One of the key informative health indicators is the nutritional status, which quickly responds to changes in operating conditions and shows how military personnel adapts to environmental factors. Body composition and morphofunctional status are an integral part of nutritional status. The effect of high physical stress on the body composition and morphofunctional status of military personnel remains relevant.</p> <p><bold>AIM</bold><bold>:</bold> To study the effect of a 21-day cycle of high physical stress on the morphofunctional status and body composition of military personnel to assess the efficiency of this approach in quickly improving their physical condition.</p> <p><bold>METHODS</bold><bold>:</bold> A total of 15 male military personnel aged 22 to 27 years were examined using the anthropometric and bioelectrical impedance analysis.</p> <p><bold>RESULTS</bold><bold>:</bold> The study revealed a significant increase in the muscle body composition (skeletal muscle and active cell mass) and the estimated shoulder muscle circumference. However, fat composition (fat mass, body fat percentage, and visceral fat area) remained unchanged. This is consistent with the anthropometric analysis.</p> <p><bold>CONCLUSION</bold><bold>:</bold> The study showed a positive effect of 21-day proportioned high physical stress on the nutritional status and body composition of military personnel.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Современные условия военно-профессиональной деятельности, в том числе в зоне ведения специальной военной операции, связаны с интенсивными физическими нагрузками, что требует высокого уровня здоровья, которое в значительной степени зависит от полноценного питания. Один из основных информативных показателей здоровья — статус питания, который оперативно реагирует на изменение условий деятельности, а также отражает степень адаптации военнослужащих к факторам среды обитания. Состав тела и морфофункциональное состояние организма являются неотъемлемой частью статуса питания. Актуальным остаётся влияние интенсивных физических нагрузок на компонентный состав тела и морфофункциональное состояние организма военнослужащих.</p> <p><bold>Цель исследования.</bold> Изучить влияние 21-дневного цикла интенсивных физических нагрузок на морфофункциональное состояние и компонентный состав тела военнослужащих для оценки эффективности данного подхода в оперативном улучшении их физического состояния.</p> <p><bold>Методы.</bold> Были обследованы военнослужащие мужского пола в возрасте от 22 до 27 лет в количестве 15 человек. Использовались следующие методы: антропометрия и биоимпедансометрия.</p> <p><bold>Результаты.</bold> В результате исследования выявлен статистически значимый рост мышечной компоненты состава тела (скелетно-мышечная и активная клеточная масса) и расчётного показателя окружности мышц плеча. При этом показатели жировой компоненты (жировая масса, процент содержания жира в организме и площадь висцерального жира) оставались без изменений. Это согласуется с данными антропометрического исследования.</p> <p><bold>Заключение.</bold> Проведённое исследование выявило положительное влияние 21-дневной дозированной интенсивной физической нагрузки на статус питания и компонентный состав тела военнослужащих.</p></trans-abstract><kwd-group xml:lang="en"><kwd>anthropometric analysis</kwd><kwd>bioelectric impedance analysis</kwd><kwd>nutritional status</kwd><kwd>body composition</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>антропометрия</kwd><kwd>биоимпедансометрия</kwd><kwd>статус питания</kwd><kwd>состав тела</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source></award-group><funding-statement xml:lang="en">The research was funded under the Priority 2030 program.</funding-statement><funding-statement xml:lang="ru">Финансирование исследования осуществлялось в рамках программы «Приоритет-2030».</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Islamov VA, Dalskii DD, Salnikov VA.
