Effects of Isocapnic Respiratory Muscle Endurance Training in Healthy Adults
Sponsor: University of British Columbia
Summary
Respiratory muscle training (RMT) strengthens breathing muscles and may improve exercise performance and reduce breathlessness. However, different training methods and devices create controversy in the field. Two main types of RMT exist: inspiratory muscle training (IMT) and respiratory endurance training, like voluntary isocapnic hyperpnea (VIH). While IMT is well-studied, the impact of VIH on breathlessness remains unclear. This study will use the Canadian-developed BreathWayBetter device to examine how 5 weeks of VIH affects breathing discomfort and muscle function. Findings may help personalize RMT for athletes and clinical patients, improving respiratory care and exercise tolerance.
