Exergames play key role in getting people to be more active, reveals study.
Michigan State University's Wei Peng reviewed published research of studies of these games and says that most of the AVGs provide only "light-to-moderate" intensity physical activity.
And that, she says, is not nearly as good as what she calls "real-life exercise."
"Eventually the goal is to help them get somewhat active and maybe move to real-life exercise," she said.
Of the 41 AVG studies the researchers looked at, only three of them proved to be an effective tool in increasing physical activity.
"Some people are very enthusiastic about exergames," Peng said.
"They think this will be the perfect solution to solve the problem of sedentary behavior. But it's not that easy," she said.
It's generally recommended that the average adult get 30 minutes of moderate to vigorous exercise each day. Unfortunately, most of the games that were studied provided only light activity, "so they were not meeting the recommendations," Peng said.
However, for some populations light-to-moderate activity can sometimes be enough.
"The games do have the potential to be useful especially for populations that are more suitable to light-to-moderate activity - seniors, for example," Peng said.
She said exergames also have proven to be useful when used in structured exercise programs, such as those used for rehabilitation or in senior citizen centers.
"Just giving the games to people may not be a good approach," Peng said.
"They may not use it or use it effectively. It's better if used in a structured program where there are more people participating," she added.
The study was recently published in the journal Health Education and Behavior.
