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.

Detailed description

Hypertension is associated with an increased risk of cardiovascular morbidity and mortality, and its high prevalence remains a worldwide concern. Ambulatory blood pressure monitoring (ABPM) is recognized in the diagnosis and management of hypertension, and can control blood pressure better than clinic assessment. Different studies have examined the effects of aerobic training on ABP in patients with hypertension, but the effects of moderate-intensity interval training (MIIT) and moderate-intensity continuous training (MICT) on ABP and novel plasma protein biomarkers that could potentially serve to identify cardiovascular risk, have not yet been examined in patients with resistant hypertension.To fill this gap, our aims are to determine the effects of MIIT and MICT for 4 months on ABP (primary endpoint), and on proteomic biomarkers (secondary endpoints) in patients with resistant hypertension. A total of 72 participants will be randomly divided into three groups: the first group (n=24) will perform MIIT, the second group (n=24) will perform MICT, and the third control group (n=24) will maintain usual care for 4 months. All will receive usual care for 4 months, with the structured physical exercise as the only relevant change in the intervention groups.

Interventions

Type	Name	Description
OTHER	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.
OTHER	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).
