Question

You are working with an endurance athlete who is a cyclist. He weighs 160 lbs and is two days away from his 100-mile race. He is currently on a 2,800 calorie diet and his carbohydrates make up 70% of his calories.

2. Using 6-10 g/kg of carbohydrates to determine carbohydrate needs, how many grams of carbohydrates do you suggest he should be consuming? Choose a range based on where he is in his cycle or stage of training. I indicated he is two days from his event. Follow the steps:

a. Convert his weight to kilogramsremember, 2.2 lbs=1 kg

b. Decide what gram range (6-10 g/kg) you want him to be in and calculate it. How many grams of carbohydrates did you decide?

b. Explain why you chose that particular value to determine grams in carbohydrates?

Answer 1

a.Given

2.2Ibs=1kg

160 Ibs=??

Cross multiply and divide

=72.7 kg (160×1÷2.2)

b.Given 6_10gm/kg

Then for 72.7 kg=??

= 436.2gm (72.7×6÷1) ,727gm (72.7×10÷1)

He should be given 436gm to 727 gm of carbohydrate a day

b.As the recommended carbohydrate intake is 225_325gm / day .Usually in a hour 30_60gm of carbohydrate is recommended during exercise or activities. Determining this value in grams gives a clear knowledge on the intake and calculation of calorie is simpler

That is nearly 1744 kcal to 2908kcal is received from his carbhohydrate  

(1gm carbohydrate =4kcal )

436×4=1744kcal and 727×4=2908kcal
