How Muscle Contractions Signal the Brain: The Myokine Pathway Explained
Skeletal muscle releases signalling molecules called myokines that travel through the bloodstream to regulate learning, memory, and brain inflammation. Different…
Resistance Training Protects Brain Health Through Vascular and Cognitive Pathways, New Evidence Shows
Resistance training influences brain health through endothelial function, neurotrophic signalling, blood-brain barrier integrity, and inflammation control, according to 2025 research.…
Exercise’s True Power: A Systematic Review Shows Mitochondrial Remodeling, Not Just Volume, Drives Fitness Gains
A systematic review analyzing 425 human studies shows that training intensity—not duration—is the primary driver of mitochondrial expansion, with high-intensity…
Bones as Metabolic Organs: How Mechanical Loading Triggers Glucose Control
Bones are metabolic organs, not merely structural tissue. Mechanical loading triggers osteocalcin release, which improves insulin sensitivity and glucose regulation…
Exercise Intensity, Effort, and Physiological Stress: A Framework for Understanding Training Zones
Exercise intensity spans a continuous physiological spectrum integrating objective metrics (1RM percentage, VO₂max, lactate thresholds) with subjective effort scales (RPE,…
Post-exercise brain signal may be key to fitness gains, mouse study suggests
Researchers at Jackson Laboratory and University of Pennsylvania identified brain neurons that appear necessary for endurance training to produce fitness…
High-Carbohydrate Breakfast Fails to Boost Glycogen in Well-Trained Cyclists
A new study found that a large carbohydrate breakfast did not increase liver or muscle glycogen in trained cyclists, suggesting…
How Exercise Rebalances Muscle Aging at the Cellular Level
Exercise suppresses DEAF1, a transcription factor that becomes overactive with age and drives excessive muscle protein synthesis while impairing cellular…
