But I was thinking more in terms of perhaps cayenne, or maybe even a small amount of sugar after all - not for performance but with the aim of getting rid of the fat. Or maybe lifting weights before the aerobic session. I suspect competitive athletes would jump on it in a second. You will routinely see runners jogging around at low intensity immediately before a race to "warm-up". yes, to try and prevent injury To maximize performance during a race which might only take 15 -20 minutes they plan to consume all of their readily available glycogen, but if they can also burn more fat in addition than the other runners they will gain an edge. but not when oxygen, rather than fuel, is the limiting factor. I'd suppose it depends, as you indicate, on the duration. Of course the even light warm ups will burn some glycogen so there will be a trade off. At least in part the warm up also serves to prevent injury. oops, you did say that, But it's a lot of trouble to re-edit with this AOL software, sorry -- Ken Quote Link to comment Share on other sites More sharing options...
