What about the products that only support inhale breathing?
Going back to the weight lifter analogy, why would you only train the muscles in your arms when you lift them up but not when you lower them. Training for “lift and lower” is training for a full range of motion for the muscles. So, why shouldn’t this be true for your breathing? Your expiratory (exhale) breathing is just as important as your inspiratory. Ask any musician or someone who has asthma.
In the 1990’s, a group in England joined together and introduced a product, POWERbreathe®, to focus only on IMT (inspiratory muscle training. One of the original founders also participated in research supporting the value of IMT only. A review published in March 2005 Curr Opin Pul Med, Review “Respiratory muscle training in chronic obstructive pulmonary disease: inspiratory, expiratory, or both?” gave this summary:
“Inspiratory and expiratory muscles can be specifically trained yielding improvements in both strength and endurance. The improvement in inspiratory muscle performance is associated with an improvement in the sensation of dyspnea, exercise tolerance, and quality of life. When the expiratory muscles are specifically trained, a significant increase in exercise performance has also been shown…”
Remember, POWERbreathe only does inhale training. Yes you exhale through it, but there is no resistance, no training benefit and no exercise effort of any kind for exhale.
The benefits of training with PowerLung have been proven time and time again. Each study showing that expiratory breathing is just as important as inspiratory breathing. One study would show an increase in exhale muscle power greater than 150%! The really great part about our proof is it’s not endorsed. Independent researchers approached PowerLung and requested to perform studies on our products.
