Drinking carbonated beverages following exercise may not be a good idea. The problem is not that carbonated beverages are bad for you, but that they negatively affect "drink acceptability" and voluntary fluid intake. Fifty-two adults participated in a 30 minutes of aerobic activity two-four times a week. Five drinks were prepared one with no carbonation and the others having increasingly higher levels of carbonation, and provided to the subjects following each exercise session. The amount of fluids voluntarily taken in was monitored for 15 minutes after the workouts. After drinking the beverages, the participants evaluated them on the basis of factors such as throatburn, filling sensation. Sweetness, and thirst quenching (all come under the definition of drink acceptability). As a group, the exercisers drank less and were less inclined to perceive the drinks as palatable at the two highest levels of carbonation. --- Both of which were in the range of commercially produced drinks. The conclusion was that carbonated beverages should not be the fluid replacement choice following physical activity. Doing so might limit the consumption of fluids when they are most needed.
