What is the function of the hamstrings? The hamstring muscles actively bend (flex) the knee. They also act to straighten or (extend) the hip (as in the motion of moving the thigh backward). Surprisingly, these large muscles are not very active with normal walking or standing. However, they are extremely important in power activities such as running, jumping, and climbing.

Pulled Hamstring A small portion of the hamstring muscle also spans across the hip joint and is involved in hip extension. The hamstring muscle fibers gradually become tendon fibers near the knee to attach to bone. One can appreciate the thick tendon bands when feeling behind the knee joint. The hamstring muscle is balanced by the quadriceps muscles on the front of the thigh that cause the knee to extend. Together the hamstrings and the quadriceps help control power and stability of the knee joint, allowing activities like walking, running, jumping, and squatting.

Physical Therapist's Guide to  Hamstring Injuries A hamstring injury occurs when 1 or more of the 3 hamstring muscles or tendons (a type of soft tissue connecting the muscle to the bone) tear. It is 1 of the most common injuries of the lower body, particularly affecting athletes participating in sports such as football, soccer, or track. After tearing a hamstring muscle, a person is 2 to 6 times more likely to suffer a subsequent injury.

Hamstring Injuries Children very seldom suffer hamstring injuries, probably because they are so flexible. Muscle fatigue and not warming up properly can contribute to hamstring injuries. Imbalances in the strength of different leg muscles can lead to hamstring injuries. The hamstring muscles of one leg may be much stronger than the other leg, or the quadriceps muscles on the front of the thigh may overpower the hamstrings. Symptoms What does a hamstring injury feel like? Hamstring injuries usually occur during heavy exercise. In especially bad cases, an athlete may suddenly hear a pop and fall to the ground.

Anatomy Hamstring muscle injuries — such as a pulled hamstring — occur frequently in athletes. They are especially common in athletes who participate in sports that require sprinting, such as track, soccer, and basketball. A pulled hamstring or strain is an injury to one or more of the muscles at the back of the thigh.Most hamstring injuries respond well to simple, nonsurgical treatments.ehabilitation for a proximal hamstring reattachment typically takes at least 6 months, due to the severity of the injury. Distal hamstring reattachments require approximately 3 months of rehabilitation before returning to athletic activities. Your doctor will tell you when it is safe to return to sports.
