Aerobic Exercise and Resistant Hypertension

Condition(s) studied

Investigational drug(s) / intervention(s)

Moderate-intensity interval training (MIIT): MIIT group: participants will perform 3 sessions per week for 4 months. Each session will involve a ∼3 min warm-up (joint mobility exercises and walking at ∼2.2 METs), a ∼40-50 min main period (∼6-7 reps of 4 min at ∼4.2 METs, with 3 min of active recovery at ∼2.2 METs between each interval), and a ∼3-min cool-down (joint mobility exercises and walking at ∼2.2 METs). We will select the same aerobic dose of training (i.e., kcal/kg of body weight per week) to match total energy expenditure in both exercise groups.

Moderate-intensity continuous training (MICT): MICT group: participants will perform 3 sessions per week for 4 months. Each session will involve a ∼3 min warm-up (joint mobility exercises and walking at ∼2.2 METs), a ∼40-50 min main period at ∼3.2 METs, and a ∼3-min cool-down (joint mobility exercises and walking at ∼2.2 METs).

Study summary

This study will examine the effects of 4 months of aerobic interval training versus continuous aerobic training on ambulatory blood pressure (ABP) and novel plasma protein biomarkers in patients with resistant hypertension. A randomized controlled trial will be performed including two exercise groups and a control group: a) moderate-intensity interval training (MIIT); b) moderate-intensity continuous training (MICT); c) usual care. MIIT could represent a superior training modality that exceeds the benefits of MICT in patients with resistant hypertension.

Eligibility

Primary outcome measure(s)
