Summary:
Young adults who run or participate in other cardio
fitness activities may preserve their memory and thinking skills in middle age,
according to a new study. Middle age was defined as ages 43 to 55 in this
study. "These findings are likely to help us earlier identify and
consequently prevent or treat those at high risk of developing dementia,"
researchers said

Young adults
who run or participate in other cardio fitness activities may preserve 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 age was
defined as ages 43 to 55.
"Many
studies show the benefits to the brain of good heart health," said study
author David R. Jacobs, Jr, PhD, with the University of Minnesota in
Minneapolis. "This is one more important study that should remind young
adults of the brain health benefits of cardio fitness activities such as
running, swimming, biking or cardio fitness classes."
Cardiorespiratory
fitness is a measure of how well your body transports oxygen to your muscles,
and how well your muscles are able to absorb the oxygen during exercise.
For the
study, 2,747 healthy people with an average age of 25 underwent treadmill tests
the first year of the study and then again 20 years later. Cognitive tests
taken 25 years after the start of the study measured verbal memory, psychomotor
speed (the relationship between thinking skills and physical movement) and
executive function.
For the
treadmill test, which was similar to a cardiovascular stress test, participants
walked or ran as the speed and incline increased until they could not continue
or had symptoms such as shortness of breath. At the first test, participants
lasted an average of 10 minutes on the treadmill. Twenty years later, that
number decreased by an average of 2.9 minutes. For every additional minute
people completed on the treadmill at the first test, they recalled 0.12 more
words correctly on the memory test of 15 words and correctly replaced 0.92 more
numbers with meaningless symbols in the test of psychomotor speed 25 years
later, even after adjusting for other factors such as smoking, diabetes and
high cholesterol.
People who
had smaller decreases in their time completed on the treadmill test 20 years
later were more likely to perform better on the executive function test than
those who had bigger decreases. Specifically, they were better able to
correctly state ink color (for example, for the word "yellow" written
in green ink, the correct answer was "green").
"These
changes were significant, and while they may be modest, they were larger than
the effect from one year of aging," Jacobs said. "Other studies in
older individuals have shown that these tests are among the strongest
predictors of developing dementia in the future. One study showed that every
additional word remembered on the memory test was associated with an 18-percent
decrease in the risk of developing dementia after 10 years."
"These
findings are likely to help us earlier identify and consequently prevent or treat
those at high risk of developing dementia," Jacobs said.
