Background:: The heart is the central organ of the circulatory system which maintains the flow of blood along with the transport of nutrients to different cells and tissues. A well-functioning cardiac state is a complicated mode of changeability. A healthy heart is not only about oscillation as the rhythmometer is not the same in every circumstance. Heart rate shows variations so that it can be regulated according to psychophysiological conditions to maintain the effect of the internal-external stimulus. Objective:: The main objective of this review is to provide a piece of all-inclusive information about heart rate variability (HRV) and different variables affecting HRV. The direct interconnection among factors and so that HRV can be used in clinical practices. Methods:: This review article contains a detailed survey of literature about HRV available in different online sources such as; Google Scholar, Science Direct, PubMed, and Web of Science, etc. In this review, the authors have focused on the role of the autonomic nervous system in the regulation of HRV and the role of various factors affecting HRV. Results:: The variation in the time between two heartbeats is termed as HRV. It is one of the indicators of many pathological conditions related to cardiovascular health. It provided reliable information about the interaction of the sympathetic and parasympathetic nervous systems. The analysis of the variation of heart rate is a well-known non-invasive technique to identify the functioning of the autonomic nervous system. The autonomic nervous system (ANS) depends on the sympathetic and parasympathetic nervous system for transferring information. The cardio-accelerating center, lungs, and non-striated muscles are innervated by cardiac sympathetic nerves. This division of ANS latches upon the heart accordingly via the cervicothoracic ganglion and vagus nerve. It is found that cardiac normal variability depends upon this stimulation towards the sinoatrial node (pacemaker) which can be evaluated by analyzing the HRV. In human- based studies, it has been found that low level of HRV is one of the main causes of death rate among adults. Hence, HRV helps in identifying the risk of cardiac diseases and the state of ANS. Conclusion:: The heart plays a vital role in the human body and the well-functioning of the cardiac system is the need for a healthy life. The heart contains its nervous system termed as neurocardio system in which ANS plays a key role in which the sympathetic and parasympathetic system interplay to regulate HRV. High HRV is associated with healthy condition while low HRV is associated with pathological conditions. The HRV is influenced by various variables such as; pathological, physiological, psychological, environmental factors, lifestyle factors, and genetic factors, etc.

Autonomic Nervous

Introduction. Although its neurophysiological effects have not been fully elucidated, current evidence suggests the clinical effectiveness of spinal manipulation. Different studies suggest that manual therapy induces changes in the autonomic nervous system (ANS). Recent studies showed that mobilization produced a sympatheticexcitatory effect. However, studies using thrust manipulation appeared to be less consistent in their results.Objectives. The main objective of this review was to evaluate whether spinal manipulation induces effects on the ANS. Another objective was to correlate the changes in the measured variables with the activation or inhibition of the sympathetic or parasympathetic nervous system and with the level of spinal manipulation.Materials and methods. We performed a literature search in the following databases: PubMed, PEDro, CINAHL and OVID, using the keywords «Manipulation, spinal» and «Autonomic Nervous System». The PEDro scale was used to assess the methodological quality.Results. Nine studies met the inclusion criteria. Six trials measured cardiovascular function indicators (blood pressure, heart rate, Heart Rate Variability). Three other trials measured the pupil reaction. In most studies, cervical or upper thoracic region was manipulated.Conclusions. Our review does not provide definitive evidence of the effects of spinal manipulation on the ANS. However, most studies observed the existence of autonomic effects by modifying parameters such as blood pressure or Heart Rate Variability after manipulation. Increased parasympathetic activation probably occurs after cervical and lumbar treatment and increased sympathetic activation after dorsal treatment.

Effect Of Treatment

AbstractThe autonomic nervous system controls the smooth muscles of the internal organs, the cardiovascular system and the secretory function of the glands and plays a major role in the processes of adaptation. Heart rate variability is a non-invasive and easily applicable method for the assessment of its activity. The following review describes the origin, parameters and characteristics of this method and its potential for evaluation of the changes of the autonomic nervous system activity in different physiological and pathological conditions such as exogenous hypoxia, physical exercise and sleep. The application of heart rate variability in daily clinical practice would be beneficial for the diagnostics, the outcome prognosis and the assessment of the effect of treatment in various diseases.

Introduction: To study the effect of myofascial techniques applied to the cranial regionon the behavior of autonomic nervous system (ANS), using the analyses of heart ratevariability. Method: This is a clinical trial study accomplished with 66 healthy subjects(33 male and 33 female). Myofascial techniques applied to the cranial area usingcraniosacral therapy were executed on the individuals. The Nerve-Express system, afully automated system, was used before and after the application of the techniques toquantitatively assess the autonomic function based on heart rate variability analysis. Toverify the existence of differences among the dependent variables the Wilcoxon SignedRanks Test was used and o Mann-Whitney Test was applied in order to compare theindependent variable. Results: It was observed a statistically significant increase, inthe values of parasympathetic nervous system (PSNS), after the application of thetechnique. The quantitative values of sympathetic nervous system (SNS) decreased ordid not modify in female group. This profile in female group was statistically significantalthough in the male group the miofascial mobilization did not modify the values ofSNS. The quantitative values of SNS and PSNS behaved equal relatively in both studiedgroups, not being significant statistically the difference between the male and femalegroups. Conclusion: These results suggest that the myofascial technical applied to thecranial area by craniossacral therapy is able to promote alterations in the behavior ofANS, generally, increasing PSNS and decreasing SNS.

This study aims to examine electro-acupuncture stimulation (EA) assisted therapy with analysis of heart rate variability to understand autonomic nervous activity variability (ANAV) and to track the changes in female patients with constipation. The average ages were 42±12 years old. The participants were divided by a single-blind and randomized trial into two groups: the electro-acupuncture-point group, and the non-electro-acupuncture-point group. Both of the groups had eight treatments, once a week. For the electro-acupuncture (EA) group, needles were inserted into their Zusunli (ST36), Shangiuxu (ST37), Tiensu (ST25), Shueidao (ST28), Guanyuan (CV4) and Qihai (CV6) points. For the sham electro-acupuncture (SA) group, needles were inserted into acu-points that were not the ones mentioned for the EA group. While inserting needles, needles were inserted lightly into the participants' skin and removed quickly (mock Transcutaneous Electrical Nerve Stimulation, TENTS). After an eight-week treatment period, the autonomic nervous system activities of the SA group did not show significant differences in their heart rate variability. However, the autonomic nervous system activities of the EA group had continuously increased after each session. The normalized high frequency powers (nHFP) of their autonomic nervous system activities were 26.79 in the first week, and they increased to 32.28 in the fourth week. In the eighth week, their nHFP had increased to 37.60 (p < 0.05). The normalized low frequency power (nLFP) was 30.81 in the first week. However, it decreased to 25.98 after three weeks of treatment. After the eight-week treatment period, the nLFP decreased to 24.84 (p < 0.05). After the eight-week treatment, the control group did not appear to undergo any physiological change, while the constipation had been improved for the experimental group. It was found that the activation of parasympathetic nervous system in the experimental group increased after the eight-week treatment. The effects of such a result on the enhancement of the activation of parasympathetic nervous system and the improvement of constipation should be further discussed.

AbstractThis study explored the effect of long naps on handball-related performance and assessed the role of the cardiac autonomic nervous system in this process. Eleven male collegiate handball players performed a repeated sequential trial consisting of a 20-m consecutive turnaround run, 10-m run with a load, and shooting the ball into a target. Participants were allocated randomly and sequentially to have a short (20 minutes) nap, long (60 minutes) nap, or no nap. The Pittsburgh Sleep Quality Index was used to assess regular sleep quality. Subjective sleepiness before and after napping was measured using the Karolinska Sleepiness Scale. Heart rate variability was recorded to assess cardiac autonomic nervous function during napping. The Pittsburgh Sleep Quality Index score was correlated with shot accuracy only after long naps (ρ=0.636, r=0.048). A negative correlation was observed between the root mean square of successive differences and average load run time (ρ=−0.929, p<0.001). Long napping was associated with a significant benefit on performance in athletes with poor sleep quality, implying a role of the autonomic nervous system in this regard. Our findings indicate the effect of sleep quality on the endurance and resistance of handball players.
