The success of an operator’s activities depends on the safety of the SF. To study the impact of the SF factor (support unloading), a ground-based “Dry” Immersion (DI) model is used. The study was conducted for 7 days under DI conditions. During the visual-motor task, 10 participants moved the cursor from the center of the screen to randomly appearing peripheral targets using a joystick. The DI effect on cursor movement parameters in four directions was evaluated. There were differences in time and accuracy depending on the hand movement direction in control studies that persisted during and after DI exposure. In the early days of DI, most estimated cursor movement parameters deteriorated, regardless of the direction. By the end of the immersion, they had recovered. The degree of DI influence on cursor movement differed depending on the direction of hand movement, and was most pronounced at the beginning of DI. There was minimal impact of DI on movement from left to right.</p></abstract><trans-abstract xml:lang="ru"><p>Вопросы, связанные с управлением движением руки в космическом полете (КП), являются крайне важными. От успешности выполнения операторской деятельности зависит безопасность КП. Для исследования влияния фактора КП (опорной разгрузки) используют наземную модель “сухой” иммерсии (СИ). Исследование проведено в условиях 7-суточной СИ. Во время выполнения зрительно-двигательной задачи перемещения курсора с помощью джойстика из центра экрана на одну из периферических мишеней, появляющихся в случайном порядке, у 10 испытуемых проведена оценка влияния СИ на параметры движения курсора в четырех направлениях. Показаны различия временных и точностных параметров выполнения задачи в зависимости от направления движения руки в контрольных исследованиях, которые сохраняются во время и после воздействия СИ. В первые дни СИ большинство оцениваемых параметров движения курсора ухудшались вне зависимости от направления, к концу иммерсии они восстанавливались. Степень воздействия СИ на параметры движения курсора отличалась в зависимости от направления движения руки и была максимально выражена в первые дни СИ. Минимальное воздействие СИ оказала на движение слева направо.</p></trans-abstract><kwd-group xml:lang="en"><kwd>“dry” immersion</kwd><kwd>support unloading</kwd><kwd>visual-motor task</kwd><kwd>joystick</kwd><kwd>arm movement direction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>“сухая” иммерсия</kwd><kwd>опорная разгрузка</kwd><kwd>зрительно-двигательная задача</kwd><kwd>джойстик</kwd><kwd>направление движения руки</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Badakva A.M., Miller N.V., Zobova L.N., Roshchin V.Yu.
