Chp.7 Flexibility Training Concepts

Question 1

Flexibility definition?

Answer 1

• ability to move JOINT through its COMPLETE RANGE OF MOTION.

Question 2

“Dynamic range of motion” definition?

Answer 2

• flexibility + NS ability to control this range of motion

Question 3

What are muscle imbalances?

Answer 3

• where some muscles are overactive (compensation for other underactive muscles)

Question 4

Give an example of relative flexibility?

Answer 4

• (tendency of body to seek path of least resistance)

e. g. people who squat with feet externally rotated.

Question 5

“Simultaneous relaxation of one muscle and the contraction of its antagonist.” e.g. when biceps contracts, triceps relaxes

Answer 5

• RECIPROCAL INHIBITION (there is also, altered reciprocal inhibition where a tight agonist muscle decreases neural drive of antagonist)

Question 6

Main principle in flexibility training?

Answer 6

• AUTOGENIC INHIBITION -

- > prolonged stimulation of the Golgi tendon overrides signal of muscle spindle and causes muscle to relax.

Question 7

“consistently repeating the same pattern of motion, which may place abnormal stresses on the body.”

Answer 7

• PATTERN OVERLOAD.

Question 8

Describe the cumulative injury cycle!

Answer 8

• damage to tissue causes INFLAMMATION, which causes muscle tension and muscle SPASM. The spasms cause adhesions (KNOTS) to start to form in the soft tissue. Left untreated, these begin to form permanent structural changes.

Question 9

Davis’s Law?

Answer 9

• soft tissues model along the lines of stress.

Question 10

Why is an integrated fitness assessment and a flexibility training program important?

Answer 10

• if you jump straight into cardio or strength, this might cause additional STRESS to muscles and joints if they already have improper mechanics and faulty recruitment patterns.

Question 11

manipulative treatment that attempts to release tension in the fascia due to trauma, posture, or inflammation.

Answer 11

• self-myofascial release

Question 12

“connective tissues that surround muscles, bones, nerves, and organs of the body”

Answer 12

• fascia

Question 13

Active-isolated stretch vs. dynamic stretching?

Answer 13

• active-isolated = uses agonists and synergists to move joint (specific muscles)
• dynamic = uses muscle force and MOMENTUM (more intense; stretches multiple muscles)

Question 14

“High muscular tension?”

Answer 14

• hypertonicity
