NASM CES, Chapter 2
Biomechanics - Answer-A study that uses principles of physics to quantitatively study how forces
interact within a living body.
Force - Answer-An influence applied by one object to another, which results in an acceleration or
deceleration of the second object.
Rotary motion - Answer-Movement of the bones around the joints.
Torque - Answer-A force that produces rotation.
Agonist - Answer-Muscles that act as prime movers.
Antagonists - Answer-Muscles that act in direct opposition to prime movers.
Synergists - Answer-Muscles that assist prime movers during functional movement patterns.
Stabilizers - Answer-Muscles that support or stabilize the body while the prime movers and the
synergists perform the movement patterns.
Motor Behavior - Answer-The human movement system's response to internal and external
environmental stimuli.
