Objective of the study was to study the structure of the relationships between psychophysiological indicators, parameters of heart rate variability, which determine the success of technical and tactical activities of boxers in competitive activities.
Methods and structure of the study. The scientific work involved boxers aged 18-20: 15 men and 10 women. The hardware and software complex «Varicard 2.52» recorded statistical and spectral characteristics of heart rate variability to assess the functional state. The functional state of the central nervous system was determined using the psychophysiological testing device UPFT-1/30 «Psychophysiologist».
Results and conclusions. It was found that the percentage of successful punches in female boxers has a close feedback relationship with the stability of the response in a simple visual-motor reaction, the values ​​of tremometry and the stress index of heart rate variability. In male boxers, the percentage of successfully executed punches is associated with the indicators of a simple visual-motor reaction, the stability of the response and the values ​​of VLF waves, which determine the stress load on the athlete's body.

Keywords: heart rate variability, simple visual-motor reaction, tremometry, success of technical and tactical actions, boxers.
