通过肌电图记录研究了新生大鼠的游泳行为。研究表明，早期游泳模式具有时间参数高度不稳定的特点。发现随着年龄的增长，每条腿的瞬时周期变异性和反相位模式的变异性都有所下降。此外，在发育过程中，前腿和后腿的活动发生了分离。虽然涉及前腿的模式总是非常不稳定，但随着时间的推移，后肢活动出现了相当大的改善。
Swimming behaviour was studied in neonate rats by carrying out electromyographic recordings. The study showed that the early swimming pattern was characterized by highly instable temporal parameters. A decrease was found to occur with age in the variability of the instantaneous period in each leg and in that of the antiphase pattern. Moreover, a dissociation occurred during development between the foreleg and the backleg activity. While patters involving the forelegs always remained extremely instable, a considerable improvement was found to occur with time in the hindlimb activity.
