The goals of this research were to analyze cardiac sympathetic recovery patterns and evaluate whether sympathetic cardiac responses to a task challenge can be predicted using residual cardiac activity measured directly after the task (that is, during the recovery period). In two studies (total N = 181), we measured cardiac sympathetic activity, quantified as pre-ejection period and RB interval, during both task performance and the 2-min recovery period following the task. Additional analyses examined effects on the RZ interval. We found that sympathetic recovery from a task was rather quick: Cardiovascular recovery occurred within the first 30 s of the recovery period. Nevertheless, residual cardiac activity during the recovery period had predictive power for task-related cardiac activity. This suggests that sympathetic cardiac activity during recovery may serve as a useful indicator of task-related cardiac sympathetic activity. We discuss the implications of these findings for practical applications and the design of future studies.
本研究的目的是分析心脏交感神经恢复模式,并评估是否可以使用任务后直接测量的残余心脏活动(即恢复期间)来预测交感神经对任务挑战的心脏反应。在两项研究(总样本量N = 181)中,我们在任务执行期间和任务后的2分钟恢复期间测量了心脏交感神经活动,以射血前期和RB间期进行量化。额外的分析研究了对RZ间期的影响。我们发现,从任务中恢复时交感神经恢复相当迅速:心血管恢复在恢复的前30秒内发生。然而,恢复期间的残余心脏活动对与任务相关的心脏活动具有预测能力。这表明恢复期间的交感神经心脏活动可能是与任务相关的心脏交感神经活动的有用指标。我们讨论了这些发现对实际应用和未来研究设计的意义。
