Why Understanding Resistance Physiology Matters

Energy restriction is a common strategy in many contexts—health management, athletic preparation, and body composition changes. Understanding the physiological mechanisms by which mechanical loading influences muscle mass and strength during deficit provides a scientific foundation for informed decision-making. These articles present evidence from controlled trials and mechanistic research to illuminate how resistance exercise modulates the metabolic and signalling environment of skeletal muscle.
