Open the original (DOI 10.1186/s40798-022-00444-9)- What it measures
- The pooled effect covers acute interventions of one bout and chronic interventions of several days or weeks. The authors report that the chronic effect was stronger.
- What it does not show
- Physical activity in general, not walking alone, and not writing. The creativity measures differ across studies, and the effect is a pooled estimate across many small studies.
