Betaine Mimics Exercise to Slow Aging: New Discovery
What the discovery means for aging research A newly identified molecule, betaine, is shedding light on how regular physical activity translates into tangible anti-aging benefits. While most people know exercise improves heart health and endurance, researchers are now unraveling a deeper biochemical mechanism: betaine acts as a signal that coordinates the body’s response to sustained…

Betaine: A Molecule That Mimics Exercise to Slow Aging
What is betaine and why does it matter? Betaine is a small, naturally occurring molecule found in foods such as beets and spinach. The body also makes betaine on its own. In a new wave of aging research, scientists have identified betaine as a crucial signaling molecule that helps the body coordinate the lasting anti-aging…

Gentle Physical Activity May Help Manage the Brain’s Fatigue: New Insights from Brighton
Rethinking Fatigue: More than a Simple Tiredness Fatigue affects about one in four people at some point, often in the context of chronic illness or long-term health challenges. While pain can sometimes be eased with medication, fatigue is a more elusive symptom. It isn’t merely a lack of energy; it’s a protective signal from the…

Second Round of Exercise Boosts Muscle Growth in Mice, Study Finds
Overview: A Surprising Twist in Muscle Memory A new study from the University of Illinois Urbana-Champaign suggests that a second round of exercise after a short break can trigger greater muscle growth than a first round. In mice that freely ran on an exercise wheel for four weeks, paused for four weeks, and then ran…

Second round of exercise boosts muscle growth in mice
New study shows a second exercise bout can boost muscle growth in mice A new study published in the American Journal of Physiology: Cell Physiology reports that mice who voluntarily ran on an exercise wheel for four weeks, paused for four weeks, and then ran again for another four weeks gained more muscle than those…

Muscle memory in action: a second exercise round boosts mouse growth
Muscle memory in action: a second exercise round boosts muscle growth A new study in mice suggests that a second bout of voluntary wheel running, after a four-week pause, can provoke greater muscle growth than the initial training. The research, published in the American Journal of Physiology: Cell Physiology, found that the second round led…
