According to researchers, seniors who integrate cardiovascular activity into their lives, such as walking, would be lowering their risk of mental decline. For the study researchers surveyed nearly 18,800 women, ages 70 to 81 years, and asked them to rank their physical activity. The data show women who walked for at least 1.5 hours weekly at a comfortable pace had better cognitive health than those who walked less than 40 minutes per week.
Another study done showed men, too, can benefit from the routine of exercise. Researchers studied nearly 2,300 men, ages 71 to 93 years, and ranked their exercise levels for two years. The research showed men who walked more than two miles per day decreased their risk for dementia. Men who walked less than one mile per day increased their risk for dementia by 71 percent.
Thus researchers conclude that exercise and active lifestyles are associated with a reduced risk of cognitive decline in both women and men.
