A hamstring strain or a pulled hamstring is a tear in one or more of the hamstrings muscles.
There are three hamstring muscles (Semitendinosus, Semimembranosus and Biceps femoris) which are known as the hamstring muscle group.
Strains are common in sprinters, hurdle jumpers and in all sports that involves sprinting activities, such as football and rugby. If left untreated can recur and the scar tissue contracts. People who have recurring hamstring pulls often have some imbalance in the pelvis or back that need attention.
Deep tissues massage is a very important part of treatment and prevention.
