Expand-A-Lung Review: Effects on VO2max, Fitness and Body O2
The Expand-A-Lung breathing resistance exerciser is a breathing device used to train the respiratory muscles by creating resistance that can be regulated. This is the smallest and most durable breathing trainer. There are several related devices including Powerlung, Powerbreathe, UltraBreathe and a few others with reviews (see the links to their reviews below). All of them are used mostly for fitness and sports performance, with some studies and popularity among COPD and cystic fibrosis patients.
All these devices, Expand-A-Lung included, improve the strength of the inspiratory (and sometimes expiratory) muscles. This is indeed the main (but superficial) result of such breathing exercisers. As with other devices, the most important result - often overlooked - is the change in body-O2 content and automatic breathing patterns after weeks of training with the Expand-A-Lung.
First, let us review the key cause of poor endurance and low body-and-brain O2 content in the contemporary general population.
Expand-A-Lung can reverse this situation. For example, in one Swiss study, it was found that athletes, after breathing training, reduced their minute ventilation for a given exercise intensity. There is only one explanation for this effect: improved body oxygen level due to a slower and lighter breathing pattern at rest. This effect is based on the fact that exhalations with the Expand-A-Lung breathing resistance exerciser are passive or slow. This allows gradual accumulation of CO2. Hence, if we consider CO2 changes only, all these breathing trainers and devices (Powerlung, Powerbreathe, UltraBreathe, Expand-A-Lung, Frolov breathing device, Samozdrav, Breathslim, DIY Breathing Device, and many others) can be beneficial for higher body oxygen (see the test below), better health, and sport performance. Training Mask though offers one essential advantage: it can be used during exercise, for up to 1-2 hours per day (see the link to its review below).
Expand-A-Lung vs. Powerbreathe, PowerLung, UltraBreathe: Instructions
While many athletes may want to compare Expand-A-Lung vs. Powerbreathe or Expand-A-Lung vs. Powerlung, it is more important how you use the breath trainer rather than which one you use, while the safest and most effective device is Training Mask. You can get even more benefits from Expand-A-Lung or the other devices, if you follow additional ideas related to your lifestyle factors (see the Learning Section) to increase body-oxygen levels 24/7. These are our certain Expand-A-Lung instructions.
Practical Expand-A-Lung instructions
The key to endurance, higher VO2max, focus and higher body-O2 content is to train your body to breathe less 24/7. Therefore, if you try to exhale even longer (with air hunger at the end) and hold your breath after exhalations during breathing exercises (for advanced students only), then you can get even more benefit from the Expand-A-Lung. If you attach a light plastic 0.25-1 L bottle (depending on your fitness) to the trainer, you can recycle your CO2 and can get more benefits from the Expand-A-Lung.
Do you know that there are many clinical studies that measured effects of the Expand-A-Lung? The collection of these studies with their results are provided right below on this page as your bonus content. You can unlock it easily.
