Sports Injuries to the Foot - Podiatrist in Chelmsford and Newburyport, MA br br Sports Injuries br Martial arts and kick boxing: br A variety of injuries can occur as a result of martial arts and kick boxing. These include plantar fasciitis, Achilles tendonitis, sesamoiditis, and ankle sprains. Stretching is recommended for a minimum of 15 minutes before performing any kicking or punching. br Aerobics: br Proper shoes are crucial to successful, injury-free aerobics. Shoes should provide sufficient cushioning and shock absorption to compensate for pressure on the foot many times greater than found in walking. They must also have good medial-lateral stability. Impact forces from aerobics can reach up to six times the force of gravity, which is transmitted to each of the 26 bones in the foot. br Team Sports: br Activities such as football, basketball, soccer, field hockey and lacrosse often lead to ankle and big toe joint injuries as a result of play on artificial surfaces.
