Physiological criteria for successful competitive activity of a professional boxer

Nowadays there is need to find informative indicators that could be viewed as predictors of the athlete's successful competitive activity. As such, for a professional boxer are offered aerobic and anaerobic indices that are calculated based on ECG parameters. The primary analysis of bioelectric signals on the software Omegawave Team + V4. 5 (Omegawave, Finland) was performed to calculate the indexes. We used the am-plitude-frequency analysis. The bioelectrical activity of the heart was recorded using a portable, wireless, single-channel amplifier, located in a special chest strap. The aerobic index is a ratio of R-wave amplitude to the sum of R- and S-wave amplitude. The anaerobic index is the ratio parameters of the maximum and minimum amplitude of the T-wave to the amount of R and S. It was established that the changes of aerobic and anaerobic indexes in the preparation of a professional boxer for fighting have different directions. The growth of aerobic index and the decrease of anaerobic index during the preparatory period for the competition day are optimal changes that have a connection with the successful performance. Aerobic and anaerobic indices allow to predict the professional boxer's realization of functional abilities and to determine the effectiveness of athlete's management training.
