M&C Saatchi produced the £2.3 million campaign for Lucozade Sport Hydro Active, which marks the brand's entry into the so-called "fitness hydration" market.
The product contains fewer carbohydrates than the main Lucozade Sports brand and is targeted at athletes who want to minimise their calorie intake.
GlaxoSmithKline, the product's owner, claims the essential salts in Sport Hydro Active help replace the fluid lost during exercise. Its light fruit flavour is intended to encourage users to drink at the time they need it most.
The new ad, breaking nationally on Monday, is part of an effort to convince gym goers, particularly women, to think twice about drinking water before they exercise.
It is a response to GSK research claiming to have discovered a clear consumer need for a new type of sports drink among regular exercisers.
They are driven by the desire to keep fit and in shape but are currently mainly drinking water.
Matt Eastwood, the agency's creative director, said: "Lucozade Sport Hydro Active is the first product of its kind in the UK and so, too, is its ad-vertising. The special effects in this spot have never been done to this level before."
The film was written by Kit Dayaram, art directed by Colleen Philips and directed by Philipe Andre though Harry Nash.
MediaCom is handling media buying for the campaign, which also includes a poster and women's press initiative covering titles such as Cosmopolitan, Company, Glamour and Shape.
TV ads will run around programmes including The Salon, Friends and Jamie's Kitchen.
