This pilot study examines the preliminary efficacy of combining a walking regimen with gamified inhibitory control training (PolyRules!), compared to walking alone, on cognitive outcomes among healthy adults (ages 18 and over). Participants (n=30) will first be asked to wear a Fitbit for one week to capture baseline activity. Participants will then be randomized to (1) walking alone regimen or (2) walking + gamified inhibitory control training for three weeks. Cognitive assessments will be conducted at enrollment and at the end of the 4-week study protocol. The primary outcome is performance changes in attention and inhibitory control [Cancellation task, Flanker task, and Rule Set task]; And working memory capacity [N-Back task, Letter-Numbers task, and Corsi task]. Engagement and adherence will be operationalized as the frequency and duration of cognitive training passively recorded on the PolyRules! app and frequency and duration of walking as monitored by Fitbit data. Qualitative indicators will also be collected via semi-structured interviews to capture participants' satisfaction, perceived benefits of- and/or barriers to engaging with the cognitive training and/or walking regimens.
This pilot study estimates the preliminary efficacy of a walking regime with or without a gamified inhibitory control training app (PolyRules!) on cognitive outcomes among healthy adults.
