The purpose of your skeleton



Your skeleton has three main

functions.



1. It supports your body



2. It protects vital organs



3. Lastly it enables movement

JOINTS

JOINTS

Joints which allow

free movement

are called Synovial

joints - they are

either hinge

joints like the

knee, or ball

and socket joints

like the hip

TENDONS

Muscles are attached

to bones by Tendons

CARTILAGE



Bones which

meet in a joint

are tipped with

Cartilage to

cushion them

and stop them

wearing away

LIGAMENTS





Bones are

held together

by strong

fibres called

Ligaments

MUSCLE FUNCTIONS

Since they can only

pull, not push, muscles

must work in pairs in

order to move limbs





Biceps

Triceps

MOVEMENT





To bend the

arm the biceps

contract, to

OXYGEN TRANSPORT SYSTEM



In order to work and create

movement, muscles need

oxygen. The body's

oxygen transport system

takes oxygen to the

working muscles, through

the circulatory and

respiratory systems

working together. The

main workers are the

heart, blood and lungs. The

whole oxygen transport

system works in a cycle.

The Respiratory System

Oxygen enters the body through the AND





Mouth Nose





The oxygen then travel to the lungs

where the oxygen enters the bloodstream







The oxygen then

travel in the which pumps the oxygen

arteries to the to the working muscles



HEART

The Respiratory System

As you exercise a waste product is

produced known as:



CARBON DIOXIDE



This is returned to your lungs by your

blood.



When you breath out the carbon

dioxide leaves your body.

The Circulatory System

The heart (a muscular pump) is at the

centre of the circulatory system. By

contracting and relaxing the heart

muscles can pump blood around the

body.



Arteries carry blood away from the

body to vital organs and limbs

(oxygenated blood)



Veins return blood to the heart

(deoxygenated blood)

The Circulatory System





De-oxygenated Oxygenated

blood from blood from

the body the lungs

enters the enters the

heart from heart from

the vena pulmonary

cava here vein here

Oxygen debt

During vigorous exercise the body needs a

lot more energy.



It gets this by breathing in deeper and

faster and rushing the oxygen to the

muscles.



This extra oxygen is then used to release

more energy, needed to meet the higher

level of demand. Soon a point is reached

when the body cannot breathe any faster or

harder, and aerobic respiration alone

cannot meet the enhanced energy demands.

Oxygen debt

So how do muscle cells get the extra

energy they need? They get it by

working anaerobically.





Anaerobic respiration

produces lactic acid

(waste product),

which accumulates in

the muscles and

causes muscle

fatigue and cramps.

Running the 1500 metres

will build up an oxygen debt

Oxygen debt

This extra oxygen needed to neutralise

the harmful effects of anaerobic

respiration is called an oxygen debt.



In order to get the extra oxygen to 'pay

back' the debt, the body continues to

breathe deeply for some time after

vigorous activity has ceased.



When all the lactic acid in the muscles is

broken down the oxygen debt has been

repaid and normal aerobic respiration

resumes.

Benefits of Improving Oxygen

Transport System

1. Regular exercise is very good for the heart

and lungs: it increases the size of the heart.

2. The lower your heart rate the fitter you are

and it will take longer to reach to maximum

heart rate.

3. After exercise the fitter you are the faster

your pulse will return to normal.



You can measure your heart rate by

checking your pulse in your neck or wrist.

A normal resting heartbeat is around 50 to

80 beats per minute.

Cardio-respiratory endurance

Is the ability of the heart and lungs to

get oxygen to the muscles, so that

the muscles can perform for a long

time









Give specific examples of 2 aerobic

Effects of Cardio-respiratory

Endurance on Performance



Effective cardio-respiratory endurance

is the ability to transport sufficient

oxygen to the working muscles during

sustained exercise.



In activities that last relatively long

periods of time, improved cardio-

respiratory endurance provides you

with the chance to perform better by

being able keep skill level high.

Measuring CRE Standard Test

12 MINUTE COOPER TEST



Aim: To calculate your level of cardio-respiratory

endurance by applying a time/distance formula



Equipment: A flat area and markers



Test Procedure: 12 minutes to cove the maximum

distance possible through

running, jogging or walking.

400m track with markers 10m

apart



Test Calculation: Use table on following slide

Fitness Test: 12 Minute Cooper Test.



Fitness testing gives you specific information

which you can:

• Compare your results with peers

• Compare with Norms (National Average)

• Easy to set up and do

• After re-testing it allows you to see if you have

improved

Calculating your maximum heart

rate and training zones

Your maximum heart rate (MHR) is the

highest number of beats per minute your

heart can reach during all-out effort.

Because maximum heart rate decreases as

you get older, a popular calculation used

is: 220 - age = MHR



For example, a 15-year-old male would

have an MHR of 220 - 25 = 205 beats per

minute.

Calculating your maximum heart

rate and training zones

Once you have calculated your MHR, it is then

possible to calculate your heart rate training

zones, which are as follows:



Zone % MHR Description

1 60 - 65 Easy running, recovery

training

2 65 - 70 Endurance base training

3 70 - 75 Aerobic capacity training

4 80 - 85 Lactate threshold

training

Calculating your maximum heart

rate and training zones

Take your MHR and multiply by 0.60

and 0.75 to determine your aerobic

training zone.



If your MHR is 205, you would

multiply that number by 0.60 and 0.85

to determine what your aerobic

training zone (which would be 123 to

174 beats per minute).

Training to Improve CRE

Once you know your starting level of

CRE (above average, average or below

average) you can consider what type

of training exercises are best.



It is important to realise that your

training becomes more demanding as

time goes on.



What is this principle of training known

as?

Continuous Training

Any exercises (e.g.. running, swimming,

cycling) that ensures that the heart rate is

operating in your training zone for

approximately 20 to 30 minutes for 3 to 4

sessions per week.



Benefits



1. Develops cardio-respiratory endurance

2. Develops aerobic capacity

3. Straight forward to plan

4. Progressive overload achieved by exercising

more often, by exercising faster, or by

training longer. (Frequency, Intensity,

Fartlek Training (Varied Pace Running)

Continuous running or swimming with short

sprint bursts followed by a slower

recovery and then more continuous paced

running or swimming.



Benefits



1. Develops both aerobic and anaerobic

fitness through continuous running and

short speed endurance sprints

2. Can be varied to suit your own

requirements.

3. Progressive overload achieved by

exercising more often, by exercising

faster, or by exercising longer.

in a training session e.g.. 30 mins to 35 mins.

Monitoring the Effectiveness of

CRE Training

You can monitor your progress when

exercising by checking your pulse

regularly to see if it is in your aerobic

training zone.



The easiest way to check your pulse is

to check your heart rate during

exercise for 6 seconds then multiply

this number by 10 to get your heart

rate per minute.

Benefits of Improved CRE

1. Regular exercise is very good for the heart

and lungs: it increases the size of the heart.

2. The lower your heart rate the fitter you are

and it will take longer to reach maximum

heart rate.

3. After exercise the fitter you are the faster

your pulse will return to normal.



You can measure your heart rate by

checking your pulse in your neck or wrist.

A normal resting heartbeat is around 50 to

80 beats per minute.

Muscular Endurance

Muscular endurance is the

ability of muscles to work

continuously.



To improve your muscular

endurance you need to work

muscle groups for long

intervals at a relatively low

level of intensity.



A rower uses mainly the

arms and shoulders. This is

The Effects of Increased Muscular

Endurance on the Body

Improved muscular endurance

should ensure that you have better

muscle tone and posture.



This often means that you are able

to complete skills more effectively

(improved control and fluency),

especially when you get tired.

Sit Up Test Protocol

It is important to monitor training:

• To avoid over-training

• To see if your training is working





One way to see if your training is working is

to re-test yourself (Sit-Up Test) after so

many weeks of training.

Another way to see if your training is

improving is if your performance during your

activity is improving.

The Effects of Increased Muscular

Endurance on the Body

There are many performance benefits of

muscular endurance. Some of these benefits

will be specific to different activities, but in

general improved muscular endurance should

ensure that you have better muscle tone and

Strength

Strength is the maximum amount of

force a muscle, or group of muscles,

can exert in a single effort



The three main types of strength are:



1. Static

2. Explosive

3. Dynamic

Examples of the Three Types of

Strength

A scrum in rugby would be an example of_____

strength:

Static: players using their static strength to stop

other team pushing the scrum.



Throwing a javelin would be an example of_____

strength:

Explosive: Explosive strength is used in single

actions when maximum energy in needed.



Swimming short distances would be an example of

_____ .

Dynamic strength as a swimmer will continuously

work the arm and shoulder muscles to gain

Measuring strength

There are various test for measuring static,

explosive and dynamic strength.





A grip dynamometer is used to measure

static strength in the hand and forearm.

A standing long jump test is often used to

measure explosive strength (power).

For dynamic strength various exercises such

as sprint starts and press ups are often

used.

Training to Improve your Strength

Weight training is an effective way to

improve all types strength. Exercises

will vary according to the type of

strength requiring improvement (static,

explosive and dynamic).



When completing a weight training

programme you need to consider how

many repetitions and sets of different

exercises to complete.

Strength Training



To improve your strength you need

to work muscle groups for short

intervals at a relatively high level of

intensity.



High Resistance (Heavy Weights)



Low Repetitions (Lifting weights 4 or

5 times in a row)

Weight Training

Isotonic exercises in which you move the

weight through the range of movement

required. Useful for developing dynamic

strength (2 handed curl with weights).

Isometric in which you hold and resist against

weight (Hold body in press up position).

Useful for developing static strength.

Another way to see if your training is

improving is if your performance during your

activity is improving.

Muscle Contractions



There are 3 types of muscle contractions:



1. Isometric (exercises are used when

muscles are required to be stable and

still)



2. Isokinetic (exercises are used to when

muscles require control through a

range of movements)



3. Isotonic (exercises involve the same

weight but the muscles involved either

The Effects of Increased Strength on

Performance

There are many performance benefits

to strength. These benefits will be

specific to different activities.



Improved strength should ensure that

you have the capacity to complete

actions which require strength and

co-ordination; e.g., hitting a long pass

in football.

Strength Tasks

1. Think of an individual activity where you

need upper body strength. Give a

description of why you need upper body

strength.

2. Think of a team activity where you need

upper body strength. Give a description of

why you need upper body strength.

3. Think of an individual activity where you

need lower body strength. Give a

description of why you need lower body

strength.

4. Think of a team activity where you need

lower body strength. Give a description of

why you need lower body strength.

Speed

Speed is the ability to cover a distance or

perform a movement in a short time. It can

involve your whole body or just one group of

muscles.









Most activities require speed in some way. To

improve your speed you need to work muscle

The Effects of Speed on Performance

In many team and individual activities

speed is required by the whole body; on

other occasions only part of the body is

required.



Give examples of team activities that you

need to use whole body speed?

A winger in football needs speed to get

away from defenders.



Give examples of individual activities that

you need to use whole body speed

Gymnastics, speed is required when

running into a box to gain maximum height

The Effects of Speed on Performance



• Give an example of a team activity that only

requires part of the body would be?

Badminton doubles, players need speed to get

to the net quickly to return shots at the net.



• Give an example of an individual activity that only

requires part of the body?

Table tennis, players need to bring their arm

forward quickly when playing a forehand

smash.

Speed

Speed is a mix of physical fitness and technique.

For example, to run quickly you need strong leg

muscles as well as a good stride pattern and

running style.



In your SG course give examples of skills in

different team and individual activities, which

require speed? Identify whether it is the whole

body or part of the body which requires speed

in each example you choose.

Measuring Speed

Fitness Test: 30 metre sprint test.



• You must run 30 metres in a straight line.

• Your partner would time your run.

• This would be completed 3 times.

• Your time would be the average of the 3

times.

Understanding Fitness Tests

Fitness Test: 30 metre sprint test.



Fitness testing gives you specific information

which allows you to:

• Compare your results with peers

• Compare with Norms (National Average)

• Easy to set up and do

• After re-testing it allows you to see if you have

improved

Principle of Training: Specificity



When training to improve any aspect of

fitness it is important to train within that

activity. This would allow you to develop

specific skills and movements that you

use during the activity.

Training to Improve your Speed

Speed can be improved through training.

You must increase muscle strength and the

range of movement in your joints by

working on your flexibility.



When training to improve speed you mostly

use anaerobic (without oxygen) energy. Its

important when training to improve speed

that you ensure that your rest and recovery

time is long enough.



This is known as work/rest ratio.

Work/Rest Ratio to Improve your

Speed

1(work):4(rest) 1/4



For every sprint you do you would rest for

4 times as long. Rest is necessary as it

allows time for the reduction of oxygen

debt and the removal of lactic acid.



E.g. Sprinting for 10 seconds and resting for 40

seconds.

Interval Fitness Training

Includes exercises that allow a work/rest

interval to be worked out easily. Interval

fitness training is useful because it allows you

to work hard ( at high intensity) followed by

periods of rest. This helps you work for a long

time without getting to tired.



Benefits



1. Enables high intensity work to be undertaken

with limited fatigue occurring

2. Develops both aerobic and anaerobic activity.

It is important to monitor training:

• To avoid over-training

• To see if your training is working





One way to see if your training is working is

to re-test yourself (30m sprint test) after so

many weeks of training.

Appropriate training methods will have a

positive effect on performance levels specific

to the activity

Monitoring the Effectiveness of

Speed Training

When working on your speed fitness, it is

useful for you to recognise that certain

inherited factors (such as the number of fast

twitch muscle fibres) and other factors (such

as your body shape), will affect

improvement.

The effects of Increased Speed

on the Body

There are many performance benefits of

improved speed. Benefits should be

specific to the activity you participate in.



Think of an activity where you need speed. How

would you becoming faster improve your and your

teams overall performance?

Power



Power is the combination of strength and

speed.



Power is very important in explosive events;









Power can only last for a few seconds.

The Effects of Power on

Performance

In many activities power is required; for

example, in the long jump and shot putt in

athletics. It is also needed in different

kicking and striking actions; for example,

kicking for distance in rugby and batting in

softball.



In your SG course give examples of skills in

different team and individual activities, which

require power?

Measuring power

There are various standard tests for

measuring power. In both of these tests

explosive power is created by powerful leg

muscles.



Power can be improved by undertaking a

training programme. This would include

speed work and exercises to improve the

strength of muscles.

Training to Improve your Power



Explosive power is best improved by

increasing strength in the main muscles

used for different activities and by

completing exercises requiring speed.



One method of training to improve

power in Plyometric Training:

Plyometric Training

Plyometrics is a form of exercise which links

strength with speed of movement.



There are two phases of muscle contraction

during the running or jumping motion. Muscles

go through a stretch (eccentric) phase and a

contraction (concentric) phase.



Very simply, plyometric exercises train your

muscles to store more elastic energy during the

eccentric (lowering/stretching) phase. This is

achieved by the rapid and intense jumps done in

a typical plyometrics workout.

• To avoid over-training

• To see if your training is working





One way to see if your training is working is

to re-test yourself (Standing Broad Jump)

after so many weeks of training.

Appropriate training methods will have a

positive effect on performance levels specific

to the activity

The Effects of Increased Power

on the Body



There are many performance benefits of

improved power. Some of these benefits will

be specific to different activities, but in

general improved power should ensure you

have the capacity to complete actions which

require co-ordination.





Think of an activity where power is needed.

Give 4 examples of how increased power

would benefit your performance.

Flexibility

Flexibility is the range of movement

across a joint.









Most activities require flexibility.

Having good flexibility reduces the

chances of straining or pulling

The Effects of Flexibility on

Performance

In many activities flexibility is required; for

example, when hurdling in athletics and

when swimming back crawl.



The hurdler needs hip flexibility in

particular, as this will help the hurdler clear

the hurdles with minimum effort and

maximum efficiency.



The swimmer needs back flexibility to help

when pushing off, and arm and shoulder

flexibility to produce a wide range of

Two types of flexibility

There are two types of flexibility:

static and dynamic flexibility:



Static flexibility is necessary when you

are holding a balance e.g. in

gymnastics.

Dynamic flexibility is a fast action that

is not held for any length of time. An

example would be a volley in football

Training to Improve Flexibility

Exercises to maintain and improve

flexibility are usually either static or

dynamic.



To improve static flexibility you would

hold a stretch for at least 20 seconds.



To improve dynamic flexibility you

would use ballistic stretching

(stretching on the move) exercises

(spry session).

positive effect on performance levels specific

to the activity

Benefits of Improved Flexibility

• Improved Physical Performance and Decreased Risk

of Injury

A flexible joint has the ability to move through a

greater range of motion and requires less energy to

do so, while greatly decreasing your risk of injury.



• Improved Skilled Performance



• Improved Muscle Coordination



• Increased Blood and Nutrients to Tissues

This allows greater elasticity of surrounding tissues

and increases performance.

Skill Related Fitness

Aspects of skill related fitness include:



• Agility

• Reaction time

• Balance

• Co-ordination

Agility

Agility is the ability to mover the body

quickly and precisely. Agility requires

both flexibility and speed.



In most activities it is an advantage to

be agile; e.g.., when avoiding a tackle

in rugby, dribbling at speed in indoor

hockey or reaching a low net shot in

badminton.



Improved agility will help you react

quickly in ways which are often

Reaction Time

Reaction time is the time taken between

the recognition of a signal and the start

of the movement. It is closely linked to

speed.



Reaction time is the length of time it takes

you to respond to a stimulus. E.g. to start

when the gun goes off in the 100m sprint.



A fast reaction time in basketball, when

marking the attacker, and quick court

movements, would assist in effective

Balance

Balance is the ability to retain the centre of

gravity over your base of support. Balancing

requires the control of different groups of

muscles.



Two types of Balances:

* Static (maintain a balance e.g. gymnastics)

* Dynamic (maintain a balance under

constantly changing

conditions e.g. skiing)

Co-ordination

Co-ordination is the ability to control and combine

movements smoothly and fluently. To perform in a

co-ordinated way, groups of muscles work in a

specific sequence to create effective movements.



E.g. You need strong arm, shoulder, abdominal and

back and back muscles to throw the javelin.



However, in addition to explosive power you

require co-ordination so that your explosive power

is used at the correct stage of the throw and to its

maximum potential.



For difficult skills with complex co-ordination

requirements, specific practices are required.

Co-ordination



As your co-ordination improves you are

able to move your joints and muscles in

the correct order.



Improved co-ordination also improves

control and fluency.

Specificity

Specificity is crucial to physical fitness

performance improvement. Training has to

be specific to your needs; it has to relevant to

that activity, and your existing levels of

fitness and ability.



If you wish to build up strength in the

quadriceps you need to perform exercise

which put stress on that particular muscle. In

other words the more specific the desired

outcome the more specific the training

programme will have to be.

Progression

Almost any increased amount of regular

stress will produce improvement in the body

parts being stressed. The fitter you become

the harder it is to improve their fitness.

Therefore it is important that the overload is

increased progressively.



During any exercise programme it is not only

muscles which adapt to greater stresses put

on the body. Bone, ligaments, tendons also

have to adapt, their adaptations may take

longer than the more responsive muscles of

the body.

Overload

To improve the fitness of various body systems we

need to overload them. By stressing the cardio-

respiratory system, this will help the heart and lungs

to work more efficiently, thus improving aerobic

ability of the individual. This can be achieved by

either modifying the frequency, intensity and duration

of the exercises.



By increasing the frequency of exercise the you will

be training more often to overload stress on the

muscles.



By increasing the intensity of the exercise would

mean putting stress on the muscles by working

harder.



By increasing the duration of exercise you will work

longer and so prolong the stress put on the muscles.

Reversibility

If you stop training your body will revert back

to the condition it was in before you started

training.

The time this takes to occur depends on how

long you have trained for.

If your training has been short and only for a

few weeks then the training benefits will only

last a few weeks before reversibility occurs.

For training that has taken place over many

months the training benefits last for a longer

period. This is because fitness adaptation takes

a long time to establish.

Once it has been established it takes a long time

before reversibility occurs.

Dangers of Overtraining



With any training session it is important

that you do not over train.



This can be achieved through taking

adequate rest and recovery time during

sessions and by avoiding overtraining

each week.



Over training can be avoided by adapting

the levels of frequency, intensity and

duration within your training.

Methods/Types of Training

For training to be effective you also

need to link the principles of training

to appropriate methods of training.

The most important methods of

training for physical fitness are:



1. Continuous training

2. Fartlek training

3. Circuit training

4. Weight training

5. Interval Fitness training

Continuous Training

Any exercises (e.g.. running, swimming,

cycling) that ensures that the heart rate is

operating in your training zone for

approximately 20 to 30 minutes for 3 to 4

sessions per week.



Benefits



1. Develops cardio-respiratory endurance

2. Develops aerobic capacity

3. Straight forward to plan

4. Progressive overload achieved by exercising

more often, by exercising faster, or by

training longer. (Frequency, Intensity,

Fartlek Training (Varied Pace

Running)

Continuous running or swimming with short

sprint bursts followed by a slower

recovery and then more continuous paced

running or swimming.



Benefits



1. Develops both aerobic and anaerobic

fitness through continuous running and

short speed endurance sprints

2. Can be varied to suit your own

requirements.

3. Progressive overload achieved by

exercising more often, by exercising

faster, or by exercising longer.

Interval Fitness Training

Includes exercises that allow a work/rest

interval to be worked out easily. Interval

fitness training is useful because it allows

you to work hard (at high intensity)

followed by periods of rest. This helps you

work for a long time without getting to

tired.



Benefits



1. Enables high intensity work to be

undertaken with limited fatigue occurring

Circuit Training

Includes



Fixed circuit of set tasks

Multi station circuit. Stations include specific or

general exercises (e.g.. bench jumps, sit-ups,

press-ups)

Planned circuit focusing on specific fitness

development



Benefits



1. Develops both general and specific fitness

2. Progressive overload can be achieved by

decreasing rest intervals or by increasing

repetitions of exercises.

Weight Training

Isotonic exercises in which you move the

weight through the range of movement

required. Useful for developing dynamic

strength.

Isometric in which you hold and resist against

weight. Useful for developing static strength.



Benefits



1. Develops both general and specific muscles

2. Develops muscular endurance as well as

strength and power.

3. Progressive overload can be achieved through

increasing the weight or the number of

1. Light Aerobic Exercise



2. Stretching



3. Practicing Skills

4. Gets rid of lactic acid from muscles

Mental Fitness

Aspects of mental fitness include:



• Motivation

• Concentration



Mental fitness can be the difference

between winning and losing. The most

successful performers have a high

level of mental fitness

Motivation

There are two types of motivation.



• Internal

• External



Internal motivation is your own ‘internal’

motivation. If you are interested and purposeful

in your work, you are far more likely to

progress.



External motivation occurs when your

involvement in activity is for reasons apart from

participation. For example winning money or

Concentration

To perform at a high level you need to pay

attention to some cues and full attention to

others. This is a major feature of performance

in all activities.



If you are not focusing on what you are doing

your performance level is more than likely to

drop.



As such your level of ability will affect what you

can concentrate on. If you are a beginner your

main focus will be trying to complete the skill.

As you improve other factors will be taken into

consideration, such as: court position, opponent

Training Within Activities



By training through the activity you have the

chance to improve physical fitness and skills

and techniques at the same time.



Think of examples that you have used this

method of training throughout standard grade.

Describe how you achieved this and how you

made this more challenging.
