Eccentric Heel Drops: Alfredson’s Proven Protocol for Achilles Recovery

Alfredson’s eccentric heel drop protocol has become a cornerstone in the treatment and prevention of stubborn Achilles tendon injuries in runners. This article delves into the science and strategy behind the method—unpacking how slow, deliberate heel-lowering exercises can stimulate collagen regeneration, promote proper tendon alignment, and rebuild strength where it matters most.

    When reading this article, it is important to understand we are talking about eccentric heel drops not eccentric heel raises. There is a very important distinction between the two.

    Eccentric Heel Drops – A Complete Guide

    As a runner, you often succumb to various injuries throughout your running career. Many hours are spent focusing on exercises and rehabilitation to keep your body in check. Thus, eccentric heel drops are one of those exercises you probably know all too well.

    Mainly used to help treat Achilles tendonitis, it has been proven to be very successful in treating other chronic Achilles tendon injuries.

    As you run and push your toes off the ground, power is coming from the Achilles tendon. This means the faster and longer you run, the more stress is placed on the tendon. This stress can be upward of 3 times your body weight. So, eccentric heel drops should be included in your preventative maintenance plan. Whether you are injured or not.

    Performing heel drop exercises help to strip away misaligned tendon fibers. This helps to lay new fibers that are aligned better to the collagen in the tendon. It is also important to note that it is common to feel light to moderate pain during these exercises. Some light to moderate pain is a positive sign in the healing process.

    Once you are able to do the heel drops pain-free, you need to progressively add weight to the exercise. This can be done by wearing a backpack or using lite leg weights.

    Remember any kind of strengthening regime shouldn’t be performed before a run. This will fatigue the area of deficiency more, and possibly cause more noticeable or severe symptoms.

    Alfredson’s Eccentric Heel Drop Protocol

    If you are struggling with Achilles tendon issues, following Alfredson’s eccentric heel drop protocol can help strengthen and align the tendon. Alfredson created an Achilles recovery plan that included three innovations that changed the way we thought about heel drops.

    It’s not necessarily a bad thing if the pain in your Achilles increases. This could be a sign of the normal healing process. Heel drops should always be performed with straight or bent legs. 180 repetitions should be performed every day for a period of 12 weeks.

    Alfredson’s eccentric heel drop protocol helps to increase tendon volume and stimulates collagen production just like other rehab programs. The main difference from other heel drop programs is the number of repetitions it includes. This is much more repetitions than other Achilles rehab protocols suggest. The Eccentric exercise involves dropping the heel to the ground in a slow and controlled way. While doing so, the muscles in the calf are contracting at the same time as they are lengthening.

    However, the routine must be done for 3 months (12 Weeks) without fail and you may suffer some discomfort or pain during this time. Just remember, you are also most likely to see their injury getting worse before it gets better.

    Recently a study was released over a 5-year period, where patients with Chronic Midportion Achilles Tendinopathy followed Alfredson’s protocol for 3 months (12 Weeks). They found that after a 5-year follow-up, 39.7% of the patients were completely pain-free. While 48.3% of others in the study had received one or more alternative treatments.

    Based on this study, improvements of symptoms can be expected longer-term, but some mild pain may still remain after following the protocol for 3 months. (https://bjsm.bmj.com/content/46/3/214)

    Achilles Tendon Heel Drop Exercises

    Achilles Tendon Heel Drop Exercises

    Although nearly all heel drop exercises follow the same theory, the difference lays in the protocol in which you follow. It is important not to overdo the exercises in the beginning, once you feel comfortable doing them start to increase the amount of repetitions.

    Gastrocnemius Heel Drop

    First, stand on a step with one foot only. Raise the heel up and lower the heel slowly. Do this until the foot is parallel to the ground. Make sure you keep the leg straight and use the uninjured leg to help push back to the starting position.
    This exercise should be completed three times daily (15 repetitions) for a period of 12 weeks.

    Soleus Heel Drop

    Performed in the same way as the gastrocnemius heel drop exercise. But you must bend your knee at 45 degrees (like a half squat).

    This exercise can be performed up to three times daily with a total of 15 repetitions each time.

    Alfredson’s Heel Drop

    Start by using a stepper (or stairs). Stand with both legs on the stepper with the focus on the forefoot of the injured leg. Push up onto the toes. Slowly lower the injured leg’s ankle down below that of the stepper. (with the uninjured leg removed from the stepper). Place the uninjured leg back of the stepper to help you bring the foot back to the forefoot position. This can be both done with a straight and 45 degrees bent knee.

    This exercise should be completed 4 times daily and focus on sets of 3×15. This will give you a total of 180 repetitions daily for a 12-week period.

    Pain ReductionCan lessen chronic Achilles pain over time by improving tendon function.
    Injury PreventionIntegrating heel drops into your routine may reduce the risk of future injuries.
    Effective RehabilitationOffers a structured, evidence-based approach to recovering from Achilles tendonitis.

    Should You Do Eccentric Heel Drops With or Without Shoes

    Eccentric heel drops should always be performed with shoes. Stay away from wearing minimalist shoes as they add more tension to the tendon.It is recommended to use a normal running shoe with an average heel to toe drop. This will help prevent any tension on the tendon and provide some grip to the forefoot when lowering the heel. Stay away from performing heel drops barefooted as these often make the patient overextend the Achilles by again, adding more tension to the tendon.

    Frequently Asked Questions

    Heel drops involve lowering the heel in a slow, controlled motion using eccentric muscle contraction. Heel raises are the opposite—pushing the heel upward, which is concentric. The two serve different purposes in rehab and strength training.
    It’s a 12-week program involving 180 heel drops per day, performed in sets of 3×15 with both straight and bent knees. The focus is on slow eccentric movement to strengthen and heal the Achilles tendon.
    Alfredson’s protocol recommends doing the exercises 4 times a day. Each session includes 3 sets of 15 repetitions for both the straight-leg and bent-knee variations.
    Yes, light to moderate pain is expected and often considered a sign that the tendon is responding to the exercise. Sharp or worsening pain, however, should be addressed with a healthcare professional.
    Once you can complete the heel drops without pain, gradually add resistance—like a backpack or light ankle weights—to continue progressing.
    Yes. Regularly incorporating heel drops can strengthen the tendon and reduce the risk of future injuries by improving tendon structure and resilience.
    Yes. A 5-year follow-up study showed that 39.7% of patients became completely pain-free after completing the 12-week protocol, with many others reporting long-term improvements.

    Conclusion

    In essence, Alfredson’s eccentric heel drop protocol emerges as a transformative approach for both rehabilitating and preempting Achilles injuries. With its slow, deliberate eccentric movements, this method not only prompts the realignment of tendon fibers and stimulates collagen production but also sets a foundation for enduring tendon strength. Discomfort—often light to moderate—is a natural, even encouraging part of the process, signaling that the tendon is being properly loaded and stimulated.

    Yet, the journey is not one of rapid leaps but of measured, incremental steps. Gradually increasing resistance and respecting the body’s feedback are paramount; the path to recovery is paved with patience, technique, and persistent effort. For those contending with chronic Achilles tendonitis or seeking to safeguard against future injuries, integrating eccentric heel drops can be a game changer in your training regimen.

    Ultimately, the secret lies in consistency and understanding that true healing unfolds over time. With professional guidance and a steadfast commitment to gradual progression, every controlled heel drop brings you closer to a future of stronger, more resilient running.
