Running for fitness or competition might appear like a simple activity, yet up to 50 % of all runners can get some kind of injury each year. That injury may be minor and they run through it until it improves or it might be serious enough for them to have to quit running or jogging. The most common cause of these running injuries is that the runner simply over did the running. They ran too much before the body is given time to adapt or get used to the distances being run. Each time that a load is applied to the body it is very important give it a rest before applying another load by going for another run. If too much load is applied before recuperation from a earlier workout, any damage get exacerbated and this could progress into an injury. Rest is equally 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 situation, 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 might be enough to cause a running injury. For example, disorders like medial tibial stress syndrome (shin splints) can occur when the width between the foot placement when running is too narrow. Runners with this condition might benefit from running with a wider base of gait. Another common biomechanical problem in runners is tight calf muscles. When running this will cause the arch of the foot to break down or flatten and may result in a numerous injuries like plantar fasciitis to runners knee. These runners may benefit the most from a calf muscle stretching rehab plan. The management of running injuries such as medial tibial stress syndrome is dependent upon the cause and should be geared towards that cause, whether its biomechanics to training load issues.
