Rehydration study shows water still best choice

A Griffith Universitystudy has found that once food is consumed, water should be the drink of choice for most of us following a workout.

Ten endurance trained athletes aged between 18 and 30 cycled intensively for one hour on four separate occasions as a part of the small study that has been published in the peer-reviewed scientific journal Physiology and Behaviour.

Participants were provided with one beverage to drink as they desired following the exercise. The beverages included water (used on two of the trials), a carbohydrate-electrolyte (sports drink) Powerade or the milk-based drink Sustagen Sport.

In addition, on two occasions during recovery, the participants were given access to a variety of food which could also be voluntarily consumed.

“The fluid provided from all beverages was equally well retained, despite different consumption volumes, and resulted in participants’ body weights returning to near pre-exercise levels,” said Associate Professor Ben Desbrow from Griffith’s Menzies Health Institute Queensland.

“The findings from this study demonstrate that the consumption of food following exercise plays an important role in causing fluid retention when different beverages are consumed. The take home message was that when participants consumed a fluid containing calories (i.e. the Powerade or Sustagen Sport trials), their combined energy intake from the drink and food was greater than on the water trials.”

Associate Professor Desbrow said it was imperative, when making post-exercise nutrition recommendations, to consider beverage selection within the context of an individual’s broader health targets.

“For those with a weight loss goal, a calorie-free drink such as water is the perfect choice,” he said.

 “It rehydrates equally effectively as other beverages, without supplying additional energy.”
