The Pain of CrossFit WODs
The agony of a CrossFit WOD may be worse than the agony of any other sport. There are many little voices to that big voice telling you to slow down. Let’s not dwell on that voice. Let’s dissect it a little. Two things pushing you to ring the quit bell are core temperature and insufficient oxygen. Read this article for more information. Another thing is pain. Some research has been done on the discomfort side of exercise. Researchers measure “perceived level of exertion.” Research on intake of Vitamin C and “perceived level of exertion” indicates taking vitamin C supplements (500 mg/day) results in a lower rating of how hard the workout was. Taking vitamin C once a day also lowered heart rates compared to people who took a placebo during a 4 week exercise program. That is interesting.
Should I take Vitamin C before a CrossFit WOD?
It might be worth trying during CrossFit WOD competitions. Low vitamin C intake is associated with higher levels of fatigue. Taking a supplement if your vitamin C intake from diet is good might not help. It hasn’t been studied yet. Vitamin C has a history of being touted as a cure-all. Cure-alls are things we should be suspicious of. Along with writers who don’t know that a preposition is not something one ends a sentence with. There is also some evidence that taking vitamin C before a challenging workout can block the body’s production of its own anti-oxidants, which might not be good.
In the meantime Vitamin C may be helpful for CrossFit WOD competitors for whom every rep counts. It should not be taken before every workout. Exercise causes the body to produce its own anti-oxidants. And these may be very important in the falling dominos of our physiology. Tweaking one thing may tweak that which is better left untweaked. As an example, taking vitamin C may result in your body synthesizing less of its own anti-oxidants. Best to eat a good diet with lots of vegetables and fruit.
