Intrinsic and Extrinsic Motives Support Adults’ Regular Physical Activity Maintenance

[摘要] Motives for physical activity were compared between adults who either successfully or unsuccessfully maintained regular physical activity over the last 10 years. Adults age 28–45 (N=721) completed an online survey, reporting their current physical activity levels and self-determination theory (SDT) motives, as well as their physical activity levels at least 10 years prior. With participants’ current and retrospective reports of their physical activity, four sample subgroups were created, including maintainers, improvers, decliners, and sedentary.
