Hypertension, Metabolism Disorder
Conditions
Brief summary
Despite exercise training decrease blood pressure in 'average' terms, there is a wide interindividual variability after exercise training, being yet unknown what mode of exercise (e.g. endurance, strength, concurrent, or high intensity interval training) produce more/less non-responder (NR) prevalence (i.e., percentage of subjects who experienced a non-change/worsened response after training in some outcome).
Detailed description
Despite exercise training decrease blood pressure in 'average' terms, there is a wide interindividual variability after exercise training, being yet unknown what mode of exercise (e.g. endurance, strength, concurrent, or high intensity interval training) produce more/less non-responder (NR) prevalence (i.e., percentage of subjects who experienced a non-change/worsened response after training in some outcome).
Interventions
High Intensity Interval Training pre-hypertensive group; Exercise will be performed at three sessions per week. All sessions will be supervised by an exercise physiologist during 16 weeks.
Moderade Intensity Interval Training pre-hypertensive group; Exercise will be performed at three sessions per week. All sessions will be supervised by an exercise physiologist during 16 weeks.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in systolic blood pressure and diastolic blood pressure | Baseline and 16 weeks immediately after the interventions ends | After this, we calculated the delta changes in both variables and classified to all subjects in responders (R) and non-responders (NR) to decrease systolic or diastolic blood pressure. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in body mass index | Baseline and 16 weeks immediately after the interventions ends | BMI will be calculated as the body weight in kilograms divided by the square of the height in meters. |
| Change from Baseline in waist circumference | Baseline and 16 weeks immediately after the interventions ends | — |
| Change from Baseline in fat mass | Baseline and 16 weeks immediately after the interventions ends | — |
| Change from Baseline in body mass | Baseline and 16 weeks immediately after the interventions ends | — |
| Change from Baseline in fasting glucose | Baseline and 16 weeks immediately after the interventions ends | — |
| Change from Baseline in lipids | Baseline and 16 weeks immediately after the interventions ends | Lipid profile (low-density cholesterol, total cholesterol, high-density cholesterol and triglycerides) |
| Change from Baseline in one maximum repetition strength test of leg-extension exercise | Baseline and 16 weeks immediately after the interventions ends | — |
| Change from Baseline in heart rate at rest | Baseline and 16 weeks immediately after the interventions ends | Baseline and 16 weeks immediately after the interventions ends |
