What is IMT?
IMT stands for Inspiratory Muscle Training and it refers to exercises that strengthen the muscles involved with breathing air into your lungs.
How does IMT training help fitness?
Research shows a correlation between increasing your inspiratory muscle strength and inspiratory capacity with an increase in aerboic fitness levels.
How often do I have to train to see results?
Studies show that 30 minutes three times a week will provide you with measurable results within 6 weeks.
How long has IMT been around?
IMT was first described almost 40 years ago. The interval training system with computer feedback used in the Pr02 was first described by Ken Chatham over 20 years ago. The PrO2 is unique in it's ability to maximally train inspiratory muscles to increase respiratory fitness.
Is there research to backup your claims?
Yes, our unique approach is supported by multiple published studies written over almost 20 years in the medical and sports press. See our research section for more details.
What should I expect during training?
It typically takes 1 week (3 trainings) to learn the best techniques. Weeks 2 and 3 are termed neural adaptation - that is you acquire the muscle skills to coordinate all the muscles for optimum breathing. From 4 weeks on you get structural/morphological change in your muscle itself with plasticity so that fibers actually change roles. For example you may get a higher proportion of endurance fibers while your power fibers get bigger.
Why are my scores getting better during a session? Shouldn't they be going down?
When you first start training, it's not uncommon that you will get your best inspire for a session on the third, fourth or even fifth set. This is because you are learning how to take a maximum breath. After the first few weeks of training, you should ideally have your strongest breath for your baseline.
How does PrO2 training increase aerobic capacity?
The PrO2 is training your inspiratory MUSCLES. The stronger those muscles are the easier it is to move air in and out of the lungs. Also, when your inspiratory muscles fatigue, it appears to be a trigger for your brain to stop activity.
