conclusion the results of the study suggest that biofeedback training may help to train stressed athletes to acquire a control over their psychophysiological processes, thus helping an athlete to perform maximally. results two way repeated measure anova was used to simultaneously compare within and between group differences. response time, concentration, heart rate variability, respiration rate...
OBJECTIVE Low heart rate variability (HRV) has been confirmed in heroin users, but the effects of heart-rate-variability-biofeedback in heroin users remain unknown. This study examined (1) correlations between depression and HRV indices; (2) group differences in HRV indices among a heroin-user group, a group with major depressive disorder but no heroin use, and healthy controls; and (3) the eff...
Heart rate variability biofeedback is known to have multiple effects on the cardiovascular system, the respiratory system, and emotional reactivity. This paper reviews the origins of work on heart rate variability biofeedback, and mechanisms for its various effects, including direct effects on the baroreflex system and gas exchange efficiency, as well as indirect effects on emotional reactivity...
Heart rate variability biofeedback is a burgeoning clinical intervention for a variety of disorders. This paper describes a handheld heart rate variability biofeedback device called the StressEraser. The role of home training devices, the device algorithm and biofeedback method, and current research findings are highlighted. Additional attention is paid to the importance of user preferences and...
OBJECTIVE We evaluated heart rate variability biofeedback as a method for increasing vagal baroreflex gain and improving pulmonary function among 54 healthy adults. METHODS We compared 10 sessions of biofeedback training with an uninstructed control. Cognitive and physiological effects were measured in four of the sessions. RESULTS We found acute increases in low-frequency and total spectru...
Paper is destined for use in medicine, psychology and psychophysiology, in man’s selfdevelopment training, breathing technique’s training, in the field of stress resistance, health promotion, strengthening of the capacity for work; and it relates to the apparatus and methods for detection of the heart rate variability and it’s use in providing biofeedback during training sessions of organism’s ...
Heart rate variability for the treatment of major depression is a novel, alternative approach that can offer symptom reduction with minimal-to-no noxious side effects. The following material will illustrate some of the work being conducted at our laboratory to demonstrate the efficacy of heart rate variability. Namely, results will be presented regarding our published work on an initial open-la...
This study describes the use of a biofeedback method for the noninvasive study of baroreflex mechanisms. Five previously untrained healthy male participants learned to control oscillations in heart rate using biofeedback training to modify their heart rate variability at specific frequencies. They were instructed to match computer-generated sinusoidal oscillations with oscillations in heart rat...
The objective of this study was to define specific breathing patterns and examine the effects these patterns have on indicators of heart rate variability. Perceived accounts of ease and comfort in relation to the patterned breathing applications also were assessed. A breathing pattern is the within-cycle respiratory timing or the ratio between the inspiration and expiration of breath, including...
