Physical fitness may decrease risk of developing dementia later. A new study from Sweden suggests that exercising in midlife boosts heart and benefit the brain.
According to the study, middle-aged women with high cardiovascular fitness, or high stamina, were nearly 90% less likely to develop dementia decades later. The study findings were published in the journal Neurology today.
At the beginning of the study, researchers analyzed data from 191 women in Sweden ages 38 to 60. They conducted an exercise test of the middle-aged women in 1968. The women tasked to cycle until they felt exhausted on a stationary bike.
After that researchers tracked the women for 44 years and they found that 32 percent of the women with a low fitness score developed dementia during the study time and e highest dementia rates were found in women who couldn’t complete the workout.
Though the study discovered an association between cardiovascular fitness and dementia development risk but, couldn’t prove that exercise prevented dementia. We already know that there is a relationship between exercise and decreased dementia risk, but the new findings results are considerable that claims physical fitness may decrease risk of developing dementia later in life.
“The literature has not yet settled on an amount or type of exercise that is going to be key, although the bulk of literature has suggested that aerobic exercise is what you need to be doing,” said Keith Fargo, director of scientific programs and outreach at the non-profit Alzheimer’s Association. “That doesn’t mean you have to compete in triathlons but more than a 10-min dog walk would be a good idea,” Fargo added.
