Dose-Response Effects of Inspiratory Muscle Strength Training on Blood Pressure and Vascular Function
Status: Recruiting
There is evidence that a short daily resisted breathing exercise, called inspiratory muscle strength training, can lower blood pressure and improve cardiovascular health. However, the most effective inspiratory muscle strength training protocol has not been established. This study seeks to test different training protocols. Participants will perform inspiratory muscle strength training daily, for 6 weeks. Each day's training will take less than 15 minutes to complete. Cardiovascular function will be measured before and after the 6-week training period.
