balancing while moving. The ability to maintain body position and equilibrium during movement.
Activities that require oxygen over a prolonged period of time. Rhythmic, steady exercise which uses oxygen to oxidise glucose, fats, and proteins to release energy for the working muscles.
Progressive Resistance Exercise (PRE)
The resistance used in training is progressively increased systematically as the body adapts to the training stimulus.
Fine Motor Skills
Involve movements using small groups of muscles in delicate actions, eg. wrist action in table tennis.
Isometric Muscle Action
Occurs when a muscle starts to contract and shorten, but is then stopped by an immovable resistance, eg. trying to lift a weight that is too heavy for you to move.
Isotonic Muscle Action
Normal muscle action, when the muscle shortens as it produces movement, eg. a biceps curl.
Training with alternating work intervals and rest intervals, eg. 6 x 200m with 60 seconds rest between each 200m run.
An acid produced by muscles working powerfully without enough oxygen (anaerobically). The increased acidity stimulates faster breathing, and causes muscle pain.
A structure with a pivot point about which an effort moves a load. There are three types of lever according to the different positions of the effort, load, and pivot.
