A number of respiratory and circulatory parameters was measured in the Larger Spotted Dogfish Scyliorhinus stellaris before, during and after periods of spontaneous swimming. During swimming the gill ventilation was increased, mainly due to increased ventilatory stroke volume, the respiratory frequency showing a small rise only, and the cardiac output was increased at only slightly elevated cardiac frequency. Coordination between cardiac, ventilatory or locomotor (tail-beat) rhythms was not observed. The decrease in utilization of inspired water O2 during swimming was attributable to diffusion limitation in branchial O2 transfer. A considerable fraction of the total net amount of O2 required for swimming was taken up during the recovery phase. From the observations that (1) the decrease in gill ventilatory flow after cessation of swimming revealed a very rapid component (followed by a slow component), and that (2) changes in swimming speed were reflected by immediate changes in momentary ventilatory flow, it is concluded that the increased ventilation during swimming was in part mechanical-passive and/or due to nervous coupling between respiratory and locomotor centers.
在大斑星鲨（Scyliorhinus stellaris）自发游泳前、游泳期间和游泳后，测量了一些呼吸和循环参数。游泳期间，鳃通气增加，主要是由于通气冲程容积增加，呼吸频率仅略有上升，心输出量增加时心率仅略有升高。未观察到心脏、通气或运动（尾拍）节律之间的协调。游泳期间吸入水中氧气利用率的降低归因于鳃部氧气转移中的扩散限制。游泳所需总净氧量的相当一部分在恢复阶段被吸收。从以下观察结果可以得出结论：（1）游泳停止后鳃通气流量的下降显示出一个非常快速的成分（随后是一个缓慢的成分），以及（2）游泳速度的变化通过瞬时通气流量的立即变化反映出来，游泳期间通气增加部分是机械被动的和/或由于呼吸和运动中枢之间的神经耦合。
