Объектом исследования является учебнотренировочный процесс подготовки волейболистов сборной команды ДГТУ. Разработаны алгоритм количественной оценки возможности травмирования и обоснование мероприятий по упреждению травм в ходе подготовки и проведения соревнований волейболистов. Проанализированы статистические данные о типовых травмах волейболистов и о вероятных условиях их возникновения; выбраны и изучены причины, признаки и показатели типовых травм волейболистов сборной команды ДГТУ; получены численные значения индивидуального риска травмирования волейболистов сборной команды ДГТУ; разработаны технические предложения по индивидуальным средствам защиты волейболистов ДГТУ. The object of the research is training process of volleyball players of DSTU combined team. The article provides the algorithm of quantitative assessment of injuries and the justification of measures for injuries prevention during training and competitions of volleyball players. It analyzes statistical data on typical volleyball players’ injuries and probable conditions of their occurrence. The authors have selected and studied the causes, signs and indicators of typical injuries of DSTU volleyball combined team. They have obtained the numerical values of individual risk of volleyball players’ injury of DSTU combined team; have developed technical proposals for personal protective equipment for DSTU volleyball players.
