本研究采用停止-任务范式，探讨中度稳态运动对反应执行和反应抑制的时间过程效应。10名参与者在运动后立即和运动停止后30分钟，在严格控制的负荷强度（最大有氧能的40%）下进行停止信号任务。结果表明，适度运动增强了受试者在时间压力下执行反应的能力（更短的Go反应时间，准确性不变的RT），但也增强了受试者保留正在进行的运动反应的能力（更短的停止信号RT）。目前的结果表明，运动的有益效果不仅限于运动反应任务，也不限于运动过程中的认知任务。在运动停止后52分钟内，运动对反应执行和反应抑制的有益影响仍然存在。(C) 2009爱思唯尔公司版权所有。
This research aimed to investigate the time course effect of a moderate steady-state exercise session on response execution and response inhibition using a stop-task paradigm. Ten participants performed a stop-signal task whilst cycling at a carefully controlled workload intensity (40% of maximal aerobic power), immediately following exercise and 30 min after exercise cessation. Results showed that moderate exercise enhances a subjects' ability to execute responses under time pressure (shorter Go reaction time, RT without a change in accuracy) but also enhances a subjects' ability to withhold ongoing motor responses (shorter stop-signal RT). The present outcomes reveal that the beneficial effect of exercise is neither limited to motor response tasks, nor to cognitive tasks performed during exercise. Beneficial effects of exercise remain present on both response execution and response inhibition performance for up to 52 min after exercise cessation. (C) 2009 Elsevier Inc. All rights reserved.
