25 Your diet... What would you typically eat in a day?

26 Some of the favourites kcal300 kcal 165 kcal 450 kcal 212 kcal 180 kcal 140 kcal 900 kcal 50 kcal 350 kcal400 kcal88 kcal

27 BUT would you change what you eat if you were playing in a competition?

28 The general diet for an athlete is; HIGH in CARBOHYDRATES, LOW in FAT, With a high fluid intake, including energy drinks. Special Diets

29 High Protein STREGTH EVENTS High CHO = CHO Loading DISTANCE EVENTS Increase muscle hypertrophy Decreases fat storage in body BUT Diet increases cholesterol = heart disease and obesity More CHO (complex) eaten days before event Increase glycogen stores in body = more energy Reduce fatigue, improved performance

30 TASK Why would a 1500m runner and a triple jumper have different diets? ? ?

31 Important to time food intake prior to event, so energy from food can be released and delivered to the working muscles. Blood shunting (of cardiac output): During exercise: MORE oxygen and blood gets delivered to the working muscles. Therefore, LESS blood and oxygen delivery to the digestive system. Distribution of blood changes to the demand. for example: High intensity = more blood

32 Optimum Weight Ideal weight for a person - giving them the best chance for success

33 BMI (Body Mass Index) General way of working out whether a person is correct weight for their height Widely used to identify underweight, overweight, anorexic or obese BMI = Weight ÷ (Height x Height) (kg) (m) (m) BUT Doesnt take into consideration muscle mass and proportion of fat.

34 Underweight = Below 18.5 Healthy = Overweight = Obese = Morbidly Obese = 40 +

35 TASK Must: Work out the 6 athletes BMI AND category using their information and BMI chart above. Should: Try and identify which factors will affect optimum weight using the athletes profiles. Could: Calculate your own BMI. Eg: Weight = 80 Kg Height = 1.7m [1.7 x 1.7 = 2.89] Therefore BMI :80 ÷ 2.89 = 27.7

36 Which food groups are shown below? ? ? ?

37 ? ? ? Which food groups provide us with the most energy?
