School of Kinesiology Ph.D. student Kristy Popp is quoted in an article in Time magazine, "Is Running Bad for Your Knees? Maybe Not". A quote from the article reads: "Perhaps because it seems intuitively true, the notion persists that running, especially when done long-term and over long distances, is bad for the joints ... In a study published in the December issue of Medicine & Science in Sports & Exercise, researchers from the University of Minnesota found that among competitive female runners, those with larger calf muscles were less likely than runners with small calf muscles to suffer stress fractures in their shinbones."
