Effect of rhythmic tetanic skeletal muscle contractions on peak muscle perfusion.
The purpose of this investigation was to examine the effect of rhythmic tetanic skeletal muscle contractions on peak muscle perfusion by using spontaneously perfused canine gastrocnemii in situ. Simultaneous pulsatile blood pressures were measured by means of transducers placed in the popliteal artery and vein, and pulsatile flow was measured with a flow-through-type transit-time ultrasound pro...

متن کاملCan inorganic phosphate explain sag during unfused tetanic contractions of skeletal muscle?
We test the hypothesis that cytosolic inorganic phosphate (Pi) can account for the contraction-induced reductions in twitch duration which impair summation and cause force to decline (sag) during unfused tetanic contractions of fast-twitch muscle. A five-state model of crossbridge cycling was used to simulate twitch and unfused tetanic contractions. As Pi concentration ([Pi]) was increased from...
متن کاملEnergy liberation and chemical change in frog skeletal muscle during single isometric tetanic contractions
Recent data obtained from Rana temporaria sartorius muscles during an isometric tetanus indicate that the time-course of phosphocreatine (PC) splitting cannot account for the total energy (heat + work) liberation (Gilbert et al. 1971. J. Physiol. (Lond.) 218:)63). As this conclusion is important to an understanding of the chemical energetics of contraction, similar experments were performed on ...
متن کاملHeterogeneity of skeletal muscle perfusion and metabolism.
In this issue of the Journal of Applied Physiology, Mizuno and colleagues (5) report the use of positron emission tomography (PET) in human skeletal muscle (knee extensors) both at rest and at 30 min after exhaustive single-leg cycling. They were able to measure regional perfusion and O2 consumption in five areas situated at an equal distance over a proximal-todistal axis of 12 cm. Their princi...
