研究了成年Sprague-Dawley大鼠自由跑轮模式。连续5天记录每20秒车轮转数。雌性比雄性跑得多，但都主要在晚上跑，在开始时达到高峰，在白天下降到低水平。原木幸存者图显示，跑步发生在被长时间不跑步隔开的不同时期。夜间跑步次数的减少和性别差异都是由于跑步持续时间和跑步速度的变化。从非跑步时间的长短可以看出，开始跑步的时间在两性中是相似的，并且在整晚都保持不变。从独立的起始和终止因素及其与饮食模式的相似之处讨论了跑步。
The pattern of ad lib wheel running was studied in adult Sprague-Dawley rats. Wheel turns per 20 seconds were recorded for 5 days. Females ran more than males but both ran chiefly at night, with a peak at the beginning and a decline to low levels by daytime. Log-survivor plots showed running occurred in distinct episodes separated by long periods of nonrunning. Both the nightly decrease and the sex difference in running were due to changes in duration of episodes and the running speed. Initiation of running, as reflected in the length of nonrunning periods was similar in both sexes and remained constant over the night. Running was discussed in terms of independent initiation and termination factors and its parallels to eating patterns.
