exercise

People often think exercise is mainly about muscles, sweat, and burning calories. But scientists are discovering that exercise may also change the brain in important ways. A new study published in the journal Neuron suggests that the brain continues working hard even after a workout ends, and this extra brain activity may help the body […] The post Your brain keeps working after exercise—and it m…

Scientists in Finland have discovered that listening to personally chosen music during hard exercise may help people continue working out much longer before becoming exhausted. The study found that favorite music improved endurance by nearly 20 percent during high-intensity cycling sessions, offering a surprisingly simple way to improve exercise performance. The findings were published in […] The…

A new study offers clues as to why exercise can improve neurological symptoms in people with multiple sclerosis (MS).

Many people think major physical decline only happens in old age. But a major Swedish study suggests the process may begin much earlier than most people expect. According to researchers who followed people for nearly 50 years, the body’s physical performance often starts gradually declining around age 35. The study also brought encouraging news. Even […] The post Your body may start slowing down …

This interview uncovers how exercise may reduce cancer cell viability, with insights into adipose interactions and innovative 3D culture systems.

Exhausting gym sessions aren’t a must requirement for meaningful muscle growth and strength.

Building muscle doesn’t have to mean exhausting workouts or soreness. Researchers found that slow, controlled “lowering” movements can boost strength more efficiently while requiring less effort. Even five minutes a day of simple exercises like chair squats or wall push-ups can make a real difference. It’s a smarter, easier way to get stronger—no gym required.

The brain is more mechanically connected to the body than previously appreciated, scientists reported in Nature Neuroscience, noting the connection could be a potential biological mechanism underlying why exercise is thought to benefit brain health.

New research suggests that sustained exercise may quietly reshape the biology of stress. In a first-of-its-kind clinical trial published in the Journal of Sport and Health Science, researchers explored how a year of aerobic exercise affects the biology of stress and emotion. The randomized study focused on long-term physiological changes linked to regular physical activity. [...]

By tracking healthy adults over 12 months, researchers found that regular cardiovascular workouts lead to a drop in systemic cortisol. This reduction suggests physical activity provides a biological buffer against chronic stress.

In exercise and workout for the purpose of losing weight. Isn't it that the glycogen in the liver takes 20 hours to deplete. Must one deplete glycogen storage first before fat burning in cells would be utilized? But I read conflicting reports that even without depleting glycogen storage, fats... Read more

Nature, Published online: 17 April 2026; doi:10.1038/d41586-026-01245-w Study in mice suggests that B cells help regulate muscle performance.

Many people underestimate the importance of sleep, thinking it is simply a time when the body shuts down. In reality, sleep is a highly active process that keeps the body healthy. A new study from the University of California, Berkeley, published in Cell, reveals how the brain controls growth hormone during sleep and why this […] The post Deep sleep could help build muscle, burn fat, and boost br…

Musculature, strength, size, and endurance are maintained only so long as they are demanded. The moment that demand disappears, the physiological mechanisms that once built muscle now work towards energy conservation, initiating a gradual, though measurable, decline

Scientific study has extensively corroborated the advantageous impacts of exercise on mood, cognitive function, and stress resilience. Nonetheless, the fundamental biological mechanisms underpinning these effects have yet to be thoroughly integrated. This review advocates for and substantiates an integrated model focused on the “Exercise-Gut Microbiome-Short-Chain Fatty Acids (SCFAs)-Brain Functi…

Researchers have identified a molecular mechanism that helps explain why exercise remains so effective in maintaining muscle health with age. Scientists have identified a molecular switch that may help explain one of the biggest benefits of exercise as people grow older: the ability to keep muscles repairing themselves. A research team at Duke-NUS Medical School, [...]

Scientists are investigating how exercise-triggered stress reshapes the cell’s energy systems, and whether those same mechanisms could eventually help counter metabolic disease. Don’t like the gym? Exercise scientist Ryan Montalvo gets it. He still goes anyway, because the physical strain of exercise often leads to lasting health benefits. Although workouts can feel intimidating, exercise trigger…

Endurance improvements from exercise depend on sustained activation of specific brain neurons after workouts. Exercise does more than build stronger muscles. It also reshapes activity in the brain. In a study published in the Cell Press journal Neuron, scientists report that the long-term boost in endurance from repeated workouts, such as being able to run [...]

Feeding mice with hyperglycemia a high-fat, low-carbohydrate diet lowered their blood sugar and improved their bodies’ response to exercise.

A new study suggests that when blood sugar is elevated, exercise alone may not be enough. Most of us hear the same advice: move more, eat less fat. Exercise can trim body fat, build muscle, and strengthen the heart. It also raises cardiorespiratory fitness, which is often tracked by how well the body can deliver [...]
