Max effort sessions like this are the only time I’d use mouth breathing. Sprints with very little rest periods. I don’t play a sport or do long distance runs but there’s a way everyone can bring into there training & lifestyle
If you aren’t a top level athlete with a one off event in the next few weeks, I’d 100% recommend committing and training nasal only across all cardiovascular work, including high intensity, just adjust the pace. If you’re just training for enjoyment & health like the majority there’s no reason not to
Pitch based sports incorporate it mid week & huge benefits warmups pre training & pre games. Game time it’s a one off event do whatever
Mouth breathing you’re doing yourself quite a disadvantage and will by default create dysfunctional breathing to some degree. Not only in your capacity, remember Co2 is produced by working muscles not just your breathing rate, if you have a very high tolerance you reduce the panting effect to off load it, higher Co2 levels result in faster release of oxygen to the body, you also absorb more oxygen, combined blood flow benefits from Co2 + nitric oxide, which you by pass by mouth breathing. If you have a very high tolerance you automatically have very efficient breathing mechanics - breathing effects you mechanically, chemically, psychologically.
I’ve been posting this for years, take it with a pinch of salt, it doesn’t mean you physically shouldn’t open your mouth during effort, but strip it back, why do you have a nose
It’s more the effect outside of training from building a very high tolerance - lower breathing rate, more oxygen absorption & blood flow (body & brain), calmer, better sleep
Session was 15cal sprints you go I go 4 rounds. So about 20-25s rest between. Short max effort interval. Lungs & fatigue hit quick
