POWERBreathe
POWERBreathe was developed from work by Professor Alison McConnell on inspiratory muscle fatigue: breathlessness, extra effort of breathing, and reduced exercise tolerance when those muscles tire.
The respiratory muscles take priority. When they are under load they can “steal” blood from the legs (the metaboreflex), which shows up as fatigue and a drop in performance.
POWERBreathe is a resistive device that loads the inspiratory muscles. It has been used in sport and in conditions such as asthma, vocal cord dysfunction / EILO, and COPD. It is simple to use and easy to use badly. A full breathing assessment first matters, so you do not load an unhelpful pattern.
A usable resting pattern comes before adding resistance. Assessment and programme setting (including K5 software where available) can be done at the clinics. There is also a path from foundation inspiratory muscle training into more sport-specific work.
