accelerometer unit measured habitual physical activity of each participant, with software subsequently calculating total counts and total kilocalories expended each day. In addition, each participant underwent a comprehensive battery of cognitive tests, which included the; Mini Mental State Examination (MMSE), California Verbal Learning Test (CVLT) and Rey Complex Figure Test (RCFT). Spearman ranked order correlations were calculated between habitual physical activity levels and cognitive test scores using age, gender and estimated IQ as co-variates. Results: Significant positive correlations were observed between physical activity average total counts/day (recorded by the accelerometer), and various cognitive measures, including; CVLT Learning Score T1-5 (r 1⁄4 .137; p 1⁄4 .047), CVLT Retention (r 1⁄4 .138; p 1⁄4 .046), CVLT Delayed Recall (r 1⁄4 .141 p 1⁄4 .043) and RCFT 3 minute delay (r 1⁄4 .168; p 1⁄4 .020). No significant correlation was observed between physical activity and the Mini Mental State Examination score. Conclusions: The use of accelerometers addressed the potential inaccuracies associated with the use of physical activity questionnaires. Collection of reliable data showed positive associations between physical activity and specific elements of cognition (focused on episodic learning and memory). Our results indicate that people participating in higher levels of physical activity are more likely to experience enhanced cognitive performance, a factor that has been linked to protecting the aging brain against AD.
