Researchers followed 650,000 adult men, average age of 61 years, for 9 years. None of the men had dementia at the start of the study. Fitness was evaluated by ability to complete a treadmill walking test.
Results: The men with the lowest fitness levels were over 30% more likely to have Alzheimer’s by the end of the study.
But even small improvements in fitness were associated with significant reductions in dementia risk.
However, matching the highest levels of fitness recorded in the study is not difficult –a brisk walk for 15 minutes every day is enough!
