The results of the study were published in the journal PLOS ONE.
The team focused on the relationship between exercise and brain metabolism for years.
"For improved brain function, the results suggest that it is not enough just to exercise more," said lead author Eric Vidoni, associate professor of neurology at University of Kansas Medical Center.
The randomized controlled trial attempted to determine the ideal amount of exercise necessary to achieve benefits to the brain.
Trial participants were placed in a control group that did not have monitored exercise, or they were put into one of three other groups.

The study said that the intensity of the exercise appeared to matter more than the duration.
A number of research studies is also being conducted on how exercise may help prevent or delay the onset of Alzheimer's.
