This experiment was run to further evaluate the role of individual difference factors in perception of heart beats (cardiac awareness). The present study examined 24 male subjects who showed high and moderate levels of physical fitness. Cardiac awareness was examined using Brener-Jones type discrimination trials. Subjects discriminated first while standing quietly on a treadmill (32 trials), then while walking briskly on a motorized treadmill (32 trials), and finally during recovery from exercise (elevated HR but behavioral quiescence) (16 trials). Results showed that only the moderate fitness group showed heightened awareness during exercise, while both groups showed greater than chance awareness during recovery from exercise. Neither group was highly aware while resting before exercise. These results fail to support notions that high fitness distance runners are highly aware of cardiac function during exercise. A number of reasons for this finding are discussed.
进行该实验是为了进一步评估个体差异因素在心跳感知（心脏感知）中的作用。本研究调查了24名身体状况处于高水平和中等水平的男性受试者。使用布伦纳 - 琼斯类型的辨别试验来检测心脏感知。受试者先在跑步机上安静站立时进行辨别（32次试验），然后在电动跑步机上轻快行走时进行辨别（32次试验），最后在运动恢复期间（心率升高但行为静止）进行辨别（16次试验）。结果显示，只有中等身体状况组在运动期间表现出更高的感知，而两组在运动恢复期间的感知都高于随机水平。两组在运动前休息时都没有高度感知。这些结果未能支持高水平健身长跑者在运动期间对心脏功能有高度感知的观点。文中讨论了这一发现的一些原因。
