The effect of breed and body weight at slaughter on histochemical muscle fiber characteristics and meat quality of longissimus lumborum and semitendinosus lamb muscles [PDF]
Archives Animal Breeding, 2023 The skeletal muscles of mammals are composed of fibers of different morphological, metabolic and functional characteristics. The properties of muscle fibers may be determined genetically as well as by environmental factors such as the age of the animals,

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 ...

Modeling and simulation of excitation- contraction coupling of fast-twitch skeletal muscle fibers [PDF]
Technology and Health Care, 2020 BACKGROUND: The current excitation-contraction coupling model of fast-twitch skeletal muscle fibers cannot completely simulate the excitation-contraction process. OBJECTIVE: To solve this problem, this study proposes an excitation ...

Possibility of uncoupling protein 1 expression in bovine fast-twitch muscle fibers
Journal of Veterinary Medical Science, 2023 Uncoupling protein 1 (UCP1) is responsible for non-shivering thermogenesis in brown/beige adipocytes in humans and rodents. Previously, we showed unexpected expression of UCP1 in bovine skeletal muscles. Here we evaluated Ucp1 mRNA levels in the muscle tissue of Japanese Black steers.

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.
