Breathing physiology indicates that when your lungs are empty the breathing muscles are at their strongest. However, as they fill up with air they start to lose strength and therefore at high loads they can’t maintain a full contraction throughout an entire breath.
The POWERbreathe K-Series uses Electronic Variable Threshold Resistance Training to overcome this. This type of training offers a tapered loading resistance to match the contraction curve of your own breathing muscles throughout your entire breath. This enables you to complete a full breath and muscular contraction at an optimal resistance.
The K-Series will automatically adapt to increases in your inspiratory muscle strength at the beginning of each training session.
