Acute aerobic exercise may increase cognitive processing speed among tasks demanding a substantial degree of executive function. Few studies have investigated executive function after acute exercise in older adults across various exercise intensities. Healthy females 60-75 years of age (n = 11) who were not on medications completed 20-min exercise sessions at a moderate (50%VO2max) exercise intensity and a vigorous (75%VO2max) exercise intensity. Modified flanker tasks (reaction times) and d2 tests of sustained and selective attention (components of executive function) were completed before, immediately after, and 30-min post-exercise. Results indicated that older adult females had improved scores on the modified flanker task reaction times (RTT, RTI, RTC) and d2 tests immediately after both moderate and vigorous intensity aerobic exercise. Some of these effects were maintained 30 min post-exercise. These findings suggest that an acute bout of exercise, regardless of intensity, can improve performance on tests of executive function in older women. Key pointsFew studies have investigated the effects of the intensity of exercise on executive function in older womenExecutive function improved after 20-min of aerobic exercise regardless of exercise intensity in older womenFindings from the study were not confounded by prescribed medications; all participants who were older women were not taking any medications.
急性有氧运动可能会提高在需要高度执行功能的任务中的认知处理速度。很少有研究调查不同运动强度下老年人急性运动后的执行功能。60至75岁未服用药物的健康女性（n = 11）在中等（50%最大摄氧量）运动强度和剧烈（75%最大摄氧量）运动强度下完成了20分钟的运动课程。在运动前、运动后立即以及运动后30分钟完成了改良侧翼任务（反应时间）和持续及选择性注意力的d2测试（执行功能的组成部分）。结果表明，在中等强度和剧烈强度有氧运动后，老年女性在改良侧翼任务反应时间（RTT、RTI、RTC）和d2测试中的得分立即有所提高。其中一些效果在运动后30分钟仍得以维持。这些发现表明，一次急性运动，无论强度如何，都可以改善老年女性执行功能测试的表现。要点很少有研究调查运动强度对老年女性执行功能的影响老年女性在进行20分钟有氧运动后，无论运动强度如何，执行功能都会得到改善该研究结果不受处方药的干扰；所有参与研究的老年女性均未服用任何药物。
