Design outcomes
Primary
| Measure | Time frame |
|---|---|
| post-exercise hypotension - evaluated by the measurement of clinic (auscultatory) and ambulatorial (oscillometric) blood pressure before and after rest and resistance exercise while receiving placebo and captopril. | — |
Secondary
| Measure | Time frame |
|---|---|
| hemodynamics - evaluated by the measurement of cardiac output (CO2 rebreathing)and heart hate (ECG) performed before and after rest and resistance exercise while receiving placebo and captopril. Systemic vascular resistance and stroke volume will be calculated.;Autonomic modulation - evaluated by the measurement of heart rate and blood pressure variabilities (spectral analysis) performed before and after rest and resistance exercise while receiving placebo and captopril;Vascular function - evaluated by the measurement of baseline blood flow and its response to the reactive hyperemia maneuver (venous occlusion pletismography) performed before and after rest and resistance exercise while receiving placebo and captopril. | — |
