Explore the evidence-based scientific mechanisms governing muscle preservation during caloric deficit.
This collection of evidence-based articles explores the physiological mechanisms, signalling pathways, and research outcomes related to skeletal muscle during energy restriction and mechanical loading.
Examine the molecular mechanisms of the mechanistic target of rapamycin complex 1 pathway and how mechanical loading activates anabolic signalling during caloric deficit.
Read the detailed physiological explanationUnderstand the ubiquitin-proteasome system, autophagy pathways, and the FoxO/atrogin-1/MuRF1 cascade that drives protein degradation in energy deficit.
Learn more about the evidenceInvestigate how Type I and Type II muscle fibres respond differently to combined resistance training and energy restriction, with particular focus on Type II preservation.
Explore resistance exercise researchExplore the mechanisms by which mechanical loading enhances protein synthesis rates and sensitivity during hypocaloric states, including data on MPS responses.
Continue to related muscle physiology topicsAnalyse the synergistic effects of mechanical stimulus and protein intake on muscle protein synthesis and the preservation of muscle mass during energy deficit.
Read the detailed physiological explanationReview controlled trial data and longitudinal findings on muscle mass, strength, and body composition changes with combined resistance training and energy restriction.
Learn more about the evidenceEnergy 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.
