Keep young adults who are running or other cardio-fitness activities can participate in their memory and thinking skills in middle age, according to a new study published in the April 2, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology. Middle Ages was defined as age 43 to 55.
"Many studies show the benefits to the brain or the good health of the heart," said study author David r. Jacobs, Jr., PhD, with the University of Minnesota in Minneapolis. "This is an important study that health benefits of cardio-fitness activities like swimming, cycling or cardio-fitness courses run, should remind young adult brain."
Cardio fitness is a measure of how well your body exercise transports oxygen to your muscles, and how well your muscles while absorb the oxygen.
For the study, 2,747 healthy people with an average age of 25 treadmill were tests in the first year of the study and then again 20 years later. Cognitive tests 25 years after the beginning of the study tasks measured psychomotor speed (the relationship between thinking skills and physical activity), verbal memory and executive function.
Had the treadmill test, which corresponded to a heart cardiovascular stress test, participants walked or ran as the speed and slope increases, until she could be discontinued, or symptoms such as shortness of breath. Participants at the first trial lasted an average of 10 minutes on the treadmill. Twenty years later, the number of an average 2.9 minutes decreased. For each additional minute people on the treadmill at the first test completed reminded 0.12 more words right on the memory test or 15 words and correctly replaced 0.92 more numbers with meaningless symbols in the test or psychomotor speed 25 years later also adjusted for other factors such as smoking, diabetes and high cholesterol.
People who had smaller declines in their time on the treadmill test 20 years later concluded were rather reduced on the exam as more powerful had larger executive function. In particular they could state more properly printing ink (written in green ink, the correct answer was for the word "yellow", "green").
"These changes were significant, and while they may be modest, they were greater than the effect of one year of aging," Jacobs said. "Other studies in older patients have shown that these tests to develop among the strongest predictors of dementia in the future." "One study showed that each additional word reminded the memory test with an 18 - percent decrease in the risk of developing dementia after 10 years."
"These results are likely to help us identify and therefore used to prevent or treat high risk of developing dementia", said Jacobs.
