In today's time runnig is one of the most the most widespread and most popular form of physical activity. People around the world enjoy this activity because it is easy to implement and has many health benefits. It has a beneficial effect on the cardiovascular and immune system, in the prevention of diabetes, osteoporosis, etc., and also, like other physical activities, improves the overall health of the individual, both physically and mentally. Running is a monostructural cyclic activity and is seemingly very easy, but precisely because of the continuous repetition of the same movements, repeated impact force, occure lower leg injuries. Overexertion injuries in the lower leg area include m. Tibialis posteriora syndrome, chronic anterior fascial space syndrome, tibial periostitis, and fatigue fracture. Running shin most commonly occurs in long-distance athletes, soldiers, ballet dancers, and recreational runners. The appearance of pain in the middle part of the lower leg is characteristic of a tibial fatigue fracture, and along the antero-lateral side of the lower leg it is a sign of chronic fascial space syndrome. Pain on the medial side of the lower part of the lower leg indicates m. tibialis posteriora syndrome, and thickening of the tibia indicates tibial periostitis. Regardless of the cause, in the prevention of running shin, it is important not to make mistakes in training methodology, muscle dysfunction and insufficient flexibility, in sports shoes, running mats, and running biomechanics. Immediately after the diagnosis, it is necessary to reduce physical activity or completely eliminate it. In addition to this protective measure, anti-inflammatory therapies should be administered, from ice packs, elastic bandages, lymphatic drainage, to analgesics and anti-inflammatory drugs (if necessary). This is followed by physiotherapy treatment, from electrotherapy, ultrasound, laser, to magnetotherapy. At this stage, kinesiotherapy treatment begins, exercise. Exercise streches the muscle of the lower leg, and performs certain exercises to strenghten them.
