Puking during training

"Pukie" is a something celebrated in CrossFit culture. The ideal that one puked is proof one pushed themselves very hard. I think it has a lot less to do with actual metabolic effort put forth and more to do with rapid up-down movement with the head. This up-down movement will affect the vestibular systen, which will stimulate the chemoreceptor trigger zone, which results in motion sickness.

Gym Jones talks about a simular ideal. When I was practicing CrossFit, I would puke on 3 workouts, and these 3 only, "Fran", "Barbara" and "Nancy". All of them involve rapid up, down movement. I never experienced any nausea following other workouts. If I had the conditioning to push myself to puke on "Fran", why couldn't I do it on "Helen"?

I do have some motion sickness. I can not read in the car and when landing, fast and hard at BIAP and KAF, I puked. This whole thought process is about how we confuse conditioning with heart, or in this case effort with a hyperactive vestibular center. Thoughts?

I agree with motion sickness part but I do find that in workouts that take less than 3 min (even if it's not fran), I can generate soooo much lactic acid during that about 1 min following I feel like I have alcohol posioning and have a great urge to vomit. I usually don't puke but the urge is there. It is only on workouts were I can go at 100% output for the entire duration - straight balls to the wall attitude. Workouts like Helen I find I go very hard but it is only 80% of a full go so I can last till the very end. Additionally, I find working out in full sun on a hot day (maybe sun stroke) can also increase the chance of puking.

I puke during barbara....i think it is the built in rest that allows me to go really hard. In the army I would puke at the crest of a long steep hill...not sure how that applies.
