Abstract
Introduction. It has been established that cerebral palsy (CP) arises from brain damage, leading to persistent non-progressive motor disorders, including paralysis, paresis, hyperkinesia, ataxia, and others. To correct motor impairments in individuals with CP, systematic training in adaptive physical culture is recommended. During such training, there is an improvement in motor function, mood, stress reduction, social integration, and other positive changes. Functional status improvements also occur in those who engage in adaptive physical culture, although they are currently described incompletely. Attention is drawn to the lack of information on heart rate variability (HRV) in individuals with CP during adaptive physical culture training. The purpose of the study is to analyze heart rate variability indicators in individuals with cerebral palsy who engage in adaptive physical culture. Research methods. The study was conducted on the basis of the Prydniprovsk State Academy of Physical Culture and Sports. The experimental group included 24 male persons with cerebral palsy, aged 20 to 25, who attended football, athletics and weightlifting sports sections. The training experience of persons with cerebral palsy in sports sections was at least 1 year. The control group consisted of 20 student-athletes aged 20 to 25 years who trained in similar sports. HRV was registered using the automated hardware and software complex "Cardio+" (Ukraine, Nizhyn) in the educational and scientific laboratory of the Prydniprovsk State Academy of Physical Culture and Sports. HRV was studied according to the method of R.M. Baievskyi. Research results. In the control group of student athletes at rest, higher values of Mo and ΔX were noted compared to norms for healthy untrained individuals, along with lower indicators of AMo, IN, HRV, VPR, and PAPR, reflecting the development of adaptive mechanisms in the form of increased tone of the parasympathetic branch of regulation, decreased tension of central-type regulation, and increased activity of the autonomous circuit of heart rate regulation. Similar changes in HRV indicators were observed in individuals with CP who had been engaged in adaptive physical culture for a long time. At the same time, the degree of central influences on heart rate, as indicated by IN, was significantly higher in individuals with CP than in student athletes, which is probably due to the greater complexity of adaptive reactions in CP. Conclusions. The registered values of HRV indicators in individuals with cerebral palsy indicate adaptation of their cardiovascular system to physical exertion and a positive influence of adaptive physical culture on the autonomic regulation of bodily functions
