Summary

This clinical trial aims to assess the efficacy of inspiratory muscle strength training (IMST) guided by a smartphone app vs. IMST delivered in a clinical research setting for lowering systolic blood pressure in adults 18 years and older with elevated blood pressure. Participants will perform IMST for 5 minutes a day, 6 days a week, for 6 weeks.

Interventions

DEVICE

App-Based Inspiratory Muscle Strength Training

Participants will perform inspiratory muscle strength training guided by a smartphone application. Participants will perform 30 breaths a day at 75% of maximal inspiratory pressure, 6 days a week, for 6 weeks. All training sessions will be guided by the smartphone application.

DEVICE

Clinic-Based Inspiratory Muscle Strength Training

Participants will perform inspiratory muscle strength training guided by researchers. Participants will perform 30 breaths a day at 75% of maximal inspiratory pressure, 6 days a week, for 6 weeks. One training session each week will be performed in the research clinic.
