Respiratory Muscle Function in Heart Failure
“Respiratory Muscle Function in Heart Failure”
This study is being done because investigators are trying to determine how respiratory muscle and lung function influence the exercise responses in heart failure and healthy participants. Further, the heart failure patients will participate in an intervention to improve their respiratory muscle function to determine if this improves exercise capacity.
Device - PowerBreathe (Breathing muscle training)
The breathing muscle breathing training will consist of using the PowerBreathe training for 8 weeks. The PowerBreathe is an inspiratory pressure threshold trainer.The valve blocks the airflow until the threshold pressure is achieved by breathing in forcefully into the device.
