Eccentric release is the muscle lengthening under light load as the client eases off resistance.
It uses the lengthening phase named in 📝Eccentric, as table work rather than a training week. In 📝Resisted Soft-Tissue Release the person is already working; they let the limb move while the contact stays. It is not a diagnosis of a tear and not a claim this lengthening heals tissue. Sharp pain is a stop.
Clients feel a slow give under load. Dropping the effort to zero too fast misses the lengthening.
