PNF Stretching and Plyometrics - PE Magazine

In the article they refer to Proprioceptive Neuromuscular Facilitation as

• A stretching technique usually involving 2 people which increases flexibility

• A training programme involving muscle spindles and golgi tendons that create autogenic inhibition

• A combination of static and passive stretching that is an effective way to increase flexibility

• A plyometric training to help athletes develop the power they need for explosive force

How is Proprioceptive neuromuscular facilitation performed?

The "all or none (nothing) law" is mentioned here to explain

• mainly the isometric contraction phase of the PNF

• mainly the initial passive stretch phase

• the overall process of PNF

• The all or none(nothing) law is not mentioned in the article

What is the GTO

• Great Tension Order involved in the stretch reflex

• Golgi Tension Organ - involved in the stretch reflex

• Golgi Tendon Organ - activated when a muscle is relaxed

• Golgi Tendon Organ - activated when a muscle is stretched or contracted isometrically

Explain in your own words what is CRAC and give a practical example

Plyometrics is

• The initial phase of the PNF

• A powerful stretching technique

• A type of power training

• None of the above
