I was wondering whether anyone here has tried, or heard anything about the efficacy of, Airofit. Essentially, as I understand it, it’s a gizmo which pairs with an app and which enables a person to do a range of exercises which are aimed at improving the strength of the diaphragm (and thus increase lung capacity). To my extremely unscientific mind the theory seems to make sense - the diaphragm is a muscle, so its function must be capable of improvement with the correct training, and it’s also a muscle which (though we all use it) isn’t generally “trained” in a conventional sense, so promoting a greater awareness of, and control over, it could have a benefit in a sport which relies in large part on efficient oxygen take-up.
The testimonials they cite seem to be impressive, with users reporting relatively significant lung capacity improvements (presumably due to being able to breathe ‘deeper’ after training), but what I was wondering is whether there is any science out there that backs it up. I do know that the ‘altitude mask’ type things (which, if I’ve understood correctly, aim to artificially limit the amount of air available to simulate being at altitude) are considered to be something of a gimmick, but I don’t know what to make of this. Any thoughts?
