A reader who happens to be in the business of health, Velocity Athletic Training Radio, enjoys my blog and asked me if I would like to discuss it with her on the radio. You remember radio, don’t you? If you would like to hear it click the link below.
Eat less; move more; live longer. It’s never too late to start exercising according to researchers at Wake Forest Baptist Medical Center
Moderate-intensity exercise can help even extremely obese older adults improve their ability to perform common daily activities and remain independent.
Even this fat cat can benefit …
Findings from the National Institutes of Health-funded study are published in the July issue of the journal Obesity.
In the United States, obesity affects nearly 13 million adults age 65 and older. Both overall obesity and abdominal obesity are strongly associated with the development of major mobility disability (MMD), the inability to walk a quarter of a mile, according to the study’s lead author, Stephen Kritchevsky, Ph.D., director of the Sticht Center for Healthy Aging and Alzheimer’s Prevention at Wake Forest Baptist.
Previous data on older populations had suggested that obesity may lessen the beneficial effects of physical activity on mobility. However, this research, which analyzed data from the multicenter Lifestyle Interventions and Independence for Elders (LIFE) study, showed that a structured physical activity program reduced the risk of MMD even in older adults with extreme obesity.
Experts in aging and Alzheimer’s disease are conducting a national clinical study to determine if exercise may be an effective non-drug intervention for maintaining cognitive fitness.
The Rush Alzheimer’s Disease Center at Rush University Medical Center is the only site in Illinois, and one of only 15 sites across the United States leading the Exercise in Adults With Mild Memory Problems (EXERT) study, which is trying to determine if exercise can slow the progress of memory loss and cognitive impairment in older adults.
Neuroscientists are collaborating with the YMCA to provide individualized, one-on-one exercise programs and personal training to study participants. Rush will be working with the McGaw YMCA in Evanston, Illinois, to provide 45-minute personal training sessions for one year.
Adults with memory issues may avoid being active when they need it most
“We want to see if a personalized program implemented in the community and prescribed by health care providers can be an effective therapy for people with memory issues,” said Dr. Neelum Aggarwal, associate professor of neurology and principal investigator of the EXERT study at Rush.

One of the stated aims of this blog is to live past 100. Posts every day touch on that goal, but mostly in a ‘part of the big picture’ way. Herewith some positive ideas from Harvard Health publications directly on the subject of super-aging.
Finding role models who are older than we are gets more difficult as we age. But in the last few years, medical science has identified a new group we can aspire to join — the super-agers. The term refers to people in their 70s and 80s who have the mental or physical capability of their decades-younger counterparts.
Although super-agers’ brains show less cell loss than those of their contemporaries, their IQs and educational levels are similar. What sets them apart might be that they view problem-solving differently, Dr. Dickerson says. “They may approach these tasks as a challenge they can succeed at, in contrast to typical older adults who may give up.” Continue reading
Having written tons about the physical benefits of exercise, it seems timely to mention the emotional ones, too.
Please also check out my Page Important facts about your brain (and exercise benefits),
If you would like more detail on items above, please check out the following posts:
Certainly one of the best concepts I have learned in producing this blog is that the brain benefits from exercise. It is the first item on the infographic above – Stay Active. I have written a Page on it – Important facts about your brain (and exercise benefits.)
Regarding the “Don’t be Salty” entry, it is important to keep in mind that most of the damaging salt we consume comes in the form of processed foods. Pay attention to the salt/sodium content in the foods you consume.
Stress damages us in many ways. I have written about it numerous times. You can search S T R E S S in the tags for more. One of the best posts on it is: Super tools for handling stress that I wrote in 2011. Check it out.
Last, but not least, ‘Be happy.’ I have covered the benefits of happiness in lots of posts. I think my Page – Positive psychology – What’s it all about? will also prove valuable information.
Moderate-intensity exercise can help improve your thinking and memory in just six months.
Happy days! More positive information on the benefits to the brain garnered from physical exercise! This time from Harvard Medical School.
You probably already know that exercising is necessary to preserve muscle strength, keep your heart strong, maintain a healthy body weight, and stave off chronic diseases such as diabetes. But exercise can also help boost your thinking skills. “There’s a lot of science behind this,” says Dr. Scott McGinnis, an instructor in neurology at Harvard Medical School. Continue reading
As a senior citizen, I am aware of the aging process going on in both my body and my brain. I exercise to help preserve both. Here are some super suggestions from Harvard HEALTHbeat on bolstering the memory aspect of your brain.
Your daily habits and lifestyle — what you eat and drink, whether you exercise, how stressed you are, and more — affect your mental health every bit as much as your physical health. A growing body of research indicates that regular exercise and a healthful diet can help protect your memory from aging-related decline. Continue reading
The Defense Advanced Research Projects Agency (DARPA) is working with seven U.S. universities and elements of the Air Force and Army on research that seeks to stimulate the brain in a non-invasive way to speed up learning.
DARPA announced the Targeted Neuroplasticity Training, or TNT, program last March, and work now has begun on the effort to discover the safest and most effective ways to activate a natural process called “synaptic plasticity.”
Plasticity is the brain’s ability to strengthen or weaken its neural connections to adapt to changes in the environment. For TNT Program Manager Dr. Doug Weber, such plasticity is about learning.
“We’re talking about neural plasticity, or how the neurons, which are the working units in the brain, how their function changes over time as we train on new skills,” he said during a recent interview with Department of Defense News.
Targeted Neuroplasticity Training
TNT research focuses on a specific kind of learning called cognitive skills training. People use cognitive skills to do things like pay attention, process information, do several things at once, detect and understand patterns, remember instructions, organize information and much more.

Eat less; move more; live longer is the mantra of this blog. Of course the most important element in living longer is having a fully functioning brain. The BBC just filed a wonderful story supporting that outcome.
Doing moderate exercise several times a week is the best way to keep the mind sharp if you’re over 50, research suggests.
Thinking and memory skills were most improved when people exercised the heart and muscles on a regular basis, a review of 39 studies found.
This remained true in those who already showed signs of cognitive decline.
Taking up exercise at any age was worthwhile for the mind and body, the Australian researchers said.
Exercises such as T’ai Chi were recommended for people over the age of 50 who couldn’t manage other more challenging forms of exercise, the study in the British Journal of Sports Medicine said.
Eat less; move more; live longer is the mantra of this blog. Seems that a healthy lifestyle increases the chances of a healthy brain as we age, according to the Mayo Clinic.
Adopting a healthy lifestyle can protect the brain against several risk factors for Alzheimer’s disease, Mayo Clinic research shows. Controlling blood pressure and cholesterol and avoiding obesity, smoking and diabetes are among the steps that can help preserve brain health, according to the study, published in JAMA Neurology.
Neurologists believe two aspects make up Alzheimer’s disease:
- Amyloid deposits: Toxic proteins that build up plaques on the brain.
- Neurodegeneration: Loss of structure and function of neurons in the brain.
The Mayo research examined whether the risk factors and protective steps against each differ. Continue reading
Thought you would appreciate this April first infographic from the National Institutes of Health. So, here is something good from the government that doesn’t cost us anything. Enjoy!
The split between mind and body seems clearest in the realm of exercise. Each is good for us, but is one better?
Professor Sam Wang, Ph.D. Molecular Molecular Biology and Neuroscience, Princeton University covers the subject extensively in Lecture 23 of his course The Neuroscience of Everyday Life which I took from The Great Courses.
Opinion has been split on the subject.
“It is exercise alone that supports the spirits and keeps the mind in vigor.” – Marcus Tullius Cicero – 65 BC.
“Exercise invigorates and enlivens all the faculties of body and mind…. It spreads a gladness and a satisfaction over our minds and qualifies us for every sort of business, and every sort of pleasure.” – John Adams, Second President of the U.S.
On the other hand, that curmudgeon, Mark Twain said, “I take my only exercise acting as pallbearer at the funeral of my friends who exercise regularly.”
The business of brain-training is a multi-million dollar operation. It includes software and games we can play on our computers, Nintendo, smart phones as well as specialized machines. Also, there are the puzzles, like Sudoku, crosswords and other pattern recognition games.
There is a ton of good information in this. Read it and reap!

Our Better Health
Anxiety seems to be a near-universal condition. In the United States alone, approximately 40 million adults – or 18 percent of the population – suffer from an anxiety disorder.
And these numbers represent only the diagnosed (i.e. reported). The actual number is likely to be significantly higher.
The truth is that society is somewhat to blame (not to negate our own sense of responsibility.) We’ve managed to build a 24/7 “constantly connected” infrastructure that has permeated into schools, businesses and elsewhere. Many people are under constant pressure to succeed; most ironically by leveraging this very infrastructure. This only exacerbates the problem.
“Prevention is the best cure” is a universal axiom within the medical community, including within the mental health sphere. Understanding what “triggers” certain symptoms or condition can – in some instances – drastically reduce the likelihood of a symptom or episode.
Here, we focus on ten established “triggers” that…

Eat less; move more; live longer is the mantra of this blog. I am always thrilled to run across studies that underscore those concepts. This one adds nutritional supplementation for additional benefits.
A study of the combined effect of exercise and nutrition intervention on muscle mass and function in seniors finds that exercise has a positive impact, with some possible additive effect of dietary supplementation.
Although sarcopenia, progressive muscle loss, is a natural part of aging, it is generally identified when muscle mass and muscle function falls below defined thresholds. Sarcopenia’s impact can be enormous as it affects mobility, balance, risk of falls and fractures, and overall ability to perform tasks of daily living. Given the aging of populations worldwide, public health and clinical recommendations to prevent and manage sarcopenia are urgently needed.
The new systematic review ‘Nutrition and Physical Activity in the Prevention and Treatment of Sarcopenia’  summarizes the results of randomized controlled trials (RCTs) assessing the effect of interventions combining physical activity and dietary supplements on muscle mass and muscle function in subjects aged 60 years and older.

Mayo Clinic researchers have uncovered three new agents to add to the emerging repertoire of drugs that aim to delay the onset of aging by targeting senescent cells – cells that contribute to frailty and other age-related conditions. A recent study of human cell cultures shows that the drugs, fisetin and two BCL-XL inhibitors – A1331852 and A1155463 – cleared senescent cells in vitro. Findings appear online in Aging.
“Senescent cells accumulate with age and at sites of multiple chronic conditions, such as in fat tissue in diabetes, the lungs in chronic pulmonary diseases, the aorta in vascular disease, or the joints in osteoarthritis,” says James Kirkland, M.D., Ph.D., director of the Robert and Arlene Kogod Center on Aging. “At Mayo Clinic, we discovered the first senolytic drugs – agents that selectively eliminate senescent cells while leaving normal cells unaffected. These senolytic agents alleviated a range of age- and disease-related problems in mice. We used the hypothesis-driven approach that we used to discover the first senolytic drugs, two published in early 2015 and another later in 2015, to discover these three new senolytic drugs.” Continue reading
