definition: the ability of the cardiorespiratory system to
work efficiently, supplying nutrients and oxygen to working
muscles during sustained physical activity.
Can enhance performance in aerobic and muscular training
Reduces risk of injuries
Reduces stress and tension in muscles
Speed
definition: distance divided by the time taken. Speed is
measured in metres per second (m/s). The faster an
athlete runs over a given distance, the greater their
speed
Depends on acceleration
One of the main fitness components
Important for success in many sports
Requires good strength and power
Very important as part of overall fitness
Muscular Strength
definition: the maximum
force (in kg or N) that can be
generated by a muscle or
muscle group.
Improves athletic performance
Increase in stamina
Increase in bone density
Decreases the effects of aging
Aerobic Endurance
definition: the ability of the
cardiorespiratory system to
work efficiently, supplying
nutrients and oxygen to
working muscles during
sustained physical activity.
Short aerobic
2-8 mins of aerobic/lactic training
Medium Aerobic
8-30 mins of mainly aerobic training
Long Aerobic
30+ mins of aerobic training
Body Composition
definition: the relative ratio of fat mass to fat-free mass
(vital organs, muscle, bone) in the body.
Body fat is located within the body
Stored in muscle tissues, under skin and around organs
Some body fat neccessary for healthy life
Protects organs and provides energy
Fat-free mass includes bone, water, muscle and tissues
Ensures the body functions properly
Muscular Endurance
definition: the ability of the muscular
system to work efficiently, where a muscle
can continue contracting over a period of
time against a light to moderate fixed
resistance load.
eg: how many times you can do a bicep curl
without breaking your technique
The push-up test can be a good measure of
muscular endurance
How many you can do without breaking form or in
a certain time frame(eg: 1 minute)
