Those who had done the aerobic workouts showed less stiffness of the blood vessels in the neck, as well as increased blood flow to the brain.

The exercise program did not involve aerobic activities that significantly elevate the heart rate.įorty-eight of the study participants completed the full year of exercise training.
The other group entered a stretching and toning class that included stretches of the arms and legs, as well as the use of elastic bands to provide resistance and toning. They gradually built up to four or five exercise sessions each week lasting 30 to 40 minutes, including moderately intense exercises such as a brisk uphill walking that got the heart rate up to 85 to 90 percent of maximum. They began with three exercise sessions a week lasting 25 to 30 minutes, with a five-minute warm up and a five-minute cool down. One group began a supervised aerobic exercise program over the next year. The study participants ranged in age from 55 to 80, and they were randomly divided into two groups. The study adds to growing evidence that regular exercise may boost brain health and help to ward off Alzheimer’s disease and other forms of dementia.įor the study, researchers at UT Southwestern Medical Center enrolled 70 men and women with mild cognitive impairment, or MCI, a brain disorder marked by memory loss that half the time progresses to full-blown Alzheimer’s disease. A year-long aerobic exercise program that mostly involved brisk walking improved blood flow to the brain in older men and women at high risk of developing Alzheimer’s disease, according to a new report.
