That's not to say that there are no risks in running. It can sometimes cause soft-tissue injuries and stress fractures, also called hairline fractures, which result from the compounding of tiny cracks in the bone over time. It's not uncommon for such tiny cracks to appear in the bones that bear the heaviest loads, like the tibia (shinbone), but they usually heal quickly and go unnoticed. Stress fractures occur when bone damage happens suddenly, without enough time to heal. For instance, high school athletes who stop training all summer and then abruptly start attending practice every...
...good news is that there are ways to help reduce the risk of stress fracture. One method may be to simply strengthen the muscle attached to the bone. In a study published in the December issue of Medicine & Science in Sports & Exercise, researchers at 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. Why? The stronger the muscle, the greater the force it exerts on the bone; a contracting muscle exerts a bending force on the bone, like...
...recently completed her Ph.D. in exercise physiology at the University of Minnesota. She suggests adding calf workouts to your regular exercise routine but cautions that increasing muscle and bone strength is a gradual process and that having strong calves is no cure-all. But "if it can help prevent stress fractures, it's worth a try," says Popp...
...does greater income inequality lead to social problems? RW: In hierarchical societies the quality of social relationships becomes strained, and that can be stressful. Many of the effects we note spring from chronic stress, whether you are talking about obesity or mental health or the sexual development of girls stressed early in childhood...
