Cortical changes resulting from physical activity and differences in the estimation of the time of practitioners and non-practitioners of physical activity have already been documented. However, there aren't studies that compare the cortical responses of the time estimate between these groups. Therefore, this study aimed to investigate the influence of the level of physical activity in time estimation and beta band activity in frontal regions, specifically in the dorsolateral prefrontal cortex, ventrolateral prefrontal cortex, and parietal cortex during the task of estimating time in practitioners and non-practitioners of physical activity. After characterizing the sample, the signal was captured using an electroencephalogram during a task to estimate the time of four intervals of supraseconds. The results indicated that the practitioners of physical activity had lower errors in the evaluation of time for the intervals of 1 s, 7 s, and 9 s. The beta band showed less activity among practitioners of physical activity. The correlation between task performance and the absolute power of the beta band proved to be positive in the task of estimating time in the 7 s, and 9 s intervals. It was concluded that participants involved in the regular practice of physical activity showed underestimation in the temporal judgment and lower absolute power of the beta band during the time estimate.

由体育活动引起的皮层变化以及从业者和非从业者的体育活动时间估计的差异已经被记录在案。然而，没有研究比较这些组之间时间估计的皮层反应。因此，本研究旨在调查体力活动水平对时间估计和额叶区域 β 带活动的影响，特别是在从业人员和非专业人员进行时间估计任务期间，背外侧前额叶皮层、腹外侧前额叶皮层和顶叶皮层的影响。 - 体力活动的从业者。在对样本进行表征后，在任务期间使用脑电图捕获信号以估计四个超秒间隔的时间。结果表明，体力活动从业者在1 s、7 s和9 s时间间隔内的时间评估误差较低。β 波段显示身体活动从业者的活动较少。在 7 s 和 9 s 间隔内估计时间的任务中，任务绩效与 beta 波段的绝对功率之间的相关性被证明是正的。得出的结论是，参与定期体育活动的参与者在时间估计期间表现出对时间判断的低估和较低的 β 波段绝对功率。在 7 s 和 9 s 间隔内估计时间的任务中，任务绩效与 beta 波段的绝对功率之间的相关性被证明是正的。得出的结论是，参与定期体育活动的参与者在时间估计期间表现出对时间判断的低估和较低的 β 波段绝对功率。在 7 s 和 9 s 间隔内估计时间的任务中，任务绩效与 beta 波段的绝对功率之间的相关性被证明是正的。得出的结论是，参与定期体育活动的参与者在时间估计期间表现出对时间判断的低估和较低的 β 波段绝对功率。
