Abstract
Introduction. The study of the individual typological features at different stages of long-term training and during the annual cycle is a necessary component of control in basketball, as indicated by many domestic and foreign experts. The purpose of the study is improving the effectiveness of control in basketball by identifying the relationship between psychophysiological indicators and proprioceptive sensitivity of basketball players. Methodology and organization of research. 24 basketball players took part in the study. The age of the athletes was 20±1.45 years, the experience of sports-5±0.36 years. The sensory component of the psychophysiological state was determined by using the computer system "Diagnostic1". We also determined the strength of the hands and proprioceptive sensitivity of the hands by applying hand dynamometry. The research was conducted at the Shenzhen University, Shenzhen, China. Research results and discussion. A correlation analysis of psychophysiological indicators and parameters of strength, proprioceptive sensitivity of the hands, and the ability to reproduce the specified muscular efforts of basketball players was performed. The results of pair correlation allowed us to reveal average and strong connections between the studied parameters. The correlation coefficients ranged from r = 0.346 (p <0.05) to r = -0.848 (p <0.01). Conclusions. The highest value of the correlation coefficient found between the time of latent period of simple sensorimotor reaction and play-50% power of the left hand with the visual analyzer (r = 0,711, p <0.01), play 50% of the strength of the right hand without participation of the visual analyzer (r = 0,707, p <0.01), play 50% of the strength of the left hand without involvement of the visual analyzer (r = 0,710, p <0.01). The indicator of total time when performing a test aimed at determining the level of functional mobility of nerve processes is strongly correlated with the values of reproducing 50% of the strength of the right hand with the visual and without the participation of the visual analyzer – r = 0.732 and r = 0.733 (p <0.01), respectively. The minimum exposure time of the signal is closely correlated with the strength of the right hand (r = 0.848, p <0.01).
Keywords: control, basketball, psychophysiological functions, correlation coefficient, strength of nervous processes.
