You have two major calf muscles: the gastroc and the soleus. The Achilles tendon originates from the soleus and merges with the gastroc to insert down on the heel bone. The Achilles Tendon is one of the largest and strongest tendons in the human body.
When we run, the Achilles Tendon absorbs 12x bodyweight, which is why tendinopathy is so common amongst runners.
Tendinopathy:
Tendinopathy refers to any pain or dysfunction of a tendon. If you have any of these symptoms, it is likely you have Achilles Tendinopathy:
- Pain with squeezing the tendon or point tenderness at the heel bone
- Pain with loading, and more pain with hopping or jumping
- Increased pain with calf stretch
- Decreased calf strength or ability to push off when running or walking
- Swelling at the tendon area
- Minimal pain at rest
- Morning stiffness with first steps
- Feels like it warms up with activity
Risk Factors:
- Hill Running
- Speed work
- Poor recovery
- Change in footwear
- Change in training volume or intensity
- Excessive ankle range of motion
- Limited ankle range of motion
- Decreased plantarflexion strength
Management of Tendinopathy:
Achilles Tendinopathy can take anywhere from 6 weeks to a year to resolve, with
lingering symptoms that may occur for years if not addressed. Treatment for
tendinopathy will include temporarily reducing or removing plyometric activities (including running), minimizing compression of the tendon, and heavy resistance training. Full rest is NOT indicated for tendinopathy. Full rest will decrease the tendon’s capacity and increase the likelihood of injury or re-injury.
