AOS1U4 FC Flashcards
Aerobic Power
The maximum rate of energy production from the aerobic energy system. (energy produced in the presence of oxygen).
Factors that affect aerobic power
Cardiac Output
Age
Body Composition
is defined as the percentage of fat, muscle, and bone in the body.
Factors that influence Body Composition
Age % body fat will decrease as hormone production slows down
Gender males have lower fat
muscular strength
The maximum amount of force that a muscle can exert against some form of resistance in a single effort.
Factors that influences Muscular Strength
muscle type
fast twitch fibres
muscular endurance
the ability of a muscle or muscle group to do repeated contractions against a less-than-maximum resistance for an extended period of time.
Factors that influence muscular endurance
Capacity to delay onset of fatigue
muscle fibre type
flexibility
defined as the ability to move joints or muscles through their full range of motion.
Factors that influence flexibility
muscle temp increase elasticity
gender females more flexible
anaerobic capacity
The total amount of energy obtainable from the anaerobic energy system.
Factors affecting Anaerobic capacity
gender males - fast twitch fibres
lactate tolerance
muscular power
Muscular power is the ability to contract muscles with speed and force in one explosive act.
power = force x velocity
Factors affecting power
Number and size of motor units recruited
Frequency of motor unit stimulation
speed
a measure of the ability to move all or part of the body as quickly as possible.
