Eat less; move more; live longer. It’s never too late to start.
Exercising regularly throughout life is the best way to keep your heart healthy. But starting to exercise even in late middle age may lessen the risk of heart failure, according to a report in the May 15 issue of Circulation. Heart failure, a gradual decline in the heart’s ability to pump enough blood to meet the body’s needs, affects about 6.5 million people in the United States.
The study involved more than 11,000 people who were part of a long-running project begun in the late 1980s, the Atherosclerosis Risk in Communities Study. Every six years, participants got medical testing and filled out questionnaires about their physical activity.
People who followed federal recommendations for physical activity (see How much physical activity do you need?) for the first 12 years of the study had the lowest risk of heart failure—31% lower than people who didn’t exercise at all. But people who increased their physical activity levels starting around age 60 over a period of just six years lowered their risk by 12%.
I hope you enjoy fine tuning as much as I do. Yesterday, we learned about the value of activity coupled with exercise. Today, we look at the significance of how much we exercise.
Participating in exercise 4-5 days per week is necessary to keep your heart young, according to new research published in The Journal of Physiology. These findings could be an important step to develop exercise strategies to slow down such aging.
The optimal amount of exercise required to slow down aging of the heart and blood vessels has long been a matter of vigorous debate. As people age, arteries—which transport blood in and out of the heart—are prone to stiffening, which increases the risk of heart disease. Whilst any form of exercise reduces the overall risk of death from heart problems, this new research shows different sizes of arteries are affected differently by varying amounts of exercise. 2-3 days a week of 30 minutes exercise may be sufficient to minimize stiffening of middle sized arteries, while exercising 4-5 days a week is required to keep the larger central arteries youthful.
The authors performed a cross-sectional examination of 102 people over 60 years old, with a consistently logged lifelong exercise history. Detailed measures of arterial stiffness were collected from all participants, who were then categorized in one of four groups depending on their lifelong exercise history: Sedentary: less than 2 exercise sessions/week; Casual Exercisers: 2-3 exercise sessions per week; Committed Exercisers: 4-5 exercise sessions/week and Masters Athletes: 6-7 exercise sessions per week. (NB: an exercise session was at least 30 minutes). Continue reading
As much as I work on promoting movement – exercise – here, it seems only fair to point out that April is the American Heart Association’s Move More Month.
According to the American Heart Association’s Heart Disease and Stroke Statistics 2018 Update, only 22 percent of American adults meet the federal physical activity recommendations for aerobic and muscle strengthening activity, and one in three adults report participating in no leisure time activity at all!
While most people know exercise should be part of their daily routine, many don’t realize just how easy it is to add physical activity to everyday activities. Not everyone has hours to spend in the gym, or even 30 minutes to take a walk every day. It’s time to help people feel good about what they’re already doing, while also providing some new and creative ways to sneak in even more daily movement. Continue reading
Eat less; move more; live longer. I have been preaching that for the nearly nine-year life of this blog. There are lots of ways that exercise benefits our brains as well as our bodies which I hope will protect me from cognitive damage as I age. When it comes to the trillions of microbes in my gut, however, I confess to pretty much total ignorance. They are there. They do their jobs. We get along fine.
A recent issue of the New York Times, however, had Gretchen Reynolds writing about exercise benefiting our gut microbes in some very interesting ways. Here is a link to the article if you would like to read the full details.
Below is a quote of several paragraphs which I found meaningful.
“Most of these changes were not shared from one person to the next. Everyone’s gut responded uniquely to exercise.
“But there were some similarities, the researchers found. In particular, they noted widespread increases in certain microbes that can help to produce substances called short-chain fatty acids. These fatty acids are believed to aid in reducing inflammation in the gut and the rest of the body. They also work to fight insulin resistance, a precursor to diabetes, and otherwise bolster our metabolisms. Continue reading
Eat less; move more; live longer. Simple acts with profound effects. And, according to the latest study, don’t wait till you are old to start.
Exercise can reverse damage to sedentary, aging hearts and help prevent risk of future heart failure – if it’s enough exercise, and if it’s begun in time, according to a new study by cardiologists at UT Southwestern and Texas Health Resources.
To reap the most benefit, the exercise regimen should begin by late middle age (before age 65), when the heart apparently retains some plasticity and ability to remodel itself, according to the findings by researchers at the Institute for Exercise and Environmental Medicine (IEEM), which is a collaboration between UT Southwestern Medical Center and Texas Health Presbyterian Hospital Dallas.
And the exercise needs to be performed four to five times a week. Two to three times a week was not enough, the researchers found in an earlier study. Continue reading
Each month, the office of Disease Prevention and Health Promotion releases an infographic with the latest data related to a Healthy People 2020 Leading Health Indicator (LHI) topic. These infographics show progress toward Healthy People 2020 LHI targets — and show where there’s still work to be done.
This month’s featured LHI topic is Nutrition, Physical Activity, and Obesity. Check out the infographic below, then head over to the Healthy People 2020 LHI Infographic Gallery to see infographics for other LHI topic areas.
I don’t know how many times I have run across this kind of information, but it never ceases to amaze me – to a large extent – whatever the physical problem – exercise is often the answer. Eat less; move more; live longer really works. Here is what Harvard has to say about exercise in relation to joint pain.
The U.S. Department of Health and Human Services recommends:
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. That really isn’t very much when you break it down.
Joint pain can rob you of life’s simple pleasures — you may no longer look forward to walking your dog, gardening, or chasing a tennis ball across the court. Even the basics of getting through your day, like getting into the car or carrying laundry to the basement, can become sharp reminders of your limitations.
But the right exercises performed properly can be a long-lasting way to subdue ankle, knee, hip, or shoulder pain. Although it might seem that exercise would aggravate aching joints, this is simply not the case. Exercise can actually help to relieve joint pain in multiple ways:
It increases the strength and flexibility of the muscles and connective tissue surrounding the joints. When thigh muscles are stronger, for example, they can help support the knee, thus relieving some of the pressure on that joint.
Exercise relieves stiffness, which itself can be painful. The body is made to move. When not exercised, the tendons, muscles, and ligaments quickly shorten and tense up. But exercise — and stretching afterward — can help reduce stiffness and preserve or extend your range of motion.
It boosts production of synovial fluid, the lubricant inside the joints. Synovial fluid helps to bring oxygen and nutrients into joints. Thus, exercise helps keep your joints “well-oiled.”
It increases production of natural compounds in the body that help tamp down pain. In other words, without exercise, you are more sensitive to every twinge. With it, you have a measure of natural pain protection.
It helps you keep your weight under control, which can help relieve pressure in weight-bearing joints, such as your hips, knees, and ankles.
If all this isn’t enough, consider the following: exercise also enhances the production of natural chemicals in the brain that help boost your mood. You’ll feel happier — in addition to feeling better.

This is a good question in my estimation. It means the person wants to exercise. So, there is at least the beginning of a plan to lose weight, get healthy, build yourself up or something along those lines. This is totally in my wheelhouse of eat less; move more; live longer.
Tufts University offers some excellent guidelines.
“Nobody questions the health benefits of even just a little exercise, but you may wonder about what might be called the “Goldilocks” question: How much physical activity is “just right”? And is it possible to get too much or to overdo the intensity? Two large new studies, both published in JAMA Internal Medicine, attempt to answer such questions and identify the “sweet spot” of the ideal amount of exercise,” according to the Tufts University Health and Nutrition Update.
“Miriam E. Nelson, PhD, associate dean of the Tisch College and a professor in Tufts’ Friedman School, author of the “Strong Women” series of books, served as vice-chair of the committee for the US government’s first-ever Physical Activity Guidelines for Americans in 2008. Those guidelines call for at least:
– 150 minutes per week of moderate activity OR
– 75 minutes per week of vigorous activity OR
– Some equivalent combination. Continue reading
