Abduction
Movement away from the midline of the body
Adduction
Movement towards the midline of the body
Aerobic exercise
Use of oxygen for the duration of the exercise. Usually at moderate intensity at a continuous rate eg; long distance running
Agility
The ability to change direction at speed; nimbleness
Agonist
The muscle that works to create the movement
Antagonistic muscle action
A pair of muscles that work together to produce movement with one muscle contracting whilst the other muscle relaxes. Eg the upper arm flexes the bicep contracts and the triceps relaxes
Anaerobic exercise
Exercise which does not allow for the predominant usage of oxygen. Usually high or very high intensity for a short period of time. Eg; sprinting up a hill
