sharplyAssociated with higher risk of adulthood obesity
and associated health risks and problemsTraditional exercise programs can be effective
at improving weight loss, insulin sensitivity, and spontaneous actvity.
Overweight children are less likely to participate in these programs
Enter--------------------------> EXERGAMING
IntroductionExergaming is a video game that requires
interactive physical activityIntegrates play with exerciseTwo “exergames” were evaluated on two
different platforms – (Sony Playstation 2 and Nintendo Wii)
Has been described in lay media as potential to provide exercise stimulus
No data on physiological responseCompared to walking on treadmill
Methods23 healthy children (14 boys, 9 girls) aged 10-
13Recruited locallyTwo visits
Dance Dance Revolution on visit one Wii play and treadmill on visit two
Fasted for 4hours prior except waterConstant temperature and humidityEach visit started with a 20 minute rest phase
MethodVisit One
Rest – 20 mins DDR level one – 15mins Rest 2 minutes DDR level two – 15mins Rest – 15 mins
MethodsVisit Two
Rest – 20 mins Wii bowling – 15mins Rest 2 minutes Wii boxing – 15 mins Rest 15 mins Treadmill : 2.6 km/hr (6mins)

Results
DiscussionBoth Wii sports and DDR elicit increases in
energy expenditure, heart rate and perceived exertion.
Similar to or exceeding moderate intensity walking
Help counter the effects of sedentary behaviourImportant factor is the entertainment valueRecommend 60 mins moderate activity per day
on most days of the week – study shows DDR / Wii sports fulfills this requirement.
ConclusionsActivity promoting video games increase
energy expenditure equivalent to moderate intensity walking
Encouraged to be more physically attractiveOveruse injuries comparable to other pursuits
Small studyNeed more data on effect of body composition
