Who Needs Sports Drinks?
Scientific studies show that, under certain circumstances, consuming sports drinks (instead
of plain water) during high-intensity exercise lasting longer than one hour significantly
enhances endurance, and some evidence also indicates it enhances performance. There
is no consistent evidence that drinking sports drinks instead of plain water enhances
endurance or performance in individuals exercising less than one hour at a time and at low
to moderate intensities. Children and adult athletes exercising for more than one hour at
high-intensity (tennis, rowing, rugby, soccer, etc.) may benefit from consuming a sports drink
rather than water. However, consuming sports drinks provides no benefit over water to
endurance, performance, or exercise recovery for those exercising less than an hour. In fact,
as with all other sugary drinks containing few to no nutrients, they are only another source of
calories. Drinking sports drinks when you are doing no exercise at all is not recommended.
