Skeletal Fiber Type in Muscle Pain and Dysfunction [PDF]
BiomedicinesDifferent types of skeletal muscle fibers display marked heterogeneity in metabolic, mechanical, and regenerative properties. However, their role in chronic musculoskeletal pain remains insufficiently integrated into clinical models.

Characterization of Fiber-Type Composition and Phosphoproteins of Fast- and Slow-Growing Broilers [PDF]
AnimalsMuscle fibers exhibit high plasticity: both the fast-twitch fiber type and slow-twitch fiber type can mutually transform under the regulation of phosphorylation.

Differential Energy Metabolism in Skeletal Muscle Tissues of Yili Horses Based on Targeted Metabolomics and Transcriptomics Analysis [PDF]
BiologySkeletal muscle is the largest organ system in mammals. To investigate the differences in energy metabolism across various skeletal muscles in Yili horses, this study examined muscle fiber type distributions through immunohistochemical staining of ...

Mitochondrial dynamics define muscle fiber type by modulating cellular metabolic pathways
Cell Reports, 2023 Summary: Skeletal muscle is highly developed after birth, consisting of glycolytic fast-twitch and oxidative slow-twitch fibers; however, the mechanisms of fiber-type-specific differentiation are poorly understood.

Effect of resistance training mainly depends on mechanical activation of fast-twitch fiber
Journal of Physical Fitness and Sports Medicine, 2022 This study conducted a secondary survey based on the hypothesis that the “total mechanical activation of fast-twitch fibers in the muscles determines the effects of muscle hypertrophy”, with resistance training of the knee extensor muscles as the target ...

Life, 2023 The ratio of fast- and slow-twitch fibers in human skeletal muscle is variable and largely determined by genetic factors. In this study, we investigated the contribution of microRNA (miRNA) in skeletal muscle fiber type composition.

Skeletal muscle and fiber type-specific intramyocellular lipid accumulation in obese mice
Biomolecules & Biomedicine, 2021 In obesity, accumulation of lipid droplets in skeletal muscle fibers and a shift towards fast muscle fiber types can both contribute to insulin resistance.

Cycling Cross-Bridges Contribute to Thin Filament Activation in Human Slow-Twitch Fibers
Frontiers in Physiology, 2020 It has been shown that not only calcium but also strong binding myosin heads contribute to thin filament activation in isometrically contracting animal fast-twitch and cardiac muscle preparations. This behavior has not been studied in human muscle fibers
