They start at the bottom of the pelvis and end near the top of the lower leg • The hamstring muscles are important as they function to both actively bend the knee and extend the hip joint (as in the motion of moving the thigh backward) • The hamstring muscles are not used much while walking or standing, but they are very active during power activities that involve bending the knee, such as climbing, jumping, and running • During a hamstring injury, one or more of these muscles gets overloaded, and might even start to tear. • A hamstring injury can range from a minor strain, classified as grade I, to a major rupture, classified as grade III CAUSES A hamstring injury is caused by physical activities that stretch the hamstring muscles beyond their limits. This may include rapid acceleration activities when running or initiating running activity. Hamstring injuries are relatively common in sports such as soccer, football, track, and field event, baseball, and tennis. A hamstring injury can also occur more gradually, or during slower movement that overstretches the hamstring.
