Sports Med 2

 Proprioceptive  Neuromuscular  Facilitation  First used by physical therapists for treating patients who had various types of neuromuscular paralysis Now used as a stretching technique to increase flexibility  Stretching techniques that involve combinations of alternating contractions and stretches  Used in rehabilitation to facilitate strength and increase ROM

ADVANTAGESDISADVANTAGES  Increase muscular flexibility  Increase ROM  Exercises require a partner  Exercises require expertise PNF involves 3 types of Movements Flexion/Extension Abduction/Adduction Internal/External Rotation

 Passive The degree to which a joint may be passively moved to the endpoints in the ROM No muscular contraction is involved  Active The degree to which a joint can be moved by a muscle contraction

 Isometric Means to contract a muscle statically without changing its length This contraction is referred to has “hold”  Concentric The muscle shortens while contracting against resistance This contraction is referred to as “contract”  Passive stretches Referred to as “relax”

 Hold-relax Passive stretch – for 10 sec. Athlete is instructed to “hold and not let leg move” for 6 seconds  Athlete resists movement which creates isometric contraction Athlete relaxes Passive stretch held for 10 sec. Repeat 3 times  Contract-relax Passive stretch –hold for 10 sec Athlete isotonically pushes against resistance from partner-6 sec Athlete relaxes Passive stretch applied and held for 10 sec. Repeat 3 times  hold-relax- with contraction Athlete moves body part to point of resistance and is told to “hold” Muscles are isometrically resisted by partner for 6 sec. Athlete relaxes- Athlete moves body part into farther ROM- stretch 10 secs
