Motivational and implicit processes contribute to incidental physical activity.

Findings showed that elements from self-determination theory and dual process models relate to incidental physical activity behaviour. Specifically, autonomous motivation and certain implicit processes contributed to incidental physical activity engagement. This study provides an important first step towards understanding the psychological mechanisms that contribute to incidental physical activity. Statement of contribution What is already known on this subject? Motivation and implicit processes individually contribute to incidental physical activity behaviour. Autonomous motivation, rather than controlled motivation, primarily contributes to physical activity behaviour. What does this study add? Motivational and implicit processes together contribute to predicting levels of incidental physical activity. Both autonomous and controlled motivation contribute to levels of incidental physical activity. Certain implicit processes also play a role in incidental physical activity engagement.
