The best hydration drink is one that does not shut off the osmotic drive (the drive to drink) and that minimizes urine output. Clinical trials on cyclists have shown that we’ll drink more if:
- The drink tastes good
- Doesn’t upset the stomach (isn’t too concentrated)
- Replenishes lost sodium, and
- Provides energy to muscles in the form of carbohydrates (about 6 to 8 percent solution is optimal)
To find the concentration of a drink, take the number of carb grams
per serving (times the number of servings in bottle, if more than one serving), multiply it by .035 and divide by the number of ounces the bottle holds.
per serving (times the number of servings in bottle, if more than one serving), multiply it by .035 and divide by the number of ounces the bottle holds.
Example:
25 grams (total carbs on label) x .035 / 16 ounces (fluid in bottle) = .055 or 5.5 % solution
