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 = 18-25 Overweight = 25-30 Obese = 30-35 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
