Alzheimer's disease is a terrifying disease to be diagnosed with, both for those who suffer from it and for those who care for them. Does fitness, on the other hand, play a role in lowering the risk of Alzheimer's disease? People who are physically fit are less likely to get Alzheimer's disease than those who are not, according to a recent study.

The exploratory study was conducted by the American Academy of Neurology and will be presented at the 74th Annual Meeting of the Academy, which will be held in Seattle from April 2 to 7, 2022 in person and online from April 24 to 26, 2022.

"An exciting finding of this study is that as people's fitness improved, their risk of Alzheimer's disease decreased—it wasn't an all-or-nothing proposition," study author Edward Zamrini, MD, of the Washington VA Medical Center in Washington, D.C., and a member of the American Academy of Neurology, said. "As a result, people can strive toward making small modifications and increases in their physical fitness, which should lead to a reduction in their risk of Alzheimer's disease years later."

The Veterans Health Administration database contained 649,605 service veterans with an average age of 61 who were monitored for an average of nine years. They didn't have Alzheimer's disease when the trial began.

The cardiorespiratory fitness of the subjects was measured by the researchers. Cardiorespiratory fitness refers to how well the body transfers oxygen to the muscles and how well the muscles absorb oxygen during exercising.
