“Overall, the study findings showed a significant reduction in VO2max levels a week post- BNT162b2 vaccination among recreational endurance athletes. Further research must be conducted to determine the clinical significance of the observations.”
Interesting conclusion. Seems there is a lot more research needed going forward on lasting impact and athletes deemed higher than “recreational”.
I ran like crap for a week after my shots and could only run half my normal mileage. But there was some kind of super-compensation effect afterwards, and I PR'd 2 weeks later.
This should get folks to the actual paper:
It's pretty interesting, and I wonder what the mechanism is. Does anyone know if heightened inflammatory or immune responses cause a decrease in VO2max? I know of a lot of publications discussing the effect of exercise on inflammation and immunity, but not going the other way.
Maybe one of the shots was special sauce
On the other hand, one of our best athletes got actual covid mid xc season. Basically ruined the season. Unclear if the athlete will regain form during indoor.
So that showed a 3.7% drop in VO2max for a week after vaccination, based on a few people who had really bad outcomes.
On the other hand, you can get covid, and have a 5% drop in VO2max lasting at least two months after you've "recovered."
Unless it's sub 15 I don't care.
