Kyle O. Hardman, Dolores A. Christensen, Phillip M. Bergreen, Mark Krause Research in psychology and neuroscience is now finding important links between exercise and cognitive abilities such as memory. These findings are emerging in both animal and human studies. The present study tested whether physical activity is related to working memory, long-term memory, and metamemory in college students. Our results indicate that some aspects of memory ability are related to physical activity in college-aged adults. Vigorous physical activity is associated with enhanced spatial memory performance. This finding parallels animal work showing that spatial memory is enhanced by frequent physical activity. Previous work has shown that reaction time and vocabulary learning by college-aged students are acutely enhanced following exercise. Our results suggest that these effects may not last beyond periods immediately following exercise.
