What does “release” mean?

Measured outcomes and proposed mechanisms are different questions.

“Self-myofascial release” is a common label for practices such as foam rolling. The name should not be read as proof that a tool breaks up adhesions or permanently changes fascia.

An outcome is not a mechanism

A review of 26 trials found that foam rolling can increase range of motion immediately in healthy adults, compared with doing nothing. It was not better than stretching. That supports a possible short-term outcome; it does not establish exactly why the change happens.

Context changes the comparison

A 2024 review comparing rolling or stretching with other warm-up activities found no significant differences in the measured range-of-motion and passive tissue outcomes. Evidence certainty was low to moderate. A practice can feel useful without being uniquely effective.

What that means for this library

We distinguish a published exercise example from evidence for a treatment claim. Results from a roller on a thigh cannot automatically be applied to a hard ball pressed into the abdomen. We link the original sources so you can inspect those differences.
