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

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

Guidance

Given to aid the learning of a skill:

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

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.

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)
