Use it or lose it continues to reverberate as I learn about work done trying to understand aging and its effect on the human brain. Here is a study published in the journal Frontiers in Aging Neuroscience.
“Exercise has the beneficial effect of slowing down or even counteracting age-related decline in mental and physical capacity,” says Dr Kathrin Rehfeld, lead author of the study, based at the German center for Neurodegenerative Diseases, Magdeburg, Germany.
From animal research, it is known that combining physical activity with sensory enrichment has stronger and longer-lasting effects on the brain than either treatment alone. For humans dancing has been suggested to be analogous to such combined training. Here we assessed whether a newly designed dance training program that stresses the constant learning of new movement patterns is superior in terms of neuroplasticity to conventional fitness activities with repetitive exercises and whether extending the training duration has additional benefits.
The study was designed as an 18-month controlled intervention. It was approved by the ethics committee of Otto-von-Guericke University, Magdeburg. Some 52 healthy elderly individuals (63–80 years) recruited via announcements in local newspapers were screened for the study. They were then randomly assigned to either the dance or the sport group. Assessments were performed at baseline, after 6 and after 18 months of training. Continue reading
Getting through December in a four season climate like Chicago is a dicey experience for a guy who wants to ride his bike every day. You just don’t know what the weatherman will be serving up on any given day.
December usually has some of the most bizarre offerings, unfortunately. However, this year was one for the record books. No snowfall of an inch or more since March. This was the third most snow free season on record with 0.9 inch the lowest since 1939. The year 2012 was the warmest in Chicago’s 142 year observational record dating back to 1871.
Easily mistaken for Tony, this hot-looking guy is from Shawn Jantzen’s J2 Studios. One hot set of wheels.
I just finished adding up my bike riding for the year and it comes to, wait for it … 8,433 miles. I don’t know if you are impressed, but I am. This mellow December has been most helpful in my biking. Normally, we have snow and really difficult weather for riding at all, let alone virtually every day. This year, as you can see from the first paragraph – warmer and less snow. I bought a new car on February 25. I have driven it 4200 miles.
This cycling total is most gratifying to me because last year I rode 6,300 and thought I had begun to slow down due to my age. In 2010, the prior year, my total was 7,111 which was the most I had ever ridden. I was not surprised when I slid back the following year.
The 8,433 miles comes to a daily average – 366 days in 2012 – of 23.04 miles. A 23 mile ride lasts around two hours and burns about 1000 calories, thus expanding my gustatory horizons for the remainder of the day. It also works my heart and lungs and pumps up fresh oxygen to my brain creating new neurotransmitters.
