The truth about sports drinks

Sports drinks are increasingly regarded as an essential adjunct for anyone doing exercise, but the evidence for this view is lacking. Deborah Cohen investigates the links between the sports drinks industry and academia that have helped market the science of hydration

Prehydrate; drink ahead of thirst; train your gut to tolerate more
fluid; your brain doesn’t know you’re thirsty—the public and
athletes alike are bombarded with messages about what they
should drink, and when, during exercise. But these drinking
dogmas are relatively new. In the 1970s, marathon runners were
discouraged from drinking fluids for fear that it would slow
them down,says Professor Tim Noakes, Discovery health chair
of exercise and sports science at Cape Town University. At the
first New York marathon in 1970, there was little discussion
about the role of hydration—it was thought to have little
scientific value.
