Learn how to optimize hamstring recovery for peak performance with insights and key Q&A from Brian Duncan, PT, DPT, OCS, SCS.

A: Fascial length is not necessarily more important than strength, but the body adapts from training, loading, and sprinting. However, sprinting alone is insufficient for optimal hamstring recovery.

A: Currently, there is no way to palpate fascial length. It can only be observed on MRI or ultrasound as imaging techniques improve. An NFL-funded trial is ongoing, examining hamstring injuries and investigating various factors with imaging across several colleges.

A: Varying the amount of knee flexion or extension can increase hamstring length and load depending on the specific area of the hamstring. Training hip extension can place more load on the proximal hamstring tendon. Most hamstring injuries occur at the myotendinous junction (proximal), while injuries within the muscle belly tend to heal better.

A: The higher the level of competition, the more complex the situation becomes, often involving “more cooks in the kitchen.” This raises questions about collaboration between different coaches and the athletic trainer. Communication and planning can be challenging in these scenarios, impacting hamstring recovery.

A: High-intensity sprinting is considered most important, but a lack of planning may be an issue. There is a significant load difference between an 80% sprint and a 100% sprint, with a substantial increase in eccentric load at maximum effort. The length the hamstring travels between 80% and 100% sprint is no different. A gradual progression back into previous activities is often necessary for effective hamstring recovery. Running more than nine sprints in a session can lead to further hamstring injury.

A: AI is only as effective as the user and the questions asked. For example, it can build a maintenance program. When asked to include high-speed running and eccentric loading, it then asked if a weekly microcycle was needed. Hopefully, it will not replace athletic trainers’ jobs but instead help them to excel at them, especially in optimizing hamstring recovery.

A: Athletic trainers should start eccentric training early (at a pain level less than 4/10) and incorporate sprinting (running) as soon as possible. It is also crucial to communicate with coaches to target at-risk position groups with maintenance plans throughout the season and to incorporate banded Nordic hamstring curls to maximize range of motion.

A: Maintenance programs are vital throughout the season to prevent recurrences and soft tissue injuries. During SAC camps, the key is to prevent overtraining and identify athletes who don’t self-regulate. Sprint training should occur early in SAC camp or during the day’s workout before lifting. For in-season maintenance, hamstring work should be incorporated on match day and two days after, ideally 3-4 days before the next match day.
