   <abstract xml:lang="ru">
    <p>Актуальность. Связь между соревновательной тревожностью и показателями вариабельности сердечного ритма (ВСР) неоднозначна, особенно если спортсменов оценивают за пределами непосредственно предсоревновательного периода.&#13;
Цель. Изучить взаимосвязи соревновательной тревожности с автономной, дыхательной и сенсомоторной регуляцией у спортсменов единоборств вне соревновательной ситуации.&#13;
Методы. Обследованы 40 спортсменов (16–27 лет), занимающихся каратэ, киокушинкай, ушу и тхэквондо. Тревожность оценивали по CSAI-2. В покое регистрировали фотоплетизмограмму с расчетом линейных и нелинейных показателей ВСР, а также параметры&#13;
дыхания. Сенсомоторные функции оценивали по комплексу визуально-моторных тестов. Данные были z-стандартизированы, применялись корреляционный анализ, кластеризация k-means и PERMANOVA.&#13;
Результаты. Значимых корреляций между шкалами тревожности и автономными или сенсомоторными показателями не выявлено. Кластерный анализ выделил две группы: с более высокой тревожностью и сниженной уверенностью и с адаптивным психологическим профилем. При отсутствии значимых однофакторных различий отмечена тенденция к снижению вагусных индексов (RMSSD, pNN50), амплитуды абдоминального дыхания и автономной сложности, а также к большей вариабельности сложной реакции в группе с более высокой тревожностью. Многомерный анализ показал тенденцию к различию&#13;
интегральных психофизиологических профилей (p=0,08).&#13;
Заключение. Вне соревновательного контекста тревожность не связана с отдельными физиологическими показателями, однако проявляется на уровне интегративных многомерных конфигураций. Результаты подчеркивают значимость системного подхода к анализу психофизиологических состояний спортсменов.</p>

    <p>Relevance. The association between competitive anxiety and heart rate variability (HRV) remains inconsistent, especially when athletes are evaluated outside the immediate pre-competition period.&#13;
Objective. To examine relationships between competitive anxiety and autonomic, respiratory, and sensorimotor regulation in martial arts athletes during a non-competitive training phase.&#13;
Methods. Forty athletes (aged 16–27) who practice karate, kyokushin, wushu, or taekwondo were assessed during regular training sessions. Competitive anxiety was measured using the Competitive State Anxiety Inventory-2 (CSAI-2). Resting photoplethysmography (5-minutes, seated) was recorded to calculate linear and nonlinear heart rate variability (HRV) indices, as well as respiratory parameters. Sensorimotor performance was assessed using a battery of visual-motor tasks. All variables were standardized using z-scores. Correlation analysis, k-means clustering, and PERMANOVA were used for analysis.&#13;
Results. No significant correlations were found between anxiety subscales and autonomic or sensorimotor indicators. Cluster analysis identified two psychological profiles: a group with higher anxiety and lower confidence, and a more adaptive group with lower anxiety and higher confidence. Although univariate differences did not reach statistical significance, the group with higher anxiety showed consistent trends towards lower vagal activity (RMSSD, pNN50), reduced abdominal respiratory amplitude, reduced autonomic complexity, and increased variability in choice reaction time. Multivariate analysis suggested a trend towards differentiation of integrated&#13;
psychophysiological profiles (p=0.08).&#13;
Conclusion. In non-competitive conditions, anxiety was not related to individual physiological markers, but rather reflected in integrated, multivariate configurations. These findings emphasize the significance of multidimensional approaches in sports psychophysiology.</p>
