Overview
What is this study about?
This is a research study investigating the effects of inspiratory muscle training (IMT) on cardiovascular function, muscular fitness, and mood in postmenopausal women. IMT works by strengthening the respiratory muscles through resistive airflow breathing using a handheld device.
Who can participate?
Postmenopausal women (50-75 years of age).
Description
What happens during study participation?
- Attend in-person visits (4 total + screening and device pickup visits) to the IU School of Public Health (1025 E. 7th Street, Bloomington, IN 47405).
- Study visits will involve baseline assessments of body measurements/height/weight/blood pressure, completing questionnaires, performing pulmonary function tests, a standard blood draw, a 30-second sit-to-stand test, a series of walking tests, cerebral vascular measures, and familiarization with inspiratory muscle training (IMT).
- Complete 8 weeks of home-based inspiratory muscle training (4 times per week) using a flow-resistive inspiratory muscle trainer device from the third-party company called PrO2Fit. The training device is hand-held and will be connected to a tablet or smartphone via a wireless Bluetooth connection and simulates the sensations of lifting weights at high repetition. During IMT, you will be training your respiratory muscles like you would in the gym lifting weights. You will be inhaling through the device as hard and as long as you can until you quit, and you will try to complete a certain number of respirations and sets with shortened rest time.
- Study participation lasts 11 weeks
Incentive/compensation
- Participants will receive up to $200 in VISA gift cards for completing all of the study requirements.
- Parking costs will also be covered.
