Parents are fooling themselves if they hope Nintendo's Wii
active games console, which uses a wireless handheld controller to
replicate athletic movement, will stop their youngster becoming
obese, a study says.
Researchers in sport science at Liverpool John Moores University
in northwestern England recruited six boys and five girls aged
13-15 years and fitted them with a monitoring device to calculate
energy expenditure.
The teens played four games for 15 minutes. One of the four
games was Project Gotham Racing 3, played on the sedentary XBOX
350, made by Microsoft. The three other games were sports bowling,
tennis and boxing, played on Wii Sports, with a five-minute rest
between sports.
In all, the children played on the consoles for one hour.
Energy expenditure using Wii was "significantly greater" - 51
percent more - than on the XBOX, the scientists found.
But this figure alone is misleading, as the total number of
extra energy units burned using Wii amounted to only 60 calories
per hour, or about a quarter of a Mars bar.
"In a typical week of computer play for these participants,
active gaming rather than passive gaming would increase total
energy expenditure by less than 2 percent," says the study.
Even though the amount is "trivial", it might still make a
contribution to weight management, the study admits.
"Given the current prevalence of childhood overweight and
obesity, such positive behaviors should be encouraged," it
says.
Even so, nothing is a substitute for getting out of the home and
doing sport itself.
"The energy used when playing Wii Sports games was not of high
enough intensity to contribute towards the recommended daily amount
of exercise in children," the authors say.
