To investigate the effect of physical exertion on simple reaction time and continuous attention of sport participants, an experiment was conducted with 46 male university students and 12 male cyclists. The subjects were assigned to three experimental and two control groups. The subjects of the experimental groups were asked to perform, following a 5-min, period of warming up, a high intensity exercise protocol for 5 min., on a mechanically braked cycle ergometer (Group A) or a moderate intensity exercise protocol for 30 min, on the same cycle ergometer (Groups B and C). Shortly before and immediately after the physical exercise subjects of all groups were asked to perform a test of simple reaction time and continuous attention. The subjects of the control groups were asked to perform at rest both tests of the simple reaction time and the continuous attention twice, with a 10-min. and a 35-min. interval between the first and second attempts, respectively. The results did not support the notion that exercise of moderate or high intensity influences significantly the cognitive performance of aerobically trained or untrained subjects. The results are discussed in the light of the current research findings concerning exertion and human psychomotor performance.
为研究体力消耗对运动参与者简单反应时和持续注意力的影响，对46名男大学生和12名男自行车运动员进行了一项实验。将受试者分为三个实验组和两个对照组。要求实验组的受试者在进行5分钟的热身运动后，在机械制动的自行车测力计上进行5分钟的高强度运动方案（A组），或在同一自行车测力计上进行30分钟的中等强度运动方案（B组和C组）。在体育锻炼前不久和刚结束后，要求所有组的受试者进行简单反应时和持续注意力测试。要求对照组的受试者在休息状态下进行两次简单反应时和持续注意力测试，第一次和第二次测试之间的间隔分别为10分钟和35分钟。结果并不支持中等强度或高强度运动对有氧训练或未训练受试者的认知表现有显著影响这一观点。根据当前关于体力消耗和人类心理运动表现的研究结果对结果进行了讨论。
