The 13-week study included 78 kids—51% of them boys—of varying ethnic backgrounds, aged 9–12, divided into an active game group and an inactive game group. Games were considered “active” if they required players to move while playing. Inactive games required no movement. Throughout the protocol, the children were instructed to keep track of the amount of time they spent playing games. They were also given accelerometers to measure their exertion levels.
Unfortunately, there was no significant difference in overall activity levels between the groups. The researchers noted that although the children in the active group played more intensely while under observation, they reduced that level when they were outside the clinical setting.
But wouldn’t the active gamers log more physical activity than the non-active group in general? The authors proposed that the lack of difference between the groups might have been due to the active children compensating for the increased gaming activity by being less active at other times of the day. The authors’ conclusion: “These results provide no reason to believe that simply acquiring an active video game under naturalistic circumstances provides a public health benefit to children.”
