2. WHAT ARE YOU PUTTING IN YOUR TANK?

3. OBJECTIVES Come away with good ideas Evaluate what you are currently putting into your body Not bore you with high level science – but still provide factual information regarding nutrition and how it relates to athletic performance Hit a few different areas besides nutrition (athletic success is a puzzle with many parts) Answer any questions you might have

4. What Influences Athletic Ability? Genetics Optimal Training Optimal Training Good Nutrition Good Nutrition No “secret” ingredient!

5. Performance Nutrition Means… Fueling to boost activity performance on a daily basisFueling to boost activity performance on a daily basis Fueling to decrease the risk of injuries, recover fully after workouts and stay healthyFueling to decrease the risk of injuries, recover fully after workouts and stay healthy Fueling with foods that taste good, foods you enjoy, foods that can be prepared easily, and foods you feel confident eatingFueling with foods that taste good, foods you enjoy, foods that can be prepared easily, and foods you feel confident eating

9. Energy Needs Basic Calorie Requirement 15-30 kcal/lbs

10. Energy Needs Calories/lbs 120lbs 160lbs 240lbs Calories/lbs 120lbs 160lbs 240lbs LOW - sedentary 1560- 1800 2080-2400 3120-3600 ACTVE (30-60min) 1920-2160 2560-1880 3840-4320 MODERATE (1-1.5hr) 2280-2520 3040-3360 4560-5040 HIGH (1.5-2hr) 2640-2880 3520-3840 5280-5760 VERY HIGH (2-3hr) 3000-3600 4000-4800 6000-7200

11. DAILY DIET 2 MOST IMPORTANT MEALS 1.) BREAKFAST Make the time to eat breakfast (pop ‐ tarts don’t count…) Quality carbohydrates for sustained energy (oatmeal) If you skip this meal it will slow down metabolism (body goes into starvation mode)

12. DAILY DIET 2 MOST IMPORTANT MEALS 2.) POST WORKOUT within 30 minutes after workout Liquid form is best Look for 4:1 Carbohydrate to Protein ratio chocolate milk is cheapest form

13. HOW MANY MEALS A DAY? 4 ‐ 6 Approximately 2 ‐ 3 hours between meals 55-65% carbohydrates 15-20% protein 20-25% fat

14. Nutrients: the body’s fuel Carbohydrates:primary fuel source Protein:used for repair & maintenance Fat:secondary fuel source Water:most essential nutrient Vitamins:colorful foods first Minerals: supplements second Fiber:20-35 grams per day

15. Digestion Time of Nutrients 4 hours 2 hours 1 hour

16. The Importance of Carbohydrates (CHO) Primary source of energy when you are exercising hard One should get at least 55-60% of calories from CHO The body stores CHO as glycogen in muscles and the liver Running out of glycogen = “Hitting the Wall”

17. Importance of CHO cont. Avg. 150 lbs man stores 1,800 Kcals of glycogen and 60-100,000 Kcals as fat Cannot use fat once you run out of CHO Trained muscles store 20-50% more glycogen than untrained muscles

18. Sample Athlete Male soccer playerMale soccer player Training 2-3 hours/dayTraining 2-3 hours/day 165 lbs = 75kg165 lbs = 75kg 9gm CHO/kg =9gm CHO/kg = 675 gm CHO 675 gm CHO

19. What does 675gm of CHO mean to an athlete? 2 large bagels 70g 2 cups cereal 90g 2 slices bread 30g 2 cups milk 25g 1 cup fruit yogurt 45g 2 cups pasta/sauce100g 1 cup beans 45g 2 pc fruit 50g 1 cup fruit juice 30g 2 starchy veggies 60g 4 cups Sport Drink 60g 20oz Soda 70g 675g

20. Protein (PRO) Needed for building and repairing muscles, red blood cells, hair and other tissues Synthesizes hormones Used for energy when CHO is not available or in exhausting exercise 15-20% of calories should come from PRO Excess protein is not stored as extra muscle, it is stored as extra FAT! Your body can only digest so much per feeding

21. CARBOHYDRATES Brown rice Sweet potatoes potatoes Oatmeal Pasta fruit PROTEIN Baked Meat Lentils Chicken Fish Dairy products GOOD FOOD CHOICES

22. Not all carbohydrate foods are created equal, in fact they behave quite differently in our bodies. The glycemic index or GI describes this difference by ranking carbohydrates according to their effect on our blood glucose levels. Choosing low GI carbs - the ones that produce only small fluctuations in our blood glucose and insulin levels - is the secret to long-term health reducing your risk of heart disease and diabetes and is the key to sustainable weight loss. What is the Glycemic Index?

25. Hydration Hydration

26. Components of Muscle 75% Water 20%Protein 5% other

27. Fluids & Hydration Fluids & Hydration Males - 60% body wt. Females - 50% body wt. Cardiovascular functionCardiovascular function ThermoregulationThermoregulation Injury preventionInjury prevention PerformancePerformance RecoveryRecovery Sweat losses during 2 hours of exercise can = 2 liters or more

28. Physiological Effects of Dehydration sweat rate blood volume & heart rate sweat rate blood volume & heart rate core body heat core body heat cardiovascular function cardiovascular function -less O2 and nutrient-rich blood to muscles -less O2 and nutrient-rich blood to muscles -more reliance on anaerobic system -more reliance on anaerobic system Slower removal of wastes cramping, fatigueSlower removal of wastes cramping, fatigue

29. Impaired Performance! Muscle strength Muscle strength Speed Speed Stamina Stamina Energy Energy Cognitive Process Cognitive Process Risk of Injury Risk of Injury 95% of muscle cramps are due to dehydration!

30. When Should You Drink? WHEN TO DRINK AMOUNT OF FLUID 2 hr before exercise 2-3+ cups 15 minutes before 1-2+ cups Every 15 minutes DURING 1-1.5 cups After Activity 2-3 cups for every lbs lost

31. What you already know… Don’t rely on thirstDon’t rely on thirst –Already 1-2% dehydrated Drink before, during & afterDrink before, during & after –2 hrs before 14-24 oz –20-36 oz/hr or 5-12 oz every 15 mins. –drink ~150% or 24oz / lbs lost Water is fine for 1 hrWater is fine for 1 hr –4-8% carb, 0.5-0.7 g Na+/L –pop, fruit juices or fruit drinks >10% may  emptying

32. Dehydration Planned rehydration is necessary  typically only 1/3 to 2/3 of the volume lost is replaced voluntarily volume lost is replaced voluntarily Hockey player average loss of 3-5%Hockey player average loss of 3-5% 1 lbs weight loss = 16 oz. of fluid1 lbs weight loss = 16 oz. of fluid –160 lbs player loses 5%  8 lbs –8 lbs  requires 128 oz of fluid to equal loss –6  20 oz sport bottles = 128oz [3.8L]

33. Nutrition MISTAKE Thinking that…. Sports drinks are only needed for exercise lasting more than an hourSports drinks are only needed for exercise lasting more than an hour –Not always true if the activity is intense & occurs in hot, humid conditions –Sports drinks actually drive thirst –Very easy way to improve performance, fight dehydration, and decrease recovery time

34. Energy Drinks? –Different from Sports Drinks –Contain caffeine, other stimulants, sugar, herbs and vitamins –Safety concerns for athletes! –Use nutrition, hydration, and lifestyle changes to improve energy level WHAT ABOUT…. 300mg caffeine!

35. Refueling after Exercise VERY Important for AthletesVERY Important for Athletes –For those in multiple events in one day –For those training daily “Window” for Refueling“Window” for Refueling –First 30 minutes after exercise is critical –Glycogen repletion occurs faster after exercise Increased blood flow to the muscle Increased blood flow to the muscle Enzymes that produce glycogen are most activeEnzymes that produce glycogen are most active

36. RECOVERY All the hard work in the weight room and in speed/agility training is worthless without recovery Your body does not become stronger and more powerful while working out but while resting RECOVERY’S 4 MAIN COMPONENTS: 1.) Nutrition 2.) Sleep (min 7 ‐ 9 hours) 3.) Rest between training sessions 4.) Choices made on weekends

37. ALCOHOL The associated residual effect of the alcoholic hangover has been shown to reduce athletic performance by 20-30% The Hangover Effect Or Disturbed Recovery Process Heavy drinking caused massive suppression of testosterone between 1.5 and 96 hours (4 days later). (Underwood/Balon 2005) You are at practice… but your hormones are not…

38. American Athletic Institute has studied the impact of alcohol on condition in elite athletes. Impact has shown significant projections in lost physiological condition that correlates to as much as 14 days of lost training effect…for each time drunk… AMERICAN ATHLETIC INSTITUTE 2005

39. STRENGTH & SPEED TRAINING No brain no gain Smarter not always harder There is no one way that is best to train Consistency is the key

40. MULTI ‐ SPORTS VS “SPECIALISTS” Take advantage of the opportunity you have and play as many sports as you can a.) exposes you to different movements / skill sets b.) different teammates c.) different coaches d.) keeps you competing and in different environments

41. Increased risk of injury due to overuse / repeated movements Increased risk of burnout In small school setting do what you can to help teams/school May miss sport they you truly enjoy or are good at (especially if “specialize at young age) MULTI ‐ SPORTS VS “SPECIALISTS”
