IF I INHALE PURE OXYGEN RIGHT BEFORE A RACE...WILL I RUN FASTER?

Marginally, maybe, if you don't pass out.

A typical HALO exercise will require a pre-breathing period (30-45 minutes) prior to jump where the jumper breathes 100% oxygen in order to flush nitrogen from their blood stream. Also, a HALO jumper will employ an oxygen bottle during the jump. Danger comes from medical circumstances affecting the jumper. For example, cigarette smoking, alcohol and drug use (including antihistamines, tranquilizers, sedatives, and analgesics), anaemia, carbon monoxide, fatigue and anxiety can all lead to a jumper being more susceptible to hypoxia. In addition, problems with the oxygen bottle and during the changeover from the pre-breather to the oxygen bottle can result in the return of nitrogen to the parachuter's bloodstream and, therefore, an increased likelihood of being affected by hypoxia. Just one breath of regular air will bring the jumper's blood nitrogen levels close to normal[citation needed]. A jumper suffering from hypoxia may lose consciousness and therefore be unable to open his parachute.

just sayin david blaine did it to hold his breath under water for 17 min.

ONLY IF YOU TYPE IN ALL CAPS!

Nope, the amount of oxygen you breathe in isn't the limiting factor in your running. In fact, you don't even use all the oxygen you breathe in, you breather some of it right back out.

Many people don't realize that the reason their lungs are burning isn't oxygen deprivation but because carbon dioxide is building up.

The air you breathe in is 21% O2, and you breath out 16-17% O2.

However Bannister did studies with different amounts of oxygen and the higher amounts improved performance when they were breathing the gas with higher O2 concentration. 2/3 O2 was the best, better the 100% O2.

Just sniffing extra O2 at the start wouldn't do much for a distance race, although there are stories in Lore of Running about 400-800m runners inhaling Oxygen then running fast times with reduced fatigue, and a feeling of euphoria.

No, it won't. And breathing oxygen after running does not help you "catch your breath" either. Here is why...

The vast majority of oxygen is transported to your muscles bound to hemoglobin. Your

arterial hemoglobin is already maximally saturated with oxygen (at sea level) and stays that way even during maximal exertion.

The only time supplemental oxygen might be beneficial is if you were racing at altitude and you could bring the oxygen tank with you.

use the search function.

Inhale a balloon full of helium right before the run start. You'll feel lighter, physically and mentally.

If you breathe it DURING exercise, yes it will aid in performance.

Do a PubMed search on research by folks like Wilber, Morris, and Callan (amongst others) on supplemental oxygen. These studies dealt with athletes at altitude who trained on mixtures of gases to simulate sea level or what would effectively be below sea level gas mixture.

Jerome Dempsey up at Wisconsin. I think has done some work in this area. Turns out highly trained athletes with very high cardiac outputs have such fast pulmonary transits times, during very intense exercise, that blood/hemoglobin does not get fully saturated.

Usually it's about 98% at rest in arterial blood but values as low as 85% were seen in some of his studies.

Shouldn't make a difference at rest because the amount of oxygen that can dissolve in blood is very, very small unlike CO2, therefore when hemoglobin is fully saturated there is essentially no significant additional storage of oxygen in the blood, plasma, rbc etc.

This is what I was going to say. Check out Lore of Running.

is everyone on this thread retarded. if u inhale pure o2 before your race it will benefit you for appoximately the 3 seconds it takes before you take in your next breath..... i can't believe people are actually considering this plausible..... MYTH BUSTED!

Try training retard!

Why are you calling people names is it because your only achievement in life is that you can run? Did your parents hurt you as a little kid by insulting you and now you are stuck in that mindset because of the deep seated trauma? Its not that big a deal really #MommyDidntLoveYou

No

I used to purposely hyperventilate at the start line of 5k and 10k races. All it did was make me dizzy

That's why high VO2 max is king. If you're breathing the oxygen right back out it means you have a low number.

Roger Bannister tested oxygen breathing on himself. It works.

Bannister participated in those studies in his run up to his sub 4 mile. O2 allowed him to train longer and with more intensity than he could have without it, which one assumes resulted in a greater adaptation response.

Exactly what you don't want if you are going to be using skeletal muscle. You need nitrogen around to facilitate muscle/blood gas exchange.

No you won't go faster, because the beginning of the race is anaerobic, with oxygen uptake rising gradually.
