DEFINITIONS Flashcards
Ability
inherited, stable traits that determine an individual’s potential to learn or acquire a skill.
Adaptability
The potential to change with ease
Define adrenaline
natural hormone released to speed heart rate up
aerobic
with oxygen. when exercise is not too fast and is steady, the heart rate can supply all the oxygen that the working muscles need.
glucose + oxygen —> energy + carbon dioxide + water
aerobic training zone
the aerobic training zone allows the aerobic system to be trained.
60-80 percent of maximum heart rate.
define aggression.
a deliberate intent to harm or injure another person, which can be physical or mental (direct or indirect).
agility
the ability to move and change direction quickly (at speed) whilst maintaining control.
agonist/prime mover
muscle or group responsible for the movement
altitude
a geographical area of land which is over 2000m above sea level.
altitude training
training at altitude is where there is less oxygen. The body adapts by making more red blood cells to carry oxygen. The additional oxygen carrying red blood cells is an advantage for endurance athletes returning to see level to compete.
altitude sickness
nausea caused by training at altitude.
alveoli
air sacs in lungs
amateur
takes part in activity as a hobby, rather than for financial gain
has another main job outside of sport
takes part for fun
could be at a lower level.
anabolic steroids
artificially produced male hormones mimicking testosterone. The promote muscle and bone growth, and reduce recovery time. Often used by power athletes, eg sprinters.
anaerobic
without oxygen. when exercise duration is short and at high intensity, the heart and lungs cannot supply blood and oxygen to muscles as fast as the respiring cells need them.
glucose —> energy + lactic acid.
antagonist
acts to produce the opposite action to the agonist. they work in antagonistic pairs.
arousal
a physical and mental state of alertness/readiness, varying from deep sleep to intense excitement/alertness.
articulating bones
where two or bones meet to allow movement at a joint.
axis
imaginary line through the body at which it rotates.
longitudinal - head to toe.
transverse - through the hips.
sagittal - through the belly button.
backflow
the flowing backwards of blood. Valves in the veins prevent this from happening.
balance
the maintenance of the centre of mass over the base of support. Reference can be made whilst static (still) or dynamic (moving).
balanced diet
eating:
- the right amount (for energy expended)
- the right amount of calories
- according to how much you exercise
- different food types to provide suitable nutrients, vitamins and minerals.
