Published on Leave a comment on Walking Helps Prevent Low Back Pain Episodes

Great news for individuals with lower back pain. Which is a lot of us. A recent study found that the simple act of walking helps  with prevention of low back pain episodes!

In the study, persons who had recently recovered from an episode of lower back pain were randomly assigned either to 1) an individualized and progressive walking intervention, along with 6 sessions with a physical therapist over a 6 month period (to discuss the walking) or to 2) a no treatment control group. Afterwards, the walking group took an a median of 208 days until their next activity-limiting episode of lower back pain, while the control (no walking) group took a median of 112 days.

In other words, walking regularly resulted in going twice as long until the next occurrence of low back pain compared to non-walkers. They also had fewer occurrences of activity limiting low back pain episodes. Note that these were individuals (43 to 66 years) who had a history of low back pain episodes

How much did they walk? The walkers kept a walking diary, with the median 80 minutes of walking in week 1, which increased to 130 minutes by week 12. They walked a median of 3 times in week one, which increased to 4 times in week 12.

Published on Leave a comment on Improve Fitness To Lower Risk of Prostate Cancer

A recent large Swedish study found that men who increased their cardiorespiratory fitness had a  significantly lower prostate cancer risk (when compared to men whose cardiorespiratory fitness stayed the same or declined) .

Men who increased their fitness by more than 3% over the course of a year had a 35% lower risk of prostate cancer during the 7 year follow-up. Cardiorespiratory fitness was measured two times (baseline and a year later) by peddling on a stationary cycle and measuring absolute and relative VO2 max - the amount (volume) of oxygen the body uses while exercising as hard as possible.

By the way, other studies also find that cardiorespiratory fitness is associated with the risk of some cancers, as well as dying from certain cancer types. This study did not find an increase in cancer deaths, but it also only followed the men 7 years.

Bottom line: Increase your activity levels! Walking, hiking, bicycling gardening, sports, exercises - it all counts. You can do it!

Published on Leave a comment on Try Exercise First For Erectile Dysfunction

Erectile dysfunction is a serious problem for many men, especially as they get older. A review and analysis of 11 well-done studies  looking at whether exercise helps with erectile dysfunction found that YES, it does.

They found that exercising for at least 30 minutes three times a week can be just as effective as Viagra and Cialis at improving erectile dysfunction (ED). Also, the worse the ED at the start of a study, the more exercise helped.

What were the exercises? Any aerobic activities that got the heart pumping, such as cycling, tennis, or brisk walking. In the studies looked at, the exercise sessions were typically 30 to 60 minutes, and occurred 3 to 5 times a week. Some studies had the men exercise on their own, while other studies had the men attend supervised exercise sessions.

Bottom line: Exercise improved ED in all men! It didn't matter what the men weighed, their medication use - it helped them all. (Examples of earlier studies looking at exercise and physical activity helping improve ED.)

This could be because ED is considered a measure of a man's overall heart health. When there is heart disease, inflammation, and narrowing or hardening of the arteries - then ED increases. Physical activity, on the other hand, improves health, including heart disease.

Published on Leave a comment on Daily Walking Up Stairs Lowers the Risk of Heart Disease

We've known for a while that exercise and physical activity lower the risk of developing heart disease. It turns out that a good exercise that many of us do in the course of ordinary life is walking up and down stairs. Yes, that counts!

A large study (458,860 adults) used data from the UK (Biobank). They found that walking up 5 flights of stairs (about 50 steps) daily was associated with a 20% lower risk of developing heart disease (including ischemic strokes) after 5 years.

Interestingly, persons who were stair climbers at the beginning of the study, but then stopped at some point during the 5 year length of the study had a higher risk of heart disease than those who never climbed stairs.

Bottom line: Walk up stairs whenever you can. It's good for your heart!

From Science Daily: Walking more than five flights of stairs a day can cut risk of heart disease by 20 percent, study says

Forget walking 10,000 steps a day. Taking at least 50 steps climbing stairs each day could significantly slash your risk of heart disease, according to a new study from Tulane University. ...continue reading "Daily Walking Up Stairs Lowers the Risk of Heart Disease"

Published on Leave a comment on Some Habits For Living A Longer and Healthier Life

There is tremendous interest in how to live a long and healthy life. This means trying to avoid getting diseases that so many suffer from as they age, such as diabetes, heart disease, and dementia. What diets are best? What kind of lifestyle?

NPR published a recent article about 7 daily habits linked to living a longer, healthier life, using information from Dan Buettner's work on blue zones. Scientific research supports the importance of these habits, especially good nutrition (for example, the Mediterranean diet) and physical activity.

The blue zones are communities throughout the world in which there are a lot of centenarians (people living to 100 years or more). What is important is that the people in these communities are aging with good health, and leading active and fulfilling lives - without dementia, and not in nursing homes.

The diets vary from place to place, but all avoid fast foods and highly processed foods. Instead, a lot of vegetables, fruits, whole grains, legumes (beans), and nuts are eaten. Little meat. Food is cooked at home. By the way, this type of diet is associated with a good gut microbiome, and generally a good gut microbiome goes with good health.

Unfortunately, these blue zone areas are now fading, due to changes in lifestyles  - fast food, etc. But a few other places are stepping up, trying to make living spaces healthier and incorporating what has been learned about health and longevity - for example, Singapore.

Bottom line: Research shows a diet rich in plant-based foods (whole grains, fruits, vegetables, nuts, seeds, legumes), plenty of sleep, lots of movement (physical activity), and a sense of purpose in life are all important in aging well.

Excerpts from correspondent Allison Aubrey article at NPR: 7 habits to live a healthier life, inspired by the world's longest-lived communities

At a time when life expectancy in the U.S. has dipped and diet-related disease is a leading cause of death, it's no wonder that Dan Buettner's decades-long exploration of centenarians who thrive in the longest-lived communities on Earth is attracting lots of attention. ...continue reading "Some Habits For Living A Longer and Healthier Life"

Published on Leave a comment on Documentary About Healthy Aging and Living Longer

There has been tremendous interest in the past decade over the best diet and lifestyle for aging well and living to a ripe old age. Author Dan Buettner has spent much of the past decade visiting communities around the world where there are many residents who live to 100 years or more, and in good health. He calls these communities blue zones.

Dan Buettner now has a good National Geographic documentary on Netflix called Live to 100: Secrets of the Blue Zones. This documents him visiting Blue Zones (Ikaria, Greece; Okinawa, Japan; Sardinia, Italy; Loma Linda, Calif.; and Nicoya Peninsula, Costa Rica) looking at the lifestyles and diets in this communities.

He found that while the diets vary, overall the people in these communities have a lot of plant based whole foods (especially whole grains, vegetables, beans, and tubers, such as sweet potatoes), and they avoid fast-food and highly processed foods. They do not take dietary supplements. They have a lot of physical activity in their daily activities, are committed to their families, take time to de-stress, and they have social networks with healthy behaviors.

He also recently published a book called The Blue Zones Secrets for Living Longer: Lessons From the Healthiest Places On Earth.

Published on Leave a comment on Being Physical Fit Is Linked To A Lower Risk of Atrial Fibrillation and Stroke

A recent large study found another great reason for being physically active. The researchers found that physical fitness is linked to  atrial fibrillation (AFib) and stroke.

Atrial fibrillation is a heart rhythm disorder, and having it is linked to a much higher risk of having a stroke. The researchers found that being physically fit (exercise! physical activity!) is linked to lower rates of atrial fibrillation, stroke, and MACE (major adverse cardiovascular events, such as stroke or heart attack leading to death).

There was an eleven year follow up of the approximately 15,450 participants, all of whom did not have atrial fibrillation at the start of the study. The study tested the  physical fitness of the participants (average age 55 years) on an exercise treadmill.

Bottom line: Physical activity and physical fitness are important for reducing the risk of developing heart problems, including atrial fibrillation. Yes, even taking walks (brisk is best) will improve physical fitness.

From Science Daily: Keep fit to avoid heart rhythm disorder and stroke

A study in more than 15,000 people has found that physical fitness is linked with a lower likelihood of developing atrial fibrillation and stroke. The research is presented at ESC Congress 2023.

Published on Leave a comment on Short Bursts of Physical Activity Associated With Lower Cancer Risk

Great news for people who don't have the time or the desire to engage in exercise routines, gym visits, or sports. A recent large study found that several very short bursts of physical activity (each less than a minute or two) during the day are beneficial to health. They lower cancer risk!

Researchers followed 22,398 non-exercising adults (average age 62 years) for 7 years. The participants wore tracking devices (wrist accelerometers) for 1 week at the beginning of the study to measure their activity levels. Starting at year 2 their cancer incidence was looked at.

They found that several short bursts of vigorous physical activity (each lasting less than 1 or 2 minutes) each day was associated with lower rates of cancer. And it was a dose response - the more of these little bursts of physical activity over the day, the lower the rates of cancer, especially physical activity related cancer.

About 3 1/2 minutes a day of vigorous activity was associated with a 17 to 18% reduction in cancer risk, but 4 1/2 minutes a day was associated with a 31% to 32% reduction in physical activity-related cancers (e.g., breast, endometrial, and colon cancers).

Bottom line: Engage in a little huffing and puffing physical activity every day and lower your risk of cancer. Run up those stairs! Dance to a song! Carry those heavy groceries! Every bit counts. This could be because short bursts of physical activity improve cardiorespiratory fitness and lower inflammation.

Excerpts from Science Daily: Short bursts of daily activity linked to reduced cancer risk

Promising new research suggests a total of just 4.5 minutes of vigorous activity that makes you huff and puff during daily tasks could reduce the risk of some cancers by up to 32 percent. ...continue reading "Short Bursts of Physical Activity Associated With Lower Cancer Risk"

Published on Leave a comment on New Non-Surgical Approach to ACL Rupture Looks Promising

Could this be another paradigm shift in medical care? This time it's substituting a non-surgical approach vs the current surgical approach for ACL ruptures.

A recent study found that a non-surgical bracing procedure for anterior cruciate ligament (ACL) ruptures of the knee resulted in 90% having evidence of ACL healing at 3 months. And those with more healing at 3 months had better long-term (12 month) outcomes.

Those with less severe ACL ruptures had quicker, better healing, and a greater percentage (92%) returned to their pre-injury sport. But 64% were able to return to their sport even if they had a more severe ACL rupture. Eleven patients (14%) reinjured their ACL within a year.

The Cross Bracing Protocol (CBP) used in this study of 80 patients (within 4 weeks of ACL rupture) was: 1) knee immobilization at 90° flexion in a brace for 4 weeks, 2) followed by progressive increases in range-of-motion until the brace was removed at 12 weeks, and 3) physiotherapist-supervised goal-oriented rehabilitation.

The researchers hypothesized that holding the knee at 90 degrees could help unite the torn ends of the ACL and encourage healing. Of course, more and larger studies are now needed to confirm the results.

A new non-surgical bracing treatment may help to facilitate healing after an anterior cruciate ligament (ACL) rupture, a new study has found. ...continue reading "New Non-Surgical Approach to ACL Rupture Looks Promising"

Published on Leave a comment on Outside Walks May Have More Brain Health Benefits Than Inside Walks

Another study was just published with results that may motivate us to go outside more. A small study with college students found that taking a walk outside in nature results in more mental health benefits (improved brain functioning) than taking the same length walk inside.

The walks were short - only 15 minutes long, and yet there were differences in health benefits. This was seen in the brain EEGs done during tasks before and after the walks. One health result which benefited more from outdoor walks is in how the brain functions, which the researchers call cognitive function.

Keep in mind: All exercise has health benefits, including for the brain - whether the exercise/physical activity is done indoors or outdoors. Exercise or physical activity is always better than no exercise or physical activity.

Other studies also show that exercising outdoors in natural environments produces more benefits to the brain than exercising indoors. Outdoor exercise enhances "executive functions" of the brain (such as attention, memory, and control of inhibitions) more than indoor exercise.

Bottom line: Get out and take a walk, even if only for a brief time. It's good for you!

From Medical Xpress: Going for a walk outside found to have more mental health benefits than walking indoors

A team of researchers at the University of Victoria, working with a colleague from York University, both in Canada, has found that going for a short walk outdoors provides people with more mental health benefits than going for a same-length walk inside. In their study, published in the journal Scientific Reports, the group asked volunteers to walk indoors or outdoors and tested them before and after their walk. ...continue reading "Outside Walks May Have More Brain Health Benefits Than Inside Walks"
