Exercise May Slow Brain Disease

hiking.jpgAnother study has been published that supports a relationship between physical fitness and brain volume. This study explored the rate of brain shrinkage or cell loss in persons with mild Alzheimer’s disease. Subjects had their peak oxygen demand measured while running on a treadmill and this was related to their brain shrinkage as estimated by MRI scan.

Results indicate that those persons suffering AD who were more physically fit had less brain shrinkage than less-fit participants. Curiously, these same persons did not do significantly better on tests for mental performance. The authors suggested that there were not enough participants to see the difference in cognitive performance and that the study used only one measurement point which prohibited demonstration of a conclusion.

However, this study together with other research further underscores an important relationship between blood flow, cardiac health, and brain health (e.g. brain fitness).
