Physical activity (PA) and mindfulness are independently associated with improved cognitive function; however, the effects of their combination on cognitive function are unknown. The purpose of this study was to examine the effects of an acute bout of PA, mindfulness training, and combined PA and mindfulness training on changes in cognitive function and perceived cognitive ability. Using a repeated measures within-subjects design, adults (N = 29, M age = 28.6) completed three 20-minute counterbalanced conditions: a) mindfulness training (MIND); b) moderate-intensity walking (PA), and c) moderate-intensity walking while listening to PA-specific mindfulness training (PAMIND). Participants completed the NIH Toolbox Cognitive Battery and PROMIS Applied Cognition Short Form before and after each condition. Within-subjects repeated measures ANOVAs revealed inhibitory control, working memory, task shifting, processing speed and the fluid composite score ( P < .01 for all) improved from pre-to post-condition for all conditions. Perceived cognitive ability declined across all conditions pre- to post-condition ( P < .001); decreases were largest in the MIND condition. Cognitive performance improved following acute bouts of general mindfulness, PA, and the combination of the two, but perceived cognitive ability declined. Future work is warranted to examine effects in other populations and as a result of different PA and mindfulness doses and interventions.
