- Brief Summary
This study finds the effectiveness of inspiratory muscle threshold loading training among adults with hypertension. A sample of hypertensive subjects was divided into two groups - inspiratory muscle training (IMT) - group (inspiratory muscle training was prescribed) and sham-group (no load was prescribed during IMT). Both groups had training sessions comprising seven cycles of two minutes bouts of breathing counter to an inspiratory load, each bout parted by one minute of unloaded recovery. Treatment session was performed for three times per week for a total of six weeks. Measurement of each of the variables (blood pressure, resting heart rate (RHR), heart rate variability (HRV)) was taken at baseline and after the six-week intervention.
- Detailed Description
The present study aimed to examine the outcome of interval inspiratory muscle training at 70% load on blood pressure, resting heart rate and autonomic dysfunction in the hypertensive adults.
Participants were divided into two groups: IMT and sham. In IMT group, the threshold loading inspiratory muscle trainer from POWERbreathe was used with 70% IMT threshold. In Sham group, IMT was unloaded.
