More Muscle Strength equals Less Risk of Alzheimers

I’ve written several posts in the past which connected physical exercise to brain fitness.  Well I just came across a news article today on yahoo which further highlighted this connection.

The article reported the results of a study performed by Dr. Patricia A. Boyle and her colleagues of Rush Alzheimer’s Disease Center in Chicago. They found that the greater a person’s muscle strength, the lower their likelihood of being diagnosed with Alzheimer’s. The same was true for the loss of mental function that often precedes full-blown Alzheimer’s.

The researchers initially measured the strength of nine muscle groups in the arms and legs of 970 dementia-free men and women 54 to 100 years old (their average age was around 80). During a four year follow-up, 138 people in the study developed Alzheimer’s. These individuals were older and had worse mental function than the rest of the study participants. They also were weaker. They found that muscle strength had a strong influence on the risk of the disease. People who ranked in the top 10 percent for muscle strength were 61 percent less likely to develop Alzheimer’s than the weakest 10 percent. Stronger people also showed a slower decline in their mental abilities over time.

“These findings support the link between physical health and cognition in aging and the importance of maintaining good physical function and strength,” Boyle told Reuters.

“Good physical health is important for good brain function.”

  1. Well logically and medically this information is 100% correct. The risk of Alzheimer’s getting in to you are very much less if you have good muscle strength. The best way to gain good muscle strength is for improved and balanced diet with all nutrients.

  2. Very interesting, i wasn’t aware that muscle strength could be directly associated with brain ‘fitness’. I am actually going to look into this area a little more now, thanks for sharing this information.

  3. While I tend to agree with what is written here due to my experience in strength and conditioning, I would submit that a raw foods diet is probably a more important factor. We are starting to see people with Alzheimer’s symptoms at increasingly younger ages. To me this raises a red flag that it has something to do with modern western diets, the packages they are held in, vaccines, or something else that we wouldn’t readily think about. There is no money to be made in keeping a population healthy while there is a fortune to be made in keeping us dependent on drug companies, researchers, etc for diseases that were virtually unknown or extremely rare in the past that are increasingly commonplace today.

  4. I never would have thought that there would have been a bridge between alzheimers and muscle tone. Reading this makes me want to head to the gym and build more muscle tone. Alzheimers is a scary disease. It is nice to see some research that is making connections on potential causes.

  5. Very good blog post that covers a very interesting study. I was born left handed, but hit the end of the public school era where they trained you to be right handed – maybe that’s why my studies shot ahead of other students when I was young. I’ve heard this before, but didn’t have any sources to back it up. Thanks for the links to help my study of this interesting topic!

  6. Hello, I think your website might be having browser compatibility issues.
    When I look at your website in Firefox, it
    looks fine but when opening in Internet Explorer, it has some overlapping.

    I just wanted to give you a quick heads up! Other then that, awesome blog!

  7. When the researchers looked at different types of muscle strength separately, they found that grip strength and breathing-muscle strength had an independent effect on Alzheimer’s risk, but arm and leg strength didn’t.
