Milk better than water to rehydrate kids, study finds

Summary:
Children become dehydrated during exercise, and it's important they get enough fluids, particularly before going into a second round of a game. A new study by researchers in Canada found that milk is better than either a sports drink or water because it is a source of high quality protein, carbohydrates, calcium and electrolytes.

Active children need to be watered with milk. It's a more effective way of countering dehydration than a sports drink or water itself, say researchers at McMaster University.

That's particularly important during hot summer weather, says Brian Timmons, research director of the Child Health and Exercise Medicine Program at McMaster and principal investigator of the study.

"Children become dehydrated during exercise, and it's important they get enough fluids, particularly before going into a second round of a game. Milk is better than either a sports drink or water because it is a source of high quality protein, carbohydrates, calcium and electrolytes."

He added that milk replaces sodium lost in sweat and helps the body retain fluid better. As well, the milk provides protein needed by children for muscle development and growth which is not found in the other drinks.

The study of eight to 10-year-olds involved exercising in a climate chamber, then receiving a drink and being measured for hydration.

Timmons, an assistant professor of pediatrics of the Michael G. DeGroote School of Medicine, said active children and adults usually don't drink enough to stay hydrated during exercise, so they often have a "hydration disadvantage" when they start their next period of exercise.

He said that one per cent dehydration can have up to a 15 per cent decrease in performance, with an increased heart rate, core temperature and less ability to keep going. More significant dehydration comes with an increased risk of heat-related illness such as heat stroke.

Timmons' graduate student Kim Volterman will be presenting the research at the European Group of Pediatric Work Physiology XXVII Biennial Conference, being held Sept. 19-23 at the University of Exeter in the UK.

The study is funded by Dairy Farmers of Canada.
