摘要: | 本研究的目的是利用符号化运算和频域心律变异分析等方法来探讨禅定组和控制组的心肺功能。本研究包括15位一般受测者和7位具有禅定经验的禅修者。信号分析中包括时域和频域的方法。Miniscale symbolic dynamic(MSD)首次被使用在我的研究中来探索微观尺度随时间变化的心肺同步现象。 Pearson’s correlation coefficient为我们应用的另一方法进行量化心肺之间相互作用关系。初步结果显示,控制组在呼吸引导阶段有较好的心肺同步率,印证禅定初学者总是藉由调节呼吸来平静他们的大脑和心灵进入禅定达到良好的身心状态。此外禅定组在禅定状态和控制组在2个休息阶段的平均心肺同步率大致相同,然而,禅定组年龄皆高于控制组很多。因此,我们可以得出结论,禅定能很好地保持心肺相互作用的特性。而频域心律变异分析中显示大部分控制组受测者进入呼吸引导阶段极低频的功率百分比较低。半数以上的禅定组在禅定状态相较于控制组在2个休息阶段的极低频的功率百分也来的低。 This research was aimed to investigate the cardiorespiratory functioning of Zen-meditation group and control group by symbolic computation and frequency-domain HRV analysis. This study included 15 normal controls without Zen-meditation experience and 7 experienced Zen meditation practitioners. Signal analysis schemes include the time-domain and frequency-domain methods. Miniscale symbolic dynamic (MSD) method firstly developed in our research group was applied to explore the time-varying cardiorespiratory synchronization on the microscopic scale. Pearson’s correlation coefficient (PCC) method is another method applied to quantify cardiorespiratory interaction. Preliminary results reveal that the control group have better cardiorespiratory synchronization in the session of breathing control. In addition, Group averages of cardiorespiratory synchronization evaluated by MSD for control and Zen-meditation group are about the same. Notice that the ages of the Zen-meditation group cases are much older than the ages of the control group. Therefore, we may conclude that Zen meditation can well maintain the efficiency of cardiorespiratory interactions. In frequency domain HRV analysis, most cases of control group have lower VLF power percentage in the session of breathing control, yet, have higher VLF power percentages in the other sessions. In comparison, Most of the Zen-meditation group have VLF power percentage smaller than 45%. |
