摘要：To determine the influence of indicators of psychophysiological functions and typological features of the nervous system on the effectiveness of competitive activity of volleyball players (girls) aged 16 to 18. The study involved 18 volleyball players (girls) aged 16 to 18. Significant influence of indicators of sensorimotor,proprioceptive,perceptual and intellectual functions on the efficiency of volleyball players’ (girls’) competitive activity at the stage of preparation for higher achievements was established. The average correlation was found between the efficiency of ball reception after submission and the speed of information processing,the ability to distribute attention,the assessment of muscular efforts,strength and mobility of nervous processes. Reliable relationships were found between the effectiveness of volleyball players (girls’) defensive actions and the speed of switching attention,the speed of motor responses. The performance of volleyball players (girls) has significant positive relationships with the speed and quality of operational thinking,the ability to differentiate movement parameters and response choices,and the mobility of the nervous system. The average level of interrelationship is found between the effectiveness of opponent’s blocking spikes and the volleyball players’ (girls’) mental processes,attention switching speed,muscular efforts differentiation,complex reaction of choice. Reliable correlations were found between the quality of ball delivery and the speed of thinking,the ability to kinesthetic sensations,the balance of nervous processes. Typological features of the volleyball players’ nervous system determine the nature of their behaviour in the process of competitive activity,reflected in the characteristics of their game situation assessment and in the decision-making nature. Taking into account the temperament type will allow the trainer to take an individual approach to each athlete and make timely adjustments to the training process.
