Does Loading a Tendon With Heavy, Slow Reps Actually Reverse Tendinopathy Better Than Rest?
Published July 10, 2026
The old advice for a cranky patellar or Achilles tendon was to stop moving it and wait. The research has quietly buried that idea. Håkan Alfredson's foundational work on chronic Achilles tendinopathy showed that a twelve-week program of heavy eccentric loading produced meaningful pain reduction and return to function in patients who had been sidelined for months, many of whom had been queued up for surgery (see [1]). Rest did not do this. Load did. The mechanism matters: a tendon is not inert rope, it is living collagen that remodels in response to mechanical strain. Take the strain away and the tissue does not heal so much as stall.
