International Review of Sport and Exercise Psychology, Год журнала: 2022, Номер unknown, С. 1 - 75

Опубликована: Июль 7, 2022

Sport and Exercise Psychology (SEP) often adopts physiological markers in theory practice, one measure receiving increasing attention is heart rate variability (HRV). This paper aimed to provide a scoping review of the use HRV within SEP. The protocol was made available on Open Science Framework. Study inclusion criteria were examination SEP, using athletes or healthy populations, peer-reviewed published English. Exclusion non-peer reviewed work, animal studies, clinical conference papers. In February 2022 systematic search Web Science, PubMed Discus identified 118 studies (4979 participants) sport psychology (71) exercise (47). Risk bias assessed via Mixed Methods Appraisal Tool. A narrative synthesis revealed that range topics such as stress, overtraining, anxiety, biofeedback, cognitive performance, sporting performance. Three key limitations field discovered: limited application theoretical frameworks, methodological issues with measurement, differing interpretations results. Future research should vagally-mediated marker self-regulation adaptation consult relevant theories prior hypothesis development, follow guidelines for HRV.

Sports Performance and Breathing Rate: What Is the Connection? A Narrative Review on Breathing Strategies

Sports, Год журнала: 2023, Номер 11(5), С. 103 - 103

Опубликована: Май 10, 2023

Breathing is a natural and necessary process for humans. At the same time, respiratory pace frequency can vary so much, depending on status of subject. Specifically, in sports, breathing have effect limiting performance from physiological point view, or, other hand, regulate psychological athletes. Therefore, aim this narrative review to focus literature about aspects sports performance, merging these two because they are usually considered split, order create new integrated vision performance. Voluntary be divided into slow or fast (VSB VFB, respectively), their effects both parameters very different. VSB benefit athletes variety ways, not just physically but mentally as well. It help improve cardiovascular fitness, reduce stress anxiety, overall health well-being, allowing maintain concentration during training competition. VFB normal physical competition, away training, if it voluntary, cause feelings panic, dizziness, lightheadedness trigger response body, affecting athlete’s quality life. In summary, role should considered, although no definitive data available. The connection between still unclear, obtain benefits using strategies.

Cardiopulmonary and metabolic responses during a 2-day CPET in myalgic encephalomyelitis/chronic fatigue syndrome: translating reduced oxygen consumption to impairment status to treatment considerations

Journal of Translational Medicine, Год журнала: 2024, Номер 22(1)

Опубликована: Июль 5, 2024

Abstract Background Post-exertional malaise (PEM), the hallmark symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS), represents a constellation abnormal responses to physical, cognitive, and/or emotional exertion including profound fatigue, cognitive dysfunction, and intolerance, among numerous other maladies. Two sequential cardiopulmonary exercise tests (2-d CPET) provide objective evidence in ME/CFS but validated only studies with small sample sizes. Further, translation results impairment status approaches reduction are lacking. Methods Participants (Canadian Criteria; n = 84) sedentary controls (CTL; 71) completed two CPETs on cycle ergometer separated by 24 h. Two-way repeated measures ANOVA compared CPET at rest, ventilatory/anaerobic threshold (VAT), peak effort between phenotypes CPETs. Intraclass correlations described stability across tests, relevant data indicated status. A subset case–control pairs (n 55) matched for aerobic capacity, age, sex, were also analyzed. Results Unlike CTL, failed reproduce CPET-1 during CPET-2 significant declines work, time, $$\dot{\text{V}}$$ V ˙ e, O 2 , CO T HR, pulse, DBP, RPP. Likewise, observed VAT e/ PetCO 2, SBP. Perception (RPE) exceeded maximum criteria CTL both similar pairs. revealed greater variables test days owing ME/CFS. Lastly, signaled more severe CPET-1. Conclusions Presently, this is largest 2-d study substantiate impaired recovery following an exertional stressor. Abnormal post-exertional persisted indicating that fitness level does not predispose intolerance Moreover, contributions disrupted cardiac, pulmonary, metabolic factors implicates autonomic nervous system dysregulation blood flow oxygen delivery energy metabolism. The observable metabolism translate notably worsening Treatment considerations address tangible reductions physiological function proffered.

Neuromodulation Applied to Diseases: The Case of HRV Biofeedback

Journal of Clinical Medicine, Год журнала: 2022, Номер 11(19), С. 5927 - 5927

Опубликована: Окт. 8, 2022

The vagus or “wandering” nerve is the main branch of parasympathetic nervous system (PNS), innervating most internal organs crucial for health. Activity can be non-invasively indexed by heart-rate variability parameters (HRV). Specific HRV predict less all-cause mortality, lower risk and better prognosis after myocardial infarctions, survival in cancer. A non-invasive manner self-activating achieved performing a slow-paced breathing technique while receiving visual feedback one’s HRV, called HRV-biofeedback (HRV-B). This article narratively reviews biological mechanisms underlying role vagal activity vagally mediated hypertension, diabetes, coronary heart disease (CHD), cancer, pain, dementia. After searching literature HRV-B intervention studies each condition, we report effects on clinical outcomes these health conditions, evaluating methodological quality studies. Generally, levels evidence benefits high CHD, moderate poor diabetes Limitations future research directions are discussed.

Breathing Practices for Stress and Anxiety Reduction: Conceptual Framework of Implementation Guidelines Based on a Systematic Review of the Published Literature

Brain Sciences, Год журнала: 2023, Номер 13(12), С. 1612 - 1612

Опубликована: Ноя. 21, 2023

Anxiety and stress plague populations worldwide. Voluntary regulated breathing practices offer a tool to address this epidemic. We examined peer-reviewed published literature understand effective approaches implementation of these practices. PubMed ScienceDirect were searched identify clinical trials evaluating isolated breathing-based interventions with psychometric stress/anxiety outcomes. Two independent reviewers conducted all screening data extraction. Of 2904 unique articles, 731 abstracts, 181 full texts screened, 58 met the inclusion criteria. Fifty-four studies' 72 effective. Components ineffective evaluated develop conceptual framework factors associated reduction effectiveness. Effective breath avoided fast-only paces sessions <5 min, while including human-guided training, multiple sessions, long-term practice. Population, other paces, session duration ≥5 group versus individual or at-home not Analysis that did fit revealed extensive standing, interruptions, involuntary diaphragmatic obstruction, inadequate training for highly technical may render otherwise promising ineffective. Following evidence-based can help maximize benefits Future research is warranted further refine easily accessible intervention relief.

Scientific Reports, Год журнала: 2025, Номер 15(1)

Опубликована: Янв. 25, 2025

This global study analyzed data from the largest dataset ever studied in Heart Rate Variability (HRV) biofeedback field, comprising 1.8 million user sessions collected users of a mobile app during 2019 and 2020. We focused on HRV Coherence, which is linked to improved emotional stability cognitive function. Positive emotions reported by were associated with higher Coherence scores more stable frequencies. In contrast, negative exhibited lower dispersed frequency distributions. The most common was identified at 0.10 Hz. However, many highest levels fell within range 0.04 Most high (standard deviation < 0.012 Hz) their coherence frequencies session session, given increased increasing Coherence. insights gained this extensive suggest that instructing breathe deeper slower find rhythm that's comfortable, they naturally unique resonant frequency. findings provide strong foundation for future research development targeted interventions aimed enhancing physiological well-being through practices.
