Comparative transcriptome analysis of fast twitch muscle and slow twitch muscle in Takifugu rubripes
Comparative Biochemistry and Physiology Part D: Genomics and Proteomics, 2017Fast twitch muscle and slow twitch muscle are two important organs of Takifugu rubripes. Both tissues are of ectodermic origin, and the differences between the two muscle fibers reflect the differences in their myofibril protein composition and molecular structure.

Slowing of fast-twitch muscle in the dystrophic mouse
Experimental Neurology, 1981Abstract Isometric twitch tension was measured in fast-twitch and slow-twitch muscles of normal and dystrophic ( C57Bl 6J dy 2J dy 2J ) mice in vivo. In dystrophic mice more than 6 months old the fast-twitch extensor digitorum longus (EDL) showed a prolongation of the time to peak tension as well as the time to relax to one-half ...

Proteomic analysis of slow‐ and fast‐twitch skeletal muscles
PROTEOMICS, 2005Abstract Skeletal muscles are composed of slow‐ and fast‐twitch muscle fibers, which have high potential in aerobic and anaerobic ATP production, respectively. To investigate the molecular basis of the difference in their functions, we examined protein profiles of skeletal muscles using sodium dodecyl sulfate‐polyacrylamide gel ...

Clues to calcineurin function in mammalian fast-twitch muscle
Journal of Muscle Research & Cell Motility, 2001It is believed that brief, high amplitude Ca2+ transients, as found in fast-twitch muscles, are not sufficient to activate the calcineurin (Cn)-dependent signaling pathway involved in regulation of slow myosin and slow sarcoplasmic reticulum Ca2+-ATPase genes (Olson and Williams, Cell 101: 689-692, 2000).

Enzymatic changes in hypertrophied fast-twitch skeletal muscle
Pfl�gers Archiv European Journal of Physiology, 1976Fast-twitch plantaris muscles of female rats were subjected to unilateral compensatory overload, induced by partial excision of synergistic muscles. One group of rats remained sedentary whereas another was subjected to a supplemental program of treadmill exercise consisting of walking 3 m/min, 65% grade, 2 h/day, 5 days/week.

Shortening heat in slow- and fast-twitch muscles of the rat
American Journal of Physiology-Cell Physiology, 1996Shortening heat has been reported in several amphibian skeletal muscles. In this investigation, shortening heat has been investigated in both soleus and extensor digitorum longus (EDL) muscles of young rats. The procedure involved shortening the muscles through two different distances, at near maximum velocity and at the onset of a summated twitch ...

Biochemical properties of overloaded fast-twitch skeletal muscle
Journal of Applied Physiology, 1982Previous studies suggest that fast-twitch skeletal muscle overloaded by surgical removal of synergists contains a greater percent of slow-twitch fibers than normal muscle. Therefore we examined subcellular systems known to represent biochemical properties of slow-twitch skeletal muscle by measuring myosin ATPase, Ca2+ regulation of myofibril ATPase ...

Influence of electrical stimulation on a fast-twitch muscle in aging rats
Journal of Applied Physiology, 1991Recently we observed that the flexor digitorum longus muscle of the Fischer 344 rat, which is comprised primarily of type IIb muscle, does not change in size, fiber type, or physiological characteristics during senescence [Am. J. Physiol. 258 (Cell Physiol. 27): C1031-C1035, 1990].

Effect of aging on the buffering capacity of fast-twitch skeletal muscle
Mechanisms of Ageing and Development, 1991The effects of aging on the in situ buffering capacity of fast-twitch muscle fibers was examined in the tibialis anterior (TA) and extensor digitorum longus (EDL) muscles of specific pathogen free Fischer 344 rats. Muscles were electrically stimulated with trains of impulses lasting 100 ms at a frequency of 80 Hz.

Temperature sensitivity of tension development in a fast‐twitch muscle of the rat
Muscle & Nerve, 1984AbstractIsometric contractions of the biceps brachii (short head) muscle in the rat were recorded in vitro with direct stimulation and at different temperatures (range, 35°C–10°C). In confirmation of our previous findings from fast extensor digitorum longus and slow soleus muscles, the time and rate parameters of the twitch and the tetanus showed an ...
