In his words, competition groups “frame relationships in terms of goal-setting by the most active members. These relationships help to motivate exercise because they give people higher expectations for their own levels of performance.”
The researchers tracked 800 students who signed up for an 11-week exercise program. Those who attended the most exercise classes won a prize.
Participants were divided into four groups: individual competition, team support and team competition through social media, or a “control group” that had no social media competition or support.
The researchers found attendance to be 90 percent higher in competition groups than control groups.
Centola added, “Most people think that when it comes to social media, more is better. This study shows that isn’t true: When social media is used the wrong way, adding social support to an online health program can backfire and make people less likely to choose healthy behaviors. However, when done right, we found that social media can increase people’s fitness dramatically.”
The researchers suggest that friendly competition can expand beyond just exercise and be extended to improve smoking cessation and medication adherence, too.
Centola concluded, “Social media is a powerful tool because it can give people new kinds of social influences right in their own home. Lifestyle changes are hard to make, but if you can give people the right kinds of social tools to help them do it, there’s a lot of good that can be done at relatively little cost.”
