Sports drinks are useless for the majority of people and their use by celebrities simply misleads the public into thinking they work, experts have warned.

A host of world class sportsmen, including Real Madrid's Gareth Bale, or golf champion Tiger Woods have had sponsorship deals with sport drink manufacturers.

Although they are not as deadly as tobacco, researchers said fans and spectators may be misled into thinking these products boost sporting prowess and are good for health.

But Australian researchers said any health benefits claimed by rehydration drinks remain unproven.

Writing in the British Medical Journal, they said: "Such sponsorship could mislead the public into thinking these products work well and/or are good for health-for which there is no strong scientific evidence."

Previous research, published in BMJ Open, found a "striking lack of evidence" to support claims about improved performance and recovery for many sports products like drinks.

Experts advise that specialist sports drinks offered little benefit over plain water if you are exercising for 90 minutes or less.

At this level, the main concern is to replace fluid lost through sweat to avoid dehydration, and water does the job perfectly well.

Writing in the BMJ, Simon Outram and Bob Stewart of the Institute of Sport, Exercise, and Active Living, in Melbourne, Australia, said: "Successful sponsorship campaigns remove or minimise any scepticism about the product, a common reaction to advertising.

"A form of seamless or hidden product association is created whereby such products come to be seen as integral to sport - the sports supplement or sports drink."

Celebrity endorsement helps to promote that idea, they said.

They argued: "It is for good reason that nutritional supplement and sports drinks companies invest heavily in sports sponsorship.

"Such sponsorship - together with associated product endorsements and advertising - conveys the message that their products are integral to sporting engagement and achievement.

"Sport may have found itself lending unwarranted credibility to products which would otherwise not necessarily be seen as beneficial for participation in sports and exercise or as inherently healthy products.

"If sport authorities, teams, and sports personalities distanced themselves from supplement and drinks company sponsorship, ways would have to be found to cover the financial gap created.

"Lessons can be learnt from the history of tobacco sponsorship and its gradual restriction, which did not lead to the wholesale collapse of sport."

The World Anti-Doping Agency has also highlighted the potential inclusion of undeclared and banned substances in these products as a result of global differences in labelling and manufacture.
