文摘

We conduct an 11-week online social network-based exercise program. We compare the causal effects of social support and social comparison. Social support in online networks was ineffective for increasing physical activity. Social comparison was more effective for increasing physical activity. Social comparison effects did not depend on individual or team incentives.
