Comparison of energy expenditure in adolescents when playing new generation and sedentary computer games: cross sectional study
Playing new generation active computer games uses significantly more energy than playing sedentary computer games but not as much energy as playing the sport itself. The energy used when playing active Wii Sports games was not of high enough intensity to contribute towards the recommended daily amount of exercise in children.
Predicted energy expenditure was at least 51% greater during active gaming than during sedentary gaming. This equates to an increase in energy expenditure of 250 kJ (60 kcal) an hour during active gaming compared with sedentary gaming. 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%; although this figure is trivial it might contribute to weight management. Active gaming used less energy than authentic bowling, tennis, and boxing, and the exercise was not intense enough to contribute towards the recommended amount of daily physical activity for children. Nevertheless, new generation computer games stimulated positive activity behaviours—the children were on their feet and they moved in all directions while performing basic motor control and fundamental movement skills that were not evident during seated gaming. Given the current prevalence of childhood overweight and obesity, such positive behaviours
should be encouraged.
