sometimes during our sparring sessions in bjj, some people puke & others get almost to that point where they need to sit out for a few minutes to collect themselves or even sit out the rest of the night. What is the cause of this & is there some snack you can have before training that can prevent this? maybe a bananna?
Personally, I have not puked from training but have gotten to that point a few times during my drive home. I don't eat anything for about 5 hrs prior to training (last meal is lunch at noon).
Is it caused from not enough oxygen in the bloodstream? Low blood sugar? Dehydration? Lack of electrolytes?
