An article in Outside magazine reviewed research that found that by training your respiratory muscles you can help yourself to perform better with less oxygen - a definite advantage if you’re planning a trip to altitude.
The article refers to a study conducted in 2007 that revealed improvements in ‘exercise’ at an altitude of about 10,000 feet (3,048 metres) after 4 weeks of IMT. Results showed blood oxygen levels during exercise were higher and because the respiratory muscles were stronger the participants were able to handle the demands of breathing in thin air more easily which reduced their total oxygen usage. Participants also reported a reduction in breathing effort and discomfort.
Dr. Mitch Lomax has lead several research studies in this area and states in the article,
"Based on what we currently know, IMT is something that I would recommend prior to a trip to altitude.”
In her studies Dr. Lomax used POWERbreathe IMT for respiratory muscle training.
The respiratory muscles, primarily the diaphragm and intercostals weigh between 3 to 5 kilos (7 and 11 pounds) and consume energy and fatigue like any other muscle. And just like any other muscle they can be trained. By using POWERbreathe Inspiratory Muscle Training (IMT) devices you’ll be training in the most controlled, scientific manner, as POWERbreathe IMT has undergone scientific testing to establish the most beneficial protocol and all IMT devices are calibrated to provide reliable load testing time after time.
