First 185 words of the document:

Defining fitness: - `the ability to carry out everyday activities without
undue fatigue.' or `the ability to meet the demands of your
environment or lifestyle.'
Defining health: - `a state of physical, social and mental well being
where we are free from disease.'
Components of fitness
Cardio respiratory endurance (aerobic capacity) (stamina)
Muscular endurance
Reaction time
Body composition
Stamina or cardio respiratory endurance (aerobic capacity): - `the ability of
the cardiovascular and respiratory systems to take in and transport
oxygen to the working muscles where it can be utilized and aerobic
performance maintained.'
E.g. A triathlete requires high amounts of cardio respiratory endurance but
a weightlifter doesn't.
Factors influencing cardio respiratory endurance include: -
Efficiency of gaseous exchange at both lungs and muscle cells
Effectiveness of oxygen transport from the lungs to the muscle cells
Ability of the muscle cells to utilize oxygen that they receive

Here's a taster:

Performers with high cardio respiratory endurance may possess the
following: -
Greater capillarisation of the alveoli and muscles
Greater concentration of red blood cells, and therefore haemoglobin,
in the blood, which helps transport the oxygen to the working
A greater proportion of slow oxidative muscle fibers
Greater concentration of myoglobin within the muscle cell, which
helps to store the oxygen and transport it to the mitochondria.
A greater number and size of mitochondria, which can utilize the
oxygen to provide energy.…read more

E.g. sports performers requiring high levels of elastic strength include
sprinters, triple jumpers and gymnasts.
3. Strength endurance: - the ability of a muscle or group of muscles to
undergo repeated contractions and with stand fatigue.

Determining factors include: -
High number of fast twitch glycolytic muscle fibers within muscle
High stores of phosphocreatine within the muscle. (fuel used to
help muscle contraction during very high intensity activities e.g.
Highly effective lever systems, which put limbs into motion
Tests for speed include: - 30m sprint test
Flexibility: - `the range of movement possible at a joint'
E.g. gymnastics and trampolining through to football and hockey.…read more

Tests for agility include: -
Illinois agility run test
Hexagon jump test
Balance: - `The maintenance of the body's centre of mass over the
base of support.'
Static balance e.g. when a gymnast is stationary. Maintaining their centre
of mass over their base of support performing a handstand
Dynamic balance is maintenance of a balanced position while moving. E.g.…read more

Rhythm/synch ­ timing right and feeling the action e.g. strking a
moving ball
Test for coordination include: -
Alternate hand ball toss test
Light board test
Reaction time: - `the time taken to initiate a response to a given
Reaction time can be subdivided into: -
Simple reaction time ­ movement response time to a single stimulus
e.g. reacting to starters pistol in swimming
Choice reaction time ­ movement response to one stimulus or more
that requires a choice of action.…read more
