摘要

的目标。本文旨在揭示听力障碍排球运动员的中枢神经系统特征和半球间不对称性。材料和方法。研究对象为14名有不同运动经历的听力障碍程度的运动员,年龄20 ~ 35岁,平均年龄29.20±1.3岁。从反应时间、反应稳定性、神经系统功能等方面对单纯视觉反应进行了研究。为了确定手的不对称性,使用了M. Annette问卷和运动测试(测力、手指缠绕测试、鼓掌测试),计算了右手的系数。在检测视觉不对称时,采用罗森巴赫检验和望远镜检验。并计算了右眼的系数。结果。研究发现,三分之一的被调查运动员在视觉和手的球体上都有对称的标志分布。没有发现对称分布与体育头衔之间的可靠依赖关系。听力障碍排球运动员的反应时间明显缩短。反应稳定性和功能能力水平均在正常范围内,且对运动等级和运动类别有显著的依赖性。结论。结果表明,听力障碍排球运动员形成了一种特殊的左右半球相互作用类型,其特征是左右半球之间的分布更为均匀,导致手和视觉不对称值较低。

PSYCHOPHYSIOLOGICAL FEATURES OF VOLLEYBALL PLAYERS WITH HEARING IMPAIRMENT
Aim. The paper aims to reveal the features of the central nervous system and interhemispheric asymmetry in volleyball players with hearing impairment. Materials and methods. The study involved 14 athletes of various sports experience with varying degrees of hearing impairment aged from 20 to 35 years (average age 29.20 ± 1.3 years). Simple visual reaction was studied in terms of the reaction time, reaction stability, and functional capabilities of the nervous system. To establish the manual asymmetry, the M. Annette questionnaire and motor tests (dynamometry, tests for intertwined fingers, the applause test) were used, the coefficient of the right hand was calculated. When detecting visual asymmetry, the Rosenbach test and the telescope test were used. The coefficient of the right eye was also calculated. Results. It was established that a third of the examined athletes had a symmetric distribution of signs in both the visual and manual spheres. The reliable dependence between symmetric distribution and sports titles was not found. The reaction time in volleyball players with hearing impairment was reduced. The reaction stability and the level of functional capabilities were within the normal range and had a significant dependence on the sports rank and category. Conclusion. It was revealed that volleyball players with hearing impairment formed a special type of interhemispheric interaction characterized by a more uniform distribution between the right and left hemispheres, which resulted in low values of manual and visual asymmetry.
