No, actually caffeine inhibits your bodies capability to absorb oxygen.
Sure it raise your heart rate but studies have shown that caffeine can negatively impact how effectively your body uses it's oxygen.
I don't know roughly speaking you but I know when i work out, if I want to work out longer and harder... feeling close to you're getting the most air you can is slightly key.
Different answer for different people really... and difficult to determine for an individual. The first answer here is pretty nouns advice. For some population, though, short-term active men especially, caffeine intake won't inhibit oxygen satisfactory to countract the effects of spiked metabolism and short-term productivity (men have larger lung capacities). As for caffeine "vent fatty cells"... I've never heard such a piece.
