According to http://news.bbc.co.uk/1/hi/sci/tech/406334.stm, exercises using weights do not improve mental function, but walking (possibly any aerobic exercise) does.

O Wow, R., I almost missed you post.
I agree with this idea. IMHO, runners, joggers, walkers, hikers, mountain climbers...are all relatively more intelligent, and spiritually more advanced. I think it's the feet touching the earth, the heart rhythm, the increased blood flow (all over the body, including the brain), and the whole bodymind that flows while doing the exercise.
One tip for you: a few years ago, while working on my dissertation, I often got this writer's block that was extremely frustrating: I didn't know what to write. But when I took a brisk walk/jog/run, good (and brillient) ideas would suddenly appear in my mind, and lots of them. So if you have problems with that unfinished thesis of yours, perhaps you want to start power walks/jogs/runs and your thesis will just write itself...

I have a question about this quote from the article: "The non-walkers may have built up brawn, but that did nothing for their brains."
What does "may have built up brawn" mean? The question is, did they or did they not get stronger? If the strength building program got poor or no results in building strength, wouldn't that affect the conclusion that strength training programs don't affect brain function? Since the subjects were VERY de-trained individuals, the study should have seen GREAT changes in strength levels. If they didn't, it was a lousy strength training program. It is well-known that highly detrained individuals usually make great gains in strength on almost ANY strength program.
In another study BY THE SAME AUTHOR, "...exercise programs involving both aerobic exercise and strength training produced better results on cognitive abilities than either one alone."

The author seems to be contradicting himself here.

I think the walks could have stimulated the brain by
what they encountered on their walks and they also had to
Think more just to negotiate the walk no matter where they
walked. Just like they say that people who do puzzles and
other mental activities don't get alsheimers as often Even
when they have brain deterioration that is Thought to cause
it.
I wonder if other forms of aerobics, like walking a tread
mill produces the same results ? Weight training makes you
focus on doing the exercise as opposed to things you
encounter. I think a tread mill might be the same.

That would be great if the thesis would write itself. I'd be jogging, walking, and climbing rocks, walls, and trees all day long.
I think it's the feet touching the earth, the heart rhythm, the increased blood flow (all over the body, including the brain), and the whole bodymind that flows while doing the exercise.
But the same thing happens when lifting weight! It must be something else.

According to my dictionary, brawn means both muscular strength and muscles.
I am sure they got stronger because no exercise that increases muscle mass will do nothing to strength. Your first paragraph makes no sense to me. It just creates an impression of a desperate attempt to defend weight lifting.
Your reference to another study makes more sense. But with combination with the first study, it seems that if one's goal is to improve mental capasity, he or she sholdn't rely on weight lifting alone.

"According to my dictionary, brawn means both muscular strength and muscles. I am sure they got stronger because no exercise that increases muscle mass will do nothing to strength."
You should have looked up the word 'may', not the word 'brawn'. It was the use of the word 'may' that I was questioning, not brawn.'May' is "used to indicate a certain measure of likelihood or possibility." Sure, it's likely or possible that the participants improved in various measures of strength. But did they? Was it measured in this study?
HOW are you sure they got stronger? HOW are you sure they increased muscle mass? There is no evidence [from the news article] that the study participants actually got stronger OR bigger. No numbers, just an assumption. Where's the data?

I see what you are saing. You've got a point there -- there really was no data at all. All that was said is "The other half did stretching and toning exercises using weights."
In Reply to: Re: Questions about brain function/strength training link posted by R. on May 29, 2003 at 17:45:17:
That comment about "toning exercises" got me too. No decent exercise scientist would use the term. "Toning" can't be defined, it doesn't really exist in physiology except in the minds of lay people.

To do aerobic weight training. I've been doing it for more than 2 decades!

It seems to me every couple of months or so the topics of grain vs meat and walking vs weight-lifting would pop up and thereby start those long arguments about which one is better. Personally I think this new round is about the 4th or 5th time in my short life on the board. But seriously, I can't help laughing each time when I open this board and find piles and piles of heated new posts, arguing with lots of passion, as if one's life is depended on it. Oh man. Life is surely full of fun.

You're right, it does seem to get some people's dander up, doesn't it? But maybe we shouldn't speak as we are the same person, no? ;-)

Well, Eliza, if I ever had a double you might be it! At least HY was fully convinced that you and I are the same person he he he. He probably still thinks so.
O well, be well, my American double, whoever you are ;)

One of you can easily leave this board. Since we've gotten used to bing, may it Eliza.
In Reply to: Re: Questions about brain function/strength training link posted by R. on May 29, 2003 at 14:54:13:
it seems odd to expect physical exercise to increase mental
function unless it had something to do with blood flow.
Mental Exercise seems to be the way to do it.

could be the exuberent exercise got endorphins flowing and
relaxed you and allowed you to think better and clearer.

I think Eliza's scientific background can add a little balance to your mystical side, bing. And perhaps Eliza could use a little mysticizing. Who knows?
In Reply to: Re: Questions about brain function/strength training link posted by Vince F on May 30, 2003 at 00:02:34:
It most likely DOES have something to do with blood flow.

Thanks, R.

Be nice to Eliza, will ya?
I think Eliza is a wonderful person (according to a recent definition from Walt, a WP is someone who agrees with him. and me. Eliza agrees with both him and me, so). And she is extremely intelligent and sharp. You should be careful now--you may fall for her, hopelessly...

Sounds like a nice complement, doesn't it. And thanks for the compliment about my "mystical" side, cris.

Since weight training is usually considered ANaerobic, perhaps you could expand upon what you define as "aerobic weight training."
In Reply to: Re: It's a very simple matter posted by Lincoln on May 30, 2003 at 11:28:58:
All one has to do is lift weights with little rest in between sets to maintain heart rate in the desired aerobic range.
In Reply to: Re: Common occurance here? posted by bing on May 30, 2003 at 08:52:05:
For God's sake, Bing, maintain tighter connection to reality!

Yeah, It's obvious that R. has the hots for Miss Bliss, not cool brainy types like Eliza. Or cris. or PhillyLady.
In Reply to: Re: It's a very simple matter posted by Eliza on May 30, 2003 at 13:06:44:
Okay. Similar to H.I.I.T. (High Intensity Interval Training) which is short bursts of high-effort activity interspersed short rest periods. I've done similar with weights. Good for general all-around fitness.
In Reply to: Re: Questions about brain function/strength training link posted by R. on May 30, 2003 at 01:11:25:
then weight lifting doesn't increase blood flow to the
brain ? I would think it increases it everywhere. I still
think if you want to improve function of a Part of the
body that That part should be exercied and beains aren't
muscles so with all the blood flow it can still get flabby.

Is that right, R? you got the hots for me. hehehe.
Forget those cool brainy types, you cant cuddle up to a brain. LOL!
In Reply to: Re: Questions about brain function/strength training link posted by Vince F on May 30, 2003 at 16:23:32:
I agree with what you said.

Oh, yes, big time! Can't wait for those neuro-electronic connectors to become available. :)
A brain is only good for a BB, and one of the listed brains isn't good for that either.
In Reply to: Re: Common occurance here? posted by R. on May 31, 2003 at 01:49:55:
Now you have gotten me all excited about those neuro electronic connectors, R. Cant wait to hook up, and just go wild. :)
P.S. I think I know the 'listed brain' you are referring to, and it really is good for nothing.
In Reply to: Re: Common occurance here? posted by Miss Bliss on May 31, 2003 at 00:28:50:
"you cant cuddle up to a brain"
yeah, but you won't Bliss with a Miss either. You really should find someone with an IQ bigger than your shoe size R.

Ooooooh, that was a rather low blow, and from a brain no less! :)
