Sports massage is a lot like it sounds. It is a treatment type that focuses primarily on facilitating athletic actions. It can be used in preparation of an event or competition, after such an event, during training for competition or in rehabilitation from a sports-related injury.
One of the main uses of sports massage is to make sure muscles do not tighten up or form knots. Knots in muscle can lead to pulls, strains and tears, and obviously pain and discomfort. By keeping muscles relaxed before competition you can avoid injuries during an event.
