Comparison of the effectiveness of correcting the sensory perception of skilled tennis players through auditory deprivation and improving the function of the visual analyzer

Abstract

Introduction. In the context of the need to search for new means and methods of improving the training process of adolescent tennis players, which are practically exhausted in terms of improving physical fitness and technical skills, a significant pedagogical task arises – to identify the possibility of effective influence on the sensory-perceptual processes of athletes as a factor of sensorimotor coordination of motor actions and cognitive functions. The purpose of the article is to determine the effectiveness and expediency of using two approaches to correcting and improving the sensory perception of tennis players aged 17-18 years – the exclusion of an acoustic stimulus during the game or the inclusion of additional means of influencing the visual analyzer. Methods and materials. The study involved tennis players aged 17-18 years with the first sports category, among 28 athletes who were divided into two groups: the first experimental group (EG-1) included 14 young athletes who practiced for 6 weeks (4 classes per week) according to a program based on hearing deprivation in the classroom. The second group, EG-2, was engaged in using special visual exercises as an out-of-training tool. Methods: literature analysis, pedagogical experiment, instrumental methods (Babolat Pure Drive Play, Eye-Tracking technology), questionnaires, methods of mathematical data processing (descriptive statistics, Student's t-test). Results. During the experiment, it was found that a group of tennis players who were engaged in a training program with the exception of hearing (EG-1) showed the best results in all the studied indicators. In particular, statistically significant differences were obtained between the groups in terms of fixation time at the target object, which improved in EG-1 by 33.7-37.8% (t=4.19-4.28, p<0.01), in EG-2 – by 10.7-11.9% (t=3.26-3.38, p<0.01), intergroup differences were established at t=4.65-4.79, p<0.01. Conclusion. The results obtained indicate that the indirect effect on the sensory perception of qualified tennis players through local sensory deprivation of one of the analyzers – acoustic, as a way to create complicated and variable conditions in the mode of a traditional training session, is more effective, expedient and easy to use, compared with the introduction for the same purposes, out-of-training tools, including direct effect on the visual analyzer using special exercises for the eyes.
