New research provides insights into how exercise may help to prevent or slow cognitive decline during aging. For the study, investigators assessed the expression of genes in individual cells in the brains of mice. The team found that exercise has a significant impact on gene expression in microglia, the immune cells of the central nervous system that support brain function. Specifically, the group found that exercise reverts the gene expression patterns of aged microglia to patterns seen in young microglia. Treatments that depleted microglia revealed that these cells are required for the stimulatory effects of exercise on the formation of...

Aerobic training is known to regulate blood pressure more effectively when practiced in the evening than in the morning. Researchers who conducted a study of elderly patients concluded that evening exercise is better for blood pressure regulation thanks to improved cardiovascular control by the autonomic nervous system via a mechanism known as baroreflex sensitivity. "There are multiple mechanisms to regulate blood pressure, and although morning training was beneficial, only evening training improved short-term control of blood pressure by enhancing baroreflex sensitivity. This is important because baroreflex control has a positive effect on blood pressure regulation, and there aren't any medications...

It’s the cycle of life. Lifelong bicyclers may live longer, have stronger immune systems and are less likely to experience knee pain or osteoarthritis, than people who don’t ride bikes. Although previous studies have already shown several benefits of cycling, new research now shows that people who cycle regularly have significantly less chance of developing osteoarthritis by the age of 65, according to NPR. The study, which was published last month in Medicine & Science in Sports & Exercise, surveyed 2,600 people with an average age of 64 about their lifetime exercise habits. All of the participants were at an...

Exercise prompts muscles to release molecular cargo that boosts brain cell function and connection, but the process is not well understood. New research has found that the nerves that tell muscles to move also prompt them to release more of the brain-boosting factors. "The molecules released from the muscle go into the bloodstream and then to the brain." said Hyunjoon Kong. "As we get older, we lose these neurons from the muscle," he said. The researchers compared two muscle tissue models—one with neuron innervation and one without. They found that the innervated muscle produced more molecules that promote brain neuron...

Consistently exercising 2–3 times a week over the long term is linked to a lower current risk of insomnia as well as the ability to clock up the recommended 6–9 hours of shut-eye every night, suggests an international 10-year study. The researchers assessed the frequency, duration, and intensity of weekly physical activity and symptoms of insomnia, nightly sleep clocked up, and daytime sleepiness among middle-aged adults. The 4,399 study participants (2,085 men; 2,254 women) were drawn from the European Community Respiratory Health Survey. They had answered questions on the frequency and duration of physical activity at baseline (ECRHS II;1998–2002) and...

PORTLAND, OR — Local Woman Kiera Thompson left her gym frustrated after a few male patrons glanced her way, despite the fact that she had gone there specifically so they would glance her way. "Ugh! I wore my skimpiest workout outfit, put my hair in a high ponytail, and spent the entire time lifting weights right where all the dudes work out, and a few of them, you know, glanced in my direction!" Thompson lamented. "I mean, can't a girl in skin-tight yoga pants and a pretty much non-existent top work out in peace without guys noticing she's practically naked?"...

Several storylines related to the events of January 6 have crumbled under closer scrutiny over the past 10 months: the “fire extinguisher” murder of Officer Brian Sicknick; the notion it was an “armed” insurrection and a grand “conspiracy” concocted by right-wing militias; claims that the building sustained $30 million in damages, and so on. In the meantime, the Biden regime has attempted to cover up key aspects of that day, including the name of the officer who shot and killed Ashli Babbitt, which was only recently revealed. Justice Department lawyers continue to resist the release of 14,000 hours of surveillance...

A trio of medical researchers has found that many men experiencing erectile dysfunction can overcome much of the problem by simply engaging in aerobic exercise. Prior research has shown that many older men experience problems with achieving an erection when they want to have sex. In this new study, the researchers identified that some research has shown that erectile dysfunction is quite often associated with cardiovascular health and associated symptoms such as inflammation and narrowing and/or hardening of the arteries. They also noted that regular aerobic exercise has been shown to reduce symptoms of cardiovascular disease. This made them wonder...

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. The study, published in Atherosclerosis, found that climbing more than five flights of stairs daily could reduce risk of cardiovascular disease by 20%. Atherosclerotic cardiovascular disease (ASCVD) along with coronary artery disease and stroke are the leading causes of morbidity and mortality worldwide. "Short bursts of high-intensity stair climbing are a time-efficient way to improve cardiorespiratory fitness and lipid profile, especially among those unable to achieve the current physical activity recommendations," said...

Those suffering from chronic neck pain can alleviate the symptoms on the way to full recovery if they adopt optimal posture and spinal alignment, according to a study. The study evaluated two widely-used corrective approaches to remedy chronic non-specific neck pain caused by forward head posture (FHP) and CBP rehabilitation and traditional exercise programs. "The CBP technique is a posture-correcting method that depends on stretching the viscous and plastic elements of the longitudinal ligament and intervertebral disks, in addition to effectively stretching the soft tissue through the entire neck area in the direction of normal head and neck postures," the...

An estimated 80% of older adults in the U.S. have high blood pressure. A study found that adding a relatively minimal amount of movement, about 3,000 steps per day, can significantly reduce high blood pressure in older adults. This study sought to determine if older adults with hypertension could receive these benefits by moderately increasing their daily walking, which is one of the easiest and most popular forms of physical activity for this population. The study focused on a group of sedentary older adults between ages 68 and 78 who walked an average of about 4,000 steps per day before...

New research supports the idea that the brains of older adults who maintain physical fitness by engaging in regular strenuous exercise more closely resemble those of younger adults. The researchers used functional MRI to measure fluctuations in blood oxygen level-dependent signals as the 52 study participants performed tasks involving several varieties of cognitive control. The fMRI scans indicated that young adults primarily used the dorsolateral prefrontal cortex—a classical working memory, cognitive control center of the brain that is activated more as tasks became more demanding. In general, the brain calls upon its resources like firefighters respond to a multi-alarm fire:...

What Is Salt? Salt is a seasoning that can flavor food and act as a preservative. It’s about 60% chloride and about 40% sodium. Nearly all unprocessed foods -- think veggies, fruits, nuts, meats, whole grains, and dairy foods -- are low in sodium. The salt that we do eat helps relax and contract muscles, lends a hand with nerve impulses, and balances the minerals and water we take in. How Much Salt Do You Need? Our body needs only a small amount of sodium. We should get about 1,500 milligrams of it every day. But the average American takes...

Good cardiorespiratory fitness when young is associated with up to a 40% lower risk of developing 9 specific cancers later on—at least in men—suggests a large long term study. These include cancers of the head and neck, esophagus, stomach, pancreas, liver, bowel, kidney, and lung. At the start of their stint, when they were aged between 16 and 25, conscripts underwent a standard battery of assessments. The final analysis included more than 1 million men (1,078,000), 84,117 (7%) of whom subsequently developed cancer in at least one site during an average monitoring period of 33 years. Compared with men with...

Static isometric exercises—the sort that involve engaging muscles without movement, such as wall sits and planks—are best for lowering blood pressure, finds a pooled data analysis of the available evidence from clinical trials. In a bid to potentially update information on the best form of exercise for controlling blood pressure, they trawled research databases looking for clinical trials reporting the effects of an exercise training intervention lasting two or more weeks on resting blood pressure. The exercise interventions were classified as aerobic (cardio); dynamic resistance training; a combination of these; HIIT; and isometric exercises. Healthy resting blood pressure was defined...

Neuroscientists have found that intensive exercise could slow the course of Parkinson's disease. The finding could pave the way for new non-drug approaches. The research has identified a new mechanism responsible for the positive effects of exercise on brain plasticity. Professor Paolo Calabresi, said, "We have discovered a never observed mechanism, through which exercise performed in the early stages of the disease induces beneficial effects on movement control that may last over time even after training is suspended." Previous work has shown that intensive physical activity is associated with increased production of a critical growth factor, the brain-derived neurotrophic factor...

Regular physical exercise, such as resistance training, can prevent Alzheimer's disease, or at least delay the appearance of symptoms, and serves as a simple and affordable therapy for Alzheimer's patients. This is the conclusion of an article. During the study, the mice were trained to climb a 110 cm ladder with a slope of 80° and 2 cm between rungs. Loads corresponding to 75%, 90% and 100% of their body weight were attached to their tails. The experiment mimicked certain kinds of resistance training undertaken by humans in fitness centers. At the end of a four-week period of training, blood...

Researchers have long known that moderate exercise has a beneficial impact on the body's response to inflammation, but what's been less understood is why. New research done on a mouse model suggests that the answers may lie at the production level of macrophages—white blood cells responsible for killing off infections, healing injury and otherwise acting as first responders in the body. "Much like if you train your muscles through exercise, we showed that exercise of moderate intensity ended up training the precursors of those macrophages in the bone marrow," says Ali Abdul-Sater. "The way that exercise is doing this is...
