Effects of qigong on cardiorespiratory changes: a preliminary study

Effects of Different Inspiratory Muscle Training Protocols on Exercise Capacity, Respiratory Muscle Strength, and Health-Related Quality of Life in Patients with Hypertension

Aim

This study aimed to explore how varying inspiratory muscle training workloads affect exercise capacity, health-related quality of life (HrQoL), depression, peripheral and respiratory muscle strength, pulmonary function, dyspnea, fatigue, and physical activity levels in hypertension (HT) patients.

Methods

A randomized, controlled three-arm study. Forty-five patients (58.37 ± 8.53 y, 7F/38M) with HT received IMT (7 days/8 weeks) by POWERbreathe® Classic LR device and were randomized to control group (CG, 10% maximal inspiratory pressure (MIP), n: 15), low-load group (LLG, 30% MIP), and high-load group (HLG, %50 MIP). Exercise capacity, HrQoL, depression, peripheral and respiratory muscle strength, pulmonary function, fatigue, physical activity level, dyspnea, and sleep quality were evaluated before and after the training.

Results

Exercise capacity, physical functioning, peripheral muscle strength, and resting dyspnea were statistically significantly improved in HLG and LLG after the training compared to CG (p < 0.05). Similar improvements in perception of depression, fatigue, and sleep quality were seen within and between the groups (p > 0.05). Statistically significant differences were found within all the groups in terms of MIP and PEF values of respiratory functions (p < 0.05). The superior improvement in the physical activity level was found in the HLG (p < 0.05). Discussion. High-load IMT was particularly effective in increasing physical activity level, peripheral muscle strength, exercise capacity, and improved HrQoL. Low-load IMT was effective in reducing dyspnea and improving respiratory function. Device-guided breathing exercises decreased blood pressure, improved sleep quality, and strengthened respiratory muscles. IMT, an efficient method, is suggested for inclusion in rehabilitation programs due to its capacity to increase physical activity, exercise capacity, and peripheral muscle strength, enhance HrQoL and respiratory function, and alleviate dyspnea. Also, the efficacy of IMT should be investigated with different training protocols such as endurance IMT or functional IMT in HT patients.

Integrative medicine considerations for convalescence from mild-to-moderate COVID-19 disease

The majority of individuals infected with SARS-CoV-2 have mild-to-moderate COVID-19 disease. Convalescence from mild-to-moderate (MtoM) COVID-19 disease may be supported by integrative medicine strategies. Integrative Medicine (IM) is defined as healing-oriented medicine that takes account of the whole person, including all aspects of lifestyle. Integrative medicine strategies that may support recovery from MtoM COVID-19 are proposed given their clinically studied effects in related conditions. Adoption of an anti-inflammatory diet, supplementation with vitamin D, glutathione, melatonin, Cordyceps, Astragalus and garlic have potential utility. Osteopathic manipulation, Qigong, breathing exercises and aerobic exercise may support pulmonary recovery. Stress reduction, environmental optimization, creative expression and aromatherapy can provide healing support and minimize enduring trauma. These modalities would benefit from clinical trials in people recovering from COVID-19 infection.

The beneficial effects of Qigong on elderly depression

Health Qigong, especially the Eight-Section Brocades (or Baduanjin), has been well established as an effective adjunct intervention to alleviate depressive symptoms of older adults. The easy to learn and safe format of health Qigong allows the promotion and employment by health care professionals to improve the physical and psychosocial wellness of older adults. The cultural relevance of Qigong practice enhances its popularity as a health maintenance practice in Chinese community. In general, the antidepressive effects of Qigong are put forward through psychosocial, physiological, and neurobiological mechanisms. More specific, the beneficial effects of Qigong can be further substantiated by findings of several research studies.

The Aerobic Capacity and Ventilatory Efficiency During Exercise in Qigong and Tai Chi Chuan Practitioners

The objective of this study was to compare cardiorespiratory responses to exercise among older Qigong participants, Tai Chi Chuan (TCC) practitioners and normal sedentary controls during cycle ergometry. Thirty-six community-dwelling men with a mean age of 59.1±6.6 years participated in this study. Each group (Qigong, TCC and control) included 12 subjects with matched age and body size. The Qigong group practiced Qigong regularly for 2.3±1.5 years; the TCC group practiced Yang TCC for 4.7±2.3 years. Heart rate (HR) responses were measured during the practice of Qigong and TCC. Additionally, breath-by-breath measurement of cardiorespiratory function was performed during the incremental exercise of leg cycling. The mean HR during Qigong and TCC practice was 91±5 bpm and 129±7 bpm, respectively. At the peak exercise and the ventilatory threshold (VeT), TCC group displayed highest oxygen uptake [Formula: see text], O2pulse and work rate among the three groups. The Qigong group also showed higher oxygen uptake and O2pulse than the control group. At the same relative exercise intensity, the Qigong group had the highest tidal volume among the three groups. In conclusion, Qigong and TCC show a beneficial effect to aerobic capacity in older individuals, but TCC displays a better training effect than Qigong due to its higher exercise intensity. However, Qigong can enhance breathing efficiency during exercise due to the training effect of diaphragmatic breathing.

To accomplish preliminary Qigong simulation state by acupuncture

OBJECTIVE

The purpose of the study was to find out how to enter the preliminary Qigong simulation state in a short period of time.

METHODS

This is a non-randomized, human experiment with healthy participants. A multi-channel digital physiological data recorder was used to detect whether the participants had entered the Qigong state. Participants were assisted to enter the Qigong state (relaxation, tranquility and naturalness) by being given the sore (sour) feeling produced by acupuncturing Hegu (LI4), and suggestions (repeating words "relax" and "heat" from the hypogastrium).

RESULTS

About 72.2% of the participants who had no Qigong experience were found entering the preliminary Qigong simulation state. Most of the physiological parameters measured after the participants entering the Qigong state showed significant changes compared with the baseline data.

CONCLUSION

This study revealed that acupuncture-made sore feeling is able to induce the participants to quickly enter the preliminary Qigong simulation state; hence this can be seen as no longer a limited phenomenon, but can be commonly applied to everybody.

External qigong therapy for women with breast cancer prior to surgery

The majority of patients with cancer use some form of complementary or alternative medicine. External qigong treatment (EQT), classified as a bioenergy therapy, is one such approach that patients combine with conventional medicine or, in some cases, use in place of conventional medicine. This study aimed to determine whether EQT could shrink breast cancer tumors and improve quality of life (QOL) in women with pathologically confirmed breast cancer awaiting surgery. A total of 9 women with pathologically confirmed breast cancer were recruited from large cancer centers in the United States (n = 5) and China (n = 4). A single-arm pre/post design was used. Each patient underwent 5 consecutive days of EQT, with each treatment lasting from 2 to 5 minutes. All treatments were performed by the same qigong master. Tumor measurements were made before and after the EQT sessions. Tumor assessments were conducted prior to study initiation and following the last EQT. Patients underwent both an ultrasound and mammogram (United States) or an ultrasound and magnetic resonance imaging (China). All patients also underwent physical breast examinations (PBEs) and completed QOL questionnaires before and after the last EQT. No clinical changes in tumor measurements from pre- to post-EQT were noted. There was also no suggestion of change in tumor size by PBE or change in QOL. Using the current

STUDY DESIGN

EQT also does not appear to have any effect on patient QOL. Because of the small sample size and working with only one qigong practitioner, to definitively determine the efficacy or lack of efficacy of EQT, a larger study with multiple qigong practitioners would need to be conducted.

Qi Gong exercises and Feldenkrais method from the perspective of Gestalt concept and humanistic psychology

This study describes two similar approaches to human movement: Qi Gong exercises and the Feldenkrais method. These systems are investigated in terms of Gestalt concepts and humanistic psychology. Moshe Feldenkrais created the concept known as Awareness Through Movement. This concept assumes that by becoming more aware of one's movements, one functions at a higher level. In similar ways to those using the Feldenkrais method, individuals may become more aware of their own movements by performing Qi Gong exercises: A therapeutic modality that facilitates mind-body integration. Qi Gong exercises commonly lead to increased personal awareness accompained by enhanced quality, fluency and smoothness of movement. These two methods of movement therapies are explored in terms of their relations with Gestalt concept and humanistic psychology.

Biopsychosocial effects of qigong as a mindful exercise for people with anxiety disorders: a speculative review

In view of the inadequacies of mainstream treatments for anxiety disorders, we suggest that qigong, an ancient oriental mindful exercise, may be a useful adjunctive treatment. We base this on a biopsychosocial model for health. Evidence suggests that the benefits of exercise on personal well-being can be explained using six theories: cognitive behaviour; distraction; social interaction; cardiovascular fitness; amine; and endorphin theories. To date, not much has been done to employ these theories to analyze the benefits of mindful exercises. We try here to reorganize these theories into psychosocial and physiologic perspectives and integrate them with the "mind regulation," "body regulation," and "breath regulation" components of qigong. We propose, because of its potential therapeutic effects, that qigong can be considered as an alternative therapy to help meet the increasing demand of nonpharmacologic modalities in achieving biopsychosocial health for those suffering from anxiety in the general population.

Randomised controlled trial of qigong in the treatment of mild essential hypertension

Exercise and relaxation decrease blood pressure. Qigong is a traditional Chinese exercise consisting of breathing and gentle movements. We conducted a randomised controlled trial to study the effect of Guolin qigong on blood pressure. In all, 88 patients with mild essential hypertension were recruited from the community and randomised to Goulin qigong or conventional exercise for 16 weeks. The main outcome measurements were blood pressure, health status (SF-36 scores), Beck Anxiety and Depression Inventory scores. In the qigong group, blood pressure decreased significantly from 146.3+/-7.8/93.0+/-4.1 mmHg at baseline to 135.5+/-10.0/87.1+/-7.7 mmHg at week 16. In the exercise group, blood pressure also decreased significantly from 140.9+/-10.9/93.1+/-3.5 mmHg to 129.7+/-11.1/86.0+/-7.0 mmHg. Heart rate, weight, BMI, waist circumference, total cholesterol, renin and 24 h urinary albumin excretion significantly decreased in both groups after 16 weeks. General health, bodily pain, social functioning and depression also improved in both groups. No significant differences between qigong and conventional exercise were found. In conclusion, Guolin qigong and conventional exercise have similar effects on blood pressure in patients with mild hypertension. While no additional benefits were identified, it is nevertheless an alternative to conventional exercise in the nondrug treatment of hypertension.

Psychological and physiological characteristics of a proposed object-referral/self-referral continuum of self-awareness

This research extends and confirms recent brainwave findings that distinguished an individual's sense-of-self along an Object-referral/Self-referral Continuum of self-awareness. Subjects were interviewed and were given tests measuring inner/outer orientation, moral reasoning, anxiety, and personality. Scores on the psychological tests were factor analyzed. The first unrotated PCA component of the test scores yielded a "Consciousness Factor," analogous to the intelligence "g" factor, which accounted for over half of the variance among groups. Analysis of unstructured interviews of these subjects revealed fundamentally different descriptions of self-awareness. Individuals who described themselves in terms of concrete cognitive and behavioral processes (predominantly Object-referral mode) exhibited lower Consciousness Factor scores, lower frontal EEG coherence, lower alpha and higher gamma power during tasks, and less efficient cortical preparatory responses (contingent negative variation). In contrast, individuals who described themselves in terms of an abstract, independent sense-of-self underlying thought, feeling and action (predominantly Self-referral mode) exhibited higher Consciousness Factor scores, higher frontal coherence, higher alpha and lower gamma power during tasks, and more efficient cortical responses. These data suggest that definable states of brain activity and subjective experiences exist, in addition to waking, sleeping and dreaming, that may be operationally defined by psychological and physiological measures along a continuum of Object-referral/Self-referral Continuum of self-awareness.

Effects of Qigong on blood pressure, blood pressure determinants and ventilatory function in middle-aged patients with essential hypertension

This study was designed to measure changes in blood pressure (BP), urinary catecholamines and ventilatory functions of patients with mild essential hypertension after 10 weeks of Qigong (Shuxinpingxuegong). Fifty-eight patients volunteered to participate in this study and were randomly divided into either a Qigong group (n = 29), or a control group (n = 29). Systolic blood pressure and diastolic blood pressure decreased significantly in the Qigong group such that both became significantly lower after 10 weeks in the Qigong than in the control group. Also, there was a significant reduction of norepinephrine, metanephrine and epinephrine compared to baseline values in the Qigong group. The ventilatory functions, forced vital capacity and forced expiratory volume per sec, were increased in the Qigong group but not the control. These results suggest that Qigong may stabilize the sympathetic nervous system is effective in modulating levels of urinary catecholamines and BP positively, and in improving ventilatory functions in mildly hypertensive middle-aged patients.

Modulation of neuroendocrinological function by psychosomatic training: acute effect of ChunDoSunBup Qi-training on growth hormone, insulin-like growth factor (IGF)-I, and insulin-like growth factor binding protein (IGFBP)-3 in men

The neuroendocrine system is regarded as the major link between the psychological state and the immune system in man. The present study was undertaken to examine the acute effect of ChunDoSunBup Qi-training, a traditional psychosomatic training, on the plasma level of growth hormone (GH), insulin-like growth factor (IGF)-I and insulin like growth factor binding protein (IGFBP)-3 in young men. To characterize the plasma level of hormones and the pattern of IGFBP-3 at pre- (-10 min), mid-time (40 min), and immediately after (post-time, +10 min) Qi-training, radioimmunoassay (RIA) and western ligand blot (WLB) analysis were used. The plasma level of GH at the mid-time was significantly increased (P<0.05) compared to the level at pre-time of Qi-training. The plasma level of IGF-I was also increased at mid-time (P<0.05) and immediately after Qi-training. There was a significant correlation between the levels of GH and IGF-I immediately after Qi-training (r=0.69, P<0.01). In this study, the change of IGFBP-3 among the several IGFBPs was determined. There was a relative shift in IGFBP-3 for the 43-kDa fraction during mid-time of Qi-training (P<0.05). These results suggest that Qi-training influences the growth hormone, IGF-I and IGFBP-3 status via brain-target organ axis in men.

Effect of Qi-training on blood pressure, heart rate and respiration rate

To examine the physiological effects of Korean traditional Qi-training, we investigated the changes in blood pressure, heart and respiratory rates before, during and after ChunDoSunBup (CDSB) Qi-training. Twelve normal healthy CDSB Qi-trainees (19-37 years old; trained for 1.3 +/- 0.2 years; 9 men and 3 women) volunteered to participate in this study. Heart rate, respiratory rate, systolic blood pressure and rate-pressure product were significantly decreased during Qi-training. From these results, we suggest that CDSB Qi-training has physiological effects that indicate stabilization of cardiovascular system.

Acute effects of chundosunbup qi-training on blood concentrations of TSH, calcitonin, PTH and thyroid hormones in elderly subjects

The present study investigated how the systemic treatment of a programmed exercise, ChunDoSunBup (CDSB) Qi-training, affects the secretion of thyroid and parathyroid hormones in elderly subjects (10 male and 5 female). Plasma concentrations of thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), parathyroid hormone (PTH), ionized calcium, and calcitonin were determined. CDSB Qi-training induces a slight increase in TSH. Both T4 and T3 were increased at the mid-time of CDSB Qi-training (p < 0.05). There were significant correlations only between T3 and T4 at mid-training. This shows that increase in the plasma level of T3 was associated with the secretion of T4. The plasma concentrations of calcitonin and PTH were increased at mid-time and post-time of CDSB Qi-training. But ionized calcium was decreased slightly by CDSB Qi-training. These results suggest that Qi-training modulates the secretion of thyroid hormones, calcium metabolism, and parathyroid hormones in the elderly. However, whether the long-term practice of CDSB Qi-training might change bone metabolism and have longitudinal effects on the thyroid hormone of the elderly need further investigation.

Multisite electromyographic analysis of therapeutic touch and qigong therapy

The influence of complementary healing treatment on paraspinal electromagnetic activity at specific neuromuscular sites was examined in an exploratory pilot study that used a multisite surface electromyographic (sEMG) assessment procedure. The study was a replication and extension of previous research that indicated that complementary healing had a significant effect in normalizing the activity of the "end organ" for the central nervous system (CNS). Multisite sEMG electrodes were placed on the frontalis, cervical (C4), thoracic (T6), and lumbosacral (L3) paraspinals of 44 subjects who were divided into three groups: (1) students/patients of a Qigong practitioner (n = 16); (2) students/patients of a therapeutic touch (TT) practitioner (n = 14); and (3) nonbelievers in complementary healing (n = 14). A traditional ABAC experimental design was used with each subject evaluated for one 20-minute session that included four 5-minute segments. The purpose of this study was to measure the variable energizing effect of Qigong therapy along with the anecdotally and experimentally established relaxation effect of TT therapy relative to patient belief and expectancy. Treatment sessions consisted of Qigong and a modified form of TT intervention for all three groups. Due to the double-blind nature of the study, however, group 1 subjects were aware of only the Qigong intervention; group 2 subjects were aware of only the TT intervention, and group 3 subjects were informed that the study was designed to assess the neuromuscular activity of individuals in a seated position. The results indicated a statistically significant rise in electromagnetic activity for group 1 during the Qigong intervention segment (p < .024). Group 2 demonstrated a modest although overall nonsignificant decrease in multisite sEMG levels for both treatment protocols, whereas group 3 exhibited relatively consistent neuromuscular activity for both control and treatment segments. The results of this study are considered preliminary in nature, however, due to the potential influence of several confounds including psychophysiological factors, established behavior patterns, and the possibility for information transfer due to sensory cues.
