hyperventilation before a short TT(5 posts)

hyperventilation before a short TTishmael

There's a one and a half minute time trial coming up(manayunk wall) and I was thinking if I breath heavily just before taking off I could stay aerobic a bit longer. Lets say I breathed so hard that I was lightheaded? I also cant decide if I should ride in the drops or on the hoods. I'll be out of the saddle for sure, and I feel more powerful in the drops, but supposedly it's harder to breath. I havent done the tests to see but my habit is in the drops and habits seem good to keep to.

I think that you actually will lose air in your lungs and bloodstream if you do that, just stay on the traininer and taper up to the line start time.

Wow, never heard of anything like that.

I always do this at the beginning of timetrials, as well as before anticipated harder efforts in road races, before turns, hills, sprints, etc. I think it helps a bit.

It's really more of a matter of deep breathing than hyper-ventilation for me. Just remember to keep deep breathing as you begin riding, or you might lose the benefits.

Divers use hyperventilation as a means to stave off the respiratory reflex (the need to take in more air) when diving tankless (free diving). But those are very low energy states. I don't think there's any benefit for the type of effort you're looking at (and there's CERTAINLY no benefit to blacking out at the start).
1+ hr. warmup, + drops. No bag huffing. (nm)shirt
