Recently, researchers from the University of Sydney in Australia published a paper in The Lancet" the lancet healthy longevity "A study was published on the page**. In the study, researchers analyzed 91,298 participants aged 68 years or older in the National Health Interview Survey (NHIS) cohort to collect physical activity information in the form of a questionnaire to analyze the relationship between exercise and Alzheimer's disease mortality.
Overall, 52Seven percent of the participants had no moderate physical activity and 80 percent had no vigorous physical activity.
On average 6During the 5-year follow-up period, a total of 2176 participants were recorded to die from Alzheimer's disease.
For strenuous physical activity, the study found a significant L-shaped association between 20 to 190 minutes of strenuous physical activity per week and Alzheimer's disease mortality.
Further analysis found that a minimum amount of strenuous physical activity of 40 minutes per week reduced Alzheimer's mortality by 9% for reducing Alzheimer's disease mortality.
The optimal amount of vigorous physical activity to reduce Alzheimer's mortality is 140 minutes per week, which reduces Alzheimer's mortality by 21%.
Applying this results to the United States, researchers estimated that 40 minutes of vigorous physical activity per week could prevent 12,238 Alzheimer's-related deaths per year and 37,710 Alzheimer's disease-related deaths per year if 140 minutes of vigorous physical activity per week could prevent more than no vigorous physical activity.
The analysis showed that 40 minutes of vigorous physical activity and 140 minutes per week of vigorous physical activity increased expected survival by 16 years and 23 years.
In summary, the results suggest that 20-190 minutes of vigorous physical activity per week can reduce Alzheimer's disease-related mortality, and the optimal amount of physical activity to reduce Alzheimer's mortality is 140 minutes per week, which can reduce Alzheimer's disease mortality by 21%.
