Running might seem like a straightforward activity to take up to improve fitness. However, it is far from quite as straightforward as it might appear with some research showing that up to three-quarters of runners have an injury each year. Depending on how bad that overuse injury is and how it is treated, many runners just give up and don't continue to run. The reasons behind running injury are multifactorial but are related to issues for example doing too much running too early before letting the body to adapt to the increased degrees of activity. Bad running footwear with characteristics which do not match up those of the runners needs may also be an issue. Disorders of foot biomechanics and also the running technique may also be issues at raising the chance for an overuse injury.
An example of a running injury is anterior compartment syndrome. There is fibrous fascia surrounding muscles that support the muscles in place. If that fascia is tight, once we exercise the muscle would like to expand however that restricted fascia inhibits it. That compression inside the fascia compartment is usually painful. In anterior compartment syndrome, this involves the muscles in the front of the lower leg. The most frequent cause of this condition is what is called overstriding. In this the runner is striking the ground with their front leg too far in front of the body. To lower the foot to the ground, the anterior leg muscles have to work harder. As they work harder, the muscles expand and if the fascia will not allow it, then this results in being painful. It is going to only be painful when running and will not be painful when not running. The simplest way to deal with anterior compartment syndrome to use approaches for the runner to shorten their stride length in order that the lead foot doesn't contact the ground too far in front of the body when running.
