Keep Your Brain Young With Exercise

Scientists have demonstrated that moderately active rats have

healthier DNA and more robust brain cells than their less active

counterparts. This is the first study to show that lifelong

exercise actually decreases cellular aging in the brain.

In the study, the animals were not forced to run; they only did

as much exercise as they found enjoyable -- what would translate

to a daily 30-minute walk or a light 1-mile run in a human.

Brains Like Rats a Quarter of Their Age

At the end of the experiment, the brains of the rats were

examined. The more active rats were found to have fewer

byproducts of oxidative stress in their brains. In fact, the DNA

for those animals, after two years, looked much like those of

their younger counterparts of only about 6 months of age.

Oxidative damage in the brain contributes to memory loss, and

has been implicated in Alzheimer''s disease and Parkinson''s

The next step in the research would be to determine which

natural chemicals and mechanisms are triggered by exercise to

Dr. Mercola''s Comment:Exercise is, without question, one of the

most powerful tools you can use to help you achieve optimal

health. It is my belief that it is virtually impossible to

achieve without. You can''t pay someone to do it for you. You

I believe this is related to our requirement to have hard

physical labor to obtain our food. Modern society has replaced

the necessity of manual labor but not our genetic requirement to

work. So exercise is merely the replacement for work that most

of us do not do in our normal jobs.

It certainly is true for me as I am typically in front of my

computer monitor for 10-16 hours a day and is one of the primary

reasons why one of my highest priorities is to exercise

regularly. Believe me I plan my schedule around my exercise, not

the other way around. This way exercise is never crowded out due

to schedule conflicts. It just needs to be a high priority if

you are going to do it.

Fortunately even light exercise can make a world of difference

to the health of these rats.

But as one scientist wisely pointed out in this study, there''s

one major difference between rats and humans. Putting an

exercise wheel in a small cage will entertain and boost the

physical and mental health of rats, because they will use it.

But buying an exercise bike or a health club membership doesn''t

mean you''ll ever get around to using it.

If your goal is to optimize your health, starting an exercise

program is just as important as retooling your diet. To get you

headed in the right direction, try viewing exercise like a drug

that needs to be prescribed precisely to achieve the most

The key to exercising effectively is to make sure the variables

below are properly addressed. By doing so, you will ensure all

your hard efforts are not wasted and are having a positive

effect on your body. To aid you in your exercise efforts, there

are three important variables to keep in mind:Length of

time Frequency Intensity I encourage my patients to gradually increase the amount of time

they are exercising to 60 to 90 minutes a day. Initially the

frequency is daily. This is a treatment dose until they

normalize their weight or insulin levels. Once normalized, they

will only need to exercise three to four times a week.

encourage you to consider reviewing it. I do plan on doing a

You should exercise hard enough so that it is difficult to talk

to someone next to you. When you are exercising that hard your

cardiovascular system is under such a significant amount of

stress that the mere act of talking makes you unable to provide

your body with enough oxygen. However, if you cannot carry on a

conversation AT ALL, then you have gone too far and need to
