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

  25. Some of the favourites... 900 kcal 65 kcal 300 kcal 140 kcal 212 kcal 165 kcal 450 kcal 50 kcal 350 kcal 180 kcal 400 kcal 88 kcal

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

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

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

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

  30. 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

  31. Optimum Weight “Ideal weight for a person - giving them the best chance for success”

  32. 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 • Doesn’t take into consideration muscle mass and proportion of fat.

  33. Underweight = • Below 18.5 • Healthy = • 18-25 • Overweight = • 25-30 • Obese = • 30-35 • Morbidly Obese = • 40 +

  34. 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
