本研究旨在探讨急性有氧运动对人体抑制系统的影响。在研究人体躯体运动抑制加工的神经机制时，go/no-go任务是记录事件相关电位的一个有用范式。10名受试者在控制条件和运动条件下进行体感去/不去任务。在控制条件下，受试者在休息20分钟之前和之后执行go/no-go任务。在运动条件下，受试者在跑步机跑步15 min之前和之后进行go/no-go任务，每个受试者的运动强度分别设定为峰值摄氧量的50%。我们在所有条件下都成功记录到了清晰的N140成分，并发现在中度运动期间，Fz和Cz处的no-go-N140的峰值幅度显著增强。相反，在对照条件下，Fz和Cz没有显著变化。这些结果表明，适度运动可以影响no-go-N140的振幅，这可以解释为人类中枢神经系统抑制过程的一个指标。人类的抑制系统是一个重要的认知过程，该系统可能是假设的体育锻炼在整个生命周期中维持和改善认知表现的能力的基础。(C)2015爱思唯尔爱尔兰有限公司版权所有。
This study evaluated the influence of acute aerobic exercise on the human inhibitory system. For studies on the neural mechanisms of somato-motor inhibitory processing in humans, the go/no-go task is a useful paradigm for recording event-related potentials. Ten subjects performed somatosensory go/no-go tasks in a control condition and exercise condition. In the control condition, the subjects performed the go/no-go task before and after 20 min of rest. In the exercise condition, the subjects performed the go/no-go task before and after 15 min of treadmill running with the exercise intensity set individually for each subject at 50% of peak oxygen intake. We successfully recorded a clear-cut N140 component under all conditions, and found that the peak amplitude of no-go-N140 at Fz and Cz was significantly enhanced during moderate exercise. In contrast, there were no significant changes in Fz and Cz in the control condition. These results suggest that moderate exercise can affect the amplitude of no-go-N140, which could be interpreted as an index of the human inhibition process in the central nervous system. The human inhibitory system is an important cognitive process, and this system may underlie the hypothetical ability of physical exercise to maintain and improve cognitive performance throughout the lifespan.
