Summary
This study looked at whether 12 weeks of moderate exercise, three times a week, can improve memory and change gut bacteria in healthy adults aged 45 to 65. Researchers measured memory tasks and analyzed stool samples. The goal was to understand how exercise might help keep the brain healthy during middle age.
