Module 11 - Stretching Flashcards
What is the primary reason for stretching?
To increase range of motion
What is the Golgi Tendon Organ?
The GTO is a nerve receptor located at the junction of a muscle and tendon and detects the degree of tension generated by the muscle contraction.
What is a Muscle Spindle?
Muscle spindles are stretch receptors that signal the length and changes in the length of muscles.
What are the four primary types of stretches?
Static, dynamic, ballistic, and proprioceptive neuromuscular facilitation
How is a static stretch performed?
An individual performs and holds a stretch at the end range of motion and holds it for 30 seconde or longer.
What happens when you hold a stretch for 40 seconds or longer?
The muscle spindles become accustomed to the new increase in length and reduce the signals sent to the spinal cord to tell the muscles to contract.
How is a dynamic stretch performed?
An individual moves a body part at a controlled speed through a range of motion that mimics the motions performed while running.
How is a ballistic stretch performed?
Similar to the dynamic stretch, but the movement is done with momentum to stretch past the current ROM limit.
How is a proprioceptive neuromuscular facilitation stretch performed?
A PNF stretch consists of a passive stretch followed by an isometric muscle contraction. A partner passively moves a body part to its ROM limit, and then the client isometrically contracts the muscle being stretched for 10‒15 seconds before relaxing the muscle briefly. The partner then passively moves the body part to a new ROM.
What is tendon avulsion?
An avulsion fracture occurs when a small chunk of bone attached to a tendon or ligament gets pulled away from the main part of the bone.
Where do tendon avulsions most commonly occur in young athletes?
The hip, elbow and ankle are the most common locations for avulsion fractures in the young athlete.
