The features of the formation and modification of synergetic modules depending on the motor task are considered. An attempt is made to combine some computational aspects applied according of various concepts of synergetic control. The tools for identifying and analyzing synergy parameters included regression analysis and data factorization methods. It has been established that differing in biomechanical structure balance exercises can be realized using common patterns of kinematic synergies spatial organization, however, at the muscular level, the existence of common spatial activation profiles is not obvious. The presence of several different time patterns of synergy activation in the structure of each balance exercise has been revealed, which may be associated with various motor control strategies in the central nervous system. The structure of kinematic synergies may be influenced by artificial degrees of freedom restriction, unrelated to central control processes. It is shown that the inclusion of the concept of “variables’ area” in the motor control modular organization theory contributes to the convergence of existing motor control concepts based on synergy principle.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181325222752">В работе представлена структура двигательных синергий на мышечном и кинематическом уровнях их исследования при выполнении различных спортивных равновесий. Рассматриваются особенности формирования и модификации синергетических модулей в зависимости от реализуемой двигательной задачи. Предпринята попытка объединения некоторых вычислительных аспектов, применяемых в рамках различных концепций синергетического контроля. Инструментарий для выявления и анализа параметров синергий включал регрессионный анализ и методы факторизации данных. Установлено, что разные по биомеханической структуре равновесия могут быть реализованы с применением общих паттернов пространственной организации кинематических синергий, однако на мышечном уровне существование общих пространственных профилей активации не очевидно. Выявлено наличие нескольких разных временных паттернов активации синергий в структуре каждого рассматриваемого равновесия, что может быть связано с применением в ЦНС различных стратегий двигательного контроля. На структуру кинематических синергий может оказывать влияние искусственное ограничение степеней свободы, не связанное с центральными процессами управления. Показано, что включение понятия “пространство переменных” в положения о модульной организации способствует сближению существующих концепций двигательного контроля, основанных на синергии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>motor synergies</kwd><kwd>static balance</kwd><kwd>data factorization</kwd><kwd>motor control</kwd><kwd>gymnastics</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>двигательные синергии</kwd><kwd>статическое равновесие</kwd><kwd>факторизация данных</kwd><kwd>двигательный контроль</kwd><kwd>художественная гимнастика</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность сотрудникам Научно-исследовательского института проблем спорта и оздоровительной физической культуры Великолукской государственной академии физической культуры и спорта А.М.
