Ballistic stretches force the limb into an extended range of motion when the muscle has not relaxed enough to enter it. It involves fast bouncing movements where a double bounce is performed at the end range of movement.
PNF stretching, or proprioceptive neuromuscular facilitation stretching, is a set of stretching techniques commonly used in clinical environments to enhance both active and passive range of motion in order to improve motor performance and aid rehabilitation.uring the 1960s, the physical therapy departments of several universities began offering courses in PNF and by the late 1970s PNF stretching began to be used by athletes and other healthy people for more flexibility and range of motion.
