How to Rehab a Pulled Hamstring: From Strain to Sprint

Understanding the biomechanical demands of running is essential for effective hamstring rehabilitation. Most injuries occur during the late swing phase, where the hamstrings must work eccentrically to decelerate the limb. If rehab exercises don't eventually replicate these specific loads, the risk of reinjury remains high. This video breaks down a research paper that used MRI and musculoskeletal modeling to quantify hamstring loads during various strengthening exercises. By using this data, we can move away from guesswork and build a structured progression that systematically prepares the tissue for the demands of sprinting. Key topics covered: - The biomechanics of hamstring loading during the running gait cycle. - A data-driven comparison of common rehab exercises based on MRI findings. - How to utilize objective loading data to bridge the gap from initial rehab to high-speed running.
