What is health
A state of complete physical, mental and social wellbeing and not merely the absence of disease and infirmity
What is fitness
The ability to meet, or to cope with, the demands of the environmetn
What are the components of fitness
- agility
- balance
- cardiovascular endurance
- coordination
- flexibility
- muscular endurance
- power
- reaction time
- strength
- speed
What is agility
The ability to move and change direction quickly, at speed, while maintaining control
What is balance
The ability to keep the body stable by maintaining the centre of the mass over the base of support
What are the two types of balance
- static balance, little to no movement
- dynamic balance, when movement takes place
Example of a static balance
Handstand
Example of a dynamic balance
Cartwheel
What is cardiovascular endurance
Often referred to as aerobic power.
Ability of the heart to supply oxygen to the working muscles
What is coordination
The ability to use two or more different parts of the body together, smoothly and efficiently
What is flexibility
The range of movement possible at a joint
What is muscular endurance
Ability of a muscle or muscle group to undergo repeated contractions, avoiding fatigue
What is fatigue
- feeling of extreme or severe tiredness due to a build-up of lactic acid in the muscles
- working for long periods of time
What is power
Product of strength and speed
Power formula
Power = strength x speed
What is reaction time
The time taken to start responding to a stimulus and the performer starting to respond
What is strength
The ability to overcome resistance
What are the 4 types of strength
- maximal strength
- static strength
- explosive strength
- dynamic strength
What is maximal strength
The greatest force that is possible in a single muscle contraction
What is static strength
The amount of force exerted on an object you cannot move
What is explosive strength
The amount of force exerted in one quick muscle contraction
What is dynamic strength
The amount of force exerted repeatedly by a muscle
What is speed
The maximum rate at which an individual is able to perform a movement or cover a distance in a period of time, putting their body parts into action as quickly as possible
How to calculate speed
Speed = distance/time
