood pressure, heart rate and subjective perception of effort through the Borg Scale. Immediately and until one hour after the ES, it will be measured forearm blood flow, blood pressure, heart rate and evaluated the baroreflex system and HRV in order to investigate the acute effect of ES. The volunteers will be monitored using an equipment capable of evaluating the outpatient measurement of blood pressure and electrocardiogram for 24 hours in order to investigate the chronic effect of ES.
