Ice therapy relieves pain and slows blood flow to the injury. As a result, internal bleeding and swelling are reduced. Aerobic dance movement tends to be repetitive and pounding. Pounding of the feet is one of the most common causes of stress fractures, which are tiny surface cracks in the bones, of the foot and shinbone. Overuse injuries of the knees are caused by repetitive bending and straightening.
Knee sprains and strains are also common in aerobic dance.
The impact or twisting of the knee inward or outward causes ligaments to be stretched or torn. Hyperextending or hyperflexing the knee joint can cause injury as well. The type of floor used in aerobic dance can increase the risk for injury. High impact classes should not be conducted on concrete or tile floors. They are too hard.
