....in layman's terms, the air is not as dense at higher altitude.
Not exactly............The important effect of this decrease in pressure is this: in a given volume of air, there are fewer molecules present. This is really just another way of saying that the pressure is lower (this is called Boyle's law). The percentage of those molecules that are oxygen is exactly the same: 21%. The problem is that there are fewer molecules of everything present, including oxygen.
So although the percentage of oxygen in the atmosphere is the same, the thinner air means there is less oxygen to breathe.
I don't know much about the masks, but I do know that in order to wear one, you'd be seen wearing one and that would seem a little bit like blasting Bro Country out of your car windows. I think I'll skip the mask
I agree. I told the trainer I would pass out if I had to run and breathe through my nose. LOL.
I think you'll get a whole lot more benefit out of running hill repeats till you're ready to puke instead of trying to breathe through your nose.
Google "Marshawn Lynch training mask." He wears it during pre game workouts. It's supposed to reduce oxygen simulating higher altitudes. There's a nice SI article on it. Not sure if it increases oxygen in the blood stream though which is what acclimization does.
Best thing to do to prepare for high altitudes is to pre hydrate. And rest if you get any symptoms and re hydrate.
