The present study was designed to investigate the effects of different types of physical fatigue-past demand for exertion-on the performance of a visual detection task performed with and without masking. 31 male subjects were first administered a VO2 max test and familiarized with the detection task. They were divided into two groups to control potential effects of masking. They were subjected to three experimental treatment involving the utilization of different sources of energy: (a) a short anaerobic alactic acid effort recruiting phosphocreatine, (b) a supramaximal effort (anaerobic lactic acid) recruiting glycogen without oxygen, and (c) a progressive (partially anaerobic) effort recruiting glycogen and oxygen. All three were performed on a treadmill. Blood samples were collected for the anaerobic lactacid and the partially anaerobic exercises. Once fatigued, all subjects undertook the detection task. A 2 X 3 X 2 X 8 analysis of variance, with repeated measures on the last three factors, was applied to the data (mask/no mask X type of exercise X pre-post performance measures X location of the letter to be detected). No significant difference was found for either the main effects or interactions, except for the location of the letter and the mask/no mask condition. It appears therefore that a physically fit population (mean VO2 max = 62.39 ml X kg(-1) X min(-1)) shows no detectable decrement in a perceptual task performed after fatiguing exercises recruiting various types of energy sources.
本研究旨在调查不同类型的身体疲劳（过去的用力需求）对在有掩蔽和无掩蔽条件下执行视觉检测任务的表现的影响。31名男性受试者首先进行了最大摄氧量测试，并熟悉了检测任务。他们被分为两组以控制掩蔽的潜在影响。他们接受了三种涉及利用不同能量来源的实验处理：(a) 一次短暂的无氧非乳酸用力，动用磷酸肌酸；(b) 一次超最大用力（无氧乳酸），无氧动用糖原；(c) 一次渐进性（部分无氧）用力，动用糖原和氧气。所有这三种处理均在跑步机上进行。采集了无氧乳酸运动和部分无氧运动后的血样。一旦疲劳，所有受试者都进行检测任务。对数据应用了2×3×2×8方差分析，对最后三个因素进行重复测量（掩蔽/无掩蔽×运动类型×运动前后的表现测量×待检测字母的位置）。除了字母的位置和掩蔽/无掩蔽条件外，主效应或交互作用均未发现显著差异。因此，看起来身体状况良好的人群（平均最大摄氧量 = 62.39毫升×千克⁻¹×分钟⁻¹）在进行了动用各种能量来源的疲劳运动后执行的感知任务中，未显示出可检测到的能力下降。
