Increasing muscle strength is good, but increasing muscle power may be even better for enjoying a longer life, according to a recent study.
Professor Claudio Gil Araújo, who is the director of research and education at Exercise Medicine Clinic — CLINIMEX in Rio de Janeiro, Brazil, led the new study.
Muscle power differs from muscle strength in that it relies on generating force and velocity while coordinating movement. For example, lifting a weight one time requires strength, but lifting it several times as quickly as possible requires power.
Researchers are finding new evidence that exercise — even low-intensity, casual physical activity — can boost brain health in the short- and long-term.
Evidence that exercise can benefit the brain and help maintain cognitive function — including memory — is accumulating.
One study, for instance, suggests that engaging even in low-level phyisical activities, such as doing household chores, can help reduce the risk of cognitive impairment in older adults.
Now, a team led by Michelle Voss — from the University of Iowa in Iowa City — has found evidence in support of the notion that the benefits of just one workout can predict the benefits of frequent physical activity in the long run.
New research suggests that adults over the age of 40 who engage in leisurely physical activity — such as dancing, gardening, or going for a walk — for even a short amount of time each week may have a lower risk of death from multiple causes.
Previous research has shown that engaging even in low-level physical activity — including leisurely tasks, such as gardening — may help protect brain health and cardiovascular health, among other benefits.
Now, a recent observational study, working with tens of thousands of people aged 40 and over has found a link between a lower risk of death from different causes and low levels of physical activity.
Walking the dog can be great exercise for seniors, but there could be one downside: bone fractures.
Fractures suffered by elderly Americans while walking their dogs have more than doubled in recent years, new research shows.
Still, taking your dog for a walk can also bring big health rewards, one joint specialist said.
“Pets can provide companionship for older adults, and the physical exercise from regularly walking a dog may improve other aspects of physical and psychological health,” said Dr. Matthew Hepinstall, who wasn’t involved in the new study.
People who have chronic inflammation in middle-age may develop problems with thinking and memory in the decades leading up to old age, according to a new study published in the February 13, 2019, online issue of Neurology®, the medical journal of the American Academy of Neurology.
There are two kinds of inflammation. Acute inflammation happens when the body’s immune response jumps into action to fight off infection or an injury. It is localized, short-term and part of a healthy immune system. Chronic inflammation is not considered healthy. It is a low-grade inflammation that lingers for months or even years throughout the body. It can be caused by autoimmune disorders like rheumatoid arthritis or multiple sclerosis, physical stress or other causes. Symptoms of chronic inflammation include joint pain or stiffness, digestive problems and fatigue.
Ways to reduce chronic inflammation include getting regular exercise, following an anti-inflammatory heart healthy diet, and getting enough sleep.
IT’S SOMETIMES CALLED “window-shopper’s disease.” As walking brings on leg cramps and pain, people with peripheral artery disease must frequently stop for breaks. When they rest, pain subsides. When they resume walking, PAD pain kicks back in.
PAD is common among older adults. About one in every 20 Americans over age 50 has PAD, with up to 12 million people affected overall, according to the National Heart, Lung, and Blood Institute.
People may mistakenly believe painful walking is part of normal aging. However, PAD is linked to higher risks of cardiovascular complications such as heart attacks or strokes. PAD shouldn’t be suffered stoically or in silence. If you have symptoms, you need a medical evaluation.
In a new study involving people over 70 who have exercised regularly for years, scientists discovered that the participants’ hearts, lungs, and muscles were in equivalent shape to those of people in their 40s.
Researchers from the Human Performance Laboratory at Ball State University in Muncie, IN recently assessed the physical condition of people in their 70s who have been exercising regularly for decades.
The team compared the health measurements of these participants with those of their more sedentary peers and with the measurements of healthy people in their 20s.
To boost their reasoning skills and the brain’s processing speed, seniors may need to exercise for 52 hours over a period of 6 months, concludes a new study. The good news is that low-intensity exercise such as walking has the same benefits — as long as it’s carried out for this length of time.
As more and more research keeps pointing out, exercise does wonders for our brain.
For instance, a recent study that Medical News Today reported on shows that running protects our memory from the harmful effects of stress.
The after-effects of a stroke can be life changing. Paralysis, speech problems and memory loss occur in varying degrees of severity, depending on the location and amount of brain tissue damage. How far a stroke patient can recover is largely determined by the ability of the brain to reorganise itself. Understanding what can improve this ability is therefore essential in developing the best therapies for rehabilitation.
Voluntary physical exercise is known to have a positive effect on a person’s overall well-being. It delays memory loss in old age and improves cognitive ability. A new study, published in the open-access journal Frontiers in Aging Neuroscience, has linked the positive effects of exercise on the brains of mice to their better recovery after a stroke.
Higher levels of total physical activity are strongly associated with lower risk of five common chronic diseases — breast and bowel cancer, diabetes, heart disease and stroke, finds a study in The BMJ.
Many studies have shown the health benefits of physical activity. This has led the World Health Organization (WHO) to recommend a minimum total physical activity level of 600 metabolic equivalent (MET) minutes a week across different ‘domains’ of daily life.
This can include being more physically active at work, engaging more in domestic activities such as housework and gardening, and/or engaging in active transportation such as walking and cycling.
