Capillary supply of the muscle fibre population in hindlimb muscles of the cat

Abstract: Comparative analyses of the fibre content (FG, FOG, and SO fibres) and the capillary density (the number of capillaries surrounding individual fibres and the capillary/fibre ratio) were performed in hind limb muscles of the cat. Cross-sections from the tenuissimus, the biceps femoris, the lateral head (LG) and the medial head (MG) of the gastrocnemius and the soleus were cut in a cryostat. The sections were stained histochemically for the NADH2-diaphorase and alkaline (pH 9.4) actomyosin ATPase activity, which… Show more

“…Thus, soleus has a higher capillary number per mm 2 of cross sectional area, a higher capillary to fiber ratio, and a higher number of capillaries around a single fiber, compared to lateral gastrocnemius and the superficial portion of the medial gastrocnemius. As Table 1 reveals, however, vascular differences between Myrhage (1978) and Myrhage and Eriksson (1980). SO: slow oxidative; FOG: fast oxidative-glycolytic; FG: fast glycolytic.…”

“…Barker, 1962), a denser capillarity compared to glycolytic areas (e.g. Romanul, 1964;Mai et al, 1970;Plyley and Groom, 1975;Myrhage, 1978;Myrhage and Eriksson, 1980;Gray et al, 1983;Stephens, 1985;Ovalle et al, 1999;Suzuki et al, 2000), a richer oxygen consumption (Adair et al, 1990), a higher density of mitochondria (Hoppeler and Kayar, 1988), a higher number of action potentials reaching them per day (Brown et al, 1976;Hennig and L . omo, 1985;Gordon and Patullo, 1993), a lack of NO synthase-1 (present only in glycolytic fibers, Lincoln and Harb, 1998), etc.…”

“…Indeed, satellite cell proliferation which is required during muscle repair and may be important in muscle recovery after disuse (Alway, et al 2017b; Alway, et al 2011; Alway, et al 2014c; Alway, et al 2013; Brooks, et al 2018), is greater in fibers with a high capillarity to fiber ratio (Joanisse, et al 2018; Nederveen, et al 2018). Thus, it is possible that refraction of capillarity and therefore blood flow during unloading (Desplanches, et al 1990; Hirayama, et al 2017) is reversed during reloading, especially in the soleus fibers, which have greater capillarity than the gastrocnemius muscle fibers (Myrhage 1978). The dissimilar responses in type I fibers in the gastrocnemius and soleus muscles might be the result of non-uniform changes in vascularity throughout skeletal muscle arteriolar networks between soleus and gastrocnemius fibers (Laughlin and Roseguini 2008) leading to different potentials for the type I fibers in gastrocnemius and soleus muscles to receive humoral anabolic compounds (e.g., myokines) during reloading.…”

“…The capillary supply of skeletal muscle is an important factor for aerobic work power (24). It is correlated to the amount of red (oxidative) muscle fibers since these fibers are generally supplied by more capillaries than white fibers (15,22,32,34,37,44). Moreover, red muscles are described as containing a peculiar capillary pattern that is characterized by mostly tortuous capillaries (42,43,46).…”
