Components Of Fitness Flashcards
Localised Muscular Endurance
The ability of a muscle o a group of muscles to sustain repeated contractions against a resistance for an extended period of time.
e.g. Movement of the legs during long distance cycling.
Strength
The force that can be developed in a muscle or a group of muscle during a contraction.
e.g. Weight-lifting.
Maximal Strength
The maximum force that can be developed in a muscle or a group of muscles during a single maximal contraction.
e.g. 1 rep max - Power lifting, Weight lifting.
Power
The rate at which force is produced.
e.g. the legs during a long jump take-off.
Speed
The time taken for a body (part or whole) to move through a movement over a predetermined distance.
Speed = Distance / Time
e.g. 100m sprint.
Agility
Changing body position quickly and with control without losing balance, in response to a stimulus.
e.g. A rugby player dodging a tackle.
Coordination
The ability of the body to link movements together, either with other movements, or in relation to an external object.
e.g. A tennis player responding to a serve and hitting the ball.
Reaction Time
The time taken for a performer to respond to a stimulus, and the initiation of their response.
e.g. An 100m sprinter responding to the start gun and pushing off of the blocks.
Balance (Static + Dynamic)
The ability to maintain your centre of mass over a base of support.
e.g. Static: Handstand.
Dynamic: Beam skills (jumps).
Flexibility
The range of movement available at a joint.
e.g. Gymnast doing the splits.
Exercise Economy
The energy required to maintain a constant velocity of movement.
e.g. Long distance running (Marathon).
VO2 Max
The maximum volume of oxygen (ml) that can be utilised in 1 minute.
Higher VO2 = better physical fitness.
e.g. untrained vs trained elite athlete.
Submaximal Aerobic Fitness
The ability to maintain a high percentage of VO2 max for a prolonged period of time.
Anaerobic Capacity
The amount of energy obtained from anaerobic sources in a single bout of exercise.
ATP
Adenosine Triphosphate:
When working at high intensities, not enough oxygen is supplied for aerobic respiration:
ATP is broken down to release energy for tissues to use for movement.
Better anaerobic capacity = better ability to release ATP = better high-intensity performance.
