Why are VO2 max sets so hard?(12 posts)

Why are VO2 max sets so hard?PODIUMBOUNDdotCA

Does anyone have an explanation for why a VO2 max set is so hard on your body? Most people after they are done a VO2 max workout just want to sleep.

maybe i'm not understanding your question but..._rt_

i'm going to answer it anyway! ;-)

i'm not sure exactly what a VO2 max "set" is but having done a VO2 max test the whole point of the test is to determine what the max output is. as such you are to go until you literally pass out. (i stopped just before blacking out for fear of falling down and knocking out my teeth!) during my VO2 max test i got & sustained my HR over 200 bpm. when i got finished i felt like i'd been hit by a truck.

i'm assuming that a VO2 max set would be a set in which you push yourself to the point of max output. as such you are depleating yourself of O2 which, in turn will make you feel sleepy when you are done. your body will need to rest to replete O2....not to mention there is probably a good amount of adrenalin being put out during the set. once that wears off you will feel exhausted.

just my uninformed $0.02.
Thanks! Exactly what I was looking for! (nm)PODIUMBOUNDdotCA

George Sheehan, the running philosopher (and cardiologist, now deceased) wrote up an article about his VO2max test many years ago. I'll paraphrase what he said:

As the test ended, I tried to come up with some equivalent physical feat to compare it with.
"When can I see the baby?" I asked, as I heaved my chest for breath, slumped in the corner.

Maybe that will answer your question.
like a time trial?trekkie1

I've not done a max test. Is the effort essentially the same as an all out time trial?

like till you pass out.

hopefully you've never passed out during a TT!

and you've got this apparatus on your head, a big tube taped onto and sticking out of your mouth (attached to the machine) and a clothespin on your nose to make sure you only breathe through your mouth.

the goal is to go until you literally can not continue. not till you think you can't continue, but until you fall down.

sound fun? ;-)

They do one of these tests in the movie American Flyers. Fairly accurate. Definitely not something I'd look forward to.

My VO2 max test was just like racing up my fav canyon except that it took half the usual time. After a few mins I was recovered and had to walk back to work. I used my own bike and did the test with my PowerCranks on... that was fun.

I didn't mean it like that... The reason the test wasn't all that bad is because I do not have great leg strength and that is my limiting factor. I have a competitive running background and started cycling (racing) a year and a half ago. My cycling musculature is not well developed. There comes a point where you just can't pedal anymore and you start mashing and your HR and RER actually starts going down from their peak values. At that point the test is over. People who have been cycling for a long time probably don't have this problem.
