The effects of physical activity on sleep were evaluated in 12-month-old rats. The animals (n = 18) were induced to walk or run for 45 min in a rota-rod treadmill while control mates remained in their home cages. Immediately after the trial, they were left free to sleep for four hours, during which their electroencephalographic activity was recorded. Baseline electroencephalogram showed no differences among groups in sleep parameters and spike wave discharges during wakefulness in all rats. Sleep variables and spike wave discharges remained constant in the controls over times. On the contrary, Student's t-test for paired data indicated a decrease in spike wave discharges in both walking and running rats while paradoxical sleep rose parallel with slow wave sleep in walking animals but declined in running rats, in spite of an increment in slow wave sleep. The results seem to indicate that: i) light exercise improves sleep quality in middle aged rats, provided it is not stressful and ii) physical activity supplies important benefits to waking brain by reducing spike wave discharges.
在12月龄大鼠中评估了体育活动对睡眠的影响。将18只动物置于旋转杆式跑步机上行走或奔跑45分钟，而对照组的同伴则留在它们的笼舍中。试验结束后，让它们自由睡眠4小时，在此期间记录其脑电图活动。所有大鼠的基线脑电图显示，各组在睡眠参数和清醒时的棘波放电方面没有差异。随着时间的推移，对照组的睡眠变量和棘波放电保持不变。相反，配对数据的学生t检验表明，行走和奔跑的大鼠棘波放电均减少，而在行走的动物中，异相睡眠与慢波睡眠平行增加，但在奔跑的大鼠中异相睡眠减少，尽管慢波睡眠有所增加。结果似乎表明：i）轻度运动可改善中年大鼠的睡眠质量，前提是运动无压力；ii）体育活动通过减少棘波放电为清醒大脑带来重要益处。
