Despite our best fitness intentions, life can sometimes get in the way. Whether it's the demands of work or family, an old injury, or aching joints, it's not always easy to prioritize our fitness, especially as we age.
The benefits of staying in shape, though, are great for both body and mind. By keeping moving, we can decrease the risk of major illnesses such as heart disease, stroke, cancer, and type 2 diabetes. How fit we are can also influence the health of our brains.
Workouts using the best elliptical machines and best exercise bikes are a great low-impact option for exercisers of any age and ability, especially those with joint pain. This is good news since, according to new research released by the American Academy of Neurology (opens in new tab), the fitter we are, the more we may be able to decrease our risk of developing Alzheimer's disease.
The study, which measured participants' cardiorespiratory fitness, found that those with the highest fitness level were 33% less likely to develop Alzheimer's disease than those in the least fit group. However, it doesn't seem to be an all-or-nothing proposition.
The research suggests it's more of a sliding scale, with the risk of developing Alzheimer's decreasing in line with the participant's fitness level. For instance, the second-fittest group was at 26% lower risk, while the middle fitness group was 20% less likely than the least fit participants.
The researchers did note, though, that you could get into the highest fitness level by taking a brisk daily walk, clocking up two and a half hours or more per week. You don't have to be pacing through to get the benefits either, as you can walk slower to burn more fat and lose weight sustainably.
"The idea that you can reduce your risk for Alzheimer's disease by simply increasing your activity is very promising, especially since there are no adequate treatments to prevent or stop the progression of the disease," said the study's author Edward Zamrini, MD, of the Washington VA Medical Center.
"So people can work toward making incremental changes and improvements in their physical fitness, and hopefully that will be associated with a related decrease in their risk of Alzheimer's years later," he concluded.
While this study focused on cardio fitness, we know that to maintain strong bones and muscle tone as we age, it's also essential to include some form of resistance training into your routine. That doesn't have to mean lifting heavy weights, though.
The important thing is to make sure we are doing something rather than nothing because the more we can build our fitness, the greater protection we are likely to afford our bodies and minds.
