Metabolism |
Process in which nutrients are required, transported, used, and disposed of by the body |
|
Aerobic |
Requires oxygen |
|
Anaerobic |
Without oxygen |
|
Adenosine triphosphate ATP |
Energy storage and transfer unit within cells |
|
Anaerobic threshold |
Where the body can no longer produce enough energy with normal oxygen intake |

Excess post oxygen consumption EPOC |
Elevation of metabolism after exercise |
|
Biomechanics |
Science concerned with internal and external forces acting on the body |
|
Force |
Influence applied by one object to another, accelerates or decelerates the second object |
|
Torque |
A force that produces rotation |
|
Lever |
Rigid “bar“ that rotates around a stationary fulcrum |
|
First class lever |
Fulcrum in the middle nodding head |
|
Second class lever |
Resistance in the middle. Caffrey’s |
|
Third class |

|
Abduction |
Movement in the frontal plane toward the metal |
|
Horizontal abduction |
Transverse plane are movement from anterior to lateral i.e. chest fly |
|
Horizontal adduction |
Transverse plane our movement from lateral to anterior |
|
Internal rotation |
Rotation toward the middle of the body |
|
External rotation |
Rotation away from the middle of the body |
