Heart rate regulation features in young boxers at the age of 12-15 under application of restorative techniques

To reveal features of heart rate regulation in young boxers at the age of 12-15 and to provide physiological foundation of restorative techniques applied at the direct pre-contest preparation stage. We formed two main groups: 16 boxers, aged 12.30 ± 0.42, boxing experience - 2.50 ± 0.25 years, and 16 boxers, aged 14.05 ± 0.50, boxing experience - 3.25 ± 0.30 years, and also two control groups with corresponding number and age of participants. Using diagnostic complex “Omega-S” we performed studies of cardiovascular state parameters and heart rate slow wave variability parameters before, immediately after and in 24 hours after fighting practice training, as well as after restorative techniques had been integrated during four week micro-cycles. The mentioned techniques were aimed at enhancement of functional state indicators and at improvement of sport performance of the young boxers according the suggested original program. We revealed adaptive reactions in cardiovascular state of 12-13-year old boxers in terms of regulation process adequacy and heart rate autonomic indicator in 40 % of the survey sample. The same was revealed in 14-15-year old boxers in terms of autonomic balance and regulation process adequacy in 25 %. Maladaptive reactions in young boxers' state were manifested in terms of heart rate variability in 65 % of the survey sample. Cardiovascular functional state in boxers aged 12-15 at the direct pre-contest preparation stage is specified by presence of adaptive and maladaptive reactions of the body. At restorative technique being applied young boxers show enhanced adaptive and compensatory abilities of suprasegmentary mechanisms of heart rate regulation.
