" Those runners who’d popped over-the-counter ibuprofen pills before and
during the race displayed significantly more inflammation and other
markers of high immune system response afterward than the runners who
hadn’t taken anti-inflammatories.
The ibuprofen users also showed signs
of mild kidney impairment and, both before and after the race, of
low-level endotoxemia, a condition in which bacteria leak from the
colon into the bloodstream."
But the news gets worse yet:
" Athletes at all levels and in a wide variety of sports swear by their painkillers. A study published earlier this month on the website of the British Journal of Sports Medicine found that, at
the 2008 Ironman Triathlon in Brazil, almost 60 percent of the racers
reported using non-steroidal anti-inflammatory painkillers (or NSAIDs,
which include ibuprofen) at some point in the three months before the
event, with almost half downing pills during the race itself."
But that' s not all, the news gets even more worse for athletes who pop a lot of painkillers when training:
"The painkillers also blunt the body’s response to exercise at a deeper
level. Normally, the stresses of exercise activate a particular
molecular pathway that increases collagen, and leads, eventually, to
creating denser bones and stronger tissues. If “you’re taking ibuprofen
before every workout, you lessen this training response,” Warden says.
Your bones don’t thicken and your tissues don’t strengthen as they
should. They may be less able to withstand the next workout. In
essence, the pills athletes take to reduce the chances that they’ll
feel sore may increase the odds that they’ll wind up injured — and
