练放松功过程中入静指标的选择

本工作观察了30例练放松功者在练功时的脑电、肌电、呼吸、皮肤电、指端血管容积、心率和皮温等生理指标的变化。实验结果表明,在练功时上述各项指标都有一定程度的变化。其中脑电α波增加,肌电发放减少,呼吸周期和幅度变异系数变小、呼吸频率和心率减慢在每个练功者身上均可发生,故认为这些是鉴别入静程度所必需的指标。

Selection of the Indices of Meditation in Practice of "Relaxing Exercise"

Thirty patients practiced"Relaxing Exercise",their EEG,EMG,EKG,finger plethysmography,skin potential,skin temperature and respiratory movements were simultaneously recorded by using a polygraph. The findings showed that their physiological responses had marked changes after practicing"Relaxing Exercise"for three months.Of these responses,EEG spectral analysis showed that the alpha wave increased from 30.1% to 37.2%;it was found that the total energy of electromyography from 0 to 500 Hz had an obvious reduction in EMG spectral analysis;the variation coefficient of the respiration circle and amplitude reduced from 14% to 12%;respiration frequency slowed down from 15.3 to 13.8 times each minute;and heart rate increased from 836 ms to 881 ms per beat.The conclusion is that all the above physiological responses are valuable in estimating the state of meditation in the practice of"Relaxing Exercise".
