Chapter 17 - Balance Training Concepts

Question 1

Balance

Answer 1

the ability to maintain one’s center of gravity within that person’s base of support

Question 2

Center of gravity

Answer 2

the approximate midpoint of the body; midportion of the trunk

Question 3

Base of support

Answer 3

the area beneath a person that consists of every point of contact made between the body and the support surface

Question 4

Limits of stability

Answer 4

the area within which an individual can move one’s center of gravity without changing the base of support without falling

Question 5

Static balance

Answer 5

the ability to maintain the center of mass within the base of support in a stationary position, meaning no linear or angular movement

Question 6

Semi-dynamic balance

Answer 6

the ability to maintain the center of mass with a stationary base of support yet allowing movement for the base supporting the body (riding skateboard)

Question 7

Dynamic balance

Answer 7

the ability to maintain a center of mass over an ever-changing base of support (running on uneven surfaces)

Question 8

Vestibular system

Answer 8

provides information about the position of the body and head

Question 9

Somatosensory system

Answer 9

provides information that is acquired from receptors in the body about the position and motion of the body parts relative to other body regions and the support surface

Question 10

Sensorimotor function

Answer 10

interaction between the way the body processes visual, vestibular, and somatosensory information with the motor response of the body to that information

Question 11

Perturbation

Answer 11

an alteration of the body’s current state caused by the application of an external force

Question 12

Proprioceptively enriched environment

Answer 12

an unstable (yet controlled) exercise environment that causes the body to use its internal balance and stabilization mechanisms
