Cardiorespiratory fitness and acute aerobic exercise effects on cognitive function were assessed for 28 higher- and lower-fit adults during a flanker task by comparing behavioral and neuroelectric indices of action monitoring. The error-related negativity, error positivity, and N2 components, as well as behavioral measures of response speed, accuracy, and post-error slowing were measured following a 30-minute acute bout of treadmill exercise or following 30-minutes of rest. A graded maximal exercise test was used to measure cardiorespiratory fitness by assessing maximal oxygen uptake. Results indicated that higher-fit adults exhibited reduced error-related negativity amplitude, increased error positivity amplitude, and increased post-error response slowing compared with lower-fit adults. However, acute exercise was not related to any of the dependent measures. These findings suggest that cardiorespiratory fitness, but not acute aerobic exercise, may be beneficial to behavioral and neuroelectric indices of action monitoring following errors of commission by increasing top-down attentional control.
通过比较动作监测的行为和神经电指标，对28名高体能和低体能成年人在侧翼任务期间的心肺适能以及急性有氧运动对认知功能的影响进行了评估。在30分钟的急性跑步机运动或30分钟的休息后，测量了与错误相关的负波、错误正波和N2成分，以及反应速度、准确性和错误后反应减慢的行为指标。采用分级最大运动试验，通过评估最大摄氧量来测量心肺适能。结果表明，与低体能成年人相比，高体能成年人的错误相关负波幅度降低、错误正波幅度增加、错误后反应减慢增加。然而，急性运动与任何一项相关指标均无关。这些发现表明，心肺适能而非急性有氧运动，可能通过增强自上而下的注意力控制，对执行错误后的动作监测行为和神经电指标有益。
