Areobic exercise may help delay or improve signs of Alzheimer's a little

Aerobic exercise may be more effective than other types of exercise in slightly delaying as well as improving signs of Alzheimer's disease says a new study.

Alzheimer's disease is a brain disorder that destroys memory and thinking skills over time. It is the most common form of dementia in older adults.

Findings published in the Journal of the American Geriatrics Society

The World Health Organisation has recommended that older adults must exercise for a certain amount of time every week. This includes 150 minutes a week of moderate exercise like brisk walking, 75 minutes a week of vigorous aerobic training, or a combination of the two types.

It also recommends older adults perform muscle-strengthening exercises on at least two or more days a week.

The findings looked at 19 studies that examined the effect of an exercise training program on cognitive function in older adults who were at risk for or diagnosed with AD. Of the 1,145 participants, 65% were at risk for AD and 35% had been diagnosed with AD.

The study found that older adults who did aerobic exercise by itself experienced a three times greater level of improvement in cognitive function than those who participated in combined aerobic training and strength training exercises.

This study may be the first to show that for older adults who are at risk for or who have AD, aerobic exercise may be more effective than other types of exercise in preserving the ability to think and make decisions.
