“…The decrease in the LF power and the LF/HF ratio after the practice of CM suggests a shift toward vagal dominance. This is similar to HRV changes (Lu & Kuo, 2003). The immediate effect of practicing Wai Tan Kung was to enhance vagal modulation and to suppress sympathetic modulation.…”

Heart rate variability (HRV) was studied in cyclic meditation (CM) and supine rest (SR). CM included yoga postures followed by guided relaxation. Forty-two male volunteers were assessed in CM and SR sessions of 35 minutes, where CM or SR practice was preceded and followed by 5 minutes of SR. During the yoga postures of CM and after CM, low frequency power and the low frequency to high frequency power ratio decreased, whereas high frequency power increased. Heart rate increased during the yoga postures and decreased in guided relaxation and after CM. There was no change in SR. Hence, it appeared that predominantly sympathetic activation occurred in the yoga posture phases of CM while parasympathetic dominance increased after CM.

“…It is already known that both WTK and TCC improve the health of the subjects (Lu and Kuo, 2003a;2003b). While independent studies of TCC and WTK have compared practicing vs. non-practicing controls, no previous study has been done to compare these two similar but distinct forms of Oriental calisthenics.…”

The health of the middle-aged and elderly people is a major concern given the rapid aging population and rising costs of medical care. Low-impact exercise on a regular basis is ideal for maintaining the well-being of an aging population. Tai Chi Chuan (TCC) is the most well-known and most widely practiced form of low-impact martial arts therapy and has been shown to have positive health effects. A lesser-known form of martial arts therapy is Wai Tan Kung (WTK), which our previous study found to have positive health effects as well. The present study compares the effects of TCC and WTK on autonomic nervous system modulation and on hemodynamics in adults among non-exercising control (30), TCC practitioners (30) and WTK practitioners (30). Our study found that in a short-term, WTK and TCC exercises enhanced the vagal modulation, lowered the sympathetic modulation and lowered arterial blood pressures in the practitioners. It was also observed that the forced vital capacity of TCC practitioners was significantly higher than that of WTK practitioners before exercise. There were no significant differences in the percentage changes in HRV measures and hemodynamics between WTK and TCC practitioners 30 and 60 min after exercise, indicating that the effects of WTK and TCC were similar in magnitude. In conclusion, TCC and WTK are comparable to each other in terms of their effects on autonomic nervous system modulation and hemodynamics, thus suggesting that WTK can be just as beneficial as TCC as a form of low-impact exercise for elderly adults.

“…HRV offers a reliable measure of cardiovascular autonomic responses, and the frequency domains of HRV consist of high-frequency (HF), low-frequency (LF), and very-low-frequency (VLF) components ( 15 ). HF represents exclusively parasympathetic activity ( 16 ), and VLF reflects neuroendocrine and thermoregulatory influences on the heart ( 17 ), renin–angiotensin–aldosterone modulation ( 18 ), and vagal withdrawal ( 19 ). LF is proposed to reflect a complex mix of sympathetic, parasympathetic, and other unidentified factors ( 20 ).…”

Childhood trauma is known to be related to emotional problems, quantitative electroencephalography (EEG) indices, and heart rate variability (HRV) indices in adulthood, whereas directions among these factors have not been reported yet. This study aimed to evaluate pathway models in young and healthy adults: (1) one with physiological factors first and emotional problems later in adulthood as results of childhood trauma and (2) one with emotional problems first and physiological factors later. A total of 103 non-clinical volunteers were included. Self-reported psychological scales, including the Childhood Trauma Questionnaire (CTQ), State–Trait Anxiety Inventory, Beck Depression Inventory, and Affective Lability Scale were administered. For physiological evaluation, EEG record was performed during resting eyes closed condition in addition to the resting-state HRV, and the quantitative power analyses of eight EEG bands and three HRV components were calculated in the frequency domain. After a normality test, Pearson’s correlation analysis to make path models and path analyses to examine them were conducted. The CTQ score was significantly correlated with depression, state and trait anxiety, affective lability, and HRV low-frequency (LF) power. LF power was associated with beta2 (18–22 Hz) power that was related to affective lability. Affective lability was associated with state anxiety, trait anxiety, and depression. Based on the correlation and the hypothesis, two models were composed: a model with pathways from CTQ score to affective lability, and a model with pathways from CTQ score to LF power. The second model showed significantly better fit than the first model (AICmodel1 = 63.403 > AICmodel2 = 46.003), which revealed that child trauma could affect emotion, and then physiology. The specific directions of relationships among emotions, the EEG, and HRV in adulthood after childhood trauma was discussed.
