For the first in
a series of articles on brain health, we are starting with a quick tip
that works. Since research has proven that exercise boosts the health of
the brain, we can trust the experts and take action in our
lives.
Exercising three hours a week will keep the brain healthy,
according to a study recently published by researchers at the University
of North Carolina at Chapel Hill. The researchers compared two groups of
people over a ten year period. One group, aged 60 – 76 – exercised at
least 3 hours a week for 10 years. The other group led inactive lives,
exercising less than one hour per week for the same period of time. Each
volunteer received MRI and MR angiography to examine the
brain.
The active group had more small blood vessels and more
improved cerebral blood flow, according to J.Keith Smith, MD, PhD,
associate professor of radiology at UNC School of Medicine. The inactive
group had fewer small blood cells and unpredictable blood
flow.
Prior studies have shown that people who are active
experience less cognitive decline, suggesting a possibility between
improved blood flow and a slower decline of cognition. Why not begin
again and commit 3 hours a week to exercise? It would be wise to consult
your physician before jumping into an elevated heart rate. Also, being
cautious about one’s own body and limits or boundaries is always
wise.
Target heart rate calculations have changed and there is
new information out about intensity and duration of a work out, so
consulting a physician and a certified trainer is the best plan. Once
this is accomplished, a lifestyle change including weekly exercise
awaits. Here’s to your health!
“If you want to walk, run, bike, swim and or dance, there are
countless options ~ the most important thing is to choose an activity
you will enjoy and commit to.â€Lorrie Jones
