Angular motion Rotation around an axis (usually the bodies center line or a joint)

Atrophy Decrease in Muscle size

Biomechanics Our bodies mechanical system of muscles and bones which work in conjunction as levers to apply force to create linear motion or angular motion to overcome gravity's force.

Closed chain sports Where a skill or sport is performed in an environment that allows an individual to make decisions and perform with out the interference from opponents .eg. Kata competition, pistol shooting, gymnastics

Compound Multi-joint movement

Concentric contraction Applying Force as the muscle shortens.
(Where a muscle applies force to lift an external load resisting the force of gravity)

Cycle / phase A period of time (usually weeks or months ) where an individual focuses on a certain component of their training

Depression

Downward rotation

Dynamic Movement .eg. Dynamic posture is the ability to maintain posture during movement

Eccentric contraction Applying Force as the muscle lengthens.
(Where muscles apply force to lower an external load in the direction of gravity)

Elevation

Extension Applying a push force at a joint (Where two bones attached to opposite sides of a joint move apart)

Flexion Applying a pull force at a joint (Where two bones attached to opposite sides of a joint move to towards each other)

Functional movement Movement that your body is designed to do with minimal effort, that places minimal stress on the body's joints

Hypertrophy Increase in Muscle size

Inferior Vertical Pull Upright row

Inferior Vertical Push Dips

Isolation Single-joint movement

Isometric contraction Where muscles apply force to bones with no movement. eg. Trying to push over a brick wall

Linear motion Movement in a straight line

Open chained sports Where a skill or sport is performed in an environment that is constantly changing, this in turn puts pressure on an individual to perform and make decisions eg. basket ball, boxing, hockey tennis etc

Periodization The planning and the timing of all the individual components that an athlete needs to help them excel in their chosen sport

Phase / cycle A period of time ( usually weeks or months ) where an individual focuses on a certain component of their training

Plyometrics Before a muscle starts a powerful concentric contraction it is stretch out by either gravity in the form of an eccentric contraction or by the opposing muscle groups. This stretching (known as a "pre stretch") gives the additional benefit of a sling shot effect, which adds to the total power out-put

Pre stretch (See plyometrics )

Prone When the human body is horizontal face down

Protraction

Retraction

RM Repetition Maximum: The maximal weight that an individual can lift over a given number of repetitions. Eg A 7-RM is the maximal weight that an individual can lift over 7 repetitions

Scapulohumeral rythm The relationship between the scapula and the humerus during movement

Shearing Force Force perpendicular to a joint that tends to pull joints apart

SSC Stretch shortening cycle (see plyometrics)

Static No movement .eg. Static posture is the ability to maintain posture in a stationary position

Supine When the human body is horizontal face up

Superior Vertical Pull Lat pulldown / chin ups

Superior Vertical Push Shoulder Press

Upward rotation

Velocity Speed of movement
