I put this in “News/Activism” instead of “Chat” because, given the importance of this study’s findings to older Freepers, it might get wider readership in “News.”
Senior lifestyle choices are greater than ever.
I’ve never heard of “newborn neurons generated by exercise”. I wonder what they mean.
bump!
In my case, I have noticed that my brain behaves more like it did when I was a child--both good and bad.;-)
I was a hyperactive child and had what I would call a hyperactive brain in that I had to work hard to stay focused. Once I did learn to focus, there were benefits that came from utilizing what was both a weakness and a potential strength. Long story, short, I noticed that my brain is once again mildly hyperactive.
Plus, I noticed significant improvement in memory and I was already a heavy exerciser.
As an aside, my HIIT consists of pushing almost to exhaustion in the intensity portions of my program. I have done Crossfit (stopped that recently due to back problems that cropped up), I do a HIIT classes at my local Wellness Center (4 times a week), and a couple of times a week I do a HIIT routine in which I do a rotation through my gym's rower, ski-erg, and Schwin Airdyne bike (usually 3-6 rounds which consist of 10-20 calories--1+ or 2+ minutes respectively--at each machine).
Over the past 20 years, researchers have begun to get at the root of these benefits, with studies pointing to increases in the volume of the hippocampus, development of new neurons, and infiltration of blood vessels into the brain.

Does getting up to change channels count as an “exercise burst?”
If you have Medicare Advantage check out the Silver Sneakers program for seniors. It’s not a high intensity program, but focuses on fitness, balance, eye-hand co-ordination—gets you moving and keeps your mind alert. Plus it’s free.

Years ago there were many studies showing the benefits of imagined sports training vs actual sports training.
I would like to combine these two studies to determine if “imagined” running functions as an exercise burst to increase brain function.

Elliptical machines are a quiet, high-intensity alternative to treadmills that are less stressful on the knees.
The last time I engaged in high intensity exercise at a gym, I forgot the combination to my lock.....
LOL..any exercise that involves legs is pretty much out of the question (bad hip and knee).
I do “Heavyhands” type exercise using the original red AMF weights, which can be either moderate or high intensity and easily switch between the two states.
That sounds like a lot of work.
I’m sorry, what were we talking about?
(Good advice though...and a reminder to keep up exercise in the golden years...)
What was I reading?
Good, because these days, walking up the stairs can be high intensity exercise for me . . . .
Back to the basics. Eat right, exercise daily both weights (lifting heavy things to build or keep muscle) and walk, and take vitamins (take what your body does not make)! Very simple.
twelve weeks is an inadequate study period to draw a measurable conclusion.
The exercise is very important but hte period is so short that the conclusion is suspect.
For the Record: In july I began two trips per week to the Y to use the strength machines. The increase in strength lost is dramatic. the fact I can easily get up off the floor is a very measurable activity.
I see no result on memory.
