An experiment was conducted to determine whether a brief program of aerobic exercise would reduce the heart rate and subjective responses of high- and low-fit subjects to a psychologic stressor. Thirty-four high-fit and 34 low-fit subjects were exposed to a moderate stressor (recall of digits backwards test) while their heart rates and subjective responses were monitored. Approximately half of the high- and low-fit subjects then participated in a 13-week aerobic exercise training program, whereas the other subjects did not. After the 13-week period, the subjects were again exposed to the stressor. Results indicated that a) in the pretest the low-fit subjects showed a greater heart rate response to the stressor than the high-fit subjects, b) the training program was effective for increasing subjects' levels of aerobic fitness, and c) the training program was effective for reducing the heart rate response to the stressor of low-fit subjects. These findings provide support for the relationship between fitness and the response to psychologic stressors and they suggest that aerobic training may be an effective way of helping low-fit persons deal with psychologic stressors.
进行了一项实验，以确定一个简短的有氧运动计划是否会降低健康状况高和低的受试者对心理压力源的心率和主观反应。34名健康状况高的受试者和34名健康状况低的受试者在接受中度压力源（倒背数字测试）时，其心率和主观反应受到监测。然后，大约一半的健康状况高和低的受试者参加了一个为期13周的有氧运动训练计划，而其他受试者没有参加。在13周的时间段结束后，受试者再次接受压力源测试。结果表明：a）在预测试中，健康状况低的受试者对压力源的心率反应比健康状况高的受试者更大；b）训练计划对提高受试者的有氧适能水平有效；c）训练计划对降低健康状况低的受试者对压力源的心率反应有效。这些发现为适能与对心理压力源的反应之间的关系提供了支持，并表明有氧训练可能是帮助健康状况低的人应对心理压力源的有效方法。
