摘要：Purpose: to study reliability of functioning and reserves of system, controlling movements with different coordination structure
of special health group girl students (low health level) in physical education process.
Material: in the research special health group girl students (n=136, age 17-19) participated. They were divided into 2
groups – control and experimental. The program, directed to increase reliability and reserves of system controlling
movements, was realized. It was based on physical exercises of complicated coordination with novelty elements,
which were fulfilled under musical accompaniment. The research continued one academic year.
Results: in girl students with health problems we registered higher differential thresholds, when reproducing local movements
in complicated conditions. They used visual and hearing feedback channels for informing brain’s programming
areas about made mistakes. They were worse teachable in training accurate movements. These girl students have
less expressed compensation reserves under impact of hindering factors and interferences. It can be interpreted
as non-specific crisscross negative response to motor functional system in case of health problems. All these
determine reduction of reserve potentials of motor control system.
Conclusions: The main reserve potentials’ criteria of control over different coordination structure movements are: quickness
of passing to program mechanism of fine movements’ regulation in stable conditions of functioning; power and
effectiveness of compensatory reactions, ensuring interference immunity of system, controlling movements under
interfering factors; reliability of maintaining movements’ qualitative parameters in optimal range under interfering
factors; reduction of sensor interconnections in stable functioning conditions.
