1 Nutrition and lifestyle introduction Opening screen: List examples of the issues affecting youth athletics today. Click the NEXT button: What is the goal of nutrition scientists? What is the goal of sport nutrition scientists? What is a nutrient? Why is variety of food important to an athlete? Click the NEXT button: What are the functions of food? What is the role of protein? What role do carbohydrates and fats play? What nutrients are important in the regulation of metabolism? What are macronutrients? What are micronutrients? 1

2 Click the NEXT button: Click the NEXT button: What is the new frontier in athletic performance? You have now completed this module 2

3 Module 2: Fuel for ATP production Opening screen: What physiological functions does the athlete s diet support? Muscle ATP stores remain relatively constant. Why? List the three sources of fuel for each of the ATP production mechanisms. What is the difference between the power and capacity for each ATP production mechanism? You have now completed this module

4 Nutrition for high power capacity Opening screen: The body makes creatine in the Where is most of the creatine stored? How much creatine is required each day? What proportion is found in a good diet? What proportion is synthesized in the body? What is the creatine youth rate in a sample of 12 th grade students? What is the position of the American Academy of Pediatrics regarding performance-enhancing supplements? In what type of exercise does creatine appear to help? Why is it pointless for prepubescent youth to take any form of supplementation like creatine? What are the adverse effects of creatine? the most important recommendation? If your athletes are taking creatine, what is How does the risk of compartment syndrome increase when creatine is consumed? You have now completed this module

5 Nutrition for intermediate and long-term energy capacity Opening screen: While digestive food passes through the liver what happens? What happens when fatty acids, glucose and amino acids pass through skeletal muscle tissue. Where does the unused amino acids, amino acids and fatty acids end up? How much glucose does the brain consume? Where is glucose stored? What is the significance of the liver to the brain? When liver glycogen is used how does the liver make new glucose? How are ketone bodies formed? The brain is still short of 10g of glucose per day. Where does this supply come from? As the athlete runs at a faster and faster speed what happens to the ratio of fatty acid use versus glycogen use. List the important breathing landmarks 1

6 Glucose can be made available to the mitochondria in two ways. What are these two ways. Fatty acids can be made available to the mitochondria in two ways. What are these two ways? Click the GO button for Part 2. At what intensity does the vascular supply of fuel to the muscle cell appear to plateau? After around 60% of VO2max where do most of the fuel stores come from? What happens to the glycogen supply in the muscle cell and liver during a training session? The child needs adequate energy input for four reasons. What are these 4 reasons? What happens is the athlete is in a negative balance condition? What is the relationship between carbohydrate diet and glycogen stores? Click the GO button for Part 2: What are the diet guidelines for Carbohydrate? Protein? Fat? You have now completed this module 2

7 Nutrition for maximizing speed of the ATP production mechanism Opening Screen: The speed of the ATP production mechanism is referred to as its List the ATP production mechanism in order of their number of enzymes used. What role do vitamins and minerals play in enzymes? Give examples of where magnesium is used. Why is a diet low in calcium a problem for the athlete s performance? NADH is a derivative of what vitamin? What is a free radical? Explain how antioxidants work. What is oxidative stress? What is the ORAC score?

8 What is the problem when the athlete s diet does not include foods in their natural state? You have now completed this module

9 Nutrition for enhancing performance - supplements Opening Screen: What is a sickness response due to? What happens if homeostasis is disturbed? From the body s point of view training causes it to improve its defensive capabilities against the chronic disruption the training stress is causing to its internal environment. What is the coach s point of view? What function was the immune system initially intended to perform? What is the fight-flight response? Why did this response co-opt the immune system? What is the purpose of the sickness response? Where is cortisol released from? What does nitric oxide do? What do cytokines do? What is the point of reducing plasma iron? What is the effect of cortisol?

10 Click the NEXT button: What is muscle soreness due to? What is the purpose in inflammation? What s the point of fever, reduction in plasma iron and fatigue? Why does the athlete s body suppress activity when the athlete is overtrained? Where does glutamine come from in the body? What is glutamine used for during high stress situations? What is the role of cortisol? What is the role played by clenbuterol? Why does an athlete in heavy training lose lean body mass and fat mass? Long-term elevated cortisol is a marker for What are other markers for overtraining? What is one important issue you should consider if your athletes are using legal supplements in an effort to enhance performance? You have completed this module
