Physical activities like a daily, 20-minute walk may help reduce disparities in heart health – AHA

Hearts are kept strong with regular physical activity, and daily activity such as a daily, 20-minute, brisk walk is key; however, some groups may have additional barriers that affect whether or not a daily walk is feasible. Increasing physical activity levels, particularly among people at higher risk for cardiovascular disease, has known heart health benefits and may help reduce cardiovascular health disparities, according to a new American Heart Association scientific statement published today in the Association’s flagship, peer-reviewed journal Circulation. An American Heart Association scientific statement is an expert analysis of current research and may inform future guidelines.

The new statement, “Increasing Equity of Physical Activity Promotion for Optimal Cardiovascular Health in Adults,” examines physical activity levels among different groups of adults, reviews strategies for increasing physical activity in groups that are under-resourced or at-risk for poor cardiovascular health, and offers suggestions for how to promote physical activity to reduce cardiovascular risk equitably through physical activity.

“Helping everybody improve their heart health is important,” said Gerald J. Jerome, Ph.D., FAHA, volunteer chair of the writing committee for the scientific statement and a professor in the department of kinesiology at Towson University in Towson, Maryland. “We found that many groups who had poor heart health also had low levels of physical activity. We know regular physical activity is a key component of optimal heart health. These findings provide an opportunity to focus our efforts on physical activity programs in places where people need them the most.”

Can exercise lower the risk of developing Parkinson’s disease?

Getting regular exercise such as cycling, walking, gardening, cleaning and participating in sports may decrease the risk of developing Parkinson’s disease, according to new research published in the May 17, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study found female participants who exercised the most had a 25% lower rate of Parkinson’s disease when compared to those who exercised the least. The study does not prove that exercise lowers the risk of developing Parkinson’s disease. It only shows an association.

“Exercise is a low-cost way to improve health overall, so our study sought to determine if it may be linked to a lower risk of developing Parkinson’s disease, a debilitating disease that has no cure,” said study author Alexis Elbaz, MD, PhD, of the Inserm Research Center in Paris, France. “Our results provide evidence for planning interventions to prevent Parkinson’s disease.”

The study included 95,354 female participants, mostly teachers, with an average age of 49 who did not have Parkinson’s disease at the start of the study. Researchers followed participants for three decades during which 1,074 participants developed Parkinson’s disease.

Over the course of the study, participants completed up to six questionnaires about the types and amounts of physical activity they were getting. They were asked how far they walked and how many flights of stairs they climbed daily, how many hours they spent on household activities as well as how much time they spent doing moderate recreational activities such as gardening and more vigorous activities such as sports.

Researchers assigned each activity a score based on the metabolic equivalent of a task (METs), a way to quantify energy expenditure. For each activity, METs were multiplied by their frequency and duration to obtain a physical activity score of METs-hours per week. For example, a more intense form of exercise like cycling was six METs, while less intense forms of exercise such as walking and cleaning were three METs. The average physical activity level for participants was 45 METs-hours per week at the start of the study.

Further on walking …

I have written about the benefits of walking for more than 10 years, calling it the ‘Cinderella’ of the exercise spectrum, completely unappreciated. Now comes the Wall Street Journal with a wonderful article on more favorable aspects of walking.

if you are concerned about weight loss and calorie-burning:

Intensifying your fitness routine could come from the simplest change possible: how you put one foot in front of the other.

Walking with more intensity can burn as many calories as higher-impact activities such as running or even HIIT classes, experts say. That could mean incorporating weights, hills, intervals or a faster pace without breaking into a jog.

What about walking faster:

Speed up those steps and research suggests you can boost longevity. Plus, you can get the same—if not greater—calorie burn on a 20-minute walk where you incorporate intervals at a brisk pace as you would from a 40-minute walk at a leisurely pace, Dr. Allison says.

” …for those looking to lose weight: Along with making healthy diet choices, you need to increase the intensity of your exercise. If jogging or running is uncomfortable on your joints, Dr. Allison suggests power walking, where you swing your arms, and race walking, where one foot remains in contact with the ground at all times.

But speed isn’t the only way to up the ante through walking:

Incorporating hills into your walking routine is a low-impact way to challenge the muscles and heart more, says Abrea Wooten, senior national education manager for gym company Life Time Inc. Ms. Wooten walks uphill wearing a weighted vest on a treadmill to help train for ultramarathons. “It’s so much gentler on my joints,” she says. “The incline puts less stress on the knees.”

Daily 11 minute brisk walk enough to reduce risk of early death – Cambridge

One in ten early deaths could be prevented if everyone managed at least half the recommended level of physical activity, say a team led by researchers at the University of Cambridge.

In a study published today in the British Journal of Sports Medicine, the researchers say that 11 minutes a day (75 minutes a week) of moderate-intensity physical activity – such as a brisk walk – would be sufficient to lower the risk of diseases such as heart disease, stroke and a number of cancers.

Cardiovascular diseases – such as heart disease and stroke – are the leading cause of death globally, responsible for 17.9 million deaths per year in 2019, while cancers were responsible for 9.6 million deaths in 2017. Physical activity – particularly when it is moderate-intensity – is known to reduce the risk of cardiovascular disease and cancer, and the NHS recommends that adults do at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity activity a week.

To explore the amount of physical activity necessary to have a beneficial impact on several chronic diseases and premature death, researchers from the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge carried out a systematic review and meta-analysis, pooling and analyzing cohort data from all of the published evidence. This approach allowed them to bring together studies that on their own did not provide sufficient evidence and sometimes disagreed with each other to provide more robust conclusions.

In total, they looked at results reported in 196 peer-reviewed articles, covering more than 30 million participants from 94 large study cohorts, to produce the largest analysis to date of the association between physical activity levels and risk of heart disease, cancer, and early death.

US neighborhood walkability influences physical activity, BMI levels – BU

A new study led by Boston University School of Public Health found that people in highly walkable neighborhoods were more likely to engage in adequate physical activity.

For the first time, a study examined perceived neighborhood walkability, physical activity, and obesity indicators on a national level, finding that people who lived in walkable neighborhoods were more likely to be physically active and have lower BMIs—but this association differed among Black, Hispanic, and Asian populations.

Three out of four adults do not meet the recommended levels of physical activity, which the US Centers for Disease Control and Prevention defines as at least 150 minutes of moderate activity or 75 minutes of vigorous activity each week. As obesity and related chronic conditions such as cardiovascular disease, and diabetes continue to rise in the US, a new study led by a Boston University School of Public Health (BUSPH) researcher is examining how neighborhood walkability may influence physical activity and obesity rates.

Octogenarians should walk 10 minutes a day to prolong life

I realize that writing about 80-year-olds and above is ‘rarified atmosphere,’ but I loved the fact that walking was still a tangible benefit to the person. You can never hear enough about the benefits of exercise or the damage of being sedentary.

One hour of walking per week is associated with greater longevity in people aged 85 years and above, according to research presented at ESC Congress 2022.

Regardless of age, adults are advised to do at least 150 minutes a week of moderate intensity activity or 75 minutes a week of vigorous intensity activity, or an equivalent combination.2 However, in adults, sedentary time tends to increase with age while the amount of physical activity declines.

Walking at uncomfortable pace may improve mobility may help folks with PAD – AHA

People with a condition that restricts blood flow to the legs and feet may be able to improve their long-term walking ability by walking for exercise at a pace that feels painful or uncomfortable, new research suggests.

The study, published Wednesday in the Journal of the American Heart Association, found people with peripheral arterial disease, or PAD, who walked at a speed that caused painful symptoms increased their walking speed and leg function more than those who walked for exercise at a more comfortable pace.

“We were surprised by the results because walking for exercise at a pace that induces pain in the legs among people with PAD has been thought to be associated with damage to leg muscles,” senior study author Dr. Mary McDermott said in a news release. She is a professor of medicine and preventive medicine at Northwestern University’s Feinberg School of Medicine in Chicago.

“Exercise that induces leg pain is beneficial, though difficult,” she said. “We now are working to identify interventions that can make the higher intensity exercise easier – and still beneficial – for people with PAD.”

An estimated 8 to 10 million U.S. adults have PAD, a condition characterized by reduced blood and oxygen flow stemming from a narrowing of the arteries that take blood from the heart to the rest of the body. The condition typically affects the legs and feet, causing symptoms during walking such as cramping, weakness, fatigue, aching, and pain or discomfort that fade within 10 minutes after resting.

Aging slows down walking speed – What you need to know to improve

I have a Page on the benefits of walking as well as numerous posts on various aspects of the subject. I have called it numerous times, “The Cinderella of the Exercise World” because it is so unappreciated. The following is from the Optimal Aging Portal of McMaster University.

Walking speed (gait speed) or mobility is necessary for most tasks that humans undertake. Slowing of walking speed is associated with aging in all persons. Walking speed has also been associated both with how long a person will live (survival) and with changes that occur when older persons are having difficulty or become unable to do tasks. In research studies walking ability has been assessed by tests where persons are either asked to walk at their usual speed (sometimes called self-selected walking speed) OR fast walking speed where a person is instructed to walk as fast as they can safely.

How fast do I need to walk to cross the road safely?

To undertake various activities within the community that involve walking, the average distances required to walk vary from 200-600 metres. The task that usually concerns older persons most in relation to walking speed is how quickly they need to walk in order to cross a road safely. The critical speed cited for this task is 1.14 meters/second and has been broken down in the following way:

  • Crossing a 2 lane road (4 metres/lane) in 10 seconds (5 seconds per lane),
  • And 3 seconds to get up and down off either curb (1.5 seconds per curb).
  • The critical speed is 8 metres/7 seconds = 1.14meters/second.

The speed we are able to walk decreases as we age. There are several reports that indicate some normal ranges for older persons. For example, general walking speeds for community activities are 1.2-1.4 metres/sec until 80 years and 1.0-1.8 metres/second until 90 years and older.

Older persons who have a walking speed of less than 1 metre/second have reported ceasing involvement in any regular physical activity. Self-selected walking speed associated with frailty has been reported as less than 0.65 metres/second if you are short (i.e. = 159cm) and 0.75m/sec if you are taller (height >159cm).

Walk this way – or any way – to better health

For the record, I have written about the benefits of walking numerous times here. You can check out my Page – Why you should walk more.

National Walking Day is Wednesday, April 6, 2022. Established by the American Heart Association and celebrated on the first Wednesday in April, National Walking Day is a day take a walk, move, dance…do whatever works to get you moving and help you kick-off a commitment to a lifetime of healthy living.

The American Heart Association cites research showing the health benefits of regular walking and the importance of safe walking spaces in communities

Researchers provide insight into how the brain multitasks while walking

New research turns the old idiom about not being able to walk and chew gum on its head. Scientists with the Del Monte Institute for Neuroscience at the University of Rochester have shown that the healthy brain is able to multitask while walking without sacrificing how either activity is accomplished.

“This research shows us that the brain is flexible and can take on additional burdens,” said David Richardson, an MD/PhD student in his fifth year in the Pathology & Cell Biology of Disease Program, and first author of the study recently published in the journal NeuroImage. “Our findings showed that the walking patterns of the participants improved when they performed a cognitive task at the same time, suggesting they were actually more stable while walking and performing the task than when they were solely focused on walking.”

Exercise, Not Just Sudoku for Seniors

Grampa, when you finish that puzzle please slip on your walking shoes and step outside.

A lot of senior citizens are doing Sudoku puzzles and crosswords to ‘exercise their brains’ and slow the aging process. These puzzles can be fun, and they do build puzzle-solving skills which are long-lasting. They are not even half the battle against aging, though.

14601014695_dd8c815c39_o

“Unless the activities that you’re practicing span a broad spectrum of abilities, then there is not a proven general benefit to these mental fitness programs. So, the idea that any single brain exercise program late in life can act as a quick fix for general mental function is almost entirely faith-based,” Professor Wang said in our post on physical exercise vs mental exercise.

Walking, on the other hand, boosts blood flow to the brain. Medicine.net reported that moderate aerobic exercise helps boost blood flow to the brain.

More on 10,000 steps a day …

Back in August I addressed the concept of ‘10,000 steps a day.’ You can read about it here. Now comes the American Heart Association with further insights into this idea. I have said repeatedly that walking is the Cinderella of the exercise world – totally unappreciated.

Photo by Andrea Piacquadio on Pexels.com

It’s a worthy, healthy goal to take 10,000 steps each day, but that magic number didn’t come from doctors or physical trainers.

In the mid-1960s, Japanese marketers trying to sell a pedometer named it manpo-kei, which generally translates to “10,000 step meter” in English. The Japanese character for “10,000” roughly resembles a person walking.

“It’s a nice clean number and it makes a good marketing message,” said Amanda Paluch, assistant professor in the School of Public Health and Health Sciences at the University of Massachusetts in Amherst. “You can see why it stuck. But there was not a lot of science behind it.”

What about 10,000 steps a day?

I have written numerous times that I consider walking to be the Cinderella of the exercise world because there is so little appreciation of it. Possibly, also, because it is a lovely quiet exercise that doesn’t take a lot of exertion despite engaging many of the body’s muscles as well as actually bearing your total body weight. There is an entire Page of posts I have written on walking – Why you should walk more.

Possibly one of the most widely spread ideas about walking is that a person should try to take 10,000 steps a day. What about that?

Well, Harvard’s T.H. Chan School of Public Health has something to say about that.

Do I really need to take 10,000 steps a day?

“You’ve probably heard that moving 10,000 steps a day is a healthy goal. Some apps and pedometers have 10,000 steps earmarked, so that when you reach it, a congratulations screen dings or vibrates. Not a simple goal as many of us sit more than stand, thanks to driving cars, sitting at office desks, and reclining in chairs at home; in fact the average number of daily steps an American takes is closer to 4,800. [21] It may surprise you that the benchmark number of 10,000 is not actually based on science but was created as a marketing tactic in the 1960s by a company making pedometers.

“So is there any science to support stepping it up? Generally, research finds that more steps are better but even a lower amount can achieve health benefits. A study following 4,840 men and women 40 years of age and older for about 10 years found that those taking at least 8,000 steps daily had a 51% lower death rate from all causes compared with those taking 4,000 steps or fewer. [20] A large cohort of more than 16,000 older American women (mean age 72 years) from the Women’s Health Study followed for 4 years found that those taking 4,400 steps a day had a 41% lower death rate compared with those taking about 2,700 steps a day. [21] Death rates continued to drop in relation to taking more steps up to 7,500 daily, but steps beyond that did not show additional benefit.

“Although these studies confirm that taking more steps is good, the exact amount to see a health benefit will vary among individuals. The guideline from the Centers for Disease Control and Prevention to “move more and sit less throughout the day; some physical activity is better than none” remains an appropriate goal for everyone. [2] There’s nothing wrong with aiming for 10,000 steps or even higher, except when it becomes so daunting that you lose motivation, or you feel discouraged that a lesser amount is not good enough. Rather than feeling chained to a specific step count, listen to your body, challenge it, and feel good about what it can accomplish.”

Stretching more effective than walking to lower high blood pressure: Study

A new University of Saskatchewan (USask) study has found that stretching is superior to brisk walking for reducing blood pressure in people with high blood pressure or who are at risk of developing elevated blood pressure levels.

Walking has long been the prescription of choice for physicians trying to help their patients bring down their blood pressure. High blood pressure (hypertension) is a leading risk factor for cardiovascular disease and among the top preventable risk factors affecting overall mortality.

This new finding, published December 18, 2020 in the Journal of Physical Activity and Health, shows that stretching should be part of a well-rounded treatment plan for people wrestling with hypertension.

“Everyone thinks that stretching is just about stretching your muscles,” said kinesiology professor Dr. Phil Chilibeck (PhD), a co-author of the study. “But when you stretch your muscles, you’re also stretching all the blood vessels that feed into the muscle, including all the arteries. If you reduce the stiffness in your arteries, there’s less resistance to blood flow,” he said, noting that resistance to blood flow increases blood pressure.

Walking: Key To Staying Active and Independent – Tufts

Some years ago, I described walking as the Cinderella of the exercise world – totally unappreciated. Thankfully, more and more people are stepping up and stepping out. Here is what the Tufts Health & Nutrition Letter has to say about walking.

Did you get your 10,000 steps today? Many people have adopted this daily walking goal to obtain the recommended amount of physical activity. The 10,000-steps-a-day number comes from the Japanese brand name of a pedometer manufactured in the 1960s, the “10,000 steps meter.” In the Fitbit era, counting daily steps remains appealing to many people as a source of motivation.

Photo by Zen Chung on Pexels.com

In the US, adults are urged to get the equivalent of 150 minutes per week of moderate intensity exercise. Walking is a popular way to meet those recommendations, particularly in older adults or people who are relatively physically inactive.

Although 10,000 steps is a worthy challenge, aiming for more exercise than you normally get—unless you are one of the few who regularly trains for marathons or triathlons—comes with benefits. Any amount or type of physical activity adds to your daily goal. Regularly taking the stairs instead of the elevator, or parking farther away from your destination, can make a measurable improvement in your health.
