Special Diets
![Page 28: Diet, Work, Rest Learning Objectives Explain the importance of timing when you eat in competition Understand specific diets for specific sports Develop](https://reader035.vdocument.in/reader035/viewer/2022062619/5516c2db550346f0208b596e/html5/thumbnails/28.jpg)
High ProteinSTREGTH 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
•

TASKWhy 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

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 KgHeight = 1.7m [1.7 x 1.7 = 2.89]
Therefore BMI :80 ÷ 2.89 = 27.7
