Running for good health or competition may appear like a easy exercise, however up to 50 % of all runners can get some type of injury each year. This injury might be minor and they run through the injury until it gets better or it can be serious enough for them to have to give up running or jogging. The most common cause of these running injuries is that they merely over did it. They ran too much before the body is given a chance to adapt or get used to the miles being run. Each time that a load is applied to the runner it is essential to give it a rest before applying another load by going for another run. If too much load is applied before recovery from a earlier workout, any damage get amplified and this may progress into an injury. Rest is just as important as the training runs and that is how fitness and strength is increased and is also how an injury is averted.
In addition to the too much too soon issue, biomechanics also has a role. This is the way that we run and different athletes do it in a different way. Different running techniques can load different tissues in a different way and load some tissues too much, so that when running that may be enough to cause . For example, injuries such as medial tibial stress syndrome (shin splints) may occur when the distance between the foot placement when running is too narrow. Runners with medial tibial stress syndrome could benefit from running with a wider base of gait. Another common biomechanical problem in runners is tight calf muscles. When running this causes the mid-foot (arch) of the foot to collapse or flatten and can result in a numerous conditions such as plantar fasciitis to runners knee. These runners may benefit the most from a calf muscle stretching program. The treatment of running injuries depends on the cause and should be directed at the cause, whether its biomechanics to training load issues.
