Doctors fight back against London Times article about bone growth in gymnasts
Posted December 9, 2008on:
This will be brief brief brief because I have to study biochemistry (which is clearly going very well).
On December 1st, the Times published an article citing evidence that gymnasts suffer “a broad constellation of injuries” to joints causing inflamed cartilage and stress fractures, things that could lead even to necrosis.
Anyway, some doctors wrote in from the National Osteoporosis Society to report on their own study, which shows that girls 8-17 engaged in “high intensity gymnastic training” had bone densities 13-28 percent higher than matched controls. They also didn’t find evidence of stunted growth or that gymnasts were not receiving adequate nutrition.
Overtraining is a real risk in gymnastics because of the early start age. You don’t see many football players being home-schooled. But honestly, I haven’t read the American study, and media reports about studies tend to be misleading at best. In either case, I think it’s telling that they then go on to say that “Previous studies have suggested that the rate of injury in gymnastics is almost as severe as that in contact sports.” Almost as severe? Sounds to me like gymnastics is still better!
On the other hand, one should also be skeptical of the other study (and of any study that one hasn’t read — someone recently found that some massive percentage of medical studies were misreported in the media). Naturally, the “stunted growth” question is a sticking point in the gymnastics community — it’s the classic chicken-or-egg question: which came first, gymnastics, or short height? But there is conclusive evidence that high-level sports delay puberty, and I think that suggesting that elite-level gymnastics has no effect on development is laughable.
And finally a place to sneak in this tidbit: while Chellsie Memmel has been on her fruit-and-chicken diet, what has Beth Tweddle been eating? According to this article, lunch might be lasagna, spaghetti bolognese or sweet-and-sour chicken. Dinner could be soup-and-sandwich or a “chicken and bacon salad.” It’s never been clear to me that the level of intensity and craziness of American gymnastics has reached across the pond, and on that note, who were the subjects of the NOS study? It’s not clear that British gymnasts have been subjected to the same harsh diets we see in some American gyms, and certainly former Soviet gyms, so it’s not clear to me how translatable the findings might be. Certainly it’s interesting that the positive findings come out of Britain while the negative ones come out of the the United States.
