STUDY OF INDICATORS OF HEART RATE VARIABILITY OF ACROBATS AT THE STAGES OF LONG-TERM TRAINING IN THE ASPECT OF SEXUAL DIMORPHISM

Aim: Study and comparative characteristics based on the data of heart rate variability (HRV) analysis of athletes specializing in pair-group acrobatics, taking into account age, features of sexual dimorphism at various stages of multi-year training Materials and Methods: Acrobats of both sexes, of different sports qualifications, of the following stages of long-term training took part in the study: 1) group of training 9-11 years old: girls (n=38), boys (n=38); 2) sports improvement groups aged 12-15: girls (n=36), boys (n=36); 3) groups of higher sports skills aged 16-23: girls (n=32), boys (n=32). Results: A gender comparison was made between groups of acrobats aged 9-11 years, but no statistically significant differences between girls and boys were found (р>0.05). Comparative characteristics of boys 12-15 and 16-20 years old shows a statistical difference (p 0.5). Conclusions: In each of the age and gender groups, at different stages of multi-year improvement, acrobats with a different type of regulation – central or autonomous – were identified. The correlation analysis of the 12-15-year-old age group allowed us to obtain the following results: a high and medium degree of correlation between LF and TP indicators in both girls and boys (r=0.82 and r=0.66, respectively). A relationship between VLF and TP indicators was also revealed, in girls r=0.78 and in boys r=0.72.
