Hamstring injuries are common among runners and have a high rate of recurrence.1 Therefore, it is especially important to focus on isolated strengthening after injury to restore muscle function and reduce risk of re-injury.

Hamstrings work the hardest during the terminal swing phase of running, right before your foot contacts the ground. As the leg swings forward, the hamstrings lengthen and contract eccentrically to decelerate the hip and knee in preparation for foot contact.2 Therefore, it is important to have good hamstring strength in a lengthened range and make sure your strength is good both as the muscles are lengthening and shortening. Here are some general questions answered to help with recovery and reduce risk of injury.
