  • Brief Biofeedback Intervention on Anxious Freshman University Students
    • Authors: Paulo Chaló; Anabela Pereira; Patrícia Batista; Luis Sancho
      Pages: 163 - 168
      Abstract: The increasing number of mental health disorders on university students represents a growing problem with negative impact on this population. Stress and anxiety issues are two of most predominant problems in this population and most campus health services have limited resources to face them. Research has provided evidence about biofeedback effectiveness. This study aims to verify the impact of a short duration biofeedback programme on freshmen university students with high levels of anxiety. A sample of 50 first-year students, with scores above percentile of 75 on STAI Y-2 were randomly selected and divided into two groups. Biofeedback Group took a 15 min session per week, over 8 weeks. No intervention was made on Control Group. Both groups were assessed before and after the biofeedback programme, and the results of the Trait Anxiety Scale and the Inventory of Stress for College Students were compared. The Biofeedback Group presented significant decreases in anxiety and stress values. Control Group presented slight and non-significant changes in scores. These results are consistent with previous studies and reinforce the evidence of biofeedback’s programmes as a valid solution to help students to manage their anxiety and stress.

  • Increased HPA Axis Activity and Serum Tryptophan in Naswar (Dipping
           Tobacco) Users: A Case–Control Study
    • Authors: Faiza Sajid; Samina Bano
      Pages: 169 - 178
      Abstract: Nicotine is the principal addictive agent present in Naswar, a smokeless dipping tobacco product. 5-Hydroxytryptamine (5-HT) has been implicated in the reinforcement properties of nicotine. Also, the hypothalamic–pituitary–adrenal (HPA) axis is of vital importance in evaluating the response to stress and nicotine addiction. The study aimed to evaluate serum tryptophan and cortisol levels in Naswar users in relation to addiction. Additionally, serum cotinine levels were also determined to assess daily nicotine exposure. The study comprised 90 healthy Naswar users and 68 non-tobacco users. Estimation of serum cortisol, tryptophan and albumin was carried out. From the Naswar user group, 20 were selected for the estimation of serum cotinine for which blood was drawn twice first in the morning and then in the evening. Serum tryptophan and cortisol levels in Naswar users were significantly raised compared to the control group. However, no difference in the levels of albumin between Naswar users and the control group were found. The mean cotinine values rose from the morning value of 366.0 ± 40.69 ng/ml (mean ± SEM) to an evening value of 503.1 ± 42.96 ng/ml that in turn is equivalent to consumption of 40 cigarettes. Elevated cortisol levels might constitute an important aspect of Naswar addiction. Additionally, raised levels of serum tryptophan in Naswar users could lead to raised concentration of 5-HT which also might be a significant factor contributing to Naswar addiction. Also, serum cotinine concentrations equivalent to an intake of about 40 cigarettes per day is quite alarming.

  • Pre-performance Physiological State: Heart Rate Variability as a Predictor
           of Shooting Performance
    • Authors: E. Ortega; C. J. K. Wang
      Abstract: Heart rate variability (HRV) is commonly used in sport science for monitoring the physiology of athletes but not as an indicator of physiological state from a psychological perspective. Since HRV is established to be an indicator of emotional responding, it could be an objective means of quantifying an athlete’s subjective physiological state before competition. A total of 61 sport shooters participated in this study, of which 21 were novice shooters, 19 were intermediate shooters, and 21 were advanced level shooters. HRV, self-efficacy, and use of mental skills were assessed before they completed a standard shooting performance task of 40 shots, as in a competition qualifying round. The results showed that HRV was significantly positively correlated with self-efficacy and performance and was a significant predictor of shooting performance. In addition, advanced shooters were found to have significantly lower average heart rate before shooting and used more self-talk, relaxation, imagery, and automaticity compared to novice and intermediate shooters. HRV was found to be useful in identifying the physiological state of an athlete before competing, and as such, coaches and athletes can adopt practical strategies to improve the pre-performance physiological state as a means to optimize performance.

  • Heart Rate Variability Biofeedback Does Not Substitute for Asthma Steroid
           Controller Medication
    • Authors: Paul M. Lehrer; Charles G. Irvin; Shou-En Lu; Anthony Scardella; Beatrix Roehmheld-Hamm; Milisyaris Aviles-Velez; Jessica Graves; Evgeny G. Vaschillo; Bronya Vaschillo; Flavia Hoyte; Harold Nelson; Frederick S. Wamboldt
      Abstract: Despite previous findings of therapeutic effects for heart rate variability biofeedback (HRVB) on asthma, it is not known whether HRVB can substitute either for controller or rescue medication, or whether it affects airway inflammation. Sixty-eight paid volunteer steroid naïve study participants with mild or moderate asthma were given 3 months of HRVB or a comparison condition consisting of EEG alpha biofeedback with relaxing music and relaxed paced breathing (EEG+), in a two-center trial. All participants received a month of intensive asthma education prior to randomization. Both treatment conditions produced similar significant improvements on the methacholine challenge test (MCT), asthma symptoms, and asthma quality of life (AQOL). MCT effects were of similar size to those of enhanced placebo procedures reported elsewhere, and were 65% of those of a course of a high-potency inhaled steroid budesonide given to a sub-group of participants following biofeedback training. Exhaled nitric oxide decreased significantly only in the HRVB group, 81% of the budesonide effect, but with no significant differences between groups. Participants reported becoming more relaxed during practice of both techniques. Administration of albuterol after biofeedback sessions produced a large improvement in pulmonary function test results, indicating that neither treatment normalized pulmonary function as a potent controller medication would have done. Impulse oscillometry showed increased upper airway (vocal cord) resistance during biofeedback periods in both groups. These data suggest that HRVB should not be considered an alternative to asthma controller medications (e.g., inhaled steroids), although both biofeedback conditions produced some beneficial effects, warranting further research, and suggesting potential complementary effects. Various hypotheses are presented to explain why HRVB effects on asthma appeared smaller in this study than in earlier studies. Clinical Trial Registration NCT02766374.

  • Could White Coat Ocular Hypertension Affect to the Accuracy of the
           Diagnosis of Glaucoma' Relationships Between Anxiety and Intraocular
           Pressure in a Simulated Clinical Setting
    • Authors: Jorge Luis Méndez-Ulrich; Antoni Sanz; Albert Feliu-Soler; María Álvarez; Xavier Borràs
      Abstract: Sixty-one healthy subjects participated in a laboratory study carried out in a simulated clinical setting. Anticipatory anxiety-state was assessed at the arrival and immediately after, with no brief phase of adaptation, measurements of intraocular pressure, heart rate, systolic and diastolic blood pressure were collected. At the end of the procedure, anxiety-trait was also assessed. Results suggest that high levels of both anxiety-state and anxiety-trait significantly predicted a clinically relevant increase of intraocular pressure. Anxiety-state mediated the relationship between anxiety-trait and intraocular pressure, which also was found to be related with heart rate but not related to both systolic and diastolic blood pressure. These results suggest a common mechanism of regulation underlying anxiogenic variability found on both intraocular pressure and heart rate. A reduction in parasympathetic activity appears as a possible mechanism underlying to this phenomenon. This anxiety-enhanced intraocular pressure could be considered a phenomenon analogous to white coat hypertension found in the measurement of blood pressure; therefore, it probably should be taken into account in the clinical context to prevent errors in the diagnosis of glaucoma. Further research on cognitive and emotional regulation of intraocular pressure is needed to best characterize this hypothetical phenomenon.

  • No Effects of Successful Bidirectional SMR Feedback Training on Objective
           and Subjective Sleep in Healthy Subjects
    • Authors: Olaf Binsch; Ellen S. Wilschut; Martijn Arns; Charelle Bottenheft; Pierre J. L. Valk; Eric H. G. J. M. Vermetten
      Abstract: There is a growing interest in the application of psychophysiological signals in more applied settings. Unidirectional sensory motor rhythm-training (SMR) has demonstrated consistent effects on sleep. In this study the main aim was to analyze to what extent participants could gain voluntary control over sleep-related parameters and secondarily to assess possible influences of this training on sleep metrics. Bidirectional training of SMR as well as heart rate variability (HRV) was used to assess the feasibility of training these parameters as possible brain computer interfaces (BCI) signals, and assess effects normally associated with unidirectional SMR training such as the influence on objective and subjective sleep parameters. Participants (n = 26) received between 11 and 21 training sessions during 7 weeks in which they received feedback on their personalized threshold for either SMR or HRV activity, for both up- and down regulation. During a pre- and post-test a sleep log was kept and participants used a wrist actigraph. Participants were asked to take an afternoon nap on the first day at the testing facility. During napping, sleep spindles were assessed as well as self-reported sleep measures of the nap. Although the training demonstrated successful learning to increase and decrease SMR and HRV activity, no effects were found of bidirectional training on sleep spindles, actigraphy, sleep diaries, and self-reported sleep quality. As such it is concluded that bidirectional SMR and HRV training can be safely used as a BCI and participants were able to improve their control over physiological signals with bidirectional training, whereas the application of bidirectional SMR and HRV training did not lead to significant changes of sleep quality in this healthy population.

  • The Impact of Different Visual Feedbacks in User Training on Motor Imagery
           Control in BCI
    • Authors: Dariusz Zapała; Piotr Francuz; Ewelina Zapała; Natalia Kopiś; Piotr Wierzgała; Paweł Augustynowicz; Andrzej Majkowski; Marcin Kołodziej
      Abstract: The challenges of research into brain–computer interfaces (BCI) include significant individual differences in learning pace and in the effective operation of BCI devices. The use of neurofeedback training is a popular method of improving the effectiveness BCI operation. The purpose of the present study was to determine to what extent it is possible to improve the effectiveness of operation of sensorimotor rhythm-based brain–computer interfaces (SMR-BCI) by supplementing user training with elements modifying the characteristics of visual feedback. Four experimental groups had training designed to reinforce BCI control by: visual feedback in the form of dummy faces expressing emotions (Group 1); flashing the principal elements of visual feedback (Group 2) and giving both visual feedbacks in one condition (Group 3). The fourth group participated in training with no modifications (Group 4). Training consisted of a series of trials where the subjects directed a ball into a basket located to the right or left side of the screen. In Group 1 a schematic image a face, placed on the controlled object, showed various emotions, depending on the accuracy of control. In Group 2, the cue and targets were flashed with different frequency (4 Hz) than the remaining elements visible on the monitor. Both modifications were also used simultaneously in Group 3. SMR activity during the task was recorded before and after the training. In Group 3 there was a significant improvement in SMR control, compared to subjects in Group 2 and 4 (control). Differences between subjects in Groups 1, 2 and 4 (control) were insignificant. This means that relatively small changes in the training procedure may significantly impact the effectiveness of BCI control. Analysis of behavioural data acquired from all participants at training showed greater effectiveness in directing the object towards the right side of the screen. Subjects with the greatest improvement in SMR control showed a significantly lower difference in the accuracy of rightward and leftward movement than others.

  • Feeling the Insight: Uncovering Somatic Markers of the “aha”
           Experience
    • Authors: Wangbing Shen; Yu Tong; Yuan Yuan; Huijia Zhan; Chang Liu; Jing Luo; Houde Cai
      Abstract: Whether internal insight can be recognized by experiencing (somatic feeling) remains an unexplored problem. This study investigated the issue by examining potential somatic markers of the “aha” experience occurring at the moment of sudden insight. Participants were required to solve a set of compound remote associates (CRA) problems and were simultaneously monitored via electrodermal and cardiovascular recordings. The “aha”-related psychological components and somatic markers were determined by contrasting insightful solutions with non-insightful solutions. Results showed that the “aha” experience was an amalgam entailing positive affects and approached cognition accompanied by a greater mean skin conductance response (mSCR) amplitude and a marginally accelerated heart rate than the “no-aha” one. These results confirm and extend findings of the multidimensionality of the “aha” feeling and offer the first direct evidence of somatic markers, particularly an electrodermal signature of an “aha” feeling, which suggests a sudden insight could likely be experienced by individuals’ external soma.

  • Using EEG Frontal Asymmetry to Predict IT User’s Perceptions Regarding
           Usefulness, Ease of Use and Playfulness
    • Authors: Christos N. Moridis; Vasileios Terzis; Anastasios A. Economides; Anna Karlovasitou; Vasileios E. Karabatakis
      Abstract: Information systems (IS) community is increasingly interested in employing neuroscience tools and methods in order to develop new theories concerning Human–computer interaction (HCI) and further understand IS acceptance models. The new field of NeuroIS has been introduced to address these issues. NeuroIS researchers have proposed encephalography (EEG), among other neuroscience instruments, as a valuable usability metric, when used effectively in appropriately designed experiments. Moreover, numerous researchers have suggested that EEG frontal asymmetry may serve as an important metric of user experience. Based on the aforementioned evidence, this study aims to integrate frontal asymmetry with Technology acceptance model (TAM). Particularly, we assumed that frontal asymmetry might predict users’ perceptions regarding Usefulness and Ease of Use. Furthermore, we hypothesized that frontal asymmetry might also affect (influence) users’ Perceived Playfulness. Specifically, 82 (43 females and 39 males) undergraduate students were chosen to use a Computer-Based Assessment (while being connected to the EEG) in the context of an introductory informatics course. Results confirmed our hypothesis as well as points of theory about Information technology (IT) acceptance variables. This is one of the first studies to suggest that frontal asymmetry could serve as a valuable tool for examining IT acceptance constructs and better understanding HCI.

      Abstract: The ability to regulate our own physiological arousal when dealing with the emotional expression of our partner is crucial for satisfactory and stable intimate relationships. In previous physiological studies of marital interactions, researchers have found greater levels of psychophysiological arousal for members of the couple in conflictual interactions in comparison with positive interactions. Past researchers have established that intense and prolonged autonomic and neuroendocrine arousal during marital conflict can have negative consequences for mental and physical health. In this study we examined the physiological reactivity, as measured by skin conductance level, heart rate and cortisol levels, from both partners during a couple's interaction task consisting of a structured conversation about positive and negative aspects of their relationship. Participants were thirty-two heterosexual couples (N = 64) in a committed monogamous relationship with a minimum duration of one year. We found higher heart rate and cortisol levels during negative interaction condition when compared with the positive condition. Skin conductance was higher in the positive interaction condition, when compared with the negative interaction condition. In addition, we found a significant negative association between heart rate variability and autonomic arousal evoked by the interaction task. The implications of these findings for the effects of marital strain on health as well as for the design of risk-reducing interventions, namely biofeedback are discussed.

  • Auditory Event-Related Potentials in the Interictal Phase of Migraine
           Indicate Alterations in Automatic Attention
    • Authors: Jeffrey J. Sable; Toni A. Patrick; Patrick L. Woody; Katelyn R. Baker; Stephanie Allen-Winters; Frank Andrasik
      Abstract: Migraine has been characterized by interictal cortical hyperresponsivity. We compared event-related brain potentials (ERPs) to unattended tone pairs in migraineurs (interictal) versus non-headache controls, with particular interest in attention-related activity (i.e., the N1 component). Electroencephalograms were recorded from 11 interictal migraineurs and 14 headache-free controls while they watched a silent video. Pairs of 50-ms tones with 500-ms inter-tone intervals were presented with inter-pair intervals of 1 or 5 s. P1, N1, P2, and N2 components were analyzed. N1 peak amplitudes were larger in migraineurs than in controls, especially after the 5-s inter-pair interval. However, there was no difference between groups in the attenuation of the N1 (i.e., no interaction). P2 peak amplitudes were larger in migraineurs, but only after the first tone in the pair. The three migraineurs without aura had larger N1s than the eight with aura. Our findings are consistent with interictal hyperresponsivity of cortical generators of these ERPs in migraineurs. However, areas that inhibit the responses with stimulus repetition do not seem to be affected.

  • Respiratory Sinus Arrhythmia in Cognitive Behavioral Therapy for
           Posttraumatic Stress Symptoms in Children: Preliminary Treatment and
           Gender Effects
    • Authors: Rebecca S. Lipschutz; Sarah A. O. Gray; Carl F. Weems; Michael S. Scheeringa
      Abstract: Cognitive behavioral therapy (CBT) is an efficacious treatment for posttraumatic stress disorder (PTSD) symptoms, but the effect of CBT on physiological indicators is largely unknown. Respiratory sinus arrhythmia (RSA) is an established parasympathetic marker of self-regulatory capacity and stress responsivity. The present study tested if and how resting RSA and RSA reactivity changed following treatment among a sample of children (n = 48) who experienced at least one traumatic event and presented with PTSD symptoms. RSA reactivity was measured in response to personalized trauma-related scripts. Results indicated that changes in RSA after treatment were dependent on pretreatment resting levels of RSA, with individuals with high and low pretreatment resting RSA levels appearing to converge over time in both resting RSA and RSA reactivity by the 3-month follow up. Specific to RSA reactivity, a sex difference was evident, as following treatment, females showed less RSA withdrawal whereas males showed more RSA withdrawal. PTSD symptoms were significantly reduced after CBT but symptom change was not associated with pretreatment resting RSA levels. Overall, these results suggest that there may be multiple physiological patterns within children with PTSD and the direction of the physiological changes after CBT may depend on initial differences in resting RSA levels.

  • Biofeedback-Aided Relaxation Training Helps Emotional Disturbances in
           Undergraduate Students Before Examination
    • Authors: Zahra Gholami Tahsini; Shahrokh Makvand Hosseini; Farahnaz Kianersi; Shahrzad Rashn; Elahe Majdara
      Abstract: The main aim of the present research was to determine the effectiveness of biofeedback-aided relaxation training (BFRT) for alleviating symptoms of depression, anxiety, and stress for undergraduate students as they prepared for their final examinations. In a randomized controlled trial design, 29 male and female students, with heightened levels of depression, anxiety and stress scores on the Depression, Anxiety, and Stress Scale, were chosen and randomly assigned to BFRT or a no-treatment control condition. Subjects assigned to BFRT received eight sessions of BFRT spaced over 4 weeks, during which they were trained to decrease electromyography (EMG) and respiration rate (RESP) and to increase skin temperature (TEMP). Data were extracted and analyzed by GLM statistical analysis. Students receiving BFRT revealed significant reductions in symptoms when compared to the untreated controls. Those receiving BFRT also showed significant changes for the three targeted psychophysiological modalities (EMG, RESP, and TEMP). It was concluded that BFRT can be useful for reducing symptoms of emotional disturbance in undergraduate students during a particularly stressful period and that this may, in turn, help promote overall psychological health.

  • Thirst at Work Implies More Than Just Inadequate Facilities for Breaks
    • Authors: Maria U. Kottwitz; Romy Schnyder; Martial Berset; Achim Elfering
      Abstract: Early signs of dehydration, such as headaches, are not unusual in the working population. Even slight deficiencies of water intake may have negative effects on both health and performance. However, little is known about work-related fluid intake. We expect the daily experience of interruptions to distract from perceived thirst, resulting in reduced daily fluid intake. This effect may be more pronounced when the workload is generally less predictable due to the assignment of tasks that are beyond the definition of the worker’s professional role (unreasonable tasks). Data were gathered from 29 female service employees across five workdays. Multilevel analyses revealed daily work interruptions to be negatively associated with fluid intake, especially when there were frequent unreasonable task-assignments. Results suggest that interruptions at work might reduce daily fluid intake. However, adequate allocation of tasks by managers can protect employees against insufficient drinking.

  • Skin Conductance Reactivity to Standardized Virtual Reality Combat Scenes
           in Veterans with PTSD
    • Authors: Mascha van ’t Wout; Christopher M. Spofford; William S. Unger; Elizabeth B. Sevin; M. Tracie Shea
      Abstract: Interest in virtual reality (VR) as a clinical tool to augment posttraumatic stress (PTSD) treatment has grown substantially in recent years due to advances in VR technology. Moreover, its potential assisted use in the PTSD diagnostic process has been recognized. In this study we examined physiological responding, skin conductance, to a standardized presentation of non-personalized combat-related VR events (e.g. encountering enemy fire; explosions) as compared to non-combat classroom VR events in 19 Veterans with and 24 Veterans without combat-related PTSD who had been deployed to Iraq and Afghanistan. Veterans watched a total of 12 VR scenarios—six combat-related and six non-combat-related—with each scenario gradually increasing in emotional intensity by adding more VR events in addition to repeating prior VR events. Results show that Veterans with PTSD displayed larger skin conductance reactivity across VR combat events, but not for non-combat VR events, as compared to combat Veterans without PTSD. Nevertheless, Veterans with and without PTSD showed a similar reduction of emotional arousal to repeated presentation of the same VR combat events. Within the PTSD sample, the elevated level of VR combat-related arousal correlated marginally with severity of hyperarousal symptoms. This study confirms that the use of a non-personalized and standardized VR presentation successfully distinguishes Veterans with PTSD from those without on a measure of psychophysiological arousal to combat-related VR stimuli. The assessment of physiological reactivity during the repeated presentation of standardized, trauma-related VR events highlights its use for PTSD assessment as well as treatment.

  • Relevance of the Clinical and Psychophysiological Variables in the
           Dyssynergic Defecation: A Comparative Study in Elderly Subjects
    • Authors: Miguel A. Simón; Ana M. Bueno
      Abstract: The relevance of several clinical and psychophysiological variables in the dyssynergic defecation in elderly subjects was investigated in this study. To accomplish this, 30 elderly subjects (10 without anorectal disorders, 10 with chronic constipation and 10 with dyssynergic defecation) were repeatedly assessed once per week for 4 weeks, with the following measures being collected at each session: EMG-activity (µV) of the external anal sphincter (at rest, during squeezing, and during straining to defecate), stool frequency, difficulty defecation level, pain grade during defecation, and satisfaction level after evacuation. A 3 (group) × 4 (sessions) mixed-measures MANOVA revealed a significant main effect for group (Wilks’s lambda = 0.006; F = 28.45; p < 0.01), but not for sessions (Wilks’s lambda = 0.874; F = 0.94; p > 0.05) or for the group x sessions interaction (Wilks’s lambda = 0.811; F = 1.45; p > 0.05). One-way ANOVA and Scheffé’s posthoc tests were used to isolate the differences between the groups with respect to the seven different measures. These analysis showed significant differences between the groups on all four clinical variables but only for one psychophysiological variable, EMG-activity during straining to defecate. Significant differences were evidenced between all pairs examined for the difficulty defecation level and pain grade. The complete results of these analysis are presented and the conclusions drawn from them are discussed.

  • Reducing Anxiety and Improving Academic Performance Through a Biofeedback
           Relaxation Training Program
    • Authors: Aitor Aritzeta; Goretti Soroa; Nekane Balluerka; Alexander Muela; Arantxa Gorostiaga; Jone Aliri
      Abstract: The aim of this study was to analyze the influence of a biofeedback relaxation training program on anxiety and academic performance. The program consisted of five biofeedback sessions coupled with three training activities focused on deep breathing, guided imagery, and muscle relaxation. The participants were second-year psychology undergraduates from the University of the Basque Country (UPV/EHU, northern Spain). The experimental group comprised 152 students (M age  = 19.6, SD = 0.74; 74% women) and the control group 81 students (M age   = 19.4, SD = 0.92; 71% women). Results showed that after participating in the program, students in the experimental group had lower levels of anxiety and increased academic performance. Furthermore, they scored lower on anxiety and higher on academic performance in comparison with the control subjects. This suggests that the inclusion of biofeedback training programs in educational contexts could be a way of reducing anxiety and improving academic performance. It may also deepen our understanding of the dynamic interplay between psychophysiological, cognitive, and emotional processes.

  • Transitive Versus Intransitive Complex Gesture Representation: A
           Comparison Between Execution, Observation and Imagination by fNIRS
    • Authors: Michela Balconi; Davide Crivelli; Livia Cortesi
      Abstract: The aim of the present study was to examine cortical correlates of motor execution, motor observation and motor imagery of hand complex gestures, in particular by comparing meaningful gestures implying the use of an object (transitive action) or not (intransitive action). Functional near-infrared spectroscopy (fNIRS) was used to verify the presence of partial overlapping between some cortical areas involved in those different tasks. Participants were instructed to observe videos of transitive vs. intransitive gestures and then to execute or imagine them. Gesture execution was associated to greater brain activity (increased oxygenated hemoglobin levels) with respect to observation and imagination in motor areas (premotor cortex, PMC; primary sensorimotor cortex, SM1). In contrast, the posterior parietal cortex (PPC) was more relevantly involved in both execution and observation tasks compared to gesture imagination. Moreover, execution and observation of transitive gestures seemed primarily supported by similar parietal posterior areas when compared with intransitive gestures, which do not imply the presence on a object.

  • Effect of Heart Rate Variability Biofeedback on Sport Performance, a
           Systematic Review
    • Authors: Sergio Jiménez Morgan; José Arturo Molina Mora
      Abstract: Aim is to determine if the training with heart rate variability biofeedback allows to improve performance in athletes of different disciplines. Methods such as database search on Web of Science, SpringerLink, EBSCO Academic Search Complete, SPORTDiscus, Pubmed/Medline, and PROQUEST Academic Research Library, as well as manual reference registration. The eligibility criteria were: (a) published scientific articles; (b) experimental studies, quasi-experimental, or case reports; (c) use of HRV BFB as main treatment; (d) sport performance as dependent variable; (e) studies published until October 2016; (f) studies published in English, Spanish, French or Portuguese. The guidelines of the PRISMA statement were followed. Out of the 451 records found, seven items were included. All studies had a small sample size (range from 1 to 30 participants). In 85.71% of the studies (n = 6) the athletes enhanced psychophysiological variables that allowed them to improve their sport performance thanks to training with heart rate variability biofeedback. Despite the limited amount of experimental studies in the field to date, the findings suggest that heart rate variability biofeedback is an effective, safe, and easy-to-learn and apply method for both athletes and coaches in order to improve sport performance.
