A study in the Journal of Sport and Health Science showed that preschoolers who engaged in exergaming, or played video games with a physical activity component, had increased moderate-to-vigorous physical activity at school after eight weeks compared with those who played outside during recess. The findings also showed increased but not significantly different motor skills and confidence among those in the exergaming group, and exergaming activity was higher among boys than girls. Definitely not a substitute for getting out and playing, but might be a way to keep kids busy in the cold weather.
