The POWERbreathe K3 is a hand held, electronic inspiratory muscle training device that offers you an advanced level of breathing training, without any software to deal with.
In addition to the features of the K2, the K3 also includes additional training modes for warming-up your breathing muscles and a cool-down or ‘recovery’ after exercise.
The K3 stores data of your previous 36 training sessions.
The POWERbreathe K-Series is the world’s first range of intelligent digital breathing training devices.
The K-Series uses a patented and researched based ‘intelligent tapering system’ that matches the strength profile of your breathing muscles, providing you with the most effective way of training your breathing muscles, compared to conventional methods.
The K-Series devices feature an electronically controlled ‘tapered flow resistance’ that uses a computer controlled rotary valve to create the resistance to your in-breath. As a result of this, resistance is not fixed at the same level throughout your breath (unlike a pressure threshold device), because the device automatically reduces the resistance as you progress through your breath, matching the load to your declining muscle strength.
The tapered flow enables you to perform a longer inspiration and use a wider range of breathing muscles so you achieve higher flow and higher tidal volumes for better results. It achieves this by automatically adapting to increases in your inspiratory muscle strength at the beginning of each training session. What this means is that the training load is highest at the start of your inhalation and then gradually decreases as your lungs fill with air.
During the first two breaths of each training session there is no resistance and you should inhale as quickly and deeply as possible. It’s during these breaths that the K-Series device measures your maximum breathing capability. Training load is then gradually introduced during breaths three and four until full loading is achieved for breath five and onwards. During these breaths you will find it increasingly harder to inhale.
Training measurement results are displayed on the device’s LCD screen, allowing you to monitor training progress and optimise your training technique.
This study concluded that the K-Series device “provides automatically processed and valid estimates of physical units of energy during loaded breathing tasks…”

Declaration of Conformity
Vanessa Potter – May 4, 2022
Posted on behalf of J Williamsen who submitted his review via our blog, ‘IMST to Lower Blood Pressure‘.
I began using the K3 in late October, 2021, after a bout of COVID-19 (and corresponding loss of stamina) and after reading the research paper on IMST for blood pressure lowering (I have had hypertension for almost 30 years, taking 3 antihypertensive medications).
I have never followed the training regimen described in the research paper. Rather, I have just used the K3 on its automatic (not custom) setting, thirty inspirations (per the automatic setting) in one sitting, sometimes stopping for one/two breaks in the 30 inspirations (to swallow saliva).
I have kept track of my session results, which gradually improved over time, and are now at asymptotic level for me (I am 83 years old; my “load” score is now ~50 each day). My systolic BP has dropped significantly and, over time, I have also reduced my medication by half. My regimen is one set of 30 inspirations (the default K3 protocol), one time per day, seven days a week.
I have made the K3 30 IMST/session part of my daily care regimen and am grateful to PowerBreathe for their devices and the research studies in support of IMST training.

What is auto-optimising technology?
The K-Series automatically estimates your training load at the beginning of every training session. Using this method, the device will adjust the training load every time you start a new session and as the strength of your inspiratory muscles increases. Automatic setup of this load takes place during the first two breaths of each training session.
Have measurements been independently validated?
Can more than one person use the same device?
For hygiene reasons, we recommend that users do not share the same valve head and mouthpiece. However, additional additional valve heads with mouthpiece are available for all K-Series models.
Does my K-Series model ever need re-calibrating for maintaining accuracy?
It really varies based on the user e.g. trainer, private individual, as well as personal needs. We offer a calibration service to meet the needs of the respective groups. Individuals may wish to have this service for peace of mind in the knowledge that their device is functioning correctly. However, due to calibration being a chargeable service, you may choose not to.
