Craniosacral Therapy

Introduction: The Craniosacral Therapy uses tender and accurate touches to diagnose and treat the craniosacral system. The Mixed Martial Arts athletes are exposed at risk of injury during competitions, which can affect your welfare. The Craniosacral Therapy improves the functioning of the Central and Autonomic Nervous System, that promotes relaxation, sense of welfare and homeostasis in the body. Objective: to evaluate the effect of Craniosacral Therapy in welfare and Autonomic Nervous System in Mixed Martial Arts fighters. Method: We conducted a case study by analyzing the heart rate and general welfare of 05 Mixed Martial Arts fighters, eight sessions with Craniosacral Therapy, using respectively a frequency Polar RS800 and a Range of Subjective Well-Being for collection data, posteriorly it was submitted to the calculation of mean and standard deviation and "T Studant" test to compare the data before and after the treatments. Results: The initial evaluation of the athletes showed a high subjective well-being, that remained after the therapy. There was a statistically significant increase in one of the athletes with respect to positive affect (from 4.048 ± 0.5896 to 4.429 ± 0.5071). As for the negative affects three increased the score. There was a statistically significant reduction (p <0.001) between the initial and final heart rates in each service, with averages of 68.50 and 63.28 respectively. Conclusion: The Craniosacral Therapy increases the activity of the parasympatic nervous system, promoting decreased heart rate, providing better coronary flow and that alone is not sufficient to determine an increase or decrease of well-being.

Shed Light

Physiologist Claude Bernard lived in a time when very little was known about the mechanisms underlying physiologic findings, and he had ample access to clues garnered from observing machines. Let's consider homeostasis (a concept championed by Bernard), an example for which an engineered machine shed light on a fundamental principle of physiology. Homeostasis is simply the tendency of the body to maintain important physiologic variables (eg, heart rate, blood pressure, PACO2) at constant, preset values. An example is a simplified mechanical governor that could be used to regulate the rotational speed of a steam engine shaft. ‘Autoregulate’ might be a more apt word because the governor performs without external help or guidance, provided it is designed and built properly. It doesn't take much imagination to see an analogy between the mechanical governor and the autonomic nervous system. Both maintain specific variables at a constant set point through a process of feedback loops.

Modern games consists of digital gaming consoles that involves interaction with a user and has an interface to generate visual feedback through 2D/3D monitor. These games have several psychological side effects like loss of spatial awareness, back pains, insomnia, addiction, aggression, stress, and hypertension. Virtual reality (VR) Gaming is one of the most emerging and novel technologies in the field of entertainment. Evaluation of this new technology has become important in order to analyze the effects of its predecessors (2D and 3D gaming). The main focus of this paper is on detection of stress levels in individuals due to VR gaming and classify them depending on their sympathetic and parasympathetic dominance. This is done through acquisition of electrocardiogram (ECG) and photo plethysmograph signals (PPG) signals and extracting their time domain and frequency domain features before, during and after gaming (Fatma Uysal and Mahmut Tokmakçi, 2018. Evaluation of stress parameters based on heart rate variability measurement. Department of Biomedical Engineering, Erciyes University, Kayseri, Turkey. [email protected], [email protected]., da Silva1, A.G.C.B., Arauj, D.N., et al, 2018. Increase in perceived stress is correlated to lower heart rate variability in healthy young subjects. Departamento de Fisioterapia, Universidade Federal do Rio Grande do Norte, Natal, Rio Grande do Norte, Brazil. s/n., 81531–980, Curitiba, Parana, Brazil. E-mail: [email protected].). The physiological signal variation is analyzed by performing Heart Rate Variability (HRV) analysis over ECG signals which is one of the fast emerging methods in non-invasive research and clinical tools for assessing autonomic nervous system function (Juan Sztajzel, 2004. Heart rate variability: Aa non-invasive electrocardiographic method to measure the autonomic nervous system. Cardiology Center and Medical Policlinics, University Hospital, Geneva, Switzerland, SWISS MED WKLY 2004;134:514–522. www.smw.ch). Pulse-transmissiontime-variability (PTTV), which is extracted, has high coherence with heart rate variability and is also used as an objective measure of stress. In this paper we obtain the response of an individual during VR gaming and correlate them with the HRV/PTT parameters. The game chosen for the data acquisition was ‘VR city view rope crossing-360 android VR,’ during which data recording is done. It was found that there was a quantitative increase in physiological stress when individuals were exposed to virtual high heights in comparison with time relative to unaltered viewing. Mean Heart rate showed a significant increase during gaming for both boys and girls which indicates that the body is under the influence of a sympathetic activity like a physical exercise.

Abstract Background: Acute bouts of ultra-endurance exercise may cause an acute reduction in cardiac function, causing a physiological cascade which releases cardiac biomarkers. This study set out to determine the cardiac stress and recovery of participation in a three-day ultra-endurance mountain biking event of athletes using heart rate variability (HRV) as an outcome measure. Sixteen healthy participants (male and female) participating in a three-day ultra-endurance mountain biking event underwent a five-minute resting electrocardiography (ECG) recording in a supine position. Heart rate variability measurements were recorded two days before the race (baseline testing), after each race day, and at 24-hour post-event (recovery). Results: Time-domain and frequency domain measures showed significant (p≤0.05) changes from baseline in HRV parameters after each race day. The significant changes in HRV parameters reflected an increase in sympathetic activity after each day of the event. Our data revealed that the mean HR and RR variability variables did not return to baseline value after 24-hours of recovery, reflecting autonomic nervous system dysfunction, and that changes persisted for at least 24-hours post-event.Conclusion: Our study shows that competing in an ultra-endurance mountain bike event led to diminished vagal activity and a decrease in HRV throughout the event and persisted for at least 24-hours post-event. The body was under continuous sympathetic dominance during rest as well as during each day of racing, implying each race day can be considered a physiological stress. This may, in turn, cause a disturbance in homeostasis and an increase in autonomic nervous system dysfunction. This has implications for further research, including dysrhythmia risk, and monitoring of athletes in advising a return to strenuous activity.

The biological clock, the suprachiasmatic nucleus (SCN), is essential for our daily well-being. It prepares us for the upcoming period of activity by an anticipatory rise in heart rate, glucose and cortisol. At the same time the 'hormone of the darkness', melatonin, decreases. Thus, the time-of-day message penetrates into all tissues, interestingly not only by means of hormones but also by a direct neuronal influence of the SCN on the organs of the body. The axis between the SCN and the paraventricular nucleus of the hypothalamus (PVN) is crucial for the organization/synchronization of the neuroendocrine and autonomic nervous system with the time of day. This SCN-neuroendocrine PVN axis takes care of a timely hormonal secretion. At the same time, the SCN-autonomic PVN axis fine-tunes the organs by means of the autonomic nervous system for the reception of these hormones. Finally, the similar organization of the projections of the human SCN as compared with that in the rodent brain suggests that these basic principles of neuroendocrine autonomic interaction may also be true in the human. The physiological data collected in humans thus far seem to support this hypothesis, while pathological changes in the SCN of humans suffering from depression or hypertension indicate a role for the SCN in the etiology of these diseases.

Yogic Breathing

Yogic breathing techniques are fundamental to the physical and mental practice of yoga. They are closely connected to meditation, which involves the observation of breath. There are many yogic techniques based on the active regulation of the breath. Breathing practices influence many processes in the body, e.g. heart rate variability, and the mind, e.g. relaxation and stress, through their impact on the autonomic nervous system. This study intended to investigate differential effects of four yogic breathing techniques: (1) <em>ujjayi</em>—relaxation through slowing down the breath, (2) paced breathing—enhancement of concentration by following a precise protocol of slowdown breathing, (3) <em>kapalabhati</em>—raising wakefulness by mild hyperventilation, and (4) alternate nostril breathing—balancing the autonomic nervous system by alternating breath between the two nostrils. This study was conducted on 36 participants, who learned each technique within two weeks of an eight-week program and practiced them daily. After each technique, mindfulness, perceived stress, and physical well-being were assessed based on questionnaires. Ujjayi breathing, showed a relaxing effect, reduced stress, increased peacefulness, and the feeling of being at ease/leisure. Paced breathing resulted in a greater awareness of inner experiences. Kapalabhati showed a significant increase in vitality and joy of life, and alternate nostril breathing showed no hypothesis-compliant changes. The findings of this study suggest several beneficial and differential effects of these breathing techniques; therefore, they could be employed as tools for self-regulation in therapeutic contexts.

The benefits of exercise have been widely recognised for a long time. Exercise increases heart rate, in turn facilitating the effective flow of oxygen and blood around the body and enabling the muscles to use this oxygen and blood in economically beneficial ways. Dr Hideo Nakamura, Department of Health Promotion and Sports Science, Osaka Electro-Communication University, Japan, is exploring the importance of lower limb compression socks for measuring autonomic nervous system (ANS) activity. ANS is a key regulator of the cardiovascular system and helps regulate heart rate and blood pressure. Nakamura is filling a research gap as there is little scientific consensus on the effects. A key focus for Nakamura and his team is on the significance of compression socks for sports to measure ANS activity with heart rate variability during exercise. Nakamura is building on previous studies utilising Tone-Entropy analysis, which is effective as it has high reproducibility and high reliability. Using this method, the researchers will explore mental stress, effects of exercise, pharmacological effects and meditation, among other things. The team used a bicycle ergometer to observe heart rate and ANS activity and found that rhythmic exercise could promote improved blood flow in the veins through compression of the lower limbs. Ultimately, the team hopes to define the subtle differences in parasympathetic nervous activity in individuals wearing compression socks.
