Passive Insufficiency

Follow on Youtube

Passive Insufficiency refers to inability of a multi-joint muscle to lengthen to a degree that allows full range of motion of all the joints it crosses simultaneously. An example of passive insufficiency would be short hamstrings, which results in the inability of the muscle to normally elongate to the degree that proper combined hip flexion and knee extension can occur, which is required for all sports. See active insufficiency.
