HSC07 Scheme of Work V1 A Level Health & Social Care/Schemes of work/Version 1.0 Unit Title HSC07: Food and Fitness (Optional) This unit aims to develop your knowledge and understanding of food components and balanced diets required to meet the dietary and nutritional needs of different client groups and a range of different aspects of exercise which help maintain the fitness, health and well-being of individuals. Method of assessment – a written examination of two hours Topic Learning objectives/understanding 3.7.1 Exerciserelated fitness and nutrients in food. You need to have a broad understanding of the main components of food and their functions in contributing to fitness, health and well-being. You should understand that there are many different kinds of exercise-related fitness which enable the human body to function to maximum physical efficiency. Key terms/definitions/notes Main components of food. Suggested activities Resources R Smithson AQA A2 Health Pgs 78-86 – exercise related fitness. Functions of these components. Main components of food to include carbohydrates, fats and protein. Exercise related fitness http://www.netdoctor.co.uk/focus/nut rition/ You should understand: aerobic fitness as the ability to endure or sustain work for long periods (generally any activity under twelve minutes is not fully aerobic); you http://www.nutrition.org.uk/ Aerobic fitness Get students to write types of aerobic fitness they have encountered. 1 Examining Food and Nutrition for GCSE by Jenny Ridgwell HSC07 Scheme of Work V1 should know that aerobic fitness requires effective external respiration, oxygen transport from lungs to cells and oxygen use within the cell; the measurement of aerobic fitness (VO2 max) should also be known, and the typical difference in this measurement between males and females; the short-term and long-term physiological effects of regular exercise and training on aerobic fitness should be known use of/metabolism of carbohydrates for energy (classified into sugars, starches and non-starch polysaccharides (NSP); functions should include energy supply and the effects of NSP on the digestive tract; fibre in soluble forms and the probable link to lowering blood cholesterol) use of/metabolism of fats for energy (i.e. saturated, monounsaturated and polyunsaturated; fats and oils as energy sources, for Carbohydrates Produce a fact sheet on each main food component Fats 2 HSC07 Scheme of Work V1 insulation against heat loss and for use in protective layers; you should also know that cholesterol is a fat-like substance with both useful and harmful effects) Proteins use of/metabolism of proteins for energy (composed of amino acids, some of which can be synthesised and some of which must be taken in the diet. Protein function including growth, repair and maintenance of the body and as hormones and antibodies) Muscular fitness muscular fitness, i.e. strength and stamina tocope with the stresses of everyday life. Strength should be understood in terms of both maximumstrength and dynamic strength (power). Mobility should also be understood as the ability to move with speed, balance and/or endurance. Flexibility is defined as the range of movement possible by the whole body or part of the body around a single joint. 3 HSC07 Scheme of Work V1 3.7.2 Minerals, vitamins and the consequence of deficiency on the body. 3.7.3 Physical, social and psychological benefits of regular exercise Minerals: the functions, requirements and main sources of iron, calcium, phosphorus, iodine and zinc and the effects of deficiency of these Vitamins: the functions, requirements and main sources of vitamins, including fat-soluble A, D, E and K and watersoluble B1 (thiamine), B2 (riboflavin), B3 (niacin), B9 (folic acid), B12 (cobalamin) and C (ascorbic acid) and the effects of deficiency of these. You should know the following different benefits: controlling stress by using exercise to reduce blood pressure, improve concentration span, improve decision-making, and improve sleeping pattern and lower anxiety; exercise may also help prevent indigestion, palpitations and ‘muscular’ aches and pains Minerals to include: Iron Calcium Phosphorus Iodine Zinc http://www.netdoctor.co.uk/focus/nut rition/ http://www.nutrition.org.uk/ Examining Food and Nutrition for GCSE by Jenny Ridgwell Vitamins to include: A D E K B1, B2, B3, B9, B12 C Benefits of exercise Controlling stress 4 R Smithson AQA A2 Health Pgs 101-104 HSC07 Scheme of Work V1 raising self-esteem by promoting positive mental attitude and developing selfconfidence and the ‘feel good’ factor;. you will need to have a basic understanding that these changes are linked to chemical production in the body Raising self-esteem combating ageing by maintaining body system effectiveness, i.e. respiratory, circulatory, digestive and musculo-skeletal; you should also appreciate that many age-related diseases and disorders can be reduced or prevented by regular exercise, e.g. thrombosis, atherosclerosis and osteoporosis Combating ageing balanced diet and weight control: i.e. the effects of exercise on appetite, the energy equation and the food groups associated with powering exercise; including the principles of maintaining a balanced diet including: adequate amounts of Balanced diet and weight control 5 HSC07 Scheme of Work V1 3.7.4 Exercise for disease prevention and regulation nutrients; the dangers of excesses/deficiencies; the importance of variety in a balanced diet social benefits, i.e. exercise taken in groups and contributing to the emotional and social well-being of individuals. You should have a broad range of knowledge relating to the beneficial effects of regular exercise on major diseases and disorders. This should cover: diseases that can be prevented by regular exercise, e.g. heart diseases, cardiovascularincident (stroke), type 2 diabetes and diseasesassociated with obesity diseases that may be improved or regulated by regular exercise, e.g. type 1 diabetes, hypertension. Social benefits R Smithson AQA A2 Health Pgs 95-101 Disease prevention Regulation 6 HSC07 Scheme of Work V1 3.7.5 Exercise and food programmes for different individuals You should be able to recommend suitable exercise programmes to improve the fitness of a wide range of clients including those who wish to use exercise to: 3.7.6 Barriers to participation in regular exercise Food programmes Students could visit health fitness suites either at school or a local gym to see types of programmes available. R Smithson AQA A2 Health Pgs 113-117 control weight (food menus for those who want to lose weight and macro and micro nutrients required for individuals.) rehabilitate following illness prevent and regulate disease combat ageing You should be able to recognise common barriers to regular exercise and to suggest realistic ways to overcome them. These barriers include: Exercise programmes Barriers to exercise costs skills and fitness levels facility locations work and family commitments. 7 R Smithson AQA A2 Health Pgs 109-113 HSC07 Scheme of Work V1 3.7.7 Safety in physical activity You should be aware of the principles Safety and principles of of good practice and safety when good practice taking part in physical activity. This includes the importance of: medical checks and expert advice before starting physical activity appropriate equipment and clothing warm-up and warm-down programmes correct use of monitoring equipment drinking water to avoid dehydration and as: an aid to digestion; an essential for chemical reactions; a lubricant for joints and cells and for helping regulate body temperature. The physiological basis of each of these should be known, as should the physiological consequences of failing to follow these practices. 8 Students could visit health fitness suites either at school or a local gym to look at safety. R Smithson AQA A2 Health Pgs 105-109 HSC07 Scheme of Work V1 3.7.8 Standard monitoring methods and tables You should be able to understand, recognise and use the following tables and measures: Use of tables and monitoring methods standard height and weight charts, BMI measurements and tables resting pulse rates and recovery pulse timings lung function tests, e.g. spirometry for tidal volume, minute ventilation and peak flow perceived exertion scales, e.g. Borg You should be able to identify the strengths and limitations of these different measures. 9 Students could use R Smithson the measurements for AQA A2 Health themselves or as a Pgs 86-95 class take measurements in order to understand them HSC07 Scheme of Work V1 3.7.9 Control Mechanisms You will need to know how pulse, body temperature, blood pressure and lung function are controlled. This will include the role of the nervous system and understanding the role of homeostasis as the process used by the body to maintain a stable environment. This includes the principle of negative feedback. You should understand specifically how homeostatic mechanisms control: body temperature, i.e. the role of the hypothalamus and the changes that occur involving muscles and skin blood vessels when body temperature changes; heart rate, i.e. the role of the sinoatrial node (pacemaker), adrenalin and noradrenalin; respiratory rate, i.e. the role of the brain’s respiratory centre monitoring carbon dioxide levels. Control mechanisms: Pulse Body temperature Blood pressure Lung function Role of nervous system Homeostasis 10 R Smithson AQA A2 Health Pgs 279-288 A Level PE textbooks may help here. HSC07 Scheme of Work V1 3.7.10 Assessment. You will be assessed on your knowledge, understanding and skills relating to food and fitness through a written examination of two hours. There will be four compulsory structured questions which will include short-answer and free response items. These will require you to demonstrate and apply your knowledge, understanding and skills in different contexts appropriate to food and fitness. You will also be required to analyse research data, including numerical data, relating to relevant food and fitness issues and to evaluate evidence, make judgements and draw conclusions. The questions will be drawn from each of the following nine areas of the unit: exercise related fitness and nutrients in food minerals, vitamins and the consequences of deficiency on the body physical, social and psychological benefits of regular exercise standard monitoring methods and tables control mechanisms safety in physical activity barriers to participation in regular exercise exercise for disease prevention and regulation exercise and food programmes for different individuals. To gain high marks in your written examination you should ensure that: your answers show a good level of detail, depth, relevance and accuracy you apply knowledge, understanding and skills to the material presented in the questions successfully data analysis is thorough and produces clear, logical reasoning and judgements suggestions and opinions are supported by the data and the material covered in all areas of the unit conclusions are consistent with the data and level of detail. 11
