4 Types of Flerxibility

SFL   = Static Flexibility 

“Static flexibility is the range of possible movement around a joint and it’s surrounding muscles and tissues during a passive movement” ( a partner, gravity or other muscles than the ones crossing the joint provide the force needed to create the movement). Static flexibility is occasionally referred to as passive flexibility.

SAFL = Static Active Flexibility

The ability to assume and maintain extented positions using only the tension of the agonists while the antagonists are being stretched.

DMO = Dynamic Mobility/Flexibility

Dynamic Flexibility refers to the available range of motion during active movements and therefore requires voluntary muscular actions from muscles crossing that joint. Dynamic Flexibility is occasionally referred to as Active Flexibility.

STFL = Strength Flexibility

Strength flexibility is the ability to exert force with the antagonists at the range of motion of a movement, in order to control the movement and return to the start position.
