Here's another twist on doping in athletes . . .
. . . recall that in previous blog posts I explored several types of doping: blood doping, drug doping, genetic doping, and so on. In a recent article on the placebo effect that I read in Scientific American Mind I learned about a new kind of doping . . . that is legal, apparently.
Morphine is on the banned list for athletic doping. An advantage of using morphine would be to reduce pain during an intense athletic event--pain that could reduce performance. According to a sidebar in the article, studies show that if an athlete is given morphine during training (which is legal), then abstains long enough for the morphine to clear the system, then takes a saline injection (placebo) on the day of competition, the athlete experiences reduced pain.
If this turns out to work consistently, with many different athletes, I wonder if use of drugs during training will be banned.
For more on doping, see my article at The A&P Professor website.

Here's the research behind the "doping" by placebo concept:
