BACKGROUND: The association between cognitive training and exercise motives remains unclear, especially when training targets self-regulatory capacity rather than goal content. PURPOSE: To explore the nature and replicability of exercise motive profiles among low-active middle-aged adults, examine how a multimodal cognitive training intervention was associated with transitions across profiles, and assess associations between motive profile membership and subsequent physical activity adherence over 12 months. METHODS: = 46.7) completed the Exercise Motivation Inventory-2 (EMI-2) at baseline and one-month post-randomization. Latent profile analyses identified motive profiles at each time point; profile similarity tests and latent transition analyses assessed replicability and change. Physical activity guideline adherence was tracked monthly for 12 months post-intervention using Fitbit-derived moderate-to-vigorous physical activity. Baseline demographics, Fitbit steps, and cardiorespiratory fitness were examined as correlates. RESULTS: Four profiles emerged and replicated over time: Weakly Motivated, Moderately Motivated with Fitness Orientation, Moderately Motivated with Psychological Well-Being Orientation, and Strongly Motivated. Membership to these profiles was not associated with demographic characteristics, and only minimally by baseline Fitbit steps and cardiorespiratory fitness. The first two profiles displayed fewer months meeting physical activity guidelines, whereas t...
