Eat less; move more; live longer remains the mantra of this blog. So, I was thrilled to read this latest from the Mayo Clinic on High Intensity Interval Training (HIIT).
Everyone knows that exercise is good for you, but what type of training helps most, especially when you’re older – say over 65? A Mayo Clinic study says it’s high-intensity aerobic exercise, which can reverse some cellular aspects of aging. The findings appear in Cell Metabolism.
Mayo researchers compared high-intensity interval training, resistance training and combined training. All training types improved lean body mass and insulin sensitivity, but only high-intensity and combined training improved aerobic capacity and mitochondrial function for skeletal muscle. Decline in mitochondrial content and function are common in older adults. Continue reading
I would like to thank reader, Garry, for tipping me off to this study on Parkinson’s disease and exercise.
From an analysis of more than 3,400 patients with Parkinson’s disease, researchers found that those who engaged in a minimum of 150 minutes of physical activity a week experienced much slower declines in health-related quality of life (HRQL) and mobility over 2 years, compared with patients who exercised less than 150 minutes weekly.
Note: This recommendation exactly equals that of the U.S. Dept of Health and Human Services. Which states: Adults 18 to 64 should get:
2.5 hours/wk of moderate intensity exercise.
OR 1.25 hours a week of vigorous aerobic physical activity
Or Some combination of the above – equivalent episodes of at least 10 minutes spread throughout the week. Continue reading
At the risk or appearing like I am selling out on my idea of protecting my brain by exercising regularly, I would like to suggest this fun pastime as an additional line of defense against cognitive impairment.
I wrote this for another blog I write occasionally and thought it would be of interest to you. I know a lot of folks are doing adult coloring books these days for relaxation. I thought these puzzles would be a nice step up that could be more challenging to the imagination.
I ran across these at an art fair years ago. They are wonderful brightly colored shapes that you get to remake into various geometric visions. You can see more at the website of Kadon Enterprises, Inc. Kadon says that the creation of tiling patterns is an ancient and still very popular art form and recreation. “In quilting designs, floor tiles and wallpaper patterns, we find geometric shapes that fit together in attractive, usually symmetrical arrangements.”
There is a wonderful brochure that comes with each puzzle that explains some of the relationships between the angles and gets into the math of it.
Although I have only pictured two, I hope you can see how multi-faceted this is. I spend many happy hours exploring this and many of their other puzzles.
I used these two shots so you could see the simplest variation. The tiles are acrylic and fit into place perfectly.

Just two days ago I posted on older men being at risk of osteoporosis. “As I reported here, after the age of 50 men are as likely to get osteoporosis as prostate cancer. More to the point, older people of both sexes have great vulnerability to it.”
Now comes a new study that explains how weight-bearing exercises affect our bone structure and fight that disease.
Osteoporosis affects more than 200 million people worldwide and is a serious public health concern, according to the National Osteoporosis Foundation. Now, Pamela Hinton, associate professor in the Department of Nutrition and Exercise Physiology, has published the first study in men to show that long-term, weight-bearing exercises decrease sclerostin, a protein made in the bone, and increase IGF-1, a hormone associated with bone growth. These changes promote bone formation, increasing bone density. Continue reading
What we put into our system counts a lot toward our daily health and ultimate longevity. So, I thought this study on increasing seniors drinking was relevant.
Most older Americans drink alcohol. Given that this segment of the population is projected to almost double by 2050, reaching 112 million, in the future, there will likely be many more older drinkers in the United States than currently. Importantly, older individuals are more sensitive to alcohol’s effects than their younger counterparts, and are also more likely to take prescription medications that can interact negatively with alcohol, potentially leading to falls and other injuries. This study examined trends in drinking status among U.S. adults 60 years of age and older.
Researchers analyzed data from the 1997-2014 National Health Interview Surveys: 65,303 respondents 60 years of age and older (31,803 men, 33,500 women) were current drinkers; 6,570 men and 1,737 women were binge drinkers. Analysis of respondents by sex, age group, and birth cohort showed differing trends over time. Continue reading
Because three out of four cases of osteoporosis are women, most people consider it a women’s disease, especially men. However, as I reported here, after the age of 50 men are as likely to get osteoporosis as prostate cancer. More to the point, older people of both sexes have great vulnerability to it.
Here’s what Harvard Health Publications has to say:
Don’t think men need to worry about osteoporosis? Think again. In fact, about one in four men older than 50 will break a bone due to osteoporosis during their lifetime, according to the National Osteoporosis Foundation.
How can men protect themselves and lower their risk of osteoporosis? Here are some strategies: Continue reading
Because arthritis sufferers experience pain when they move, many conclude that not moving is healthier because it doesn’t hurt. Unfortunately, that is one instance where listening to your body is not the best course of action. I hope the following information will alter that conclusion.
First, some startling statistics on arthritis from Ashley Boynes.
Some 50 million Americans have doctor-diagnosed arthritis. That’s 22 per cent of the population, more than 1-in-5 adults!
Arthritis costs the US economy $128 BILLION per year.
Sad statistic – 31 per cent of US 18-64 year olds with arthritis either can’t work, or report work limitations.
Arthritis is the number one MOST COMMON disability.
Some 32 percent of veterans surveyed in 36 States had been diagnosed with arthritis, compared with 22 percent of non-veterans, representing a 50 per cent increased risk for arthritis for veterans.
More than 1,000,000 joints will be replaced this year alone.
To answer the question about suitability of exercising with arthritis, I recently attended a Northwestern Memorial Hospital Healthy Transitions presentation on Arthritis and Exercise.
I turned 77 in January and while I generally enjoy what I consider to be robust good health, I nonetheless occupy an old and aging body. Sometimes I miss stuff people say, particularly when there is background noise.
“Could you repeat that?” The reason you may have to say something twice when talking to older family members may not be because of their hearing. Researchers at the University of Maryland (UMD) have determined that something is going on in the brains of typical older adults that causes them to struggle to follow speech amidst background noise, even when their hearing would be considered normal on a clinical assessment.
In an interdisciplinary study published by the Journal of Neurophysiology, researchers Samira Anderson, Jonathan Z. Simon, and Alessandro Presacco found that adults aged 61–73 with normal hearing scored significantly worse on speech understanding in noisy environments than adults aged 18–30 with normal hearing. The researchers are all associated with the UMD’s Brain and Behavior Initiative. Continue reading
I think sleep may be the most under-appreciated aspect of living a healthy life. Diet and exercise and well-known if not often followed, but sleep is often thought of as an intrusion in our busy lives. I know that back when I was in the working world, I certainly thought of it that way.
Scientific data suggests that all animals probably do sleep—including the most unexpected creatures, such as fish, birds, worms, and flies. Sara Aton, University of Michigan ssistant professor in the Department of Molecular, Cellular, and Developmental Biology, can attest to dozing cats, mice, and even cuttlefish, all of which she’s studied as they snoozed. She marvels that biologists once thought bugs and birds and worms never slept.
“I think there’s this pervasive misconception that your brain is just turning off when you go to sleep, because there’s no obvious output. Outside of a coma, you can’t think of a less interesting behavior to study than sleep, right?” Aton says. “Sleep is something that, as humans, we spend a third of our life doing. And yet biologists and the neuroscience community didn’t have a lot of interest in it.” (my emphasis)
But now that we know better, new questions arise: Do animals all rest for the same reasons?
After studying sleep for the past decade, Aton is convinced that it matters—a lot. “I’m much more protective of, for example, my son’s sleep than I would have been had I not been in this field,” she says.
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
I have been retired for 17 years, since I turned 60, and my health has improved dramatically since then. I have lost around 20 pounds and I exercise regularly. I must confess that I got careless the first few years. There’s a dangerous ‘freedom’ you experience when you first retire that takes some getting used to. It turns out that I’m not the only one to encounter that situation.
Healthy lifestyle adherence among retired, late middle-aged adults may be more challenging than originally thought. New research, from West Virginia University,
published this week in the Journal of the American Board of Family Medicine, sought to compare the rates of healthy lifestyle adherence among retired, late middle-aged adults to those who were still working. Continue reading
At the risk of sounding repetitious, eat less; move more; live longer. As a 77-year old who rides his bike daily, this kind of info is music to my ears.
Older adults with higher levels of physical activity have pain modulation patterns that might help lower their risk of developing chronic pain, reports a study in PAIN®, the official publication of the International Association for the Study of Pain (IASP). The journal is published by Wolters Kluwer.
In tests of pain processing by the central nervous system, physically active older adults have lower pain perception and are better able to block responses to painful stimuli, according to the new research by Kelly M. Naugle, PhD, and colleagues of Indiana University–Purdue University Indianapolis. “This study provides the first objective evidence suggesting that physical activity behavior is related to the functioning of the endogenous pain modulatory systems in older adults,” the researchers write.
Being More Active, Less Sedentary, Affects Pain Perceptions in Older Adults
I have written about osteoporosis numerous times as it attacks us in our latter years for the most part. Also, women seem more vulnerable to it than men.
I ran across the following in my web wanderings. Guys, this is relevant to all the women in our lives, wives, mothers, relatives, so please check it out.
Estrogen therapy has already been credited with helping women manage an array of menopause-related issues, including reducing hot flashes, improving heart health and bone density, and maintaining levels of sexual satisfaction.
Now a new study
suggests that the same estrogen therapy used to treat osteoporosis can actually lead to healthier teeth and gums. The study outcomes were published online in
Menopause, the journal of The North American Menopause Society (NAMS).
Sleep is one of the truly under-appreciated aspects of living a long and healthy life. I know for sure that when I was in the working world, I pretty much considered sleep to be an imposition on my busy life.
Times, and my mind, have changed. Please check out my Page – How important is a good night’s sleep for more on this crucial aspect of our daily lives.
Living a healthy life is simple but not easy. This infographic from the National Institute on Aging makes it very clear.
