A pilot study of children's physical activity levels during imagination-based mobile games.

This research looked at Biba: a suite of mobile games intended to get kids back out to playgrounds and engaging in more moderate to vigorous physical activity (MVPA). Year after year, annual national surveys report a general decline in physical activity amongst children and a corresponding increase in screen time. Further to this, time spent outside by children has been reported to be on the decline since the 1980s. Recent work has suggested that in order to 'maintain the outdoor recreation participation of children across America, park and recreation professionals may need to embrace the expanding role of technology'. This research tested Biba in precisely this regard, deploying a 20-subject within-subject experimental design that compared Biba playground gameplay with typical free play playground sessions, measuring heart rate activity in them. The outcome demonstrated that Biba playground play results in greater amounts of MVPA with a difference in heart rate that was significantly higher in the Biba play session than in the free play session t(19) = 2.41, p < 0.05.
