Eccentric Loading: How It Affects and Treats Tendinopathy




Eccentric loading is a therapeutic approach commonly used in the management of tendinopathy, which is a condition characterised by pain, swelling, and dysfunction of a tendon. This technique has gained popularity due to its effectiveness in promoting tendon healing and reducing pain in various tendinopathies, such as Achilles tendinopathy, patellar tendinopathy, and lateral elbow tendinopathy.


The science behind eccentric loading for tendinopathy revolves around the principles of exercise physiology, tissue adaptation, and mechano-transduction. It is important to note that the exact mechanisms underlying tendinopathy are still not completely understood, but researchers have made significant progress in elucidating the benefits of eccentric loading for this condition.

  1. Stimulating Tendon Healing: Eccentric loading focuses on exercises that emphasise the lengthening phase of muscle contractions. This type of loading creates tension within the tendon, which, when controlled and gradual, can stimulate the production of collagen, the primary structural protein of tendons. Collagen synthesis is a critical part of the healing process in tendinopathy.

  2. Mechanical Overload: The principle of mechanical overload is key to the science behind eccentric loading. Tendons are dynamic structures that adapt to changes in mechanical stress. By exposing the tendon to controlled and progressive eccentric loading, it helps to "overload" the tissue. This overload prompts the tendon to adapt and become more resilient, which is crucial for recovery.

  3. Neovascularisation: In tendinopathy, there is often a reduction in blood flow to the affected area of the tendon. Eccentric exercises can increase blood flow and stimulate neovascularisation, which is the formation of new blood vessels. Improved blood flow can provide essential nutrients and oxygen to the injured area, promoting healing.

  4. Pain Reduction: Eccentric exercises can also help alleviate pain associated with tendinopathy. Although the precise mechanisms are not fully understood, some studies suggest that eccentric loading may reduce pain by desensitising the pain receptors in the tendon and altering the perception of pain.

  5. Matrix Remodelling: Eccentric loading can stimulate the remodelling of the extracellular matrix within the tendon. This remodelling process helps reorganise and strengthen the collagen fibres in the tendon, improving its structural integrity and reducing the risk of re-injury.

  6. Biomechanical Changes: Over time, eccentric exercises can lead to biomechanical changes in the way the affected tendon functions. These changes often result in better load distribution and a more efficient transfer of forces, reducing the risk of recurrent tendinopathy.

  7. Patient Compliance: Eccentric loading exercises are typically well-tolerated by patients because they often produce less pain compared to other exercises. This increased compliance and reduced pain allow patients to engage in a sustained exercise program, which is essential for tendon healing.

It's crucial to note that eccentric loading should be prescribed and supervised by a healthcare professional to ensure that the exercises are tailored to the specific tendinopathy and the individual's needs. The intensity, frequency, and duration of the eccentric loading program should be carefully adjusted based on the stage and severity of the condition.


The science behind eccentric loading for tendinopathy is rooted in the principles of tendon adaptation, collagen synthesis, improved blood flow, and pain reduction. It is a valuable and evidence-based approach for managing tendinopathy and promoting tendon healing. Patients should consult with healthcare professionals to create a personalised eccentric loading program tailored to their specific condition.
