>Today's players have begun to incorporate strict food and fitness regimens to increase oxygen supply to the brain during tournaments

Is there really such a possible variance when it comes to getting oxygen to the brain? Why don't they just take hits of O2 then?

[cheald → pastor_elm]

Absolutely. The difference in VO2 max (essentially, efficiency of oxygen uptake) between trained and untrained individuals is stark and substantial.

Hits of pure O2 produce a euphoric high, which probably isn't what you want during intense mental competition.
