Hi all,
I have a unique issue here. About 2 out of every 5 times I do Hard cardio (150-160 heart rate for 60+min) I wind up throwing up. After the work out I feel like crap too. Any ideas on what causes this problem. I notice that it occurs on an empty stomach or if I have eaten lotsa carbs 1 hr prior. I have tried all kinds of diet things to make this not happen but it still does. Am I working out too hard or something? I have been on an intensive physical training regimen for nearly 8 months now so I think I am in enough cardiovascular shape to push myself this hard. I am 36 yrs old and have a max rec heart rate of 184. I just dont see how working out at 80% of max HR can make you get sick like this.

For starters, I wouldn't recommend working out on an empty stomach. It's never a good idea. The only time I ever throw up is when I do really heavy leg days, or something like that. Never on a cardio thing. Sorry.

Neither working out on an an empty stomach or 1 hour after eating lots of catrbs is a good idea at all. I would expect to be throwing up if i did an hour of cardio near or above my lactate threshold with a belly full of carbs.

tricep exercises make me wanna heave, i havent though......yet
besides you see marathon runners being sick when the reach the end.

I don't guess I was very clear...it doesn't matter what variation/timing of eating vs not eating-either way I wind up heaving by the end of the workout. I don't understand what is going on...am I getting heatstroke or something like that were my body core temp can't cool off? I would have thought that I was adapted to this kind of working out by now.

Perhaps you should see a doctor?

I'm sure everybody is different but for some people the answer could lie in blood acidosis, which if I am not mistaken, results from the accumulation of lactic acid during really intense physcial training.
I think you can use things to help buffer your system, (phosphate maybe?) which I think is believed to help with blood acidosis during intense physical activity. I also read somewhere that lime juice would help, so maybe a drink with some citric acid?
I will see if I can find where I read some of this and post the link for you.

couldn't get the link to work, so here's the page:
We seldom go all out when we exercise. Most people will do some jogging and stair climbing. Within normal limits, these are aerobic exercises. In aerobic respiration, the body burns glucose completely in the presence of oxygen to yield carbon dioxide, water and energy. However, when the intensity of the physical exertion goes beyond a threshold, the supply of oxygen to the muscles will be insufficient to accommodate aerobic respiration.
An oxygen-independent process called anaerobic respiration kicks in to provide the extra energy. Unlike aerobic respiration, anaerobic respiration results in incomplete combustion of glucose and lactic acid accumulates in the muscles and the blood.
For most exercises, our bodies use a combination of aerobic and anaerobic respiration. When the exercising individual pushes his physical limit, the body will swing further into anaerobic territory. Lactic acid accumulates, the pH of the blood drops, causing headache, nausea or even vomitting. Unlike what most people think, these common symptoms of over-exertion are not due directly to the lack of oxygen supply to the brain. Trained individuals can tolerate lactic acid slightly better than untrained individuals, but the most important adaptation comes from heart muscle of highly trained athletes which can metabolise lactate much better than the rest of us. Remember that the problem does not lie in compromised blood supply to the brain. The culprit here is lactic acid and the good news is, besides training our hearts to metabolise lactate, we can moderate the influences of lactic acid on blood pH with the use of buffers.
In the past, coaches used to give their athletes sodium bicarbonate or baking soda solution to drink prior to their events. The rationale is that sodium bicarbonate combines with carbonic acid in the blood to form a buffer against pH changes. Effective to a certain extent, the amount of bicarnonate that individual athletes could tolerate varied widely. Many of them didn't perform too well on an upset stomach.
Nowadays, a much better tolerated buffer (not necessarily more effective than sodium bicarbonate) is widely available in various sports and energy drinks. Many people could have been consuming buffers without knowing it. The buffer of choice consists of citric acid and sodium citrate. A quick check with our local supermarkets show that on the average, 350ml of these citrate containing sports drinks cost about $2. Surprisingly, a few new soft drinks on the market also contain citric acid/sodium citrate. The latter of course, cost much less. Another supplementary buffer is phosphate. It is believed that phosphate containing drinks also help guard against blood acidosis during intense physical activity.
Do they work? I only have personal experience to rely on, but I certainly think so. As a matter of fact, I drink quite a bit of lime juice or coffee before and after training. Coffee has proven ergogenic effects and along with lime juice with a pinch of sodium bicarbonate which buffers the system, the chances of vomitting after strenuous exercise are greatly reduced.

Good info - dfly!

Dfly,
Thanks for the input--I really think the "latic acid poisoning" thing may just be the culprit since after these type of workouts I have the shakes really bad so I may be using up all of my body's glucose reserves and going anaerobic. This only has been happening recently since I have been really pushing up the intensity of my aerobic portion of workouts in preparation for a triathlon.

thinking about it i threw up after the 400 meter track at school when it was hot.
