Volcab Ch 5 Flashcards
Abduction
A movement in the frontal plane away from the midline of the body.
Acceleration
When a muscle exerts more force than is being placed on it, the muscle will shorten; also known as a concentric contraction or force production.
Adduction
Movement in the frontal plane back toward the midline of the body.
Advanced Stage
The second stage of the dynamic pattern perspective theory when learners gain the ability to alter and manipulate the movements more efficiently to adapt to environmental changes.
Anatomic Locations
Refers to terms that describe locations on the body.
Anatomic Position
The position with the body erect with the arms at the sides and the palms forward. The anatomic position is of importance in anatomy because it is the position of reference for anatomic nomenclature. Anatomic terms such as anterior and posterior, medial and lateral, and abduction and adduction apply to the body when it is in the anatomic position.
Anterior (or Ventral)
On the front of the body.
Association Stage
Fitt?s second stage in which learners become more consistent with their movement with practice.
Augmented Feedback
Information provided by some external source such as a fitness professional, videotape, or a heart rate monitor.
Autonomous Stage
Fitt?s third stage of motor learning in which the learner has refined the skill to a level of automation.
Biomechanics
- A study that uses principles of physics to quantitatively study how forces interact within a living body. 2. The science concerned with the internal and external forces acting on the human body and the effects produced by these forces.
Chain
A system that is linked together or connected.
Cognitive Stage
Fitt?s first stage of motor learning that describes how the learner spends much of the time thinking about what they are about to perform.
Concentric Muscle Action
When a muscle is exerting force greater than the resistive force, resulting in shortening of the muscle.
Contralateral
Positioned on the opposite side of the body.
Decelerate
When the muscle is exerting less force than is being placed on it, the muscle lengthens; also known as an eccentric muscle action or force reduction.
Distal
Positioned farthest from the center of the body, or point of reference.
Dorsal
Refers to a position on the back or toward the back of the body.
Dorsiflexion
When applied to the ankle, the ability to bend at the ankle, moving the front of the foot upward.
Dynamic Functional Flexibility
Multiplanar soft tissue extensibility with optimal neuromuscular efficiency throughout the full range of motion.
Dynamic Joint Stabilization
The ability of the stabilizing muscles of a joint to produce optimum stabilization during functional, multiplanar movements.
Dynamic Pattern Perspective (DPP)
The theory that suggests that movement patterns are produced as a result of the combined interactions among many systems (nervous, muscular, skeletal, mechanical, environmental, past experiences, and so forth).
Dynamic Stabilization
When a muscle is exerting force equal to the force being placed on it. Also known as an isometric contraction.
Eccentric Muscle Action
An eccentric muscle action occurs when a muscle develops tension while lengthening.
