The aim of this study was to analyse the effects of different types of metabolic fatigue, induced by anaerobic alactacid, anaerobic lactacid, sub-maximal aerobic, and maximal aerobic efforts, on the performance of a sensory task (peripheral threshold detection), a sensory-motor task (coincidence-anticipation), and a cognitive task (recall in central vision). Each of three experimental groups performed one of the above-mentioned tasks under all types of fatigue. Running bouts on a treadmill were used to induce the different types of fatigue. Results show that performance in peripheral vision improves with all types of effort. For coincidence-anticipation, only constant error is affected by anaerobic alactacid and maximal aerobic efforts; the former producing a change in behavior from lateness to anticipation, whereas the latter significantly reduces lateness. Finally, performance in the cognitive task is significantly disturbed by the maximal aerobic exercise. It is suggested that, while sensory and adaptive behaviors improve with previous physical work, cognitive behavior is handicapped by highly demanding activities, that is, activities requiring aerobic maximal efforts.
本研究的目的是分析由无氧非乳酸、无氧乳酸、次最大有氧和最大有氧运动所诱发的不同类型代谢性疲劳，对一项感觉任务（外周阈值检测）、一项感觉运动任务（同步-预判）和一项认知任务（中央视觉回忆）表现的影响。三个实验组中的每一组在所有类型的疲劳状态下执行上述任务之一。在跑步机上跑步用于诱发不同类型的疲劳。结果表明，在所有类型的运动中，外周视觉的表现都会提高。对于同步-预判任务，只有恒定误差受无氧非乳酸和最大有氧运动的影响；前者使行为从延迟转变为预判，而后者显著减少延迟。最后，认知任务的表现受到最大有氧运动的显著干扰。研究表明，虽然感觉和适应性行为会随着先前的体力活动而改善，但认知行为会受到高要求活动的阻碍，即需要最大有氧运动的活动。
