Has there been any followup? Athletes would be more concerned about performance in the event than the damage done. Yet, there was not one sentence or thought given to performance. Did the beneficial effects in fact enable him to train harder and more effectively? Did he perform better as a result? Hell, I can drink a liter of beer each day during training, train less hard due to the, ummm, side effects, and still show an improvement by their study. I'm healthier already for not running at all, for that matter.
