B. Any fluid other than water.C. A fluid with a sodium concentration that is higher than that found in blood.
D. A fluid that has more than 100 calories.

Answer 1

Answer:

The correct answer is A. hypertonic fluid with more than 8% carbohydrate.

Explanation:

Gastric emptiness can be influenced by a number of factors like CHO concentration, meal volume, intensity of exercise, volume of meal, etc.  

Hypertonic fluids and hypertonic sport drinks contain high sugar concentration so it should not be taken during exercise time because a high amount of sugar concentration in the body slows down our gastric emptying and it also slows the absorption in the intestine.

Hypertonic fluid can be taken after the exercise to increase the glycogen storage. So the correct answer is A.
