The hinge joint allows flexion The Skeleton protects vital organs and extension The Cranium (Skull) protects the brain The type of bone and joint The ribs and sternum protects the heart and lungs determine the movement Joints allow movement Movement Protection 1a) Skeleton The Four Functions Bone marrow produces red and white blood cells Blood Production Red blood cells carry oxygen in haemoglobin to working muscles White blood cells prevent infection / fight disease Support The skeleton gives the body its shape Muscles are mainly attached to the bones on the outside of the body. While the vital organs are attached to the inside Cranium Cervical (vertebrae) Clavicle Scapula Humerus Radius Pelvis Carpals Ulna Phalanges Femur Patella Tibia Tarsals Metatarsals Fibia Phalanges Skull (Cranium) There is no movement in these joints Examples Pelvis No Joint Cavity Fixed or Immoveable Joints 1a) Skeleton - Joints Slightly Moveable Joints No joint cavity Sternum Examples Some movement Ribs These are joints which allow movement, they contain a joint cavity Strong connective tissue which holds bones together at joints Ligaments 1a) Skeleton – Freely Moveable Joints (Synovial Joints) Cartilage Produce synovial fluid Reduce friction Articular Found at ends of long bones Is found in all joints There are two main types Found between vertibrae Fibro Act as a shock absorber Rotation Ball and Socket Allows a full range of movement – flexion and extension / circumduction / abduction and adduction Gliding Pivot Hinge Flexion and extension 1a) Skeleton – Feely Moveable Joints (Synovial Joints) Condyloid Rotation / flexion and extension Saddle Rotation Types of movement Sporting example Heading the ball in football Types of movement Hinge (Knee and Elbow) 1a) Skeleton – Joints and Sport Specific Movements Badminton Gymnastics Pivot (Neck) Flexion and extension Sporting example Condyloid (Wrist and Ankle) Sporting example Netball shot Kicking (football / rugby) Ball and Socket (Hip and Shoulder) Tennis Serve Types of movement Types of movement Rotation / flexion and extension Abduction and adduction / flexion and extension / circumduction Darts Sporting Example Cricket Bowling Deltoid Pectorals Triceps Trapezius Biceps Latissimus Dorsi Abdominals Quadriceps Gluteus Maximus Hamstrings Gastrocnemius Also known as Anaerobic activities Sprinting Weight lifting Sporting examples Contract quickly to produce fast and powerful movements, they tire easily Fast Twitch 1b) Muscles – Fast and Slow Twitch Muscle Fibres Slow Twitch Contract slowly with little force but do not tire easily Tour De France Sporting examples Also known as Aerobic activities Long Distance Running Increased muscular endurance Improved Muscular recovery Reduces the chance of injury and increases participation Increased muscular strength How does improved muscle functioning improve performance and participation 1b) Muscles – Effects of Exercise on Muscles Reduced exercise leads to muscle Atrophy (become smaller) This is referred to as Reversibility within S.P.O.R.T and can be caused by injury Composition and efficiency of muscles Increased exercise = increased strength Increased exercise = increased muscular endurance Muscles become bigger Muscle growth in known as Hypertrophy Increased exercise = increased flexibility 2) Bicep muscle (also known as the prime mover and agonist) contracts (shortens) 1) Tendons attach muscle to bone 3) Tricep muscle (Antagonist) relaxes (lengthens) 1b) Muscles – Role and Function of Tendons During Movement 4) The bicep pulls on the tendon which in turn pulls on the bone 5) Movement occurs at the elbow (Hinge joint) pulling the forearm up towards the body 6) The muscle actions are reversed to lower the forearm 1) Flexion of the Arm (Forearm Moves Towards the Body) 2) Extension of the Arm (Forearm Moves Away from the Body) Where the tendon joins to the bone. Attach muscle to bone. Origins Stable and does not move. Scapular Tendons Scapular Bicep Movement Origins Tricep Tendons Movement Bicep Tricep Radius Radius Humerus Humerus Ulna Insertions Where the tendon joins to the bone which the muscle can move. Ulna Tendons Allows muscle to pull on the bone to create movement. The Bicep (Agonist) contracts (shortens). The Bicep (Antagonist) relaxes (lengthens). The Tricep (Antagonist) relaxes (lengthens). The Tricep (Agonist contracts (shortens). There are three types of muscle contraction The speed of movement remains the same throughout the action The muscle shortens as it contracts e.g. lifting the bar in a bicep curl Concentric When doing the butterfly stroke in swimming, the arms and legs are moving at relatively constant speeds Isokinetic Isotonic This muscle contraction can be subdivided into two types Eccentric 1b) Muscles – Muscular Contractions The muscle lengthens, but under tension e.g. lowering the bar in a bicep curl Isometric The muscle remains the same length throughout the action. Certain parts of the body need to be kept still while other parts are working In a bicep curl, the back and shoulder muscles are working isometrically to stablalise the body Pushing in a rugby scrum, when there is no movement, is also an example of isometric action Due to all out effort / body cannot cope with intensity of exercise / high intensity Due to working for a long time Not enough oxygen / no oxygen / anaerobic Why the Body Produces Lactic Acid 1b) Muscles – Lactic Acid Sore /painful muscles / stiffness / seize up / stitch How Lactic Acid Affects Performance Reduced performance / skills Lose interest / concentration / motivation Causes oxygen debt / prolonged recovery Increase breathing rate / heart rate Stop / collapse Tired muscles / fatigue Ensures a constant supply of blood where needed throughout the body Blood carries white blood cells to sites to fight infection Blood transports waste products from muscles and other locations in the body e.g. carbon dioxide from body cells to the lungs Blood passes through tubes called blood vessels Consists of the Heart and Blood Vessels 1c) Cardiovascular System Blood contains essential nutrients Oxygen if carried around the system to where it is required to release energy in the muscles Nutrients Oxygen Transport (blood carries) Waste products Functions of the Circulatory system Temperature Control Blood absorbs and transfers heat from warmer to cooler parts of the body Protection (White Blood Cells) Carry antibodies to fight infection Carry platelets to clot blood at wounds and cuts Deoxygenated blood is pumped from the heart to the lungs where it is oxygenated. It is returned to the heart to be pumped around the body in the systemic system. Takes deoxygenated blood from the heart around the body through the arteries. Deoxygenated blood is returned through the veins to the heart. Systemic Circuit 1) Pulmonary Vein: Takes Oxygenated blood from lungs to the LA. Pulmonary Circuit 1c) Cardiovascular System – The Heart as a Double Pump 2) Aorta: Takes Oxygenated blood from LV to the body. Lungs Pulmonary System (Oxygenated Blood) LA 3) Vena Cava: Takes Deoxygenated blood from body to the RA. 4) Pulmonary Artery: Takes Deoxygenated blood from RV to the lungs. Pulmonary System (Oxygenated Blood) RA RV LV Systemic System (Deoxygenated Blood) Systemic System (Deoxygenated Blood) RA – Right Atrium RV – Right Ventricle Body LA - Left Atrium LV – Left Ventricle Tiny tubes, one cell thick Transport blood from arteries to veins Capillaries One exception – Pulmonary artery carries deoxygenated blood between heart and lungs 1c) Cardiovascular System – Blood Vessels Arteries Carry oxygenated blood away from the heart under high pressure Food, oxygen, carbon dioxide and waste products are exchanged through their thin walls Carry blood back to the heart under low pressure Veins Valves in the veins prevent blood flowing backwards, away from the heart A sprinter can recover from all out effort in a matter of minutes Time it takes for lactic acid in the muscles to fall to acceptable levels for muscles to start working efficiently again Recovery Rate Marathon – requires longer periods of recovery before heart rate and respiratory rate return to normal levels 1c) Cardiovascular System – Participation and Performance In longer events fatigue develops much more gradually as the body is able to process some of its lost energy and minimise lactic acid build up during exercise Duration Lactic acid accumulation and oxygen debt is influenced by the duration and nature of an activity Sprinters consume energy very quickly without taking in oxygen (Anaerobic) which means that the onset of fatigue occurs very quickly, within seconds When the rate at which muscles work is greater than the bodies ability to supply oxygen the result is a shortage in oxygen which leads to fatigue The supply of oxygen to our muscles is limited by our capacity to take in oxygen during a performance and how efficiently we get that oxygen to the working muscles Oxygen Debt In order for the muscles to work again efficiently this oxygen debt must be repaid 1c) Cardiovascular System – Participation and Performance Waste product this produces is called lactic acid Builds up quickly in activities requiring all out effort (Anaerobic) e.g. 400 meters Builds up slowly in Aerobic activities e.g. long distance running As muscles work without oxygen lactic acid builds up this causes muscular fatigue, leading to cramp Lactic Acid Anaerobic exercise uses glycogen rather than oxygen Cramp will only subside when the muscle is rested and blood brings fresh oxygen to break down the lactic acid Increased sweating to cool body Increased heart Rate to meet demand for oxygen Increased Stroke Volume – amount of blood leaving the ventricle on each beat Short Term Effects of Exercise Blood diverted to Capillaries just below the skin – causes face to redden Heat from body is radiated from the skin Increased Cardiac Output 1c) Cardiovascular System – Effects of Exercise Long Term Effects of Exercise Increased stroke volume Muscle Hypertrophy (Heart becomes bigger and stronger) Increased Cardiac Output = Stroke Volume x Heart Rate Lower resting heart rate RETIRED SPANISH CYCLIST, MIGUEL INDURAIN HAS A RESTING HEART RATE OF 27 BPM. Platelets to damaged capillary areas Carbon dioxide from body cells to lungs White blood cells to sites of Functions (blood infection Platelets Blood is composed of four elements Oxygen from lungs to body cells carries) White Cells Heat from warmer to cooler parts of the body Plasma Red Cells Blood 1c) Cardiovascular System Blood 92% of plasma is water the remainder is protein, glucose, amino acids and waste products such as carbon dioxide and urea Produced in the bone marrow Platelets Stick together in clumps where the skin is broken, or on small damaged blood vessels Plasma Protein and amino acids are transported to cells in the body and are used for growth and repair. Glucose is used for energy Haemoglobin + Oxygen = Oxyhaemoglobin From the lungs to the working muscles Carry Oxygen – attaches to Haemoglobin Made in bone marrow e.g. Ribs and Femur Red Blood Cells 1c) Cardiovascular System Blood Larger than red blood cells White Blood Cells Made in bone marrow and lymph glands Main function is to defend the body against disease Contain Phagocytes: pass through capillary walls and surround germs – they then produce enzymes which destroy the germs Contain antibodies which fight against germs and infection The Lungs Air Passages The Diaphragm The Respiratory System is made up of 1c) Respiratory System Structure Air Passages A series of Air Passages allow air and the Oxygen it contains to be transferred to the bloodstream Removes Waste Products such as Carbon Dioxide from the body Diaphragm A sheet of muscle which encloses the bottom of the thorax Contraction and Relaxation of the Diaphragm, combined with the Intercostal Muscles enables Breathing Air is taken into the body thorough the mouth and nasal cavity The Trachea branches into two to enter the lungs as Bronchi At the top of the throat is the Epiglottis which prevents food or other particles entering the lungs The Bronchus in each lung divides into Bronchioles 1c) Respiratory System Structure Bronchioles sub – divide into two small air sacs Alveoli The Alveoli are covered with very small vessels, Capillaries, which allow oxygen and carbon dioxide to pass to and from the bloodstream Alveoli is where the exchange of oxygen into the blood and carbon dioxide out of the blood occurs There are two phases in breathing, Inspiration and Expiration Inspiration (breathing in) Expiration (breathing out) The lungs are enclosed in a sealed, flexible cavity called the thorax The diaphragm and intercostal muscles relax Lungs contract to their original size, forcing air out The diaphragm and intercostal muscles contract expanding the chest Although there is no need to think about breathing (it is involuntarily controlled) it can also be consciously controlled Allows the lungs to expand, filling the space created 1c) Respiratory System – Breathing Mechanism Air is sucked down the windpipe and into the lungs Breathing out Breathing in The lungs expand Intercostal muscles contract, pulling the rib cage up and out As the chest expands, the diaphragm contracts. This pulls down and makes the chest larger Intercostal muscles relax, lowering the rib cage and making the chest smaller The lungs are compressed, pushing air out of the lungs up to the windpipe As the chest is made smaller, the diaphragm relaxes, making the chest even smaller During exercise the body needs a supply of oxygen to release energy in the muscles. Respiration must be increased to provide that oxygen and remove carbon dioxide from the muscles The circulatory system transports the oxygen to the working muscles and carbon dioxide to the lungs The respiratory system takes oxygen into the body and removes carbon dioxide 1c) Respiratory System – Respiration and Circulation Links Increased tidal volume “amount of air taken in and out” As physical activity increases, both the breathing rate and heart rate increases to take in and transport oxygen to the working muscles This results in: Increased stroke volume “amount of blood leaving the heart on each beat” Increase cardiac output “stroke volume x heart rate Muscles feel sore E.g. repaying oxygen debt, removing lactic acid Improved efficiency leads to a quicker / more efficient rate of recovery Builds up slowly Possible injury Aerobic exercise Fatigue Effects on performance Reduced performance Anaerobic exercise Recovery Rate Lactic Acid Builds up quickly 1c) Respiratory System – Participation and Performance Increased efficiency of the systems Takes longer to build up oxygen debt Oxygen Debt Can repay oxygen debt quicker / more efficiently Duration The more efficient your respiratory and circulatory systems are the longer you can exercise for Increased efficiency of these systems leads to quicker recovery – repay oxygen debt quicker and remove lactic acid more efficiently Increased participation in physical activity will lead to an overall improvement of the efficiency of the respiratory system Alveole in the bronchioles are supplied with red blood cells Allows haemoglobin in red blood cells to absorb oxygen as well as carbon dioxide, being released by the blood into the alveole through the bronchioles and out of the body through the lungs and mouth Gaseous Exchange 1c) Respiratory System – Effects of Exercise Upon Performance 1c) Respiratory System – Aerobic and Anaerobic Examples You need to master the basic skills before attempting the complex ones Basic They tend to be transferable between different activities 1d) Skill – Basic and Complex Require a higher level of co-ordination and control Complex Require more practice to master and have more scope for improvement E.g. you would spend more time improving your forehand than practicing a basic skill like running Specific to sport / activity – usually nontransferable Examples Crowd Opponents Weather Team mates Skills can be classified in different ways – they can be divided into open and closed skills Affected by the environment and / or external factors OPEN SKILLS Weather not an influence Moving ball not an influence Are not affected by the environment / external factors 1d) Skill – Open and Closed EXAMPLE Hockey Dribble Other players not an influence CLOSED SKILLS EXAMPLE In some sports skills can be both open and closed Gymnastics Vault Tennis Player has to perform the skill whilst watching their opponent, how fast they are approaching, where they are on the pitch – can they shoot or pass to a team mate? The serve is a closed skill Once the ball is in play shots become open skills The floor and vault are regulation standard There is no change in the environment and no other people influencing the execution of the skill Balance The abilities you possess allow you to perform skills at a more advanced level Flexibility Agility Examples Co-ordination Speed Abilities are Genetic. You are born with basic abilities which can be developed. These differ from skills as skills are practised in order to be improved Ability 1d) Skill – How Do Skills Differ From Ability Skill A skill is something that has been learnt, the skill is practised over and over until it is stored in long term memory for future use Examples Reaction time Trampolining – Pike / Straddle FLEXIBILITY Good co-ordination results in consistent contact with the ball and control / accuracy of the shot CO-ORDINATION Tennis - forehand 1d) Skill – Without Basic Abilities the Development of Advanced Skills is Difficult SPEED Hockey – outrunning an opponent REACTION TIME Cricket – Batting stroke AGILITY Badminton Good agility allows you to change direction quickly, cover the court and play a variety of shots BALANCE Gymnastics - beam Without the basic ability of balance it would almost be impossible to perform advanced skills such as a cart wheel or back somersault without falling off the beam There are two different types of feedback 1. EXTERNAL 2. INTERNAL KNOWLEDGE OF RESULTS 1d) Skill – Different Types of Feedback VERBAL FEEDBACK TO DEVELOP PERFORMANCE KNOWLEDGE OF PERFORMANCE (HOW A MOVEMENT FEELS) VISUAL When does feedback occur? 1. CONCURRENT During performance of the skill Feedback is internal and external 2. TERMINAL Immediately after performance has finished Feedback is external 3. DELAYED Up to 48 hours after performance is finished Feedback is external Were you successful? INTERNAL: How the skill feels when it is performed Knowledge of results 1. CONCURRENT (During performance of the skill) 2. TERMINAL (Immediately after performance) EXTERNAL EXTERNAL Visual Verbal feedback from coach Verbal 1d) Skill - Feedback Knowledge of Results Highlight positives about performance Feedback from coach 3. DELAYED (Up to 49 hours after performance) VISUAL Analyse performance using video analysis Identify areas for development – give specific feedback on how to improve VERBAL Discussion with coach Perform the whole skill (e.g. tennis serve) – practice part of the skill (e.g. ball toss) – practice the whole skill again (e.g. tennis serve) Observe a role model performing a skill and repeat it Skill is performed over and over again for a long period of time Whole-Part-Whole Role Models Massed Practice 1d) Skill – How do we Learn Skills? Trial and Error Distributed Practice Copying Skill is performed over a short period of time Trying to perform a skill then making adjustments to performance based upon external and internal feedback Observe the skill being performed by a teacher, coach or elite athlete and copy their technique It is followed by a period of rest Skill is performed again for a short period of time The difference between the novice and the top level performer is obvious when looking at their skills Adaptability: Struggle to adapt skills to suit different situations Adaptability: Able to adapt skills to suit different situations Time: Reduced time available to train due to factors such as work commitments NOVICE PERFORMERS 1d) Skill – Novice and Top Level Performers Energy: Reduced fitness levels due to reduced training Consistency: Mistakes are frequent Time: Increased time available to train, often their sport is their job, they get paid TOP LEVEL PERFORMERS Energy: Increased fitness levels allows performance to continue at a high level for duration of activity Consistency: More accurate, perform skills to a high standard even if placed under pressure Enables sense to be made of all the information available, so that only useful information is acted upon Selective Attention Venus watches the oncoming ball INPUT (sensory) DECISION MAKING (shot) Venus gets into position ready to hit the ball 1d) Skill – Information Processing Model (Tennis Shot) Venus gains immediate feedback by watching her shot FEEDBACK (results) MOTOR OUTPUT (action) Venus returns the ball to her opponent “Motivation is the driving force that compels people to do something, such as climb a mountain or revise for GCSE exams” “You do something in order to “You do something because you earn money, win a prize or to get satisfaction from it” please another person” Motivation that comes from within 1. INTRINSIC MOTIVATION Examples The enjoyment of taking part in an activity Motivation that comes from outside 2. EXTRINSIC MOTIVATION 1e) Motivation and Mental Preparation – Intrinsic / Extrinsic Motivation Money Social interaction with friends Personal satisfaction Examples Trophies Medals Playing for your country Fame Houses / Cars “Arousal is about being excited, keen and INVERTED U THEORY mentally ready (or unready) to perform a difficult B task” A At ‘A’ – Competitor is underaroused and as a result performed is reduced / low (e.g. Dyer) C 1e) Motivation and Mental Preparation - Arousal There are different levels of arousal in sport, but too little means improvements might be low, too much might lead to loss of control Note: the optimum point of arousal can differ between athletes and sports For example: the Inverted U for a golfer would be further left than the Inverted U for a weight lifter At ‘B’ – Competitor is at the optimum level of arousal and so performs at a high standard At ‘C’ – Competitor is overaroused and as a result performance is reduced / low (e.g. Zidane) These are techniques to ensure that the athlete reaches their optimum level of arousal (Point B on the Inverted U graph). This will lead to consistent participation and optimum performance 1. FOCUSING You focus your attention on what you need to do to perform well during competition 2. RELAXATION 1e) Motivation and Mental Preparation 3. MENTAL REHEARSAL (VISUALISATION) This is where you go through the event in your mind in advance, in detail. You picture yourself performing well and staying calm and confident Techniques include slow deep breathing and relaxing different muscle groups in turn Gives you confidence when you reach your goal / target MOTIVATION How does it help to control anxiety and motivate participants? ANXIETY Helps you get ready to perform, since you know what you want to achieve “Goal setting means setting targets that you want to reach” Divided into two types Motivates you to work hard to achieve your goals 1. SHORT-TERM Goals that you can reach quickly (short time frame) are steps on the way to…….. 2. LONG-TERM Goals like winning an Olympic medal (long time frame) 1e) Motivation and Mental Preparation – Goal Setting Helps you to feel in control and so you are less anxious about performance SMARTER SPECIFIC – exactly what you want to achieve MEASURABLE – see if you’ve achieved it or not AGREED – agree targets with your coach REALISTIC – goals you an realistically reach TIME-PHASED – so long term goals are reached in time EXCITING – boring goals won’t motivate you RECORDED – so you can monitor your progress People start and finish work at different times Leisure Time is when you are not at school or work, you can do what you want when you want in your free time Flexi working hours and working from home allow people to take part in leisure activities during the day The working week is shorter than it used to be, and it is also more flexible Shorter Working Week At home there are laboursaving devices, reducing the amount of time spent on domestic chores More people work from home rather than in an office, due to computer links Technology 1f) Social Reasons for Participation – Reasons for Increased Leisure Time Early Retirement Increasing numbers of people retire early, many by the age of 50. At this age people still enjoy an active lifestyle and often take up new sports and leisure activities such as golf Machines have replaced muscle power, with production lines controlled by fewer people This all leads to people having more time to spend on Leisure Activities Unemployment Many people are unemployed, or work part time. This means they have more time to take part in leisure activities, although the cost of taking part may prevent them Some local authorities subsidise the costs for unemployed people to encourage then to take part in leisure activities To lose weight To look good Improve stamina, strength, flexibility Medical Necessity Image Physical / Mental Well - Being Reduce Stress Levels Fitness Illness Health Increase Life Expectancy Healthy body allows you to more active 1f) Social Reasons for Participation – Why People Participate in Physical Activities Prevents boredom Leisure Meet new people Learn to relate to people / develop social skills Socialise Enjoyment Helps reduce stress Hobby Gets you out of the house Friendship Make new friends Coaches Life Guard Employment Professional Athlete Vocation Gym Instructor 1f) Social Reasons for Participation – Why People Participate in Physical Activities Will have another form of employment Vocation Semi – Pro Status (amateur performers) Way of earning money but not enough to live off Way of earning money Professional May take part in another activity as a recreation e.g. professional footballers play golf BTEC / Vocational Sports Coaching Awards A – Level PE GCSE PE CSLA Examination Courses JSLA 1g) School Introduces pupils to a variety of activities Students, irrespective of where they live should have similar experiences in PE National Curriculum Requirements Makes pupils more aware of health and fitness issues Physical Education is compulsory Develop an understanding of activities, skills, tactics, safety and benefits of physical activity Club may use school facilities for training / matches. Links between schools and local clubs benefit both the school and the club Students may play for local clubs – providing the club with a constant supply of members Links With Local Sports Clubs Clubs can help school with coaching and by allowing them to use their facilities for training and matches 1g) School Extra Curricular Activities Often include interschool fixtures Links with local clubs Facilities They take place outside of normal school time Factors determining extra – curricular activities Important as they help develop high standards and help talented students to have the chance to play for their county or country Activities included in PE curriculum Interest and skills of teachers Some activities are suitable for all ages such as golf, where skill is almost equally as important as physical attributes Gymnastics – is associated with younger people as the body is more flexible The sport and leisure activities people take part in is often closely related to their age As the body ages flexibility reduces at the joints, sprains and other injuries become more frequent As people get older they take part in sport less and the nature of the activity also changes Walking, green bowling and recreational swimming are some activities enjoyed by 1h) people of all ages In contact sports such as rugby, recovery time after injury takes longer as people age Age Social Background – Positive and Negative Effects More female commentators Gender Social Attitudes Coaching Labour saving devices Reasons for low participation levels Role Models (Fewer women than men take part in sport) Ways in which women are being encourage to participate in sport Media Coverage Finance Increased prize money More female role models More media coverage Socially acceptable to take part in sport Canoeing and sailing as rivers and lakes tend to be found in the country Climbing and abseiling as cliffs and rock faces tend to be found in the country Walking, hiking and fell running common in the countryside Pony trekking, horse riding are common countryside activities Schools play a major part in developing attitudes towards participation in sport Specialist facilities such as fencing clubs are located in cities / towns 1h) Social Background – Positive and Negative Effects Pupils have access to PE as part of the National Curriculum Family play, encouraging participation Some climbing available at specially built climbing walls City Access Education Also have access to examination course such as GCSE and A Level PE Some activities require significant financial investment for equipment and travel Facilities available in cities may differ to those available in the country Country Some water sports may be available in dockland developments Financial support – equipment, transport and clothing Family (major influence in determining interest in sport and leisure activities) By taking them to watch sport By going to watch them play Parents and sibling act as role models Not all Peer Pressure is positive and people could be discouraged from participating due to friends influence Some countries have strong traditions in sport e.g. New Zealand and Rugby Friends may have the same interests playing in school and club teams Can have both a positive and negative influence on participation Tradition and Culture People are often influenced by their friends this is known as Peer Group Pressure Peer Groups Friends may share the same interests in recreational activities such as mountain biking and swimming In the UK there are regional strength e.g. Rugby league in Yorkshire and Lancashire 1h) Social Background – Positive and Negative Effects In the Lake District there are opportunities for many outdoor activities Environment Is a contributing factor to participation and might be sport specific Living in Cornwall may offer the chance to take part in surfing In East Anglia there is no Mountain walking but plenty of water sport activities Politics The Government can influence participation Ensuring time for physical education in schools Providing funding for facilities, coaching and equipment Promoting sport and leisure activities as being beneficial to health T.V. and newspaper coverage of an activity can create the growth Events courage significantly influenced by money / sponsorship e.g. Football Advertise games, events and competitions Influence on Activities Minority sports may not get the same coverage as a result. Note the media can help to increase awareness and participation in these sports Increased opportunity for a career Desire to be like role models e.g. Wayne Rooney, Lewis Hamilton and Amir Khan Some activities require money to access e.g. Sky Sports Media This is not always good as the athlete may set a bad example e.g. using drugs or arguing with referee Role Models Autobiographies and websites make performers more accessible 1h) Social Background – Positive and Negative Effects Newspaper, Radio and T.V. interviews help to create role models More clubs / organised fixtures Disability Easier access to venues / facilities Sport for people with disabilities has changed, with Governing bodies devising rules and activities suitable for all disabilities Society is more aware Increased coverage of Para Olympics – promoting participation Specialist coaches Role Models Increased availability Public transport more accessible Grass Playing Fields Gymnasium Swimming Baths Local Parks Sport Centres Astroturf Swimming Pool School & Collages are Required to Provide Facilities for Physical Education Control Sport and Leisure Facilities Educational Departments Schools Hire Facilities to: Adult Education Playing Fields Leisure Departments Local Authority Community Clubs 1i) Local and National Facilities Concept of ‘Sport for All’ To improve national and international records (excellence) To improve levels of performance in terms of world rankings (medals) UK Sports Council Targets National Authorities Provide the Best Coaches The UK Sports Council Provide High Level Sport Development at a Number of Specialist Centres Around the Country (Centres of Excellence) Provide Sport Psychologists Provide the Best Equipment Help Improve Performance of National Teams / Players by To improve the success of English teams in international competitions. Have the Most up to Date Technology and Medical Care Provide the Best Facilities Some larger hotels have golf courses and tennis courts Have leisure suites with swimming pools, fitness rooms. Many commercial clubs provide a facility which would otherwise not be available, but they exist primarily to make a profit Commercial Sports Clubs Hotels Hotels are often fully booked and local residents are unable to gain access to facilities on a regular basis and when they can it is at a cost Commercial organisations providing sporting facilities for competition and recreation to make a profit Private Enterprise 1i) Local and National Facilities Squash, tennis and golf clubs are examples of private developments There has been a growth in fitness gyms allowing people to access their facilities at varying rates Voluntary Organisations Sports clubs e.g. cricket and tennis clubs provide specialist facilities for their members. Many own these facilities, however new clubs often have to hire facilities from establishments such as local schools. Voluntary organisations are not commercial organisations intent on making a profit The range of movement at the joints. This is important as it reduces injury and allows for a full range of movement. It is essential in hurdling, gymnastics and swimming. The ability to lift a maximum weight in one attempt. It is essential in weight lifting. Strength Flexibility 2a) Components of Fitness Muscular Endurance The ability of the muscles to contract over a long period of time without tiring. Important in activities such as walking, running and cycling. Cardiovascular Endurance Speed The ability to move the body and limbs quickly, as in running fast or throwing a ball in cricket or rounder's. The ability of the heart to pump blood and deliver oxygen where needed in the body. Important in continuous activities such as long distance running. The ability to change direction quickly e.g. skiing. Simple – reacting to a signal e.g. sprint start gun. Putting actions involving the limbs and the whole body together e.g. pole vault. Agility Coordination Reaction Time 2a) Components of Fitness Static – holding a position without movement Balance Dynamic – maintaining a position when moving e.g. surfing Choice – responding to a variety of signals e.g. playing a cricket shot. Timing The ability to perform an action or movement at the exact time e.g. playing a cricket stroke. Food is the body’s source of energy. Diet is important, not only to maintain healthy body systems, but also to provide energy for exercise. It is important to have a balance of all 7 types of foods. Eating the correct quantities and combinations will keep the body systems functioning properly, keep hair and skin in good condition and reduce the chances of obesity. 2b) Factors Affecting Fitness - Diet Provides Energy Food does the following Contributes to Good General Health Repairs Injured Tissue Helps our Body Grow Simple – sugars e.g. jams, honey, chocolate and milk. Complex – starches e.g. vegetables, cereals, rice, pasta and bread. They maintain our body’s energy stores. The body breaks down carbohydrates to give glucose and glycogen, the main sources of energy. Saturated – found in animal products e.g. milk, meat, cheese and butter. Energy can be provided by fats but it Is not readily available as energy from carbohydrates. Carbohydrates Proteins are made from Amino Acids and are essential in building cells, making blood and repairing muscle tissue. Polyunsaturates – found in fish and vegetables oils. Fats 2b) Factors Affecting Fitness Diet Cholesterol – found in fatty animal products. Too much cholesterol in the blood leads to clogging of the arteries, increasing blood pressure. Fats: provide energy, keep the body warm, protect vital organs. Proteins Vitamins Proteins: make tissue, bones and skin, repair damaged tissue and enable growth. Vitamins: regulate chemical reactions in the body, release energy from food, maintain resistance against disease, help with growth and repair. Trace substances found in food which are necessary for the normal functioning of the body. Examples include: calcium in milk, iron in meat, liver and green vegetables. Fibre does not contain nutrients but provides bulk for food and is essential to digestion. Helps to prevent constipation. Minerals are very small quantities of chemical substances in food. Encourages slower release of energy. Minerals Fibre 2b) Factors Affecting Fitness - Diet Makes up two thirds of the body’s content. Fluids must be replaced to prevent dehydration, especially during physical activity. Water Found in wholemeal bread, vegetables, fruit and cereals. Lost through sweating, urine and breathing. Hot weather can also increase the loss of fluids and cause dehydration. Small Amount of Body Fat Broad shoulders Narrow Hips Square Head Muscular Arms Muscular Legs Mesomorph 2b) Factors Affecting Fitness - Somatotypes Wide Hips Ectomorph Endomorph Large Head Narrow Shoulders and Hips Narrow Shoulders High Forehead Lots of Body Fat Thin Arms and Legs Fat on Arms and Legs Little Muscle, Small Amounts of Body Fat Thin Face Body Builder Weight Lifters Sprinters Rugby Player Swimmer Rugby Prop Sumo Wrestler 2b) Factors Affecting Fitness – Somatotype Associated Sports High Jumper Long Distance Runner These factors can not only affect the sport that you play but also your position within a team game. Being heavy is an advantage in games such as rugby. Weight is not as important to backs, who rely upon abilities such as speed and agility. Weight Being heavy helps forwards especially props and second rows to perform in areas of the game such as the scrum. 2b) Factors Affecting Fitness – Height and Weight Height Being tall is an advantage in activities such as the high jump and sports like basketball. Being short is an advantage in sports like horse racing and activities like gymnastics.

It is important that test follow the same procedures so that results are accurate Co-ordination 2c) Effects of Fitness on Performance Power Cardiovascular Endurance Speed Fitness Tests Agility Flexibility Reaction Time Muscular Endurance At the end of 12 minutes, the distance to the nearest 100 metres is recorded Run or walk laps of the 400m metre track for 12 minutes This test cardiovascular endurance 2c) Effect of Fitness on Performance – Cardiovascular Endurance 1) Instructions are given at the start of the CD which also signals when to change pace 2) The pace must be judged so the person puts on foot over the line as the beep sounds This test cardiovascular endurance 3) This is repeated a number of times and then the time between the beeps is shortened requiring a quicker pace 4) When the person can no longer keep up with the beeps / pace they drop pout and record the level they achieved 1) After a suitable warm up, the subject lies face down in the direction they will run 2) After the starting signal they should run the route shown to the left as fast as possible Illinois Run (measures agility) 2c) Effects of Fitness on Performance – Speed and Agility Speed The time taken to do a short sprint between 30 – 50 metres is taken with a stop watch. There needs to be a moving start, otherwise reaction time, explosive strength and sprint start technique become significant factors. Distances longer than 50 metres might involve elements of muscular endurance. This measures flexibility at the hip joint, which is generally restricted in movement by the hamstrings 2) The bare feet are placed against the edge of the box and the back of the legs in contact with the floor 1) Subject needs to warm up first Sit and Reach (Flexibility) 3) The subject reaches slowly along the bench with both hands, fingers outstretched as far as possible and this distance is recorded 2c) Effects of Fitness on Performance – Flexibility and Balance Stork Stand (Balance) 1) Stand on both feet, hands on hips, the non-balance leg is lifted so that the toes are placed against the preferred balance leg, the weight is then taken on the ball of the foot and the length of the time this is held is taken 2) The test is finished when the non balance foot is placed back onto the floor, the time the balance was held is recorded Press Up Test 2c) Effects of Fitness on Performance – Muscular Endurance Sit Up Test 2c) Effects of Fitness on Performance – Co-ordination, Reaction Time and Power 2d) Fitness Training Principles – Personal Exercise Programme / Warm up & Cool Down 2d) Fitness Training Principles – S.P.O.R.T 2d) Fitness Training Principles – F.I.T.T 2e) Training Methods – Circuit / Fartlek / Interval Training 2e) Training Methods – Weight / Continuous / Flexibility Training Greater Supply of Blood Sent Around the Body to Working Muscles Circulatory Rate Increases Greater Intake of Oxygen to Meet Demand From Working Muscles Breathing Rate Increases Circulation Remove More Carbon Dioxide Respiration 2f) Training Effects – Short Term Effects Pulse Rate Increases Muscles Pulse Rate Sweating Heart Pumps Blood Containing Oxygen to Working Muscles Stroke Volume Increases Body Temperature Increases The Body Sweats to Cool the Body Down Muscles Ache Lactic Acid Build Up The extent of the increase in muscle mass is influenced by the type of training that is undertaken Rate of recovery speeds up as body can repay oxygen debt more efficiently Reduction in body fat and an increase in muscle mass Body Composition Rate of Recovery 2f) Training Effects – Long Term Effects Greater levels of selfesteem and confidence Nervous System Sleeping patterns become more regular Reaction times are faster Alertness levels improve Concentration enhanced Resting heart rate is lower Heart rate increases more slowly as exercise begins Quicker heart rate recovery Stroke volume increases Greater cardiac output Circulatory System Hear becomes bigger with thicker walls (hypertrophy) More red blood cells 2f) Training Effects – Long Term Effects Respiratory System Diffusion in the lungs increases Greater VO2 max More alveoli in the lungs Can cope better with lactic acid Lungs have a greater vital capacity as diaphragm and intercostal muscles get stronger Tendons Become Stronger Ligaments Become More Flexible Calcium Added to Bone Tissue Strengthening the Bones Cartilage Becomes Thicker Skeleton 2f) Training Effects – Long Term Effects Increase in Muscle Mitochondria ‘Powerhouse’ Sites Where Most of the Energy for Muscle Movement is Produced Muscular System Muscle Hypertrophy Muscles Become Bigger and Stronger Improved Muscular Flexibility Increase in Muscle Myoglobin Absorbs Oxygen From the Blood and Takes it to the Mitochondria in the Muscle
