چکیده
Growing ; evidence suggests that Heart Rate Variability (HRV) biofeedback (BFB) may improve sport performance by helping athletes cope with the stress of competition. This study sought to identify whether HRV BFB procedure impacted psychological, physiological, and sport performance of a collegiate golfer. This individual was randomly selected to participate in 10 weeks of HRV BFB training according to the protocol developed by Leher, Vaschillo, and Vaschillo (2000). During the first, fourth, seventh, and tenth weeks of the study, the golfer and principal investigator met at a virtual reality golf center to practice skills for breathing at resonance frequency during golf performance. Results of the golf performance and HR were recorded during nine holes of virtual reality golf before and after 10 weeks of HRV BFB training. Self-report questionnaires were administered also before and after HRV BFB training to measure symptoms of anxiety, stress, and sensation seeking. Physiological measures, including HRV and respiration rate, were recorded in the lab during the first, fourth, seventh, and tenth weeks of the study. Golf performance and HRV were recorded during nine holes of virtual reality golf. Reduction in symptoms of anxiety, stress, and sensation seeking and increases in total HRV, low-frequency HRV, and amplitude of oscillation at .1 Hz and sport performance improving were observed. This effect became stronger across 10 weeks of HRV BFB training, suggesting that HRV BFB may improve sport performance by helping athletes to cope with sport stress. A larger-scale study was conducted and is in the process of analysis to confirm these findings.

Heart rate variability (HRV) biofeedback (BFB) is a relatively new approach for helping athletes to regulate competitive stress. To investigate this phenomenon further, a qualitative case study examined the impact of HRV BFB on the mood, physiology, and sport performance of a 14-year-old golfer. The golfer met once per week at a university lab for 10 consecutive sessions of HRV BFB training tha...

Psychophysiological studies and MRI neuro-imaging findings provide evidence that heart rate variability (HRV) which is in control of our emotions affects our brain cognitive centers. It has been shown that coherent heart-brain interaction can change the pattern of the afferent cardiac input that is sent to the brain. For this purpose, the Institute of HeartMath (IHM) has proposed a kind of biof...
