Glycogen synthetase (I + D) and phosphorylase (à + b) activity was determined in human skeletal muscle biopsies with different muscle fibre composition and in dissected an pooled batches of the two main muscle fibre types: slow twitch (ST) and fast twitch (FT), respectively. Glycogen synthetase (I + D) activity remained unchanged as the per cent of FT fibres increased, but phosphoyrlase (à + b) activity was found to increase. A similar activity pattern was found in dissected and FT fibres as compared to ST fibres, i.e. the same glycogen synthetase activity but heightened phosphoyrlase activity.
在具有不同肌纤维组成的人体骨骼肌活检样本中，以及分别在解剖并汇集的两种主要肌纤维类型：慢肌纤维（ST）和快肌纤维（FT）中，测定了糖原合成酶（I + D）和磷酸化酶（a + b）的活性。随着FT纤维百分比的增加，糖原合成酶（I + D）活性保持不变，但发现磷酸化酶（a + b）活性增加。与ST纤维相比，在解剖的FT纤维中发现了类似的活性模式，即糖原合成酶活性相同，但磷酸化酶活性升高。
