If you run, you know all too well that sports-related injuries are just part of the territory-about 60 percent of runners report getting injured in the past year. And that number can creep up to as high as 80 percent, depending on things such as what surface you're running on, the average time spent running, and exercise history or experience. This is according to a study published in the BMJ and it's not just scrapes, bruises, or black toenails we're talking about.
