Hamstrings play a very complicated role in the action of running, which makes them extremely prone to injury. Because of this, hamstring-related injuries are one of the most common problems experienced by rugby players. In this article, we answer some of the most commonly asked questions rugby players have after sustaining a hamstring injury.

What are the hamstring muscles?

  • A group of three muscles:
    • Semitendinosus
    • Semimembranosus
    • Biceps Femoris

What do hamstring muscles do?

  • They bend the knee and extend the hip. Functionally, the hamstring muscle complex has three basic roles with running:
    • Slowing the striding leg down as it approaches the ground
    • Extending the hip and propulsion of the body forward
    • Assisting the calf muscle as it helps to move the knee.  
  • They have to work both concentrically (shorten) and eccentrically (lengthen) at various times when running.   

What causes hamstring tightness?

  • Sitting puts the hamstrings in a shortened position which can cause tightness over time. The hamstrings also have to produce large amounts of force which can shorten the muscle over time.

 What is hamstring tendinopathy?

  • This used to be categorised as a form of tendonitis, which implies an inflammatory condition. However research has shown that there is no sign of inflammation within an affected tendon. These conditions are now called tendinopathies. The collagen tissue within the tendon degrades and will produce pain. Research shows that to treat a tendinopathy, the tendon must be put under load, particularly eccentric loading. This involves the muscle and tendon working as the muscle lengthens. An example of this for the hamstrings is a Nordic curl.


What causes pain where the hamstrings meet the glutes?

  • This can be due to a tendinopathy of the common origin of the three hamstring muscles. They all form into one tendon which inserts onto the pelvis.

What causes pain where the hamstrings meet the knee?

  • If pain is on the inside of the knee, it can be a tendinopathy of semitendinosus or semimembranosus (2 of the 3 muscles of the hamstring group). If it is the outside of the knee, it could be a biceps femoris (another muscle in the hamstring group) tendinopathy.

How do hamstring injuries occur?

  • Studies have shown that the hamstring muscle group reaches peak elongation and is most active during the late swing through the mid-stance phase of running. Thus, the hamstrings reach their maximum length while attempting to forcefully work eccentrically and switch functions to immediately produce a concentric contraction, which makes the terminal part of swing phase the most vulnerable for injury. 

What is the recovery time for hamstring injuries?

  • For minor hamstring strains, it can be 3-6 weeks. For more severe hamstring injuries it could be 6-12 weeks. For more information on how to recover from hamstring injuries, check out our Guide to Recovering from Hamstring Injuries.
