Conference paper


Striated muscles differ in respect to velocity, power of contraction and resistence to fatigue. The striated muscle is a very plastic and adaptable tissue [8]; transformation of fibre types, muscle hypertrophy or atrophy can appear within a short time [3, 4, 6]. Alterations occur as a result of functional or anatomical demands, hormonal influence etc. Both denervation and immobilization bring about muscle atrophy and diminishing of the contractile apparatus (references in [3, 4, 7, 9]), but differences between the effect of inactivity and that of lack of innervation are not fully understood. The type-dependent differences in muscle reaction are also unclear. All these issues are of practical importance.
