摘要：
This study seeks to examine the relationships between physical activity (PA), cognitive activity, and cognitive function for the purpose of developing future brain-fitness programs. A sample of 2,305 participants (age = 50-84, mean age: 63.1 years) was selected from the Midlife in the United States longitudinal study for analysis. The strength of the associations between the dependent variables (episodic memory and executive functions) and independent variables (three domains of PA and cognitive activity) were determined by hierarchical regression. Episodic memory regressed positively on leisure-time PA (LPA) and cognitive activity. Executive functions regressed positively on LPA and Cognitive activity, but negatively on job-related PA (JPA). The interaction effect (JPA x Cognitive activity) was nonsignificant. Community-dwelling participants are encouraged to engage in more LPA and cognitive activity to increase brain fitness. Further research may explore the distinctive effects of JPA.
