Ch 9 - Core

Question 1

Core

Answer 1

lumbo-pelvic-hip complex, including lumbar spine, pelvic girdle, and hip joint; all muscles that attach to pelvis, spine, and hips

Question 2

Local core stabilizers

Answer 2

muscles that attach to the vertebrae; protect vertebrae and provide stability to segments of the spine; responsible for inter-vertebral stability; Type 1 muscles with high density of muscle spindles

Question 3

Local core stabilizing muscles (5)

Answer 3

TA, internal obliques, multifidus, pelvic floor, diaphragm

Question 4

Global core stabilizers

Answer 4

muscles that attach pelvis to spine; transfer load between upper and lower extremities; provide stabilization during functional movement

Question 5

Global core stabilizing muscles (7)

Answer 5

QL, psoas major, external obliques, some internal obliques, RA, glute medius, adductors (5)

Question 6

Movement system

Answer 6

muscle that attach spine or pelvis to extremities; create force during dynamic activities

Question 7

Movement system muscles (4)

Answer 7

lats, hip flexors, quadriceps, hamstrings

Question 8

Drawing in

Answer 8

recruiting local stabilizers by drawing navel toward spine while keeping neutral spine and not protruding head

Question 9

Bracing/Bearing down

Answer 9

activating global stabilizers by co-contracting abdominal, lower back, and glute muscles

Question 10

Core stabilization exercises

Answer 10

primarily isometric contraction exercises with little movement, focus on bracing and drawing in; improve NM efficiency and inter-vertebral stability

Question 11

Core strength exercises

Answer 11

dynamic eccentric and concentric spine movements in full ROM at medium tempos; improve dynamic stabilization, eccentric and concentric force, and NM efficiency of kinetic chain

Question 12

Core power exercises

Answer 12

improve rate of force production of core musculature; prepare to dynamically stabilize and generate force at functional speeds; explosive movements
