Muscle vs Fat: The Body Type Linked to Slower Brain Aging MRI research suggests a higher muscle-to-visceral-fat ratio may keep the brain biologically younger. Here’s what the findings mean for long-term brain health.

🧠 More muscle + less hidden belly fat linked to younger-looking brains. Big implications for aging + metabolic health.

Meet Dr Hila Barzilai-Tutsch, postdoc at ARMI, Monash in the Currie Group, studying how muscle regenerates after trauma or disease. Her work explores the cellular and molecular mechanisms that restore shape and function. 🧬💪

Most people are clueless that amino acids are the REAL game-changers for muscle growth and recovery. Without them, muscle growth stalls, recovery slows, and energy fades. 💪

Human skeletal muscle fiber heterogeneity beyond myosin heavy chains | Nature Communications Skeletal muscle is a heterogenous tissue comprised primarily of myofibers, commonly classified into three fiber types in humans: one “slow” (type 1) and two “fast” (type 2A and type 2X). However, heterogeneity between and within traditional fiber types remains underexplored. We applied transcriptomic and proteomic workflows to 1050 and 1038 single myofibers from human vastus lateralis, respectively. Proteomics was conducted in males, while transcriptomics included ten males and two females. We identify metabolic, ribosomal, and cell junction proteins, in addition to myosin heavy chain isoforms, as sources of multi-dimensional variation between myofibers. Furthermore, whilst slow and fast fiber clusters are identified, our data suggests that type 2X fibers are not phenotypically distinct to other fast fibers. Moreover, myosin heavy chain-based classifications do not adequately describe the phenotype of myofibers in nemaline myopathy. Overall, our data indicates that myofiber heterogenei

After a long process, I will soon have a paper out at PNAS that explores the molecular mechanisms of residual force enhancement using some cool mouse models and small-angle Xray diffraction. It is not just about titin-based forces, per se, but they run the show 😎. Details OTW #titin #MuscleScience
