Objective. To explore the value of biological image technology in improving athletes’ motor skills. Methods. Golfers were given biofeedback relaxation training, and the variation trend and influence of biofeedback training on athletes’ heart rate variability were explored by monitoring and feedback evaluation of athletes’ heart rate variability. Results. Biofeedback relaxation training can help athletes improve the balance of sympathetic nerve and parasympathetic nerve, effectively inhibit the activity of sympathetic nerve, enhance the tension, effectively increase the heart rate variability of athletes, and strengthen the ability of psychological relaxation. Conclusion. Part of the research results show that biofeedback training can enhance athletes’ athletic performance and improve their athletic performance to a certain extent.

Previous research has suggested a relationship between low-frequency power of heart rate variability (HRV; LF in normalized units, LFnu) and muscle sympathetic nerve activity (MSNA). However, investigations have not systematically controlled for breathing, which can modulate both HRV and MSNA. Accordingly, the aims of this experiment were to investigate the possibility of parallel responses in MSNA and HRV (LFnu) to selected acute stressors and the effect of controlled breathing. After data were obtained at rest, 12 healthy males (28 ± 5 yr) performed isometric handgrip exercise (30% maximal voluntary contraction) and the cold pressor test in random order, and were then exposed to hypoxia (inspired fraction of O2 = 0.105) for 7 min, during randomly assigned spontaneous and controlled breathing conditions (20 breaths/min, constant tidal volume, isocapnic). MSNA was recorded from the peroneal nerve, whereas HRV was calculated from ECG. At rest, controlled breathing did not alter MSNA but decreased LFnu ( P < 0.05 for all) relative to spontaneous breathing. MSNA increased in response to all stressors regardless of breathing. LFnu increased with exercise during both breathing conditions. During cold pressor, LFnu decreased when breathing was spontaneous, whereas in the controlled breathing condition, LFnu was unchanged from baseline. Hypoxia elicited increases in LFnu when breathing was controlled, but not during spontaneous breathing. The parallel changes observed during exercise and controlled breathing during hypoxia suggest that LFnu may be an indication of sympathetic outflow in select conditions. However, since MSNA and LFnu did not change in parallel with all stressors, a cautious approach to the use of LFnu as a marker of sympathetic activity is warranted.

Abstract Background Cardiovascular disease is one of the leading causes of death globally with hypertension being a primary cause of premature death from this disease process. Individuals with a family history of cardiovascular disease and hypertension are at a greater risk for developing the same sequela. Autonomic cardiac control is important in the level of cardiac function. One intervention that is effective in improving cardiovascular function is heart rate variability biofeedback training. The purpose of our study was to determine the effectiveness of heart rate biofeedback training on HRV and blood pressure in individuals with a family history of cardiovascular disease. Methods Thirty-four participants (76.5% female, 22.7 ± 4.3 years) completed a baseline assessment and training using an established short-term HRV protocol followed by two weeks of at-home paced breathing employing a smartphone application. The participants were then reassessed in a biofeedback clinic. Results The participants physiological measures showed a significant increase in means between pre and post intervention of SDNN (t (32) = 2.177, p =.037) and TP, (t (32) = 2.327 p = .026). Correlation noted a medium effect on diastolic blood pressure and high frequency heart rate variability, F, r = .41, n =33, p < .05. A multiple regression with all predictor variables in the model found no significance with diastolic and systolic blood pressure. Conclusions The findings from this pilot study demonstrated that a two-week paced breathing intervention may assist in reducing heart rate and diastolic blood pressure while improving heart rate variability.

Autonomic dysfunction is one of the predictors of poor outcome in patients with acute ischemic stroke. We compared the heart rate variability (HRV) during early mobilization in patients with or without neurological deterioration (ND). We enrolled 7 acute ischemic patients with ND and 14 without ND and measured their HRV in the rest and mobilization by electrocardiography. There was a significant difference in sympathetic nervous activity during mobilization between the 2 groups. However, no significant differences in blood pressure, heart rate, and parasympathetic nerve activity were observed. In patients with acute ischemic stroke, it is likely that the increase in sympathetic nervous activity during mobilization is associated with ND.

AbstractThe aim of this study was to determine whether non-invasive heart rate variability (HRV) recordings can be used to monitor training exercises and to estimate athletic performance. Thus far, condition and performance have been evaluated with lactate test procedures and spirometry. Several tests were conducted to determine the relationship of data from lactate test samplings, spirometry and HRV recordings. Four groups of professional athletes in different disciplines such as ball sports (n=15), martial arts (n=17), endurance sports (n=8) and hobby athletes (n=6) underwent a standardized treadmill or bicycle ergometer step test while increasing load rates, e.g. 2 km/h or 20-50 Watt every 3.5 minutes, synchronized with standardized series of lactate test sampling, spirometry and ECG recording. An inclusion criterion for all athlete groups was a minimum training frequency of an hour, five days a week focusing on continuous performance improvement. Evidence shows that offline analysis of ECG data allows conclusions on actual individual athletic performance without the need for complex instrumentation and laboratory environment. The total power parameter of the HRV reaches a plateau phase in all tested subjects and this plateau phase reaches zero near the 2 mmol threshold of lactate concentration in all subjects recorded on a bicycle ergometer. Nine out of ten subjects measured on the bicycle ergometer had negatively correlating data of lactate concentration and total power of HRV (α < 0.05). Lactate measurements using treadmills require resting periods for blood sampling. As the HRV increases instantly in these resting periods, the use of bicycle ergometers, where no testing breaks are needed, is recommended for further research.

Recent research has noted a significant overlap between symptoms of posttraumatic stress disorder (PTSD) and postconcussion syndrome (PCS). In this article, an argument is made for providing a specialized form of heart rate variability biofeedback that allows for the physiological discharge of trauma among patients who present with comorbid symptoms of PTSD and PCS. Recommendations for clinicians who encounter the manifestation of trauma during their work with PCS patients are provided. Future areas of heart rate variability biofeedback research among PCS and PTSD populations are further delineated.

This paper discusses the clinical applications of heart rate variability (HRV) data in the treatment of clients who have experienced traumatic brain injuries (TBIs). In the authors' clinical practice, HRV data is collected at the initial assessment, at progress assessments, and again after the completion of a course of neurofeedback combined with HRV biofeedback treatment. This paper describes HRV seen in healthy individuals compared to HRV in individuals known to have experienced a TBI. Three clinical case examples are discussed that explore the changes in heart rate variability following traumatic brain injury as well as improvements noted during, and following, a course of neurofeedback combined with HRV biofeedback training. The cases illustrated in this paper demonstrate the impressive changes in heart rate variability that can occur following a traumatic brain injury and also highlight how neurofeedback combined with biofeedback training can be used to improve heart rate variability and ameliorate related cognitive symptoms.

Symptomatic Cancer

10099 Background: Late effects of cancer and its treatment include pain, fatigue, stress, and depression all mediated by autonomic dysfunction. Heart Rate Variability (HRV) coherence is an established measure of autonomic dysfunction. Cancer survivors have lower HRV coherence than normal controls. HRV biofeedback (HRV-B) training improves HRV coherence, restores autonomic health, and reduces the above symptoms. This report describes a feasibility study of HRV-B in symptomatic cancer survivors. Methods: In a randomized, waitlist controlled, clinical trial, 179 were screened, 34 enrolled and 31 completed the protocol. Participants in the intervention arm received weekly HRV-B training up to six weeks. Outcome measures assessed at baseline (pre) and after week six (post) included HRV coherence plus Insomnia Symptom Questionnaire (ISQ), Suscro Distress Inventory (SDI), Brief Pain Inventory (BPI), Multi-Dimensional Fatigue Inventory (MFI), Perceived Stress Scale (PSS) and Beck Depression Inventory II (BDI-II). Results: See table below. Conclusions: Delivering HRV Biofeedback training to cancer survivors is feasible at our Cancer Institute. This pilot study provides preliminary evidence that HRV-B for cancer survivors improves HRV coherence and reduces insomnia, pain, fatigue, depression, and stress. The intervention has great potential and further research is indicated. [Table: see text]
