The ability to change direction quickly at speed; nimbleness

Agonist

The muscle that works to create the movement

Antagonist

The muscle that works in the opposite way to the agonist

Antagonistic muscle action

A pair of muscles that work together to produce movement with one muscle contracting whilst the other muscle relaxes.

Anaerobic exercise

Exercise which does not allow for the predominant usage of oxygen. Usually high or very high intensity for a short period of time.

Axes of Rotation

A line around which the body can turn

Balance

The ability to stay upright or stay in control of body movement

balanced diet

A diet that contains the correct proportions of carbohydrates, fats, proteins, vitamins, minerals and water necessary to maintain good health

Beta Blockers

A drug used to control heart rhythm and lower blood pressure

Breathing rate

the number of breaths taken in a minute

Capillarisation

The development of blood capillaries in the body which increases through long term effects of exercise

cardiac output

The volume of blood on,led per minute by each ventricle of the heart.

Cardiac output= stroke volume x heart rate

Circuit training

Series of alternate exercises performed at stations that focus on different muscle groups

Circumduction

The circular movement of a joint. It is a movement pattern that combines flexion, extension, adduction, abduction and rotation.

closed skill

A skill performed in a predictable environment

Complex skill

A skill which requires a lot of focus and decision making to perform

confidence

The degree to which a performer believes they have the ability to perform and complete tasks with success

Continuous training

Training that involves activity without rest intervals. It can be performed at any intensity

cool down

The act of allowing physiological activity to return to normal gradually after strenuous exercise be engaging in less strenuous exercise. Aims to slowly decrease breathing, heart rate and muscle temperature.

Coronary Heart Disease (CHD)

Where the blood vessels are narrowed and blood flow and oxygen to the heart is reduced

Discrimination

The unfair treatment of individuals whereby opportunities are not available to all of the different social groups.

Double circulatory system

The human body has two circulatory loops in which blood circulates. One is oxygenated, and the other is deoxygenated.

Systemic - the circulatory loop that controls blood flow from the heart to the rest of the working muscles and organs.

Pulmonary - the circulatory loop that controls blood flow from the heart to the lungs

extension

A straightening movement around a joint

fatigue

Muscle tiredness when the body has a lack of energy

FIIT

FIIT outlines the key components of an effective exercise program:

Frequency - the number of times exercise takes place

Intensity - how hard and intense the exercise it

Time - how long you exercise for

Type - the kind of exercise that takes place

Flexibility

Range of movement available around a joint

Flexion

A bending movement around a joint in a limb

frontal plane

An imaginary line that divides the body from the front to the back vertically

Gamesmanship

Where the laws of the game are interpreted in ways, which whilst not illegal, are not in the spirit of the game. Pushing the limits to gain unfair advantage.

gas exchange

The movement of gases taking place at the alveoli and capillaries

gender

The state of being male or female

Golden Triangle

The links and relationship between sponsorship, sporting events and the media

Guidance

Given to aid the learning of a skill:

Visual- use of demonstrations that allow the performer to 'see' the skill

Verbal- the coach will explain the technique

Manual- the coach will physically manipulate the athlete through the skill

Mechanical- use of apparatus or aids that assist the performer

Heart Rate

number of heart beats per minute

Hydration

Having the appropriate level of water in the body for it to function optimally. When this level of water falls below optimal levels it is referred to as dehydration.

Interval training

Training that incorporates periods of exercise and rest

Lactic Acid

A waste product produced in the muscle tissues during strenuous exercise where the anaerobic energy system is in use.

Levers

1st Class - A lever in which the fulcrum is positioned between the load and the effort (EFL)

2nd Class - A lever which has the load and the effort on the same side of the fulcrum, with the load nearer the fulcrum (ELF)

3rd Class - The effort is placed between the load and the fulcrum, and the effort must travel a shorter distance and e greater than the load (FEL)

Ligament

a short band of tough and flexible tissue that connecting bones together and stabilise the joint.

Longitudinal axis of rotation

Passes vertically from the top to the bottom of your body. A 360 degree turn rotates through this axis.

mechanical advantage

1st and 2nd class levers provide mechanical advantage, this means that a larger load can be moved with a smaller amount of effort.
