Degrees of being overweight OVERWEIGHT OVERFAT OBESE Heavier than average of gender, height, build. Not necessarily a threat to health – muscle? Direct effect on health High level of fat Can lead to obesity related disease High blood pressure, heart attack? Abnormally fat - 20% Health risks - diabetes, heart disease In extremes - can be fatal

Degrees of being underweight UNDERWEIGHT ANOREXIC 10% under optimum weight Some naturally underweight Others try to be underweight to help their sport Anorexia nervosa See themselves as fat so don't eat Obsessive state of mind Depression, kidney/liver damage, death Irregular periods, risk of injury, fatigue, osteoporosis

Task Look at the images below and think about the characteristics of each body type (shoulders, hips, body fat, muscles) RESEARCH: What are the 3 somatotyopes called? List at least 3 sports or sporting positions that are most suited to these body shapes.

A mesomorph body shape has the following characteristics:  Wide shoulders.  Narrow hips.  Muscular body, arms and legs.  Very little body fat. The word ‘Muscular’ will help you remember the body shape of a Mesomorph. Mesomorph

The ectomorph body shape has the following characteristics:  Narrow body.  Thin body, arms and legs.  Little body fat.  Very little muscle. The word ‘Thin’ will help you remember the body shape of an ecTomorph. Ectomorph

An endomorph body shape has the following characteristics :  Wide hips  Narrow shoulders  Fat arms and legs  Fat body The word ‘Dumpy’ will help you remember the body shape of an enDomorph. Endomorph

Why does Optimum Weight vary? Height  Tall people = greater optimum weight;  Due to higher percentage of bone. Bone Structure  Body frame (broad/ narrow) will influence weight.  Physically active children have more layers of bone, therefore increasing bone density and weight. Gender  M and F have different body fat percentages.  Average body fat: 20% M 30% F Muscle girth  Muscle weighs more than fat.

1) Optimum Weight 2) Anorexic 3) Obese 4) Overfat 5) Overweight 6) Underweight A) People who are very overfat. B) Weighing less than is normal, healthy or required. C) More bodyfat than needed. D) Ideal weight for a person. E) Prolonged weight loss eating disorder. Due to obsessive control of food intake. F) Having weight in excess of normal (not harmful unless accompanied by overfatness). MUST: Match the terms with the descriptions SHOULD: State the somatotype for each term. COULD: State the BMI category for term.
