Fibre types in the 7 forelimb muscles of Rana temporaria were characterized according to actomyosin ATP-ase activity and 5 distinct fibre types were distinguished. Besides the twitch fibres of type I, IIA, IIB, and IIC, also the tonic fibres were found in the examined muscles. The metabolic profiles of these fibre types was identified on the basis of SDH activity. The scores of SDH activity of different fibre types overlapped and correlation between fibre types defined by ATP-ase activity and their metabolic profiles was not found. All investigated muscles showed the heterogenous distribution of fibre types. Caput superius m. extensoris carpi radialis and caput mediale m. anconei were composed of 4 and 3 fibre types, respectively, in the opposite to the other ones which contained all 5 types of fibres.
根据肌动球蛋白ATP酶活性对泽蛙7块前肢肌肉中的纤维类型进行了表征，并区分出5种不同的纤维类型。除了I型、IIA型、IIB型和IIC型的快肌纤维外，在所检查的肌肉中还发现了慢肌纤维。这些纤维类型的代谢特征是根据琥珀酸脱氢酶（SDH）活性确定的。不同纤维类型的SDH活性得分重叠，未发现由ATP酶活性定义的纤维类型与其代谢特征之间的相关性。所有被研究的肌肉都显示出纤维类型的不均匀分布。桡侧腕伸肌上半肌和肘肌内侧头分别由4种和3种纤维类型组成，而其他肌肉则包含所有5种纤维类型。
