The objective was to study male and female rats exposed to Activity-Based Anorexia (ABA; simultaneous exposition to food restriction and free access to an activity wheel) under two conditions of sound attenuation, by means of different arrangements of wheels (standard versus isolation) in the laboratory room. Regardless of the sound attenuation condition, all but one male and one female with access to wheels had to be removed from the experiment, but extended ABA endurance was found in rats in the sound attenuation condition. Furthermore, significantly lower levels of running were observed in both males and females under the sound attenuation arrangement in the isolation condition. The results suggest that external stimulation plays a role in the activity displayed by rats exposed to ABA, and that the reduction of external stimulation diminishes running but does not protect rats from developing ABA.
目的是研究雄性和雌性大鼠在两种隔音条件下（通过实验室房间中轮子的不同布置，即标准布置和隔离布置）暴露于基于活动的厌食症（ABA；同时接受食物限制和自由使用活动轮）的情况。无论隔音条件如何，所有雄性和雌性大鼠中，只要有一只接触到轮子，就必须从实验中移除，但在隔音条件下，ABA 耐力延长的大鼠被发现。此外，在隔离条件下的隔音布置中，无论是雄性还是雌性大鼠，跑步的水平都明显降低。结果表明，外部刺激在暴露于 ABA 的大鼠所表现出的活动中发挥作用，外部刺激的减少会减少跑步，但不能保护大鼠免受 ABA 的影响。
