Health, fitness and exercise performance
Health is:
“a state of complete mental, physical and social well being, and not merely an absence of disease or infirmity”
Can be accomplished by: immunisation, balanced diet, exercise, social interaction.
Health, fitness and exercise performance
Fitness is:
“The ability to meet the demands of the environment”.
E.G. how well you can cope with the demands of running a marathon or playing a full game of netball.
Health, fitness and exercise performance
Performance is:
“how well a task is completed”
Exercise is:
“a form of physical activity done primarily to improve ones health and physical fitness”.
Health, fitness and exercise performance
Cardiovascular fitness is:
“the ability to exercise the entire body for long periods of time”
It is concerned with the healthy working of the heart, blood and blood vessels.
Helps us to lead an active lifestyle. Why? Allows us to perform/train for longer
How to improve: running etc 60-80% MHR
Health, fitness and exercise performance
Muscular strength is:“The amount of force a muscle can exert against a resistance”
Very important in sports requiring the exertion of great force e.g. weight lifting, sprinting, shot putt.
How to improve – weight training/resistance training. Muscular endurance is:
“The ability to use voluntary muscles many times without getting tired”
Very important in sports requiring stamina such as; long distance running, triathlons or football.
How to improve – circuit training
Health, fitness and exercise performance
Flexibility is:“The range of movement possible at a joint”
Very important in activities using stretching movements such as gymnastics. Also helps reduce risk of injury.
How to improve – static, dynamic, PNF Body composition is:
“The percentage of body weight which is fat, muscle and bone” Important as body composition may influence how well suited
you are to a particular sport. E.g jockey benefits from being light/rugby player from being
heavy.
Skill related fitness
Agility is:“the ability to change the position of the body quickly and to control the movement of the whole body”
Gymnastic floorwork and back somersaults are good examples of activities for which agility is a priority.
Games players will use it to beat an opponent
Skill related fitness
Balance is:
“the ability to retain the centre of mass (gravity) of the body above the base of support with reference to static – stationary – or dynamic changing conditions of movement, shape and orientation”
E.g handstand (static), dribbling in football (dynamic balance)
Skill related fitness
Co-ordination is:
“the ability to use two or more body parts together” Different sports require different types of co-ordination e.g.racket sports require good hand – eye co-
ordination Foot – eye co-ordination will be required when striking
a ball in a football match.
Skill related fitness
Power is:
“the ability to do strength performances quickly.
Power = Strength x Speed
Throwers need to be powerful but strength alone is not enough they need speed in their throwing action to generate power. A 100m sprinter will also require power to get out of the blocks quickly.
Skill related fitness
Reaction Time is:
“The time between the presentation of a stimulus and the onset of a movement”
E.g. reacting to the starters gun in the 100m or to a shuttle which has been smashed into your half of the court.
Skill related fitness
Speed is:“the differential rate an individual is able to perform a movement or cover a distance in a short period of time”
Speed is an essential ingredient in most sports E.g. leg speed for a 100m sprinter or speed of
limbs and thought for a boxer.
Diet, Health and Hygiene
7 requirements of a healthy diet
Carbohydrates Proteins Fats Vitamins Minerals Water Fibre
Diet, Health and Hygiene
Carbohydrates Maintain our bodies energy stores Two types of carbohydrates = starch + sugars Bread, pasta, rice and potatoes are good sources of
starches. It is carbohydrates which provide use with most of our
energy when taking part in sport Endurance athletes will need to consume large
amounts of carbohydrates in order to keep their energy levels high
Diet, Health and Hygiene
Protein Protein is essential for the growth of muscle
and the repair of damaged tissue Foods rich in protein include, poultry, fish, milk,
cheese, eggs, lentils and beans. Weight lifters, sprinters and other sportsmen
and women requiring large muscle mass will need high protein diets
Diet, Health and Hygiene
Fats Fat is important because it provides energy
and helps other things work such as fat soluble vitamins.
Energy provided from fats should be considerably less than from carbohydrates
Foods rich in fats include, butter, cream, oils etc.
Diet, Health and Hygiene
Vitamins We only require vitamins in small quantities Important for: good vision, good skin, red blood
cell formation, healing, healthy bones + teeth. Sources of vitamins include: Vitamin A – milk, cheese, carrots Vitamin B – whole grains and nuts Vitamin C – Found in fruits
Diet, Health and Hygiene
Minerals Are used by our bodies for a variety of
functions. Calcium: formation and maintenance of bone
and teeth (milk, cheese and cereals) Iron: Important for bloods ability to carry
oxygen (iron is found in a range of foods most easily absorbed is in meat)
Diet, Health and Hygiene
Water Transports, nutrients, waste, hormones It is the main component of many cells Helps regulate body temperature Boxers and marathon runners need liquid
during their exertion in order to offset dehydration
Diet, Health and Hygiene
Fibre It is vital in the functioning of the digestive
system Good sources of fibre include, wholegrain
breads and cereals, oats, fruits and vegetables
Diet, Health and Hygiene
Overweight - having weight in excess of normal. Not harmful unless accompanied by overfatness
OverfatOverfat – having too much body composition as fat Obese –describes people who are very
overfat
Diet, Health and Hygiene
A persons diet will often be affected by the sport for which they are training.
I.e. a marathon runner or decathlete will have to consume large amounts of carbohydrates in order to maintain energy levels
A weight lifter or heavy-weight boxer will need a diet containing large amounts of protein to maintain and build muscle mass.
Whilst a Jockey may need to monitor his diet closely to avoid putting on weight.
Diet, Health and Hygiene
Under eating will result in a loss of body weight and may have a negative effect on performance as the athlete may have low energy levels, or lack of muscle mass
Overeating will increase body weight and may make you less agile, flexible and reduced endurance
Diet, Health and Hygiene
Somatotypes (body build/physique) Measurements taken from height, weight, bone
size, muscle girth and fat Endomorph Mesomorph Ectomorph Certain body types are particularly suited to
different sports!
Diet, Health and Hygiene
Endomorph Characteristics: Fatness,
round body shape, large build.
Effect on sport: often not suited to endurance events, most commonly found in events requiring large body mass and strength, such as sumo.
Diet, Health and Hygiene
Mesomorph Characteristics: muscular,
broad shoulders, triangular body shape
Effect on sport: Most sportsmen are mesomrophs as most sports require strength and power. Strongmen and sprinters are good examples.
Diet, Health and Hygiene
Ectomorph Characteristics: Thin,
lean, low body fat levels Effect on sport: often
found competing in endurance events such as the marathon and sports requiring a light body such as jockey
Diet, Health and Hygiene
Smoking – Damages heart and lungs and raises blood pressure, increased risk of cancer, heart disease
Reduces bodies ability to carry oxygen so performers suffer from fatigue and loss of breath more easily.
Alcohol – Can cause damage to the liver and brain cells and increase likelihood of dehydration
It may affect performance by impairing judgments, slowing reaction times and causing dehydration, it is commonly used as a sedative in sports such as archery to improve performance.
Principles of training (Sport)
Specificity is:
“doing specific types of activity or exercise to build specific body parts”
E.g The training you do must be specific to the area you are trying to improve or the sport you play
Principles of training (sPort)
Progression is:
“starting slowly and gradually increasing the amount of exercise done”
E.g. training more often or training at a higher level
Principles of training (spOrt)
Overload :
“Fitness can only be improved through training more than you normally do”
Principles of training (spoRt)
Reversibility:
“any adaptation that takes place as a consequence of training will be reversed when you stop training”
If you stop training or train less effectively you will begin to lose fitness
Principles of training (sporT)
Tedium or boredom
FITT Principle
F – Frequency
How many times per week you need to train in order to improve fitness.
3 times per week is normally recommended However, If you are training for a marathon or
playing professional sport you will need to increase the frequency
FITT Principle
I - Intensity
How hard you train The intensity you train at must be sufficient to
increase fitness. E.g cardio vascular fitness requires you to train
at an intensity that will take your pulse into the target range
FITT Principle
T – Time
How long each session must be in order to be of any benefit and to achieve improvement
It is recommended that in terms of cardio vascular fitness 20 minutes should be spend working in the target range.
Elite performers will obviously train for much longer periods
FITT Principle
T – Type
What sort of training you will do For most people this could be a wide variety of
activities to take them into the training zone e.g. swimming , cycling, jogging
Elite performers will do activities specific to their sports or events.
Methods of Training
Interval training Periods of work followed by periods of rest E.g. run for 60 secs rest for 30 secs Used in many different sports (particularly team
games) Advantages to sport: replicates activity, takes
place over short bursts, includes a rest period for recovery, includes repetitions of high quality
Methods of Training
Continuous training Continuous training without rest periods Particularly useful for improving cardiovascular
fitness Commonly used by distance athletes Advantages to sport: cheap, work individually
or in a group, improves aerobic fitness, can be adapted to suit the individual.
Methods of Training
Fartlek Training ‘Speedplay’ a combination of fast and slow
running. You may sprint for 200m then jog 200m then
walk 200m and repeat Advantages include: can be done on a variety
of terrain, can be flexible, useful for sports requiring changes of speed e.g. 1500m
Methods of Training
Cross training Is a mixture of activities adapted to suit an individuals
needs. E.g. one day swimming, one day cycling, one day
running. Might not be suitable for elite athletes but is a good
way of maintaining general fitness. Advantages include: varied certain muscle groups can
be rested, training can be adapted to weather conditions
Methods of Training
Circuit training Involves a number of exercises set out at a ‘station’ so
you avoid working the same muscle groups consecutively.
Improves muscular endurance, cardio vascular fitness and circulo-respiratory fitness.
Advantages: offers good all round fitness, cheap, people of all levels can work at their own pace, both aerobic and anaerobic, varied, works a number of different areas.
Methods of Training
Weight Training Weight Training is a form of training that uses progressive
resistance, either in the form of actual weight lifted or in terms of the number of times the weight is lifted.
Weight training is used for: Increase muscular strength Increase muscular endurance Increase speed Develop muscle bulk or size Rehabilitate after illness or injury
Methods of Training
Personal Exercise Program (PEP) A personal exercise program is a training plan
designed to improve a persons health, fitness and performance and is made to suit their individual needs
PEP must use principle of training e.g. overload, progression specificity and the FITT principle
Methods of Training
Individual needs It is important the training program is planned around
the individual One person may like swimming but another may not be
able to swim So activities must be suitable A midfielder in football will require a different training
program to a defender or a goal keeper because their needs are different
Methods of Training
Training sessions include: A warm up – to prepare the body and mind -
Pulse raiser, stretching and activity related work e.g. sprints/shooting
Main activity – practice skills, work on fitness etc
Cool down – Bring HR back to normal by gentle jogs and stretches
Methods of Training
Immediate effects of exercise Increased HR Increased breathing Increased body temperature Sweating Muscle fatigue / tiredness
Methods of Training
Effects of regular training and exercise Increased stroke volume and cardiac output
(so heart pumps more blood per beat) Quicker recovery rate Lower resting HR More efficient CV system Increase number of capillaries
Methods of Training
Long term benefits of exercise Lower blood pressure Reduced risk of coronary heart disease You can work harder for longer
Methods of Training
Target Zone Used as a guide to measure intensity of
exercise, and can be worked out in the following way:
Max HR = 220 – age Lower end of target zone will be 60% of max
HR Top end of target zone will be 80% of max HR
Methods of Training
E.g. 220 – 20 = 200 bpm (max HR)
Low end target zone is 60% of 200 bpm = 120 bpm
Top end target zone is 80% of 200 bpm = 160 bpm
Therefore the target zone is 120 – 160 bpm
Aerobic (with air) activity Any sustained activity
requiring increased breathing and oxygen consumption
Aerobic activities normally last for a minute or more
Increases cardio - vascular fitness and efficiency of respiratory system
E.g. long distance running
Anaerobic (without air) activity
Anaerobic activities are high intensity activities over a short period of time
They only last for 40 second or so, even the fittest athletes cannot work at this intensity for longer
Examples include 100m sprint

the body for use.
The right side right side pumps deoxygenated blood to the lungs to pick up oxygen.
From the body
The Circulatory system
Blood flows around the body in a ‘figure of eight’ circuit, passing through the heart twice on each circuit. Hence the name the Double Pump System.
There are 2 separate ‘loops’ to the circuit:
The top loop – carries blood from the heart to the lungs and back.
The bottom loop – carries blood from the heart to all over the body and back.
(A)(A)
(V)(V)
Heart
Body
Lungs
The Circulatory system
Heart rate is: “The number of times the heart beats each minute”
During exercise your HR will increase With continued training your resting HR will be lower as
your heart is stronger and more efficient Stroke volume is:
“the volume of blood pumped out of the heart by each ventricle during one contraction”
At rest stroke volume may be 85ml, but when exercising it will increase up to 130ml
The Circulatory system
Cardiac output is:
“the amount of blood ejected from the heart in one minute”
Cardiac output is governed by the HR and stroke volume
Cardiac output = stroke volume x HR When you train your cardiac output will increase
because your heart is be bigger, stronger and more efficient
The Circulatory system
There are three main types of blood vessels Arteries Veins Capillaries
The Circulatory system
Arteries Veins Capillaries
Thick walls Much thinner walls than arteries
Microscopic vessels
Carry oxygenated blood away from the heart
Carry deoxygenated blood to the heart
They link the arteries with the veins
More elastic than veins Less elastic than arteries At one end they carry arterial blood which transfers oxygen and nutrients to the muscles
Cope with higher blood pressure
Carry blood at lower pressures
The channel the blood passes through (lumen) widens to cope with increased blood flow during exercise
They contain many valves to stop blood flowing backwards, as venous blood is often flowing upwards against gravity
At the other end, they pick up waste and carry venous blood into the veins as they pass through the system
The Circulatory system
Blood structure: Plasma It is the liquid part of the blood Its functions include transporting:
Glucose from the small intestine to the cells for use in energy production.
Transporting carbon dioxide away from cells to the lungs for removal from the body.
Other waste products away from cells for removal from the body, e.g. urea and heat when the body is hot.
The Circulatory system
White blood cells These have a nucleus (control centre) and vary
in size and shape Function includes: protecting the body from
disease by
Engulfing any invading microbes, defending the body from disease.
Producing antibodies which help the body attack disease.
The Circulatory system
Platelets These are tiny pieces of cell which have no
nucleus Their main function is to:
Clump together when blood vessels are damaged and help to clog a ‘meshwork’ of fibres which create a clot, to help stop bleeding.
The Circulatory system
Red blood cells These have no nucleus and are very flexible so
they can pass through the extremely tiny capillaries of the body.
Their main role is to:
Collect and carry oxygen to all the cells of the body so they can create energy.
In order to do this, red blood cells contain Haemoglobin, which combines with oxygen to become Oxyhaemoglobin.
The Respiratory System
Trachea(wind pipe)
Alveoli
Bronchioles
Intercostalmuscles
Ribs
Bronchus
Lung
Diaphragm
The Respiratory System
Inspiration The intercostal muscles
contract pulling the rib cage up and out
Diaphragm contracts causing it to flatten
Chest cavity gets larger causing pressure in the lungs to fall
Air moves into the lungs from the higher outside pressure
Air flowing in
The Respiratory System
Expiration The intercostal muscles relax and
so the rib cage returns to normal The diaphragm relaxes pushing it
up The chest cavity gets smaller so
the pressure in the lungs increases
Air flows out of the lungs During periods of exercise
expiration becomes an active process involving the forced expulsion of air
Air flowing outward
The Respiratory System
Alveoli Are tiny structures were
diffusion of o2 and co2 takes place
Surrounded by capillaries Capillaries have thin walls as
well to allow exchange of o2 and co2
The more training you do the more alveoli become available for gaseous exchange
Thin wall
Capillaries Red blood cells
The Respiratory System
Gaseous exchange1) Alveoli in close contact with blood capillaries2) O2 in alveoli is diffused into blood capillaries3) Whilst the o2 is taken co2 is given out to the alveoli and breathed out4) O2 is carried via circulatory system around the body in the red blood
cells before being deposited in living cells5) O2 is combined with glucose in the cell to produce energy along with
waste products of co2 and water6) The process then begins again when the deoxygenated blood returns
to the lungs7) During exercise there is increased demand for energy and therefore o2,
there is also more co2 produced during exercise which must be removed
The Respiratory System
Inhaled air into the Inhaled air into the

The Respiratory System
Tidal volume
“The volume of air you breath in and out in one breath”
Tidal volume increases during exercise Vital capacity
“the maximum amount of air you can breathe out after breathing in as much air as possible”
The Respiratory System
Oxygen debt
“the amount of oxygen consumed during recovery above that which would have ordinarily been consumed in the same time at rest (this results in a shortfall in the oxygen available)
Bones
Bone Growth
Bone grows from Cartilage in the body, from when we are born.
It hardens with Calcium and other minerals, to form bone, called Ossification.
Bone growth begins at the centre of the bone.
Growth continues at the end of bones, but cartilage remains at the end of bones.
Bones
Composition of bone Epiphsis: End of a long bone. Diaphysis: The Shaft of a long bone. Cartilage: A dense, elastic, connective tissue that
cushions and connects many bones in the skeleton. Periosteum: Tough membrane which surrounds bone. Calcium: A mineral vital for healthy bones, found in
dairy products, eg milk, cheese, yogurt etc…
Bones
Bones
Functions of skeleton Shape – without it we would be a pile of jelly. Support – Allows us to hold positions, standing up. Movement – Allows activity. Blood Production – Marrows within the bone
produces all the vital ingredients of blood. Protection – Protects the vital organs, eg, brain,
hearts, lung etc..
Bones
Classification of bones
1. Long – Lever bones.Eg Humerus, femur, phalanges etc..
2. Short – Small Levers.Eg Carpals, tarsals.
3. Flat – Protecting bones.
Cranium, patella, ribs etc..
4. Irregular – More protection.
Eg Vertebrae, protect the spinal cord.
Bones
Bone forms part of our lean body mass, which relate to weight and can affect performance (Diet and Nutrition Year 10).
Bone determines size of body and length of limb, rugby players, gymnasts, high jumpers.
Bones influences Body Composition and can therefore influence participation and performance in Sport.
Bones
You must also be able to identify the major bones of the body
Remember bone size will determine body size, weight and composition.
This will in turn affect your performance in sport A good diet and regular exercise will help ensure
healthy bone formation and long term health
Joints, tendons and ligaments
A joint is:“a place were two bones meet”
Joints allow use to move freely during everyday life and in sporting activities
Without them our movement would be restricted
E.g. joints in our fingers allow us to grip (a racket, ball etc)
Joints, tendons and ligaments
You need to now the different types of joint Ball and socket (I.e shoulder0 Synovial joint (I.e. knee)
You also need to know the role of cartilage, synovial fluid and membrane (give examples form the knee joint

Muscle types Cardiac muscle cardiac muscle works without you thinking
about it (there is no conscious control) It is only found in the walls of the heart Never tires and important for pumping blood
around body during periods of activity
Muscles and muscle action
Involuntary muscle Also works without you thinking about it Also known as smooth muscle Found in the walls of arteries, veins, stomach
and intestines
Muscles and muscle action
Voluntary muscles You have full control over voluntary muscles● They are also know as striated or skeletal
muscle.● They are attached to bone and cause the
skeleton to move.● Examples include the triceps and hamstrings.● They are the largest group of muscles in the
body
Muscles and muscle action
Antagonistic muscles
Skeletal muscles work across a joint and are attached to the bones by strong cords known as tendons.
They work in pairs, each contracting or relaxing in turn to create movement.
Muscles and muscle action
Flexion (bending) of the arm
The muscle doing the work (contracting) and creating the movement is called the agonist or prime mover. The muscle which is relaxing and letting the movement take place
is called the antagonist.

Prevention of injury
In all sports were competition is part of the game, rules will be in place to protect players, officials and spectators from injury.
How can we make activities safe? Protective clothing Appropriate footwear Balanced competition Weight categories Mixed or single sexed competition Age Groups
Balanced Competition
Another way to make sport safe is to try to level the competition by grading competitors in various ways:
Weight categories – Boxing and Karate. Mixed or single sex competitions – contact
sports. Age groups – football etc. (but not all children
of the same age are the same height or weight)
Sports Injuries
Joint injuries

Sports Injury
Sports Injury
Posture It is important to keep our bodies balanced but we
often stoop or sag. Over time this can lead to problems with posture
resulting in back / neck pain and discomfort It can be caused by slouching in chairs, ill fitting shoes,
poor muscle tone, flexibility and being overweight.
Sports Injuries
How can we improve our posture? Strengthen muscles Increase flexibility Loose weight Sit upright Avoid slouching Wear well fitting shoes.
