  1. Playing Active Video Games Increases Energy Expenditure in Children Dr. Simon Benson GP Specialty Trainee

  2. Introduction • Prevalence of overweight children increasing sharply • Associated with higher risk of adulthood obesity and associated health risks and problems • Traditional 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

  3. Introduction • Exergaming is a video game that requires interactive physical activity • Integrates play with exercise • Two “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 response • Compared to walking on treadmill

  4. Methods • 23 healthy children (14 boys, 9 girls) aged 10-13 • Recruited locally • Two visits • Dance Dance Revolution on visit one • Wii play and treadmill on visit two • Fasted for 4hours prior except water • Constant temperature and humidity • Each visit started with a 20 minute rest phase

  5. Method • Visit One • Rest – 20 mins • DDR level one – 15mins • Rest 2 minutes • DDR level two – 15mins • Rest – 15 mins

  6. Methods • Visit Two • Rest – 20 mins • Wii bowling – 15mins • Rest 2 minutes • Wii boxing – 15 mins • Rest 15 mins • Treadmill : 2.6 km/hr (6mins) 4.2 km/hr (6mins) 5.7 km/hr (6mins)

  7. Methods • Measurements • Expired oxygen • Expired carbon dioxide • Heart Rate • Footstep Rate • Perceived Exertion • Arterial Elasticity

  8. Results ■ Boys □ Girls Treadmill high equivalent Treadmill low equivalent Rest equivalent

  9. Results

  10. Discussion • Both 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 behaviour • Important factor is the entertainment value • Recommend 60 mins moderate activity per day on most days of the week – study shows DDR / Wii sports fulfills this requirement.

  11. Conclusions • Activity promoting video games increase energy expenditure equivalent to moderate intensity walking • Encouraged to be more physically attractive • Overuse injuries comparable to other pursuits • Small study • Need more data on effect of body composition
