NASM Chapter 10: Dynamic Balance Concepts

_____ is the ability of the body to move and change directions under various conditions without falling.

• Scapular retraction

• Active Flexibility

• Dynamic Balance

• Autogenic Inhibition

Identify a neuromuscular skill that strongly influences the dynamic balance of a person.

• Pressure

• Force

• Control

• Endurance

The ability to reduce force at the right joint, at the right time, and in the right plane of motion requires optimal levels of dynamic balance and _____.

• autogenic inhibition

• synergistic dominance

• controlled instability

• neuromuscular efficiency

Balance is defined as:

• the ability of the body to use two or more body parts together.

• the state in which the body is in equilibrium and is stationary.

• the state in which the body is in linear or angular movement.

• the ability of the body to move and change directions.

Which of the following is true of balance?

• It is attained by increasing force and stabilization.

• It is dependent only on external factors.

• It is both a static and a dynamic process.

• It is based on center of gravity rather than support.

Balance is dependent on _____ to maintain the body’s center of gravity.

• both physiological and psychological factors

• biological factors

• environmental factors

• both internal and external factors

Maintenance of _____ is an integrated process requiring optimal muscular balance, joint dynamics, and neuromuscular efficiency using visual, vestibular, and proprioceptive inputs.

• postural equilibrium

• dynamic equilibrium

• static equilibrium

• mechanical equilibrium

In the context of balance training, alterations in the kinetic chain before, during, or after exercise can lead to _____.

• an increase in force production

• flawed movement patterns

• postural equilibrium

• an increase in motor unit synchronization

What happens as a result of flawed movement patterns during balance training?

• The structural integrity of the kinetic chain remains unchanged.

• Neuromuscular efficiency is increased.

• Synergists and stabilizers become less active.

• The firing order of the muscles activated is altered.

Joint dysfunction leads to joint injury, swelling, and interruption of sensory input from articular, ligamentous, and muscular mechanoreceptors to the central nervous system, resulting in _____.

• postural equilibrium

• disturbance in proprioception

• increased rate of force production

• increased motor unit synchronization
