Dynamic Associations of Change in Physical Activity and Change in Cognitive Function: Coordinated Analyses of Four Longitudinal Studies
نویسندگان
چکیده
The present study used a coordinated analyses approach to examine the association of physical activity and cognitive change in four longitudinal studies. A series of multilevel growth models with physical activity included both as a fixed (between-person) and time-varying (within-person) predictor of four domains of cognitive function (reasoning, memory, fluency, and semantic knowledge) was used. Baseline physical activity predicted fluency, reasoning and memory in two studies. However, there was a consistent pattern of positive relationships between time-specific changes in physical activity and time-specific changes in cognition, controlling for expected linear trajectories over time, across all four studies. This pattern was most evident for the domains of reasoning and fluency.

Introduction: Transtheoretical model (TTM) is one of the models applied to assess the physical activity behavior. From critiques to this model is that the majority of the studies based on the transtheoretical model have employed cross-sectional designs so that it fails to show the dynamic nature of change. Thus, the aim of the current study was to investigate transitional shifts in Physical Act...
