According to the American Academy of Orthopaedic Surgeons, ankle sprains are one of the most common injuries in sports. Because the inner ankle is less stable, children's feet tend to turn inward after a tackle or collision on the field. Sports that involve a lot of running, jumping, physical contact and kicking pose the greatest risk for ankle injuries.
The achilles tendon connects the heel to the lower leg. Injury is more likely when the calf muscles are tight, such as in football and running. Placing too much stress on the tendon created by the tightening of the calf muscle may cause it to strain or rupture.
Long, vigorous training or improper technique can cause overuse injuries to your ankle. Stress fractures of the ankle and muscle/tendon strain can then develop.
Shin splints are an inflammation of the lining of the bone of the lower leg. According to the AAOS, improperly fitted shoes, overtraining and change of surface may place athletes at risk for shin splints.
