Higher aerobic fitness associated with better word production skills in healthy seniors

Here we have more good news on the exercise/brain front. Eat less; move more; live longer really works on all levels it seems.

Healthy older people who exercise regularly are less inclined to struggle to find words to express themselves, research led by the University of Birmingham has discovered.

Researchers found that older adults’ aerobic fitness levels are directly related to the incidence of age-related language failures such as ‘tip-of-the-tongue’ states.

The research, published in Scientific Reports, is the first of its kind to investigate the relationship between aerobic fitness levels and temporary cognitive lapses, such as not having a word come to mind when speaking – known as a ‘tip-of-the-tongue’ state.

People in a tip-of-the-tongue state have a strong conviction that they know a word, but are unable to produce it, and this phenomena occurs more frequently as we grow older. Continue reading

Stronger people have healthier brains – Study

Herewith another log on the fire. Eat less; move more; live longer remains the mantra here. I was aware of the brain benefits of aerobic exercise, now, it seems that strength training also contributes.

A study of nearly half a million people has revealed that muscular strength, measured by hand grip, is an indication of how healthy our brains are.

Dr. Joseph Firth, an Honorary Research Fellow at The University of Manchester and Research Fellow at NICM Health Research Institute at Western Sydney University, crunched the numbers using UK Biobank data.

Using data from the 475,397 participants from all around the U.K., the new study showed that on average, stronger people performed better across every test of brain functioning used. Continue reading

Sweat – Don’t Forget: Exercise Breaks Improve Learning

It is becoming clearer to me with every day that passes – exercise is the key to a better life. Everyone understands the first level – that our bodies crave movement. But new research continues to unearth fresh benefits for our bodies globally. Every aspect of our life and being tends to benefit from exercise. Just scroll back through this blog at the last 10 posts and you will find one after the other example of this.

New research from a team of scientists at McMaster University suggests that brief exercise breaks during lectures can help university students focus their attention, retain information and improve overall learning.

While the benefits of exercise are well-known for school-aged children, this is the first study to examine the benefits for adult students. The findings are published online in the Journal of Applied Research in Memory and Cognition.

For the study, researchers examined three groups of first-year Introductory Psychology students, who were tasked with watching a 50-minute online lecture. One cohort performed a series of brief, calisthenic exercises at regular breaks during the lecture, another took breaks but played a video game, and a final group did not take any break.

Physical Activity May Influence the Health of Future Offspring

It just keeps getting better. The mantra of my blog is eat less; move more; live longer. That has always referred to yourself, present and future, mind and body. Now comes a fascinating study from Germany that suggests that the exercise you do today may well influence the health of your future offspring. What could be better than that?

Physical and mental exercise is not only beneficial for your own brain, but can also affect the learning ability of future offspring – at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate in both the brain and germ cells following physical and mental activity.

Prof. André Fischer and colleagues from the German Center for Neurodegenerative Diseases (DZNE) in Göttingen and Munich and the University Medical Center Göttingen (UMG) report these findings in the journal Cell Reports.

It is known that physical activity and cognitive training also improve learning ability in humans. However, it is not so easy to study in humans whether learning ability can be inherited epigenetically. NeuroscienceNews.com image is in the public domain.

Exercise helps overcome negative effects of stress – Study

I have written numerous times about using deep breathing to combat stress. Turns out that a recent study from Brigham Young University says that exercise helps to combat negative effects of stress.

The study, newly published in the journal of Neurobiology of Learning and Memory, finds that running mitigates the negative impacts chronic stress has on the hippocampus, the part of the brain responsible for learning and memory.

“Exercise is a simple and cost-effective way to eliminate the negative impacts on memory of chronic stress,” said study senior author Jeff Edwards, associate professor of physiology and developmental biology at BYU.

“The ideal situation for improving learning and memory would be to experience no stress and to exercise,” Edwards said. “Of course, we can’t always control stress in our lives, but we can control how much we exercise. It’s empowering to know that we can combat the negative impacts of stress on our brains just by getting out and running.”

To see the paper online, click here. Ten undergraduate BYU students served as co-authors on the paper, included David Marriott, who began the project for his undergraduate honor’s thesis. First author Roxanne Miller graduated in December with her Ph.D. and the research was part of her dissertation.

“Even though we will never be able to completely remove stress from our lives, it is nice to know that we can go out and do cardiovascular exercise for 20 minutes a day to help keep the stress from overwhelming our brains,” Miller said.

Send your brain a Valentine

We are sending our loved ones greetings cards and chocolates next week. Let’s not forget that two pound organ in our heads that keeps the show on the road.

Here are 10 tips from the Alzheimer’s Association to help protect your brain from decline  as you age. Please don’t wait till you are in your 60’s to start thinking about your brain health. The sooner your pay attention to it the better off you will be. 
1 Break a sweat
Engage in regular cardiovascular exercise that elevates your heart rate and increases blood flow to the brain and body. Several studies have found an association between physical activity and reduced risk of cognitive decline.

I write about exercise and the brain regularly. Check out my Page – Important facts about your brain (and exercise benefits) to learn more about this. 

2 Hit the books
Formal education in any stage of life will help reduce your risk of cognitive decline and dementia. For example, take a class at a local college, community center or online. Continue reading

The impact of exercise on the brain

On the premise that one picture is worth 1000 words, here are 2000 words worth of pictures. Regular readers know I feel strongly about the positive impact of exercise on the brain.

Feeding your body and your brain – Infographic

For the record, this has nothing to do with losing weight, but everything to do with providing your body and your brain with proper nourishment. I especially liked the final segment which points out how your brain benefits from exercise.

Tufts on Exercise and Brain Health

As regular readers know I feel very strongly about the benefits of exercising, not only on the body, but equally on the brain. You can check out my Page – Important Facts About Your Brain (and Exercise Benefits) for further details. So, I was thrilled to see the latest from Tufts on that subject.

Tufts Health and Nutrition Update says, “A new study reports that the more physically fit you are when you’re younger, the more likely you are to keep your brain sharp as you get older. But there’s also good news for those who slacked off in their youth: Even starting to get more fit now might still improve your cognitive health.

“There is growing evidence that physical exercise can benefit cognitive function in middle-aged and older adults, possibly through improved cardio- and cerebro-vascular health,” says Tammy Scott, PhD, a scientist at Tufts’ HNRCA Nutrition and Neurocognition Laboratory.

“THEN AND NOW: The new findings, published in Neurology, used data from the CARDIA (Coronary Artery Risk Development in Young Adults) study, begun in 1985-86. Participants, originally ages 18 to 30, were tested for blood pressure, cholesterol levels and other measures, and also walked at an increasingly fast pace on a treadmill until they couldn’t continue. The young adults could stick with the treadmill test an average of 10 minutes. Continue reading
