Fitness: How hamstrings should be trained

from The Guardian Liberty Voice

Athletes who had previous hamstrings injury have a 12 to 31 percent likelihood that they could re-injure the muscle group, according to a systematic review published in 2008 issue of North American Journal of Sports Physical Therapy. Most hamstring strains are caused by jumping, sprinting and kicking, because they involve quick deceleration or acceleration movements that could increase the chances of damaging the muscle fiber and other structures of the muscle and surrounding connective tissues. Because of the way the three hamstring muscles are structured — biceps femoris, semimembranosus and semitendinosus — rapid changes in contraction has been suggested as the primary cause for hamstring strains. How the hamstrings, as well as other muscle groups that work with the hamstrings to move, should be trained would depend on each person's goals, physical fitness and health history. more
