Relation of the competitive activity effectiveness of volleyball players (girls) at the age of 16-18 with the physical development indicators

Abstract

Aim: To determine the impact of different indicators of physical fitness on the competitive activity effectiveness of volleyball players (girls) in the stage of preparation for higher achievements. Material: 22 volleyball players (girls) aged 16–18 participated in the study. Results: significant influence of special physical fitness indicators on the competitive activity effectiveness of volleyball players (girls) at the stage of preparation for higher achievements was established. A high level of correlation was found between the performance of the ball reception after delivery and the speed of the subjects. Significant positive relationships were found between the performance of this techno-tactical action and the speed-power capabilities, the flexibility, and the ability to control the space-time and dynamic parameters of the movements. Intermediate level correlations are found between the effectiveness of volleyball players (girls) atack performance and speed and power capabilities, flexibility, explosive shoulder strength, and mobility in athletes' shoulder joints. The number of effectively performed defensive actions of volleyball players (girls) in official games has reliable mid-level relationships with the speed and speed-power capabilities, ability to kinesthetic differentiation, and speed endurance. A high level of correlation is found between the effectiveness of body blocks from the opponent’s hits and the rate of standing vertical jump. Reliable low- and medium-level relationships were found between this techno-tactical performance of volleyball players (girls) and indicators of speed, agility, and endurance. A close relationship is found between the delivery quality and the ability to evaluate and differentiate the space-time and dynamic motion parameters. Conclusions: The level of special physical fitness significantly influences the effectiveness of technical and tactical actions of volleyball players (girls) aged 16-18 in the conditions of competitive activity. High efficiency of competitive activity of volleyball players (girls) at the stage of preparation for higher achievements is impossible without the appropriate level of development of speed, agility, speed-power abilities, special endurance. Selection of special exercises and dosage of training load taking into account the individual characteristics of volleyball players (girls) will positively influence the competitive activity results and will allow to avoid health problems.
