"I Do What I Like": 8- to 10-Year-Old Children's Physical Activity Behavior Is Already Interrelated With Their Automatic Affective Processes.

The majority of middle-age children do not meet current physical activity guidelines. There is growing evidence that adults' physical activity is partially influenced by automatic affective processes, which are derived from affective experiences with physical activity. However, little is known about whether these processes are interrelated with children's physical activity level. A prospective design was used to examine whether automatic affective processes assessed by an evaluative priming procedure predict physical activity of children. Physical activity of 48 children (8.71 ± 0.71 years; 65% girls) was measured for 1 week with activity trackers. In a linear regression model, automatic affective processes (β = 0.36) significantly predicted physical activity, accounting for 11.02% of variance. These results indicate that physical-activity-related automatic affective processes are associated with children's physical activity, as has previously been found in adults. This study emphasizes the importance of fostering positive affective experiences associated with physical activity during childhood.
