Abstract

To obtain evidence on the relative importance of exercise and emotion in the cardiovascular changes of fighting in the cat, the changes during fighting were compared with changes during a mild non-emotional exercise (walking on a treadmill at low speed), and during confrontation without fighting (preparation for fighting), an emotional condition accompanied by no or very little motor activity.2. The direction of change of all variables we measured, iliac and mesenteric flows and conductances, total peripheral conductance, heart rate, cardiac output and blood pressure, was similar in both fighting and exercise.3. Some of the cardiovascular manifestations of preparation for fighting were very different from those of motor activity. These were iliac vasoconstriction, a fall in cardiac output, and often a strong bradycardia, all of these changes being in the opposite direction to changes during exercise and fighting.4. It is suggested that the changes during preparation for fighting represent the cardiovascular manifestations of an emotional state, and that during fighting these manifestations are superseded and masked by changes due to motor activity.

摘要

为了获取关于运动和情绪在猫打架时心血管变化中相对重要性的证据，将打架期间的变化与轻度非情绪性运动（低速在跑步机上行走）期间的变化以及无打斗的对峙（准备打架）期间的变化进行了比较，对峙是一种伴有极少或没有运动活动的情绪状态。
我们所测量的所有变量（髂动脉和肠系膜血流量及传导率、总外周传导率、心率、心输出量和血压）在打架和运动时的变化方向相似。
准备打架时的一些心血管表现与运动活动时的表现非常不同。这些表现包括髂动脉血管收缩、心输出量下降以及常常出现强烈的心动过缓，所有这些变化都与运动和打架时的变化方向相反。
有人提出，准备打架时的变化代表了一种情绪状态的心血管表现，而在打架期间，这些表现被运动活动引起的变化所取代和掩盖。
