IDENTIFICATION OF THE RELATIONSHIP BETWEEN PSYCHOPHYSIOLOGICAL INDICATORS AND PHYSICAL PERFORMANCE OF VOLLEYBALL PLAYERS OF DIFFERENT AGE GROUPS

The purpose of the research is to determine the relationship between physical performance and psychophysiological indicators of volleyball players of various qualifications.

Methods and organization of research. Volleyball students (17-25 years old) and volleyball schoolchildren (13-14 years old) in the amount of 20 people, divided into experimental and control groups, were studied. The experiment included the diagnosis of psychophysiological indicators and physical performance using the bicycle ergometer «Kettler ergometer E3», the heart rate monitor Polar RS 800c XW «Polar Elestiooy», the hardware and software complex «Microlux MARG 10-01», the hardware and software complex «AC-9K Activationometer». 

The research results and their discussion. The absence of connections of psychophysiological indicators among themselves (eye, motor memory, coordination of movements, attention switching) was revealed in volleyball schoolchildren. In volleyball students, the relationship was manifested between the indicators of motor memory, coordination of movements and attention switching. Compared with volleyball schoolchildren, volleyball students have more connections between groups of indicators of physical performance and psychophysiological indicators. 

Conclusion. The data obtained indicate that the central indicators are VO2max and PWC170 in terms of physical performance. The results of the study also indicate that there is a relationship between indicators of physical performance and psychophysiological indicators. However, the values of the correlation coefficients are not statistically significant due to a small sample and a relatively large age range of volleyball students, which requires further study of this issue.
