Workout Snacks: Food to Improve Your Workout Performance
What's better for high intensity exericse - water or sports drinks?
It is right to say that sports drinks do a better job of hydration than water. Dehydration during exercise is caused due to sweating in which water and body’s electrolytes are lost. During exercise sweating occurs so as to maintain the core temperature of the body. Carbohydrate stores of the body are also depleted during exercise as the muscles use the glycogen stored in them as well as that of the liver.
Sports drinks are made up of water, salt, electrolytes, glucose or glucose polymers and fructose. Glucose and salt increase the absorbability or uptake of water in the body. The absorption of plain water as compared to the sports drinks is less and therefore, sports drinks improve hydration.
There are two main factors which affect the uptake of a drink or fluid in the body
- The speed at which it is emptied from the stomach
- The rate at which it is absorbed through the walls of the small intestine.
Glucose in the drink will prevent blood glucose levels to fall too low and also help to maintain body’s glycogen stores. Sodium and potassium are the main electrolytes which help maintain the hydration and reduce urine output.
