PNF Stretching

PNF Stretching

1. Proprioceptive Neuromuscular Facilitation

2. Designed to improve flexibility

3. Passive / Active stretching

   • Involves helping a partner

4. Stretch held isometrically

   • Held for up to 30 seconds
   • Stretch target muscles
   • Increases full range of movement

5. Muscle Spindles

   • Receptors in muscle detecting change in length of or rate at which muscles change in length
   • Activates stretch reflex
     • Mechanism preventing overstretching

6. CRAC technique - Contract, Relax, Antagonist, Contract

7. GTO (Golgi Tendon Organ)

   • Aims to override stretch reflex
   • Causes autogenic inhibition(relaxed muscles)
     • Enables greater range of movement
   • Greater movement range than initally anticipated
