Sports Injuries And Elastic Braces
The principles of sport medicine can be applied to the treatment of many musculoskeletal injuries which resemble sports injuries but have different causes. For example tennis elbow can be caused by carrying a suitcase, turning a screw or opening a stuck door and runner’s knee can be caused by excessive inward rolling of the foot (pronation) during walking.
Sports injuries are caused by incorrect training methods, structural abnormalities that stress certain parts of the body more than others and weakness of muscles, tendons and ligaments. Many of these injuries are caused by chronic wear and tear which results from repetetive motion stressing susceptible tissue.
The most common cause of muscle and joint injuries are incorrect training methods: The exerciser doesn’t allow for adequate recovery after a workout or doesn’t stop exercising when pain develops.
Structural abnormalities can cause a person to be susceptible to sports injuries by stressing parts of the body unevenly. For example when the legs are unequal in length, greater force is exerted on the hip and knee of the longer leg. In general, the pain disappears when the activity is stopped but reoccurs each time the same exercise intensity is reached.
Muscles, tendons and ligaments tear when exposed to forces greater than their inherent strength. They may be injured if they are too weak or too tight for the exercise being attempted
Some authors have determined favorable effects of compression stockings, tights or sleeves on venous hemodynamics, arterial perfusion, deeper tissue oxygenation and muscle oscillation with corresponding effects on lactate kinetics and muscular soreness.
Prophylactic ankle braces generally reduce the risk of injury during sports and are used in treatment of acute ankle sprain.
Many biomechanical studies have shown that prophylactic knee braces can provide 20% to 30% greater resistance to a lateral blow with the possibility that the anterior cruciate ligament is given even greater protection than the medial collateral ligament, additionally the elastic support helps to limit swelling.
Other scientific studies show that elastic calf braces may provide positive changes in performance of repeated sprints and maximal isokinetic exercise. Also they may reduce pain perception. Elastic braces with dynamic gradient compression accelerate the flow of oxygen-rich blood to the muscels to increase power and endurance and the removal of lactic acid from the muscels. This leads to an increase of stability and improves the management of body temperature and moisture.
