POWERbreathe – Improves Exercise Performance

• Improved inspiratory muscle strength by 31.2%
• Improved inspiratory muscle endurance by 27.8%
• Reduced whole body effort during exercise
• Accelerated recovery during repeated sprints by up to 7%

• Improved performance within 4-weeks (following tried & tested training regimen)

POWERbreathe Inspiratory Muscle Training & Fitness

When we climb hills or stairs, we are suddenly exposed to high intensity exercise that, for most of us, is above our lactate threshold. At these intensities our breathing moves out of its 'comfort zone' and increases steeply. This sudden increase in inspiratory muscle work is perceived as breathlessness.

Breathlessness is a common feature of normal exercise and although aerobic activity does provide training benefits to the inspiratory muscles (the muscles we use to breathe in), it’s not sufficient to elicit their full potential. The breathing muscles never really get trained enough to cope with ‘heavy breathing’ and for this reason it will always present an uncomfortable challenge.

If the inspiratory muscle are weakened or fatigued, breathing feels harder. A useful analogy is to think about how much heavier a barbell feels on the 12th repetition than it did on the first.

Research also suggests that during heavy exercise, blood flow (and hence oxygen delivery) to the exercising muscles is inversely related to respiratory work. What this tells us is that the inspiratory muscles are capable of stealing blood from other working muscles, and in so doing, can impair their performance.

The good news is that when you subject the inspiratory muscles to an appropriate training stimulus i.e. POWERbreathe, they will adapt, increasing their strength, power and endurance.

The most striking outcome of research on exercise performance is the universal reduction in whole body effort sensation that results from just 4-weeks of POWERbreathe training. People simply don’t feel that they are exercising as hard, so there’s the potential to push yourself a bit harder, increasing your training intensity and ultimately your performance.

Train smarter, not harder, to perform better.
