Exam Flashcards
aerobic
requires oxygen
anaerobic
without oxygen
ATP
energy storage & transfer unit within cells
anaerobic threshold
where the body can no longer produce enough energy with normal oxygen intake.
EPOC
excess post oxygen consumption elevation of metabolism after exercise.
Torque
A force that produces rotation.
Lever
rigid “bar” that rotates around a stationary fulcrum.
1st class lever
fulcrum in middle
2nd class lever
resistance in middle
3rd class lever
effort in middle
relative flexibility
the tendency for the body to take the path of least resistance.
Autogenic inhibition
Neural impulses that sense tension are greater than the impulses that cause muscles to contract.
Reciprocal inhibition
simultaneous contraction of one muscle and relaxation of its antagonist’s muscle.
Pattern overload
Consistently repeating the same motion placing abnormal stress on the body
postural distortion patterns
predictable patterns of muscle imbalances
altered reciprocal inhibition
muscle inhibition caused by a tight agonist inhibiting it’s functioning antagonist.
synergistic dominance
inappropriate muscle takes over the function of a weak or inhibited mover.
muscle imbalance
the alteration of muscle length surrounding a joint.
sagittal planes
divides the body into right and left sides
frontal plane
divides the body into front and back
transverse
divides the body into top and bottom halves
Motor control
the study of posture and movements with the involved structures and mechanisms used by the CNS.
Internal feedback
process whereby sensory information is used by the body via length-tension relationships and force couple relationships.
external feedback
information provided by an external source, such as a personal trainer.
