Chapter 14 Flashcards
What are the recommended training variables for dynamic stretching?
1 set, 10 to 15 repetitions, 3 to 10 exercises
Which principle states that soft tissue will model along the lines of stress?
Davis’s law
What are the two primary actions of the Golgi tendon organ?
Sense change in muscle-tendon tension and speed of tension change
What is the neuromuscular phenomenon that occurs when a synergist muscle takes over for a weak or inhibited muscle?
Synergistic dominance
Which term best describes observable movement of the limbs?
Osteokinematics
What is pertinent information for the fitness professional to consider before prescribing flexibility exercises?
Any medical precautions or contraindications
Which statement best describes the neurophysiological effect that occurs from myofascial rolling?
The direct roller compression may create tissue relaxation and pain reduction in tissues by stimulating nerve receptors.
When performing a dumbbell biceps curl, the biceps brachii is considered the agonist (prime mover), and the triceps become the inhibited antagonist. What is this phenomenon called?
Reciprocal inhibition
Why is the hurdler’s stretch considered to be a controversial lower-body stretch?
The stretch provides excessive stress to the inside of the knee.
The hamstring complex compensating for weakened hip extensors, which cannot produce force effectively, is an example of what key term?
Synergistic dominance
If a muscle is stretched too quickly, the muscle responds with an immediate contraction to stop the stretch. What is this specific action called?
Stretch reflex
What are two contraindications for self-myofascial techniques?
Cancer and bleeding disorders
Why is the shoulder stand yoga pose considered to be a controversial upper-body stretch?
This stretch provides excessive stress to the neck, shoulders, and spine.
What concern should you have when prescribing flexibility exercises to a client with osteoporosis?
Osteoporosis is considered a contraindication to myofascial rolling.
What is the process in which neural impulses that sense tension are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles?
Autogenic inhibition
Which type of nerve receptor senses pain?
Nociceptor
Flexibility is defined as the following:
Normal extensibility of all soft tissues that allows for complete range of motion
Which lower-body stretch is considered controversial and may be a risk for injury?
Inverted hurdler’s stretch for hamstrings
Which lower-body stretch is considered controversial and may be a risk for injury?
Inverted hurdler’s stretch for hamstrings
What is considered to be the mechanism of action with self-myofascial rolling?
Autogenic inhibition
The lengthening reaction is often seen with what type of flexibility technique?
Static stretching
