...Adrian Lai; Anthony G. Schache; Yi-Chung Lin; Marcus G. Pandy The human ankle plantar-flexors, the soleus and gastrocnemius, utilize tendon elastic strain energy to reduce muscle fiber work and optimize contractile conditions during running. However, studies to date have considered only slow...

... of aerobic metabolic processes has revealed that the extreme diffusion distances between mitochondria found in some muscle fibers do not necessarily limit the rates of aerobic processes per se , as long as the metabolic process is sufficiently slow. However, skeletal muscle fibers from a variety of animals...

..., as these animals grow, their muscle fibers greatly exceed the surface area to volume ratio and intracellular diffusion distance limits of most cells. Previous studies have shown that arginine phosphate (AP) recovery in the anaerobic (light) fibers, which demonstrate a fiber size dependence on anaerobic processes...

..., such that small crabs have fiber diameters that are typical of most cells (<60 μm) while in adult animals the fibers are giant (>600 μm). Thus, as the animals grow, their muscle fibers cross and greatly exceed the surface area to volume ratio( SA : V ) and intracellular diffusion distance threshold...

... by feedback control. The maximum tetanic force, 368±57 kN/m 2 ( N =10), was not significantly different from that recorded in frog muscle fibers at equal temperature. However, the rising phase of the tetanus was considerably slower in the mammalian fibers, 202±20 ms ( N =17) being required to reach 90...

...L. K. Johnson; R. M. Dillaman; D. M. Gay; J. E. Blum; S. T. Kinsey SUMMARY Diameters of some white locomotor muscle fibers in the adult blue crab, Callinectes sapidus , exceed 500 μm whereas juvenile white fibers are <100 μm. It was hypothesized that aerobically dependent processes...

...Mary B. Rheuben ABSTRACT The ultrastructural changes associated with the early stages of degeneration of the larval mesothoracic muscle fibers of Manduca sexta were examined during the prepupal period and on the first day after ecdysis. Over this 5 day period, the muscle fibers decrease in cross...
