进行了一项研究，以检验以下假设：A型（冠状动脉倾向）个体比B型（非冠状动脉倾向）个体表现出更大的主观疲劳抑制，以便坚持从事累人但具有挑战性的任务。A型和B型大学生完成了Balke跑步机测试（以步行速度），同时每隔2分钟对他们的疲劳程度进行评级。每名受试者还完成了另一项跑步机测试（以跑步速度），旨在评估最大有氧能力。受试者的有氧能力和他们在Balke测试中达到的有氧性能水平通过分析呼气来确定。每个受试者的步行表现都是按照其最大有氧能力的比例进行评分的。对所得百分比值的分析表明，A比B更努力。此外，A组的主观疲劳评分低于B组。结果进行了讨论的疲劳抑制作为一种工具的反应，以达到掌握环境。此外，亦考虑到疲劳在冠心病发病中的作用。
A study was conducted to test the hypothesis that Type A (coronary-prone) individuals would show greater suppression of subjective fatigue than Type B (non-coronary-prone) individuals in order to persist at a tiring but challenging task. Type A and Type B college students completed a Balke treadmill test (at a walking pace) while rating their fatigue at 2-minute intervals. Each subject also completed another treadmill test (at a running pace) that was designed to assess maximum aerobic capacity. Subjects' aerobic capacities and their aerobic performance levels attained on the Balke test were determined by analysis of expired air. Each subject's walking performance was scored as a proportion of his maximum aerobic capacity. Analysis of the resulting percentage values indicated greater effort among A's than B's. Moreover, the subjective fatigue ratings of A's were lower than those of B's. The results were discussed in terms of fatigue suppression as an instrumental response for attaining mastery over the environment. consideration was also given to the role of fatigue in the onset of coronary heart disease.
