It’s the research that all recreational outdoor fitness fans have been desperate to read!


Knocking back a beer or two at the end of a hot run doesn’t compromise the body’s efforts to rehydrate.

Monitoring 16 male athletes (where do they find these volunteers?) who ran for an hour in a hot laboratory at 35 degrees Celcius, scientists gave one group free access to mineral water, and the other group 660ml of beer (just over a pint) followed by unlimited mineral water.

The researchers measured body composition, blood and serum parameters, fluid balance and urine excretion before and after exercise, and after rehydration.

“Beer intake did not adversely affect any measured parameter,” they report in the Journal of the International Society of Sports Nutrition.

“Fluid balance and urine excretion values did not differ between the rehydration strategies. After exercise and subsequent water losses, a moderate beer (regular) intake has no deleterious effects on markers of hydration in active individuals.”
