Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Good reproducibility of blood pressure reduction after exercise, evaluated by blood pressure measurements, before and after interventions. A good reproducibility will be defined by the following parameters: Absence of systematic error, evaluated by paired t test between test and retest, adopting a significance level of p < 0,05; Good reliability determined by an intraclass correlation coefficient equal or greater than 0,75; Good agreement represented by a low coefficient of variation (<10%). | — |
Secondary
| Measure | Time frame |
|---|---|
| Good reproducibility of cardiac output, heart rate, autonomic cardiac modulation and vascular function, evaluated respectively by CO2 rebreathing, electrocardiogram, spectral analysis of heart rate variability and venous occlusion plethysmography, before and after interventions. A good reproducibility will be defined by the following parameters: Absence of systematic error, evaluated by paired t test between test and retest, adopting a significance level of p < 0,05; Good reliability determined by an intraclass correlation coefficient equal or greater than 0,75; Good agreement represented by a low coefficient of variation (<10%). | — |
