In rabbits blood flow was measured in 19 muscles with the radioactive microsphere technique. Fibre type composition (SO, slow-twitch oxidative; FOG, fast-twitch oxidative-glycolytic; FG, fast-twitch glycolytic) was determined histochemically for the same muscles. While no significant changes occur in the transition from quiet wakefulness (QW) to synchronized sleep (SS), in desynchronized sleep (DS) blood flow decreases in SO and increases in FOG and FG fibres. These changes may be related to the changes in motor activity characteristic of DS: muscle atonia and twitches, respectively.
在兔子身上，采用放射性微球技术测量了19块肌肉的血流量。通过组织化学方法确定了相同肌肉的纤维类型组成（SO，慢肌氧化型；FOG，快肌氧化糖酵解型；FG，快肌糖酵解型）。从安静觉醒（QW）过渡到同步睡眠（SS）时未发生显著变化，但在去同步睡眠（DS）时，SO纤维的血流量减少，而FOG和FG纤维的血流量增加。这些变化可能与DS特有的运动活动变化有关：分别为肌肉张力缺失和抽搐。
