WebbHuman skeletal muscles consist of different fibre types: slow fibres (slow twitch or type I) containing the myosin heavy chain isoform (MHC)-I and fast fibres (fast twitch or type II) containing MHC-IIa (type IIA) or MHC-IId (type IID). The following order of decreasing kinetics is known: type IID & … WebbThis staining is related to the activity of the enzyme and thus the contractility of the fibers. One fibre type lacks (Type I or slow twitch fiber) and the other one (Type II or fast twitch fiber) contains this enzyme. The soleus muscle contained predominantly slow twitch (Type I) fibers with the mean for all subjects being 80% (range 64 to 100%).
