ch 7-10 Flashcards
what are the health related fitness components?
- aerobic capacity
- anaerobic capacity
- body composition
- muscular strength
- muscular endurance
- flexibility
what are the skill related fitness components?
- balance
- reaction time
- coordination
- agility
- speed
- muscular power
what is aerobic capacity and what the factors affecting it?
it is the ability of the heart, blood vessels and respiratory system to supply o2 to the muscles and for the muscles to use this o2 for sustained activity.
it is affected by - an efficient and strong heart
- lung adaptions
- muscle
- blood vessels
what is anaerobic capacity and what the factors affecting it?
this is how quickly work is done by anaerobic energy systems.
it is affected by the amount of fuel stores and the ability of the individual to tolerate lactic acid.
what is muscular strength and what are the factors affecting it?
muscular strength is the maximal force that can be generated by a muscle group in one effort
eg max bench press
this is affected by - age
- gender
- muscle cross sectional area
- fibre type
name an explain the two types of muscle contractions
isotomic
concentric- muscle produces tension while shortening
eccentric- muscle produces tension while lengthening
isometric- muscle length remains constant as force is developed.
what is muscular endurance and what are the factors affecting it?
this is the ability of the muscle to perform repeated contractions for extended periods.
this is affected by
- fibre type
- age
- gender
what is flexibility and what are the factors affecting it?
this is the capacity of a joint to work through a full range of motion.
this is affected by
- type of joint (socket vs hinge)
- temperature (the warmer the muscle the more it stretches)
- age (younger people are more flexible)
- gender (females are more flexible)
what is the difference between health and skill related components?
skill related components refer to improved performance rather than fitness.
what is coordination?
the ability to use the bodies senses to execute motor skills smoothly and accurately.
what is balance?
maintaining equilibrium in the body while stationary or moving
what is reaction time?
the from presentation of stimulus to the onset of a response.
describe agility
agility is the ability to change direction quickly, coupled with the ability to react to stimulus and respond quickly.
what is speed and what are the factors affecting it?
How fast your body parts(eg boxing) or your whole body can move from one point to another.
it is affected by
- fibre type
- rate of force production
- elasticity of muscles
- ATP production
what is muscular power and what are the factors affecting it?
-the ability of muscles to exert force rapidly
it is affected by
- fibre type
- balance
- speed of movement (if done too fast it affects force production)
