Mobility & Foam Rolling
Move · Flexibility & Mobility · Movement, Typed Supps
It works on your nervous system rather than on the tissue you think you are breaking up.
Stage by stage
- Start (Pressure and tension applied): Rolling or stretching applies mechanical pressure and tension to muscle and connective tissue.
- During (Nervous system reduces guarding): The change comes from reduced nervous system output and increased stretch tolerance, not from deforming the tissue.
- Immediately after (Range improves temporarily): Range of motion improves measurably, though the effect typically fades within about an hour.
- Following on (Movement retains the gain): Actively moving through the newly available range is what converts a temporary change into a lasting one.
Muscles trained
- Primary: hamstrings, quads
- Secondary: lower back, calves
Intensity
2.3 METs (Stretching, mild).
Time to effect
- Immediate: Range of motion improves right away, then fades within about an hour unless reinforced with movement.

Common myth
“Foam rolling breaks up scar tissue and releases fascia.” In reality: The forces involved are far too small to deform fascia — the measurable effect comes from your nervous system reducing muscle tone and increasing stretch tolerance.
