Kinesiology
|
The study of the principles of mechanics and anatomy in relation to human movement.
|
|
Motive Force
|
The force that starts or causes a movement.
|
|
Resistive Force
|
A force that resists the motion of another force.
|
|
Concentric Action
|
A contraction in which a muscle exerts force, shortens, and overcomes a resistance.
|
|
Eccentric Action
|
A contraction in which a muscle exerts force, lengthens, and is overcome by a resistance.
|
|
Isometric
|
A contraction in which a muscle exerts force but does not change in length.
|
|
Lever
|
A rigid bar that rotates aroung a fixed support (fulcrum) in response to an applied force.
|
|
Fulcrum
|
The support on which a lever rotates when moving or lifting something.
|
|
Flexion
|
Movement about a joint in which the bones on either side of the joint are brought closer to each other.
|
|
Extension
|
Movement about a joint that brings two parts into or toward a straight line, thereby increasing the angle of the joint; such as straightening the elbow.
|
|
Abduction
|
Movement of a body part away from the midline of the body.
|
|
Adduction
|
Movement of a body part toward the midline of the body.
|
|
Axis of Rotation
|
The imaginary lineor point about which an object, such as a body or a lever, rotates.
|
|
Torque
|
A force causing rotation about a fixed axis of rotation; the acto or process of turning around on an axis.
|
|
Law of Inertia
|
The tendency of all objects and matter to remain at rest, or, if moving, to continue moving in the same straight line unless acted on by an outside force; proportional to body mass.
|
|
Law of Acceleration
|
The force (F) acting on a body in a given direction is is equal to the body's mass (m) multiplied by the body's acceleration (a) in that direction: F=ma or a=F/m
|
|
Law of Impact and Reaction Forces
|
The earth exerts a force against the body that is equal to the force applied to the earth as one moves.
|
|
Kinesthetic Awareness
|
One's sense of one's position and movement in space during various activities.
|
|
Kyphosis-Lordosis
|
An increase in the normal inward curve of the low back and increased outward curve of the thoracic spine.
|
|
Flat-Back Posture
|
A position of the spine that minimizes the natural curve by placing the pelvis in a slight posterior tilt.
|
|
Sway-Back Posture
|
An exaggerated forward curvature of the lumbar spine, often resulting in a protruding abdomen and buttocks; aka Lordosis.
|
|
Scoliosis
|
A lateral curvature of the vertebral column, usually in the thoracic area.
|
|
Connective Tissue
|
The tissue that binds together and supports various structures of the body.
|
|
Agonist
|
A muscle that is directly engaged in contraction; opposes the action of an antagonist muscle.
|
|
Antagonist
|
The muscle that acts in opposition to the action produced by an agonist muscle.
|
|
Synergist
|
A muscle that assists another muscle in its function.
|
|
Co-contraction
|
The mutual coordination of antagonist muscles (such as flexors and extensors) to maintain a position.
|
|
Stabilizer
|
Muscles that stabilize one joint so a desired movement can be performed in another joint.
|
|
Isometric Action
|
A contraction in which a muscle exerts force but does not change in length.
|
|
Hyperextension
|
Extreme of excessive extension of a joint.
|
|
Superficial
|
External; located close to or on the body surface.
|
|
Aponeurosis
|
A white, flattened, tendinous expansion that mainly serves to connect a muscle to the parts that it moves.
|
|
Interdigitate
|
To interlock, like the fingers of folded hands.
|
|
Lateral
|
Anatomical term meaning away from the midline of the body; pertaining to the side.
|
|
Supine
|
The position of the body when lying face upward.
|
|
Circumduction
|
The active or passive circulat comvement of ajoint; a combination of flexion, abduction, extension and adduction mevements.
|
|
Posterior
|
Anatomical term meaning toward the back; opposite of anterior.
|
|
Medial
|
Anatomical term meaning toward the midline of the body; pertaining to the center.
|
|
Anterior
|
Anatomical term meaning toward the front. Same as ventral.
|
|
Dorsiflex
|
Movement of the dorsum (top) of the foot up toward the shin (proximally).
|
|
Eversion
|
Movement of the sole of the foot outward.
|
|
Retraction
|
Scapular adduction
|
|
Protraction

Scapular abduction.
|
|
Articulation
|
Place of union or junction between two or more bones.
|
|
Tuberosity
|
A projection or protuberance on a bone usually serving for the attachment of muscles or ligaments.
|
|
Supinate
|
A triplanar motion at the subtalar joint consisting of dorsiflexion, adduction, and inversion; looks like inversion.
|
|
Pronate
|
A triplanar motion at the subtalar joint consisting of abduction, dorsiflesion and eversion; closely resembles eversion
