“An early-morning walk is a blessing for the whole day.” 
~    Henry David Thoreau

 

 

I recently read an article in the L.A. Times confirming that a single bout of vigorous exercise releases norepinephrine which can enhance memory in seniors.  Researchers at the University of California in Irvine "recruited 31 healthy older adults with an average age of 69, and 23 subjects who had been diagnosed with 'amnestic' mild cognitive impairment -- memory loss that is problematic but which falls short of Alzheimer's disease. All were shown a series of 20 emotionally positive images -- beautiful landscapes, baby animals, sports scenes. And then, half of those in each group were put on treadmills to exercise for six minutes at 70% of their aerobic maximum. Subjects in the other half of each group were allowed to sit quietly."

 

An hour after the workout (or sit) the subjects were given a "free-recall" test and asked to describe in detail the photos they had seen.  The subjects with normal memory function had increased recall of 30%, and those with amnestic mild cognitive impairment who were included in the exercise group improved their recall even more by remembering twice the number of photos and details than did those who didn't exercise.  http://www.latimes.com/health/boostershots/la-heb-memory-seniors-exercise-20121128,0,6260485.story.  Researchers further determined that for both groups even a brisk walk around the block boosted recall of information learned just before the walk.

 

An earlier study, funded by the National Institute on Aging, was conducted at the University of Colorado in Boulder reflecting that a small amount of physical exercise can protect seniors from long-term memory loss which may happen suddenly following infection, illnesses or injury.  "Past research has shown that exercise in humans protects against declines in cognitive function associated with aging and protects against dementia. Researchers also have shown that dementia is often preceded by bacterial infections, such as pneumonia, or other immune challenges."  CU-Boulder Research Associate Ruth Barrientos stated that the study found that "small amounts of voluntary exercise prevented the priming of microglia, the exaggerated inflammation in the brain, and the decrease of growth factors." http://www.colorado.edu/news/releases/2011/08/09/small-amount-exercise-could-protect-against-memory-loss-elderly-cu-study.

 

We all know exercise is good for our bodies but it is important to know that it is equally necessary for our memory and mental well-being.   To stay healthy mentally and physically we must keep a positive attitude, endeavor to have a full and creative life ... and, by all means, keep on moving.♥

 

 

 





"If you don't use it, you lose it."  I read in the paper this morning about three women in their 70's who are still running marathons.  They all look terrific! 

Exercise keeps our bodies and minds healthy.  I met a 91 year-old woman the other day who remains fairly agile -- she still organizes and orchestrates a huge volunteer effort each year with several people working under her.

There are advantages to aging ... such as the SilverSneakers program.  My Medicare insurance plan offers SilverSneakers and I am so pleased with it.  (Check it out here:  http://www.silversneakers.com/.)  I can exercise at Curves, where I have met so many nice ladies, or the local YMCA for free ... as long as I go regularly.  The YMCA has classes specifically designed for seniors, including cardio fitness and even Zumba (which Curves also offers).  In addition, my Medicare plan offers discounts at Weight Watchers.  If your insurance plan offers a similar program, please share it with us. ♥
