But now it’s time to tackle that other fun aspect of tough workouts, throwing up.
It’s a feature of almost every sport that I like that people sometimes barf. (I have teenagers at home, including teen athletes, so I know all sorts of good euphemisms but I’ll stick with “barf,” “vomit,” and “throw up.”)
CrossFit has a metal puke bucket in the corner, mostly as a joke. So too does the rowing club. And of course, the velodrome. Of course.
It’s sort of a joke but also sort of not. Vomiting does happen. It’s certainly happened to me on the bike.
“Intense exercise has a number of effects on the body. As well as raising metabolism and burning fat, it can also cause dehydration, dizziness and nausea. Whether you do cardiovascular exercise or strength training, it is not uncommon to throw up during or after a workout.” Read How to Prevent Throwing up when Exercising
I was reminded of all this this morning doing 200 m sprints x 10 on the erg, aka rowing machine, at CrossFit.
I was busy paying attention to how I felt about pain in response to commentators who think you really can’t say truthfully you enjoy painful intervals. And I’m right. At the fifth sprint, I had that silly smile on my face that makes other people question my sanity. Yay endorphins. I also had done a great job of keeping my times constant through the first five efforts.
Times ranged quite a bit, from the high 30s to the low 50s. For my first five 200 m intervals I was around 42 seconds.
But after five, my times started to go up. I stopped smiling. And by seven I was starting to think I might throw up. I didn’t. But I didn’t manage to eat again until lunch.

High intensity interval training, in particular, brings about a bad combo. Lactic acid on the one hand, and blood going to your limbs rather than your digestion system, on the other. There are are reasons to skirt the edge of pukiness. In part, your body learns how to cope and recover and that’s important.
I’m not sure about the gallows humour around throwing up after a workout. But like the issue of peeing during workouts, I think it helps to know you’re not alone. Going hard, whether cycling, rowing, running, or swimming can bring it on and there’s no reason to be ashamed or proud about it.
“A 1992 study in the International Journal of Sports Nutrition found that 93 percent of endurance athletes experienced some type of GI symptom (e.g., acid reflux, nausea, and vomiting) during their races.” See Techniques to Prevent Nausea and Vomiting Before, During, and After Racing.
It’s an issue with any form of High Intensity Interval Training but your body does adjust. From Precision Nutrition’s All About High Intensity Interval Training (HIIT):
“Most every high intensity physical activity is a state of “crisis” in the body. It endangers oxygen supply to tissues, increases body temperature, reduces body fluids and fuel stores, and causes tissue damage.
Intense exercise creates endocrine and defense reactions that are similar to those elicited by low blood oxygen, high blood carbon dioxide, acidosis, high body temperature, dehydration, low blood sugar, physical injury and psychological stresses.
Hormonally, your body basically freaks out. Then it brings out the big guns to deal with the problem. High intensity exercise stresses the body so much that it’s forced to adapt.
As Nietzsche gasped during a 20-rep squat set, “That which does not kill me makes my quads bodacious.” (It makes more sense in German.)”
