Hydration and Carbohydrates (Corrections)

EVERYTHING IN GREEN IS CORRECT

Need to fix everything else that is not all green. I LISTED WHICH ONES THAT NEEDS TO BE FIXED.

Questions the need to be fixed

Part 1: 2A, 2B, 2C & 3

Part 2: 2B

Hydration and Carbohydrates

Part 1: Total Calories and Grams: 2 Methods

1 A. Calculate the daily grams of:

Brian’s mass=77.20 kg

Therefore, grams of:

Carbohydrates= (12 g x 77.20) = 926.4 grams

Protein = (2.0 g x 77.20) = 154.4 grams

Fat = (2.0 g x 77.20) = 154.4 grams

1 B. Convert grams of protein, carbs, and fat to calories of each.

9 calories = 1 gram of fat

4 calories/ gram of carbohydrate

4 calories/ gram of protein

Carbohydrates= (926.4 g x 4 calories)/ 1 g = 3705.6 calories

Protein = (154.4 g x 4 calories)/ 1 g = 617.6 calories

Fat = (154.4 g x 9 calories)/ 1 g = 1389.6 calories

1 C. Add calories from protein, carbs, and fat to determine total calories.

(3705.6 cal + 617.6 cal + 1389.6 cal) = 5 712.8 cal.

2 A. Method 2. Calculate RMR for this athlete using the Cunningham Equation. See equation below.

Cunningham Equation

Kcal/d = 500 + (22 x LBM)

kcal/d = 500 + (22 x LBM)

kcal/d = 500 + (22 x 170.20 lbs) Incorrect. Needed to calculate LBM first, and then use LBM in the equation. See the LBM example on the assignment

= 4244.4 Incorrect Result

2 B. Multiply RMR result by an Activity Factor of 1.75 - 1.9 to estimate total daily calorie needs. Select one number within the range.  Again, do not use an average, as specific results will be compared in #3. 

= (4244.4 x 1.8)

= 7639.92 2B Incorrect due to 2A.

2C was incorrect . 2C is a continuation from 2B. Needed to use correct 2B result for 2C.

2 C. Distribute total calories to calories of Carbohydrate, Fat, and Protein. See recommended Calorie Distribution percentages below. Select a distribution that equals 100%. Next, convert calories of carbohydrates, protein, and fat to grams of carbohydrate, fat, and protein.

Calorie Distribution:          50 – 65% Carb        20 – 35% Fat           15 – 20% Protein

(3705.6 cal/ 5712.8 cal) x 100% = 64.9% carb Result from 1C is not to be used here.

(617.6 cal/ 5712.8 cal) x 100% = 10.8% protein

(1389.6 cal/ 5712.8 cal) x 100% = 24.3% fat

Therefore,

Carb = 65%

Fat = 24 %

Protein = 11%

Conversion of calories to grams

65% of 5712.8 cal = 37 13.32 cal of carb

= 3713.32/4 = 928.33 grams of carb

11% of 5712.8 cal = 628.41 cal of protein

= 628.41/ 4 = 157.10 grams of protein

24% of 5712.8 cal = 1371.07 cal of fat

=1371.07/ 9 = 152.34 grams of fat

3. Compare your 2 sets of results. What are the differences and similarities?

Comparison off due to incorrect 2A, 2B, 2C.

When the two sets are compared, there is a significant difference in the grams of protein, fat and carbohydrates, the current grams of protein and carbohydrate are higher than the former; before conversion, while that of fat has fallen.

Part 2:  On the Bike Nutrition (Show all Calculations and Work) 

1 A.  Using a fluid recommendation of 7 – 10 fluid ounces every 10 – 20 minutes, how much fluid should Brian consume during his ride?  Provide a range (in ounces) and explain your answer.

Time = 3 hours= 180 min

(180 min/ 10 min) x 7 ounce = 126 ounces to (180 min/ 20 min) x 10 ounce = 90 ounces.

Brian can decide to take fluid at intervals of 10 minutes or 20 minutes during the ride; taking fluids after 10 min would be more efficient for him because the fluid consumption will be higher the better for him.

1 B. Does Brian need to stop at the remote water fountain to fill his water bottles?  If so, how many ounces does he need?  Explain your answer.

Yes. In case he consumed the fluids in the two bottles at intervals of 10 min, then he will need 78 ounces or rather in case his consumption was at intervals of 20 min then he will need 42 ounces. This is because the two bottles can only carry 48 ounces.

2 A. Using a carbohydrate intake recommendation of 30 – 60 grams per hour during his ride, calculate how many grams of carbohydrate Brian should consume during his ride.                                               

He should consume between (30 g x 3) = 90 g to (60 g x 3) = 180 g.

2 B. In addition to the one water bottle (24 oz) of Gatorade, does Brian need to carry an additional form of carbohydrate?  If so, how many additional grams does he need?  What would you specifically recommend?  Include the carbohydrate content of your recommendation.

Thus, these 3 questions were not answered (-7)

Yes, Gatorade contains carbohydrates, but not enough (only 42 grams in 24 oz).

No, there is no much need for an additional carbohydrate for him, since the Gatorade contains sucrose, which is a heavier form of carbohydrate and electrolytes like sodium and potassium which are vital for him during the activity. Moreover, there will be access to much fluids and food after the strenuous event, he can only decide to take much water for cooling down his body temperature since it is essential to consume much water for good health (Kachhawa & Baghel, 2017).
