Chapter 14- Flexibility Training Concepts

Pattern Overload

Consistently repeating the same pattern of motion, which may place abnormal stresses on the body

a flexibility technique that focuses on the neural system and fascial system in the body

Foam rolling

What is the minimum duration for which a static stretch should be held?

30 secs

What term refers to the neuromuscular phenomenon that occurs when synergists take over function for a weak or inhibited prime mover (agonist)?

Synergistic dominance

What are the two primary actions of the Golgi tendon organ?

The Golgi tendon organ (GTO) is sensitive to changes in muscular tension and rate of tension change.

Neuromuscular efficiency

The ability of the neuromuscular system to enable all muscles to efficiently work together in all planes of motion.

Altered reciprocal inhibition

The concept of muscle inhibition, caused by a tight agonist, which inhibits its functional antagonist.

autogenic inhibition

The process by which neural impulses that sense tension are greater than the impulses that cause muscles to contract, providing an inhibitory effect to the muscle spindles.

Nociceptors

pain receptors

Contraindications

specific signs or circumstances under which it is not appropriate and may be harmful to administer a drug to a patient

Stretch tolerance

the ability of an athlete to tolerate the discomfort of stretching

Flexibility

the ability to move a body part through a full range of motion

mobility

the quality or state of being able to move about freely

lengthening reaction

When a muscle is lengthened, a cascade of neurological reactions occur that allows the muscle to be stretched.

static stretching

a technique in which a muscle is slowly and gently stretched and then held in the stretched position

Active and dynamic stretching utilize which physiological action?

Reciprocal inhibition

What is the mechanism of action for active stretching?

Reciprocal inhibition

What should precede dynamic stretching if an individual possesses muscle imbalances?

Self-myofascial techniques and static stretching

Davis's law

States that soft tissue models along the line of stress.

The lengthening reaction is often seen with what type of flexibility technique?

Static

Relative Flexibility

The tendency of the body to seek the path of least resistance during functional movement patterns

With regard to the cumulative injury cycle, current theory supports the idea that repetitive movements, such as long periods of poor posture, are believed to lead to which of the following?

Tissue trauma and inflammation

What is the goal of dynamic stretching?

To prepare the body for more intense activity
