2 Goals Understand the basic components of nutrition Understand the requirements of an athletes nutrition during the race Understand the process and caloric intake Understand Carbo-loading

3 Sounds Familiar Entry Fee = $200 Training Plan = $300 / month New Bike = $2,500 Race Wheels = $1,500 Travel Expenses = $2,000 Having the race of your life = Priceless

4 Body Composition RMR - Estimate from The Mifflin - St. Jeor equation is the most accurate for the general equation. Convert your weight from pounds to kilograms Weight: 181 / (2.2) = Height: 72 x (2.54) = Men: RMR = [9.99 x (82.7) wt] + [6.25 x (182) ht] - [4.92 x (35) age] + 5 Women RMR = [9.99 x wt ] + [6.25 x ht] - [4.92 x age] -161

5 Metabolic Efficiency (ME) The efficiency at which the body can utilize its internal stores of carbohydrate and fat at rest and during exercise. Health ad performance goal: improve the body s ability to oxidize fat, thereby preserving carbohydrate Storage of carbohydrates: Up to 2,000 for the average male, female or much more less Storage of fat Up to 8,000 calories

6 Training and Nutrition Cycle Changes Training Calories 20 0 January March May July September November

7 Carbohydrates & Protein Fruits & Non-Starchy Vegetables The density of vitamin and mineral micronutrients in these far exceeds that of the starches and simple sugars. Protein Keep intake of lean protein high by including such food in every meal

8 Metabolic Inefficiency Poor utilization of fat stores CHO Fat Increased reliance on carbohydrate limited stores Increased need for supplemental carbohydrates Higher risk of GI distress

9 Metabolic Efficiency Aerobic Training Mitochondrial capacity enzymes Nutrition Periodization Plates

10 Training Cycles Preparatory (Base) Physical Goals Endurance Strength Flexibility Technique??? Competition (Build / Race) Physical Goals Speed Economy Skills Power??? Transition (Off-season) Physical Goals Recovery Rehab Fun???

11 Carbohydrate: Protein Ratio Recommended Rations for Training Nutrition Training Day Description Carbohydrate: Protein Ratio Recovery or Rest 1:1 Low volume (aerobic, < min) lor low intensity High volume (. 120 minutes ) or high intensity (i.e., intervals, tempo) Very heavy training day or 2 or more sessions per day 1:1 or 2:1 1:1 up to 3:1 1:1 up to 4:1

15 Before the Race Carbo Loading Myths: Night before race day, eat a pasta dinner. False, it takes hours for food to leave our bodies after we place it in our mouth. Truth, you will gain weight during this loading phase. 2-3 lbs

16 Metabolic Exchange Testing Do I need to get tested? Not really? Methods Incremental Continuous

17 Protocol Information No calories 8-12 hours (variable) Bike with power measuring capabilities Treadmill (1-2%) Submaximal exercise bout, minutes Warm up of minutes on the cart

18 Adaptation Time Metabolic efficiency can be developed in as little as 2 weeks metabolic efficiency can be lost in as little as 2 weeks Learning curve for different athletes based on daily nutrition

19 Appliction of Metabolic Efficiency Inappropriate CHO load and lack of periodized nutrition and lack of aerobic training Poor utilization of body fat sotres for energy Inability to properly feed during training / racing Increased incidence of GI distress More reliance on supplemental CHO; possible weight/fat gain Lower power/velocity

20 Carbohydrate: Protein Ratio Recommended Rations for Training Nutrition Training Day Description Carbohydrate: Protein Ratio Recovery or Rest 1:1 Low volume (aerobic, < min) lor low intensity High volume (. 120 minutes ) or high intensity (i.e., intervals, tempo) Very heavy training day or 2 or more sessions per day 1:1 or 2:1 1:1 up to 3:1 1:1 up to 4:1

21 Carbo Loading Weight: / 2.2 = (A) Consume at least 5 gram of carbohydrate per kilogram of body weight per day for the 4-7 days before the race (A) X 5 = Consume 10 grams of carbohydrate per kilogram of body weight per day for the 1-3 days before the race. (A) x 10 = Large carbohydrate meal two nights before the race and go light the night before the race.

22 During the Race or Training Sport Swim, Bike or Run Distance Olympic, Full or Half Pace

23 Hydration Assessing Hydration Status Urine Color Percent body weight change Scale Hydration Status % Body Weight Change Well hydrated + 1 to -1 Minimal dehydrated -1 to -3 Significant Dehydrated -4 to -5 Serious Dehydrated More than 5

24 Pre Race Hydration Tips Goal: begin hydrate and with normal electrolyte levels Water follows sodium. Osmotic drive to drink is maintained and urine production is suppressed. Pre-race urination, hyperhydratoin and hyponatremia Effective acclimatization requires at least 14 days for an athlete to become 95% acclimatized to hot/humid conditions It is possible to lose upwards of 1-3% of your body weight during sleep

25 During Race Fluid Tips Fluid replacement depends on sweat rate, duration and opportunities to drink It si difficult to recommend specific fluid and electrolyte intakes because of different metabolic requirements, duration, clothing, equipment, wether, acclimatization Athletes can monitor body weight changes in training

26 Post Race Fluid Tips Goal: promote optimal rehydration Replace 150% of fluid losses One pound of fluid = 16 ounces thus drinking 24 ounces of fluid per pound of body weight lost will begin rehydration process Sodium is absolutely necessary Rehydrate immediately post-race

27 Composition of Sweat Na Cl K Ca Mg Others

28 Sodium Facts Healthy or clean eating can = higher incidence of cramping. Sodium loading is effective in this case Sports drinks cannot match most athletes sweat sodium losses. Supplemental sodium is needed and sometimes necessary.

29 Hyponatremia Sings Rapid weight gain (post exercise) bloated stomach swollen hands and feet Nausea and vomiting throbbing headache dizziness confusion and disorientation

30 Causes of Hyponatremia Increased Total Body water excessive drinking and Inappropriate IV therapy Inadequate sodium intake Low sodium diet and inadequate sodium intake during exercise Reduced Urine Output Exercise and Heat exposure Large Sodium Loss High sweat rate, High sweat (sodium), Poor heat acclimatization A combination of salty sweat loss and hyotonic fluid replacement may lead to hyponatremia

31 Muscle cramping Muscle cramps are involuntary muscle spasms resulting form one or more of the following Dehydration Sodium loss Fatigue (training program) Forceful, repetitive contractions of muscles used in sports might trigger cramps (finish line sprint)

36 Calories on the Run One: Determine running calorie expenditure per mile by 0.63 x body weight (pounds);.63 x = Two: Determine goal race pace or how many miles/hour will you cover, example: An 8-minute miler will cover 7.5 miles/hour; Pace: Three: Calculate hourly expenditure based on goal race pace, example: An 8-minute miler would multiply 7.5 by the figure from step one; finally step Step 1 x Step 2 = MPH Pace 5 12: : : :14 7 8: :00 8 7: :04 9 6: : :00 Four: Determine hourly calorie replacement needs: *.20 x C (Research shows runners can physically absorb about 30% of what they expend.)
