Optimum Weight GCSE PE
Learning objectives… To identify the meaning of expected and optimum weight To understand the meaning of being underweight, overweight, overfat and obese To evaluate the effect these conditions have on performance
Optimum weight… Everyone’s expected and optimum weight is slightly different… Expected weight The weight you expect them to be Optimum weight The weight at which you perform your best
Optimum weight… Your optimum weight depends on 4 things… Height The taller someone is, the larger their body – so the heavier you would expect them to be. 2) Bone structure Some people have a larger bone structure than others. The more bone you have, the higher your optimum weight will be. Muscle girth This is your measurement of the circumference of your muscles when they’re flexed. Some people naturally have more muscle than others – which means they will have a higher optimum weight. Gender Men and women naturally have different body compositions. Men usually have larger bone structure and more muscle than women, so they generally have higher optimum weights.
Match up exercise! Try your best to match up the following key words with their definitions! Underweight Obese Overfat Anorexic Overweight An eating disorder where sufferers believe they are fat and starve themselves to lose weight Having more body fat than you should Weighing more than is normal Being very overfat Weighing less than is normal, needed or healthy
Underweight or overweight? Being underweight means weighing less than is normal, needed or healthy Being overweight means weighing more than is normal Overfat means having more body fat than you should Being obese means being very overfat Anorexia is an eating disorder where sufferers think they’re fat and starve themselves to lose weight
Examples… A jockey may be underweight compared to his expected weight, but at his optimum weight for his sport – the less he weighs, the faster his horse will be able to run A boxer may be overweight compared to his expected weight, but at his optimum fighting weight Can you think of any other examples from sport where expected and optimum weight may vary? Write a paragraph in your book explaining this.
How do these conditions affect performance? Have a think with your partner about how these conditions can affect performance in sport… Overweight Overfat/obese Underweight
Overweight… Being overweight means you are carrying extra weight around. This means that you can get tired more easily, so you might not be able to do endurance sports like long distance running.
Overfat/obese… Being overfat or obese can also limit your flexibility and movement. The stress the excess weight puts on the body and the heart can make doing exercise potentially harmful. Why would exercise be harmful...? What physical changes may of occurred that could cause harm?
Underweight… Being underweight because of poor diet may mean you don’t have enough energy or muscular endurance to do physical activities for a long time. What conditions can this lead to? How would you explain anorexia? How would it effect an individual?
Anorexia… Anorexia is an eating disorder where sufferers starve themselves to lose weight. Without sufficient nutrients, they will feel extremely tired. Their muscles will start to waste away and their bones weaken. This can make doing physical activity extremely difficult.
Exam questions… Which one of the following correctly identifies four factors affecting optimum weight? Bone structure, gender, muscle girth, height Height, diet, muscle growth, body composition Bone structure, age, muscle mass, weight Body composition, muscle mass, sport played, height
Exam questions… Which one of the following statements is correct? Obese – a term meaning very overweight Overweight – a term meaning excess body fat Overfat – a term meaning weight in excess of normal Anorexic – A term meaning a prolonged eating disorder due to loss of apetite

Good explanations why and linked to somatotypes… Make a weight timeline/scale for 6 different athletes, explaining why for two contrasting individuals. Use the terms expected and optimum weight 60 kg 70kg 80kg 90kg 100kg 110kg 120kg 130kg 140kg Lebron James 113kg (17’7) Mo Farah 58kg (9’1) Chris Robshaw 110kg (17’3) Jessica Ennis Hill 57kg (9’0) Serena Williams 68kg (10’7) Wayne Rooney 79kg (12’4) Higher grades Good explanations why and linked to somatotypes… Mo Farah Distance Athlete 58kg Mo Farah is underweight compared to his expected weight but is at optimum weight because… Lebron James 113kg Lebron James is Overweight compared to his expected weight but is at optimum weight because…
