1 . If sticking with an exercise habit is a challenge for you, there may be an app for that. In a University of Pennsylvania trial, smartphone games helped subjects become more active.
Participants were randomly assigned to one of three versions of a game that recorded how many steps they took each week. The first version placed them in direct competition with others. In the second version, they worked as a group to gain points. In the third, players earned points on their own but were asked to choose a friend or family member to be their supporter. This person received an e-mail each week reporting on the player's performance in order to help cheer her or him on.
On average, all three groups took more steps than usual. That said, certain versions of the game worked better for people with different personality traits. For instance, players who were more outgoing and more motivated to persevere with their goals tended to accumulate more steps in the competitive mode. In contrast, quiet players responded well to the game whether it was competitive, cooperative, or supportive. A third type, made up of those who were prone to take risks with their health and safety (by not wearing a seat belt, for example), was not helped by the game at all.
So though not all of us benefit, exercise gamification can work—and work especially well when you keep your personality in mind as you choose from among the many available apps.
