Running or jogging to keep fit or competition might seem like a uncomplicated exercise, yet up to 50% of all runners can get some kind of injury every year. This injury might be relatively minor and they run through it until it improves or it may be serious enough for them to have to cease running or jogging. The most frequent cause of these injuries is that the runner merely over did the running. They ran too much before the body has been given time to adapt or get used to the miles being run. Every 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 an excessive amount of load is applied before recuperation from a previous run, any damage get amplified and this could progress into an injury. Rest is equally as essential as the training runs and that is how fitness and strength is increased and is also how an injury is avoided.
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 different ways. Different running techniques will affect different tissues in a different way and affect some tissues too much, so that when running that could be enough to result in an overuse injury. For example, disorders like medial tibial stress syndrome (shin splints) may occur when the width between the foot placement when running is too narrow. Those with this problem can benefit from running with a wider base of gait. Another frequent biomechanical problem in runners is tight calf muscles. When running this makes the mid-foot (arch) of the foot to break down or overpronate and may result in a a range of conditions like plantar fasciitis tomedial tibial stress syndrome to runners knee. These runners may benefit the most from a calf muscle stretching rehab plan. The management of running injury depends on the cause and really should be directed at that cause, whether its biomechanics to training load concerns.
