What is the best choice of beverage to give a marathon runner at the end of a long race? What is the best choice of a non-alcoholic beverage to give to a patient with hypertension?
A 46-year-old male ultra-endurance runner is planning to run the Boston Marathon. He is a well-trained runner and has had success in running half-marathons, but has been unable to complete full marathons because he complains of feeling extremely fatigued and slows down his running pace significantly from a 7-minute mile to a 15-minute mile. This male runner weighs 150 pounds and is 5'9" tall. A full marathon takes him about 5 hours to run. Using this information, please answer the following questions. 1) Based on this runner's exercise intensity and training level, what range of carbohydrates would you recommend to him for the entire day and why? (assume energy intake is adequate) 2) Based on your carbohydrate recommendation from above, please apply your recommendation and calculate the total daily amount of carbohydrates this athlete requires to sustain marathon running. Please type out your work including all conversions and remember to provide a range of carbohydrate intake. 3) Based on the total daily amount of carbohydrates that this athlete requires, please devise a one-day plan that includes instructions for timing, amount and type of carbohydrate intake before, during and after the race. You may devise a simple table to show your plan and write one or two paragraphs to explain it. See the table example below for help. Example carbohydrate plan for question #3 Time & Meal or Snack Type | Carbohydrate Type & Amount | Gram Amount of Carbohydrate 7:00 am Breakfast | 1 cup cooked oatmeal | 25 grams | 1 cup milk (8 fluid ounces) | 12 grams | 1 medium banana | 27 grams 10:00 am Mid-morning snack | 1/2 cup orange juice | 13 grams | 1 cup strawberries | 11 grams 12:00 pm Lunch | 1 cup sweetened yogurt | 26 grams | 1 apple | 19 grams | 2 slices white bread with peanut butter | 28 grams 3:00 pm Mid-afternoon snack | Sports drink (high carbohydrate) | 88 grams Total carbohydrate | | 249 grams
