Massage is the general term used for rubbing, pressing and manipulating muscles, skin, tendons and ligaments. Massage consists of various techniques, which range from light strokes to deep pressure.
The repetitive movement that is associated with many types of exercise, e.g.; running, swimming, boxing and horse riding, cause your muscle fibres to gradually become shortened. This, unfortunately, makes you more prone to injury, due to the compressed muscle fibres and reduced blood supply to the muscles.
