Name the 6 Health related fitness components
Aerobic Capacity Anaerobic Capacity Muscular Strength Muscular Endurance Flexibility Body Composition
Define Aerobic Capacity
The total amount of energy obtainable from the aerobic energy system.
Define anaerobic capacity
Total amount of energy obtainable from the anaerobic energy systems.
Define anaerobic power
How quickly energy can be produced by the anaerobic energy systems.
Define muscular strength
Muscles ability to generate force against an object
Define muscular endurance
Ability of a muscle or group of muscles to perform repeated contractions against a resistance for an extended period of time whilst fatiguing.
Define flexibility
The capacity for a joint to move through its range of motion
Define body composition
The make up whole body including fat and fat free mass (Teeth, bones, water, fat, muscle ect.)
Define muscular power
The ability of a muscle or muscle group to exert a maximum amount of force in the shortest period of time.
Define Speed
The rate of motion
Whole body or body part
Define agility
A rapid whole body movement with change in direction in repose to stimuli.
Define Co-ordination
Ability to use the bodies senses to execute motor skill accurately
Define balance
Maintaining equilibrium while stationary or moving
Define Reaction time
The time taken from the presentation of the stimulus to the onset of a response.
Factors affecting Aerobic endurance
Stroke volume
Blood vessels
Healthy respiratory system
Haemoglobin levels
Factors affecting anaerobic power
% fast twitch fibre
Factors affecting muscular power
Force generated. (Muscle size)
Speed of muscle contraction (% fast twitch fibre)
Factors affecting speed
Efficiency of anaerobic system Muscle activation (motor units) Rate of force production (linked to Muscular power) % fast twitch fibre Stiffness of connective tissue
Factors affecting strength
Length of muscle fibre Angle of joint during contraction Optimal myosin-actin overlap Speed of contraction Muscle size Fibre arrangement Muscle Fibre type
Factors affecting local muscular endurance
