Hamstring Injury

Sudden pulling or tearing pain in the back of the thigh during sprinting or an extended stride.

Understanding Hamstring Injury

The hamstring muscle or tendon can be injured when rapid contraction and lengthening exceed its capacity. Runners may also develop longer-lasting proximal tendon pain near the lower buttock.

Treatment Direction

Limit Speed Early

Stop sprinting and overstriding while maintaining walking that does not cause a limp.

Assess Muscle and Tendon

We assess injury location and strength difference, with ultrasound or MRI for a suspected major tear.

Rebuild Length and Speed

Progress from isometric work to strength at longer muscle lengths and then high-speed running.

Return-to-Running Criteria

Fast walking and easy jogging are pain-free

Side-to-side knee flexion strength is close

Return through jogging, steady running, acceleration, and then sprinting

When to Seek Evaluation Promptly

Prompt evaluation is needed for a loud pop, extensive bruising, marked weakness, or severe pain near the lower buttock suggesting an avulsion injury.

Do not put off persistent pain. Have it checked.
