Many elite runners get acupuncture. Here’s an article in ‘Runner’s World’ in which the author describes first getting acupuncture after competing in a marathon in Japan, where it was made available to every participant in the race. He says that he used acupuncture to recover from an injury and as regular part of his training regimen. The article says that acupuncture is as widely used as massage by Asian athletes, and while some elite American runners use it to for existing ailments, it “may prove most beneficial as preventative medicine”.
I posted before about acupuncture for sports performance and recovery, and there are links to some research that show that it’s a good idea there.
