title: [Possibility of the transformation of muscle fibers by training and the significance of muscle biopsies for recognizing talent in sports].
abstract: Different methods for skeletal muscle fibre typing are reported. The demonstration of the ATPase, which is mostly used in the recent past, allows for the differentiation of four types, called I, IIC, IIA, and IIB. Using biochemical methods, a further division based on different myosin types is possible. The transformation of distinct fibre types by means of special training programmes may have been overestimated in the past and is assumed to be of minor importance in sports. Taking muscle biopsies for search of talents in sports does not seem to be meaningful and is unethical.
