BUT would you change what you eat if you were playing in a competition?
Special Diets • The general diet for an athlete is; • HIGH in CARBOHYDRATES, • LOW in FAT, • With a high fluid intake, including energy drinks.
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
TASK ? ? Why would a 1500m runner and a triple jumper have different diets?
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
Optimum Weight “Ideal weight for a person - giving them the best chance for success”
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.
Underweight = • Below 18.5 • Healthy = • 18-25 • Overweight = • 25-30 • Obese = • 30-35 • Morbidly Obese = • 40 +
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
