Powerbreathe Review: Effects on VO2max, Fitness, and Body O2
Powerbreathe (sometimes spelled as Power-Breathe) is a breathing device used to train inspiratory muscles by creating resistance that can be regulated. There are different versions of this device: including Powerbreathe Ironman, Plus, Medic, K series (or Kinetic), and many others. The device is similar to other respiratory trainers including Powerlung, UltraBreathe, Expand-A-Lung and some others. These devices are used mostly for sports performance, but there are medical applications as well (mostly for people with asthma and COPD).
In their articles and reviews, the creators of Powerbreathe claim that training of the inspiratory muscles is the most effective method to improve health and oxygen transport. Clinical trials have found some positive effects of this device on sports performance (Edwards et al, 2008; Edwards et al, 2004; Hart et al, 2001).
Surely, if this device can address the cause of low body-O2 content and poor endurance in modern general population and most athletes, then Powerbreathe can be very effective. But what is the cause of low O2 present in most people when they are at rest?
The training manuals and practical applications (e.g., in clinical trials) of Powerbreathe are based on one key recommendation that makes this device especially useful for athletes to increase VO2max and improve health. Exhalations, according to the creators of this breathing trainer, are slow and passive. Indeed, should exhalations be fast (assume that it was decided that training of expiratory muscles is also important), there would be virtually no benefits from this device.
But most people have incorrect ideas about breathing patterns for maximum body oxygenation. As a result, they try to breathe more air (sometimes or often) thinking that they can get more oxygen in the brain and body cells. However, hundreds of medical studies tell us that breathing more than the tiny medical norm (6 L/min at rest) reduces oxygen delivery to cells. How could this device improve oxygen levels in cells? Oxygen levels in body cells will be higher if the automatic breathing pattern after the sessions is slower and lighter (reduced minute ventilation and higher arterial CO2).
Could Powerbreathe lead to this effect? The training manuals and practical applications (e.g., in clinical trials) are based on one key recommendation that makes this device useful for athletes to increase VO2max and improve health. Exhalations, according to the creators of this trainer, are slow and passive. Indeed, should exhalations be fast (assume that it was decided that training of expiratory muscles is also important), there would be virtually no benefits from this device.
Powerbreathe vs. Expand-A-Lung, Ultrabreathe, PowerLung
You can get the maximum benefits from Powerbreathe if you follow some additional instructions related to lifestyle factors that naturally improve body-oxygen levels (prevention of supine sleep, nose breathing only, correct posture, and so forth). It is a mistake to compare Powerbreathe vs. Expand-A-Lung or Expand-A-Lung vs. Powerlung since it is how you use the trainer, rather than which trainer you use, that matters most for modern athletes.
The key factor for higher VO2max, endurance and body-O2 content is to condition the body to breathe less 24/7. If you try to exhale longer and even hold your breath after exhalations during breathing exercises with Powerbreathe (for advanced stages of training only), then you can get even more benefits from this device and achieve higher body oxygen level results and improved VO2max.
You can get even better results with the Training Mask (see the link below). The key advantage of Training Mask in comparison with Powerbreathe is that it is possible to use Training Mask during exercise. greatly amplifying various benefits related to increased body and brain O2 levels.
Warning. Breathing exercises can cause powerful cleansing reactions and can be dangerous for pregnant women, people with organ transplants, GI problems, and panic attacks, as well as those who take medication for diabetes, hypertension, hypothyroidism, and other conditions. Consult your health care provider and follow special guidelines, which can be found in the Module Restrictions, limits, and temporary contraindications.
