Spatial and Temporal Variability of Blood Flow in Stimulated Dog Gastrocnemius Muscle
Estimations of muscle blood flow distribution by radioactive microsphere trapping have shown a widely uneven distribution in the isolated-perfused gastrocnemius of the dog (Piiper et al., 1985) and in leg muscles (vastus lateralis, gastrocnemius and triceps brachii) of intact dogs (Pendergast et al., 1985). Moreover, the blood flow heterogeneity, already large at rest, was found to increase both during artificial stimulation and natural exercise.
