• POWERbreathe K-Series is a handheld electronic inspiratory muscle training device and is the third generation of POWERbreathe products
• It is used to generate a resistance to inhalation in order to train the muscles used to breathe (diaphragm and intercostal muscles)
• Variable resistance training is generated by a variable disk valve which moves up to 4000 times per second
• Resistance is controlled in response to measurements of pressure, flow and volume calculated up to 500 times a second
• The system allows training to be continuously and precisely controlled in response to different measurements
• Provides feedback and measurements on training progress and inspiratory muscle performance

Length
Power Curve
The relationship between the length of a muscle and the contractile tension that it can exert
A muscle can usually exert its greatest contractile tension when it is at its resting length
At resting length has most active force

The POWERbreathe K-Series creates a variable load which matches the length tension relationship of the inspiratory muscles allowing more effective training than conventional constant load training.

During the first two breaths of a session, the maximum value of flow, and the pressure at which it is measured, is recorded.
Training resistance is extrapolated from the peak inspiratory flow using a typical inspiratory muscle force-velocity relationship.
Training intensity can be adjusted when in the automatic set-up mode in order to suit the user’s tolerance to exercise. Alternatively, training load can be entered manually.

Training ResultsThe POWERbreathe K-Series provides performance feedback following every training session
Load is a measure of the resistance to inhalation during your training session – the equivalent to the weight lifted by the inspiratory muscles.
Volume is the average volume of air inhaled per breath.
Power is the average power generated during your entire training session and is a combined measure of the force exerted by the inspiratory muscles and the speed of contraction.
Mechanical work (effort ) of breathing for the session. combines the force exerted by your inspiratory muscles and the volume of air inhaled
Note: Feature only available for K4, K5, and KH2 model

Single breath Test

The Strength Index test can be used to quickly assess inspiratory muscle strength at any time. The test calculates inspiratory muscle strength based upon the peak inspiratory flow during a single test breath. The test results also show the peak flow and inhaled volume from the test breath. These results can be used to monitor the effects of inspiratory muscle training. S-Index value is rated (from v.poor to excellent) based upon predicted normal values calculated using the profile information (age, height, weight and gender).
