There is steep competition between channels to show sporting events. AJGIBSON EIC COPYRIGHT Opportunities in sport 4 Opportunities Many opportunities exist in sport. Becoming a performer is the obvious way, but there are also other roles: • Performer • Official • Sports leader • Coach • Volunteer AJGIBSON EIC COPYRIGHT Opportunities in sport 17 The performance pyramid The performance pyramid shows the structure of progress in sport. AJGIBSON EIC COPYRIGHT Opportunities in sport 18 PESSCL Through the Physical Education School Sport and Club Links (PESSCL) strategy, the government has invested £978 million between 2003/04 and 2007/08, with the aim of increasing the number of 5–16 year olds taking up and continuing to play sport. AJGIBSON EIC COPYRIGHT Opportunities in sport 20 Sport England Sport England launced a new strategy in June 2008, Grow Sustain Excel, which aims to help people of all ages and abilities to take part in sport in their community. AJGIBSON EIC COPYRIGHT Health, fitness and exercise 4 Definitions! The World Health Organization (WHO) defines health as: ‘a state of complete mental, physical and social well-being and not merely the absence of disease or infirmity’. Definition of fitness The ability to meet the demands of the environment and still have energy left. EXERCISE An activity requiring physical effort that helps to sustain or improve your health and fitness. AJGIBSON EIC COPYRIGHT Health, fitness and exercise 12 Effects of lack of exercise • Weight increase • Less flexibility • Become breathless sooner • Aerobic capacity is reduced • Loss of strength AJGIBSON EIC COPYRIGHT Health-related exercise 4 Health-related exercise To achieve physical well-being, a performer needs to concentrate on five areas of health-related exercise: • Cardiovascular fitness • Muscular strength • Muscular endurance • Flexibility • Body composition Do you know the definitions for the 5 health related areas???!! AJGIBSON EIC COPYRIGHT The principles of training 4 Principles of training There are several principles of training, each influencing the training of a performer in a different way. Good training takes into consideration all of the principles and their effects on the body. AJGIBSON EIC COPYRIGHT The principles of training 6 The main principles of training are: • Specificity • Progressive overload • Individual differences/needs • Rest and recovery AJGIBSON EIC COPYRIGHT The principles of training 14 The point where exercise is demanding enough to have an effect on the body is called the threshold of training. As the intensity of the exercise increases there is a greater demand for more oxygen to produce energy. AJGIBSON EIC COPYRIGHT The principles of training 15 The total amount of oxygen needed so that the body can function, is called the oxygen uptake. However, there is a limit to the amount of oxygen uptake and this is called the VO2 maximum (or ‘max’). AJGIBSON EIC COPYRIGHT The FITT principle 4 The FITT principle FITT stands for Frequency, Intensity, Time and Type. All of these principles must be taken into consideration when undertaking a training programme. AJGIBSON EIC COPYRIGHT The FITT principle 16 Reversibility Reversibility is the result of stopping or not training frequently. Just as the body will increase in strength, tone and skill with exercise, it will lose them without it. Remember, if you don’t use it, you lose it! AJGIBSON EIC COPYRIGHT Goal setting 8 GOAL SETTING Short-term goals are often set in training programmes and can act as incentives to train hard as targets can be reached quickly. Long-term goals are often the culmination of several training programmes and can possibly lead to a competition or final event. AJGIBSON EIC COPYRIGHT Goal setting 11 There are two types of sporting goals: 1. Outcome Goals, which are linked to results of performance in competition. 2. Performance Goals, which are concerned with previous performances, such as being good enough to run for the country or to be selected for the Olympics. AJGIBSON EIC COPYRIGHT Goal setting 14 Goal setting should be… Specific SMART Measurable Achievable Realistic Timebound AJGIBSON EIC COPYRIGHT Methods of training 4 Methods of training Each of the following methods of training work the body differently: • Interval training • Weight training • Cross training • Fartlek training • Circuit training • Continuous training AJGIBSON EIC COPYRIGHT Recovery rates 9 Target zones and training thresholds A target zone is the range within which a performer needs to work for aerobic training to take place. AJGIBSON EIC COPYRIGHT Recovery rates 11 A training threshold is the point that must be exceeded before an effect or result can be produced. AJGIBSON EIC COPYRIGHT Recovery rates 7 Rest and recovery gives time for restoration of: • Energy-producing enzymes in muscle fibres • Stores of carbohydrates in muscle cells • Hormonal balance and immune system AJGIBSON EIC COPYRIGHT The exercise session 4 Exercise sessions An exercise session consists of three parts: 1. Warm-up: preparing the body for work. 2. The main activity: the activity, match or competition. 3. Cool-down: preparing the body to return to rest.

AJGIBSON EIC COPYRIGHT Diet 5 Balanced diet A balanced diet is made up of seven different categories: 1. Carbohydrates 5. Minerals 2. Proteins 6. Fibre 3. Fats 7. Water 4. Vitamins Can you give examples of each and what each one does???? AJGIBSON EIC COPYRIGHT Diet timing 7 Carbohydrate loading By eating more carbohydrates, a store of glycogen is built up in the body. In competition this store will reduce levels of fatigue and so help to maintain a standard of performance. AJGIBSON EIC COPYRIGHT Diet timing 13 High-protein diets High-protein diets often require a sportsperson to have smaller meals more often; six to eight meals in a day is common. The meals are usually smaller and higher in protein to aid the body’s digestion and avoid the storage of excess energy drawn from food. Smaller meals are broken down quicker and allow the body to use the protein to repair and fuel itself more efficiently. AJGIBSON EIC COPYRIGHT Planning an athletes diet • Week before………………. • 3 days before • Morning before • During competition • After competition • Explain what you would recommend to your athlete at these times AJGIBSON EIC COPYRIGHT Somatotypes 9 There are very few people with the extreme examples of these body type. Most people have a combination of all three. Sportspeople generally have more mesomorphic (muscle) and ectomorphic (thinness) than endomorphic (fatness) characteristics. AJGIBSON EIC COPYRIGHT Alcohol and smoking 6 Alcohol Alcohol can be a sedative, meaning reactions will be slower and judgement can be impaired. It masks pain, which can lead to increased injury. AJGIBSON EIC COPYRIGHT Alcohol and smoking 14 Nicotine (the drug in cigarettes) affects the body by stimulating the brain to release noradrenaline, which usually happens in times of stress. Smoking is bad for you because it: • Raises your pulse rate and your blood pressure • Shrinks your veins AJGIBSON EIC COPYRIGHT Drugs/Doping in sport • Narcotics analgesics • Diuretics • Peptide hormones • Masking agents • Stimulants • Anabolic Steroids • Beta blockers AJGIBSON EIC COPYRIGHT The heart 12 Aorta Superior vena cava Pulmonary artery Pulmonary veins Left atrium Semi-lunar valve Right atrium Mitral value Tricuspid value Left ventricle Septum Right ventricle AJGIBSON EIC COPYRIGHT Blood vessels 8 The blood vessels There are three main types of blood vessel: • Arteries • Veins • Capillaries •You must be able to describe the differences between each AJGIBSON EIC COPYRIGHT Blood 5 In adults, red blood cells(erythrocytes) are produced in the bone marrow of long bones. During exercise the blood increases in thickness as water is removed as waste . In these cells is haemoglobin. Oxygen chemically attaches itself to it to make oxyhaemoglobin. White blood cells (leukocytes) protect the body by fighting infection at its source, repairing damaged tissue after an injury and destroying bacteria. Platelets are small parts of larger cells. Platelets clump together and clot at the skin surface after a graze or cut. Plasma is mostly made up of water. It makes up 55 per cent of the volume of blood and helps the blood flow easier by the use of plasma proteins. AJGIBSON EIC COPYRIGHT Blood 18 The total volume of blood pumped out of the heart, calculated over a minute, is called the cardiac output. To work out the cardiac output, multiply the stroke volume by the heart rate: cardiac output = stroke volume x heart rate AJGIBSON EIC COPYRIGHT Blood 20 The heart rate usually needs to be raised to at least 60 per cent of the maximum to improve cardiovascular fitness levels. To work out the maximum heart (or pulse rate) the following formula is used: 220 – age = maximum heart rate AJGIBSON EIC COPYRIGHT Effects of exercise on the cardiovascular system 11 Short-term effects of exercise on the cardiovascular system Oxygen and haemoglobin combine to form oxyhaemoglobin Heart rate increases Blood vessels dilate at the skin’s surface to release heat, causing skin to redden Blood is pumped to the working muscles AJGIBSON EIC COPYRIGHT Stroke volume increases Effects of exercise on the cardiovascular system 14 Long-term effects of exercise on the cardiovascular system Develops a stronger heart Reduced risk of coronary artery disease Can cope with increased physical stress more effectively Can deliver oxygen to the working muscles more effectively AJGIBSON EIC COPYRIGHT Effects of exercise on the cardiovascular system 16 Strange heart beats! Tachycardia is a resting heart rate of more than 100 beats per minute. Bradycardia is defined as a heart rate of less than 60 beats per minute. An ECG (electrocardiogram) machine will show you what your heart rate looks like. AJGIBSON EIC COPYRIGHT Muscles and exercise 4 Muscular training Muscular endurance is the ability to keep working over a long period of time without tiring and is used in events such as long-distance running, cycling and swimming. Muscle strength can be defined as a maximum weight lifted or moved in one try. When muscles increase in size, this is called hypertrophy. If training stops then muscles lose their size, and the muscle is said to atrophy. AJGIBSON EIC COPYRIGHT Mechanisms of breathing 17 Parts of the respiratory system Can you label all these parts?? AJGIBSON EIC COPYRIGHT Muscle types 11 Muscles and their functions Trapezius – adduct at the shoulder Deltoid – abduct at the shoulder Triceps – extend at the elbow Biceps – flex at the elbow Pectorals – adducts at the shoulder Abdominals – flex at the hip Latissimus dorsi – adduct at the arm Quadriceps – extend at the knee Gluteus maximus – extend at the hip Hamstrings – flex at the knee Gastrocnemius – extend at the ankle AJGIBSON EIC COPYRIGHT Muscle types 4 Muscle types There are three kinds of muscle: 1. Voluntary muscles 2. Involuntary muscles 3. Cardiac muscles AJGIBSON EIC COPYRIGHT Muscular functions 5 The pulling muscle is called the prime mover (or agonist). The muscle relaxing is called the antagonist. When a muscle contracts it becomes shorter. When a muscle relaxes it becomes longer. ?Describe Isometric & Isotonic movements?
