REYES Q, Kenny et al. Relationship between skeletical muscular fiber type of the caprine (Capra Hircus) hindlimb and the oxidative and glicolitic capacity. Rev. Cient. (Maracaibo) [online]. 2009, vol.19, n.6, pp.589-597. ISSN 0798-2259.

With technical histochemical were studied, the muscles of the hip and the thigh of the hind limb of the goats under conditions of exploitation semi intensive with the purpose of knowing the relationship between of the different types of fibers and the oxidative and glicoltic capacity. They took samples in vivo of the muscles gluteal biceps, middle gluteal, deep glutea, vastus intermedius, vastus lateral, gastronemius, soleus, semimembranosos, semitendinosus and tensor facialatae in five (5) goats of 21-30 kg of weight. The samples froze in isopentano cooled in liquid nitrogen. The cuts were carried out in a cryostat to -20°C, with a thickness of 10 µm. The Nicotamida Adenosina Dehydrogenize diaphoreses (NADH-d) reactions were used to determine the capacity oxidative and the α-Glycerol Phosphate Dehydrogenize (α-GPD), to study the capacity glicolític. The muscle vast intermission presents 100% of fibers type I, almost all of high capacity oxidative. The muscles gluteus half and deep showed around 45% fibers type I, 22 type % IIa and 33% type IIb; approximately half of their fibers they presented high capacity oxidative and between stocking and low capacity glicolítica. The rest of the muscles had a percentage around 29% of the fibers type I, 31% of the type IIa and 40% of the type IIb; in them there was a prevalence of fibers with high and medium capacity glicolítica.
