Exercise Provides Shield Against Parkinson's

Exercise

Weight loss is not the only benefit people gain from exercising. Researchers found that men who exercised regularly and vigorously early in their adult life lowered their risk for developing Parkinson's disease when compared to men who did not.

What is Parkinson's disease? It is a progressive nervous system disease that usually occurs after age 50. It destroys brain cells that produce dopamine (a brain chemical) and is characterized by:

  • Rigidity
  • Muscular tremor
  • Postural instability
  • Slowing of movement

Uncovering the Parkinson's-Exercise Link

To determine the relationship between physical activity and Parkinson's disease, researchers involved more than 48,000 men and 77,000 women--who were free of Parkinson's disease, cancer or stroke--in a study. Participants completed comprehensive questionnaires on disease, lifestyle practices and physical and leisure time activities (beginning in 1986 and updated every two years through 2000). Throughout the study, a total of 387 cases of Parkinson's disease were diagnosed--252 men and 135 women.

The study showed:

  • The most physically active men at the start of the study lowered their risk of developing Parkinson's disease by half, compared to men who were least physically active

  • Men who reported engaging in regular physical activity in early adult life lowered the risk for Parkinson's by 60 percent, compared to men who did not

  • Women in the study who participated in strenuous activity in the early adult years were also associated with a lowered risk of Parkinson's (yet this link was not statistically significant and there was not clear relationship between physical activity later in life and Parkinson's risk)

Dr. Mercola''s Comments Dr. Mercola's Comments:

You may remember a popular article I ran about the newest weapon--and probably the healthiest--you can use to fight Parkinson's disease: Exercise. Well, the article above provides additional confirmation of the therapeutic benefits of exercise.

However, what concerns me is that most people, especially doctors, don't tend to appreciate just how powerful exercise is.

The Exercise Drug

The way I see it: Exercise needs to be viewed like a drug. In other words, you have to be very careful with the dosage--if the dose is not high enough, it will not work.

It is important to set a goal of 60 to 90 minutes per day, every day. Obviously, depending on your current condition, you may need to work slowly up to this level. My experience is that weight-bearing exercises, such as walking, jogging, running, Nordic Track and Health Rider are better than cycling and swimming. If you have access to a health club, my favorite piece of equipment there is the elliptical machine.

It is also important to seek to include some strength training exercise in your program in addition to the cardiovascular or aerobic type training. This will complement your fitness and help provide a well rounded structural frame that will improve your overall health. I believe that aerobic fitness is a higher priority than strength training, so if you only have time for one then do the cardio exercises as that will impact your insulin levels the most. But it is important to squeeze in twice-weekly strength training sessions if at all possible.

However, one of the biggest obstacles faced by people who haven't exercised in some time is how to get started. Just the thought of starting an exercise program can be intimidating.

Therefore, whenever patients ask me what kind of activity is best to get started, my answer is always the same: Walking is a wonderful way to start exercising. It is very low impact so it is easy on the joints, and humans have been getting exercise this way for thousands of years. Most people find it is simple and enjoyable to fit a walk into their day.

Walking doesn't require much training and the only equipment needed is a good pair of walking shoes. You can walk just about anywhere and you can do it anytime.

Why the Walking Workout?

If you are starting out in poor shape, slow-paced walking will produce benefits, but if you are starting out in better condition, you will need to walk faster and/or farther to see any results. Regardless of your starting level, the more vigorous your walking pace, the more dramatic the conditioning effects will be. When walking for exercise you should walk at a steady pace that is fast enough to cause your heart rate to raise.

Note: Don't be concerned that the above article prescribes vigorous physical activity to prevent Parkinson's--as long as you are exercising everyday that is certainly enough to get started. Eventually though, you will work up to the point where you'll find you can handle a regular, vigorous exercise program.

In my experience most people increase their fitness level relatively rapidly while walking and the only way they can continue to stress themselves enough while walking is to walk on a treadmill with an incline.

You can learn more about incorporating the right exercise program into your life by reading Paul Chek's newest book, How to Eat, Move and Be Healthy! Chek's book challenges you to take control of your health and gives you the steps to designing your own individual exercise program. You will find the many descriptive "how to" illustrations both easy to follow and implement into your exercise routine.
