Low-intensity physical activity may help reduce risk of dementia: study


There is enough evidence to prove the benefits of exercise and the important role it plays in leading a healthy lifestyle. Now, a new study led by Michelle Voss of the University of Iowa at Iowa City suggests that engaging in even light physical activities, such as housework, may help reduce the risk of dementia in the elderly. .

“While regular exercise benefits aspects of brain health that decline with age, the benefits of training vary widely in older adults. The factors behind this variability are not well understood, but may illustrate how to improve the benefits for a wider population, ”said the results presented at the Cognitive Neuroscience Society seminars in San Francisco.

The study found that “those who had the most improvements in brain network connectivity and the greatest cognitive benefits after single workouts also had equally large positive effects at the end of their training programs. coaching”.

Research has shown how important it is to stay physically active. They’ve made a connection between physical health and brain systems that improve every time you exercise.

Another study, published in the British Journal of Sports Medicine, used data collected from surveys between 1997 and 2008 to estimate the activity levels of 88,140 people aged 40 to 85, and linked that data to deaths. registered until December 31, 2011.

They calculated participants’ total leisure-time physical activity using definitions from the 2008 U.S. guidelines, which roughly equate to one minute of vigorous activity such as running, fast cycling, or competitive sports in two minutes. moderate-intensity activity, such as brisk walking, gardening or dancing. Even moderate physical activity, such as walking or gardening, can reduce the risk of death from cardiovascular disease, cancer or any other cause, according to a study.
