Ability
Inherited, stable traits that determine an individual’s potential to learn or acquire a skill.
Adaptability
The potential to change with ease.
Adapted sports
Competitive sports for individuals with disabilities.
Adduction
Movement where limbs are moved towards the midline of the body.
Adrenaline
Natural hormone released to speed heart rate up.
Aerobic
With oxygen. When exercise is not too fast and is steady, the heart can supply all the oxygen that the working muscles need.
Summarised as: glucose + oxygen → energy + carbon dioxide + water.
Aerobic training zone
The aerobic training zone allows the aerobic system to be trained. To define aerobic training: 1. Calculate maximum heart rate (220 bpm) minus age: 220-age 2. Work at 60-80% of maximum heart rate.
Aggression
A deliberate intent to harm or injure another person, which can be physical or mental.
Agility
The ability to move and change direction quickly at speed, while maintaining control.
Agonist (prime mover)
Muscle or group responsible for the movement.
Altitude
A geographical area (of land) which is over 2,000 m above sea level.
Altitude training
Training at altitude 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 sea level to compete.
Altitude sickness
Nausea caused by training at altitude.
Alveoli
Air sacs in the lungs.
Amateur
This term defines someone who takes part in an 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. They 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.
Summarised as: glucose → energy + lactic acid.
Arousal
A physical and mental (physiological and psychological) state of alertness/readiness, varying from deep sleep to intense excitement/alertness.
Arteries
Blood vessels carrying blood away from the heart.
Articulating bones
Where two or more bones meet to allow movement at a joint.
Atria
Upper chambers of the heart that collect blood from the veins.
Axis
Imaginary line through the body around which it rotates. Types of axis: longitudinal (or vertical) – 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 to whilst static (still) or dynamic (whilst moving).
