Play Away the Calories, taking place at the Science Museum's Dana Centre on Wednesday 26 March, will allow visitors a special preview of the new 'Wii Fit' (due to launch across Europe on 25 April) to ascertain if modern, interactive technology could really increase fitness levels.

Visitors will have the opportunity to try out 'Wii Fit' for themselves and watch as its effectiveness is put to the test in a series of live tests. Human guinea pigs will be put through their paces, testing out Wii Fit and playing a more sedentary game, whilst measurements of their heart rate and oxygen consumption are taken to calculate how much energy is burnt.

Throughout the evening sport scientists, physiologists and games experts will be on hand to engage and discuss whether gaming can promote a healthy lifestyle. Epidemiologist Andy Jones from the University of East Anglia will examine how and why adult obesity has quadrupled in the last 25 years and will look at the role technology has played in creating a more sedentary life.

Play Away the Calories takes place at the Science Museum's Dana Centre in London on 26 March, 19:00-21:00. All events are free. The centre is open to over 18s only.
