В игровых видах спорта одним из ключевых когнитивных процессов является внимание. Соревновательная результативность в хоккее напрямую зависит от быстроты принятия решения и эффективности обработки информации в условиях дефицита времени. В публикационном поле отсутствуют пороговые значения показателей внимания, позволяющие дифференцировать игроков с разным уровнем результативности.</p></sec><sec><title>Цель</title><p>Цель. Оценка прогностического потенциала показателей концентрации и устойчивости внимания в отношении спортивных результатов нападающих студенческой хоккейной команды.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В кросс-секционное исследование были включены 50 хоккеистов студенческой команды Уральского государственного университета физической культуры (игровое амплуа — нападающие) в возрасте 21,9 ± 1,9 года. Устойчивость и концентрацию внимания (числовой и балльный показатели) определяли путем психофизиологического тестирования на аппаратно-программном комплексе «НС-ПсихоТест». Результативность оценивали по интегральному показателю технико-тактических действий (ТТД), рассчитанному тренерским штабом по итогам официальных матчей. На основе распределения ТТД игроки разделены на три группы: группа 1 (ниже 25-го процентиля, низкая результативность, n = 16), группа 2 (в диапазоне 25–75 процентилей, средняя результативность, n = 18) и группа 3 (выше 75-го процентиля, высокая результативность, n = 16). Сравнение групп выполнено с использованием непараметрических критериев (Краскела — Уоллиса, Манна — Уитни), размер эффекта оценен по d Коэна. Прогностическая способность показателей концентрации внимания определена с помощью ROC-анализа с расчетом площади под кривой (AUC), чувствительности, специфичности, положительной прогностической ценности (PPV) и отрицательной прогностической ценности (NPV).</p></sec><sec><title>Результаты</title><p>Результаты. Выявлены статистически значимые различия показателей концентрации внимания между группами низкой и высокой результативности. Для числового показателя концентрации внимания: p = 0,003, d Коэна = 0,65 (средний эффект); для балльного показателя концентрации внимания: p &lt; 0,001, d Коэна = 0,82 (большой эффект). Значимых различий в устойчивости показателя внимания не выявлено (p &gt; 0,05). ROC-анализ подтвердил высокий прогностический потенциал обоих показателей. Для числового показателя: AUC = 0,805 (95% ДИ: 0,627–0,946), оптимальный порог ≤ 0,950, чувствительность 62,5%, специфичность 93,8%, PPV = 90,9%, NPV = 71,4%. Для балльного показателя: AUC = 0,812 (95% ДИ: 0,674–0,938), оптимальный порог — 2 и более балла, чувствительность 87,5%, специфичность 75,0%, PPV = 77,8%, NPV = 85,7%. Балльная оценка концентрации внимания (по трехбалльной шкале) демонстрирует диагностическую точность, сопоставимую с числовым показателем (AUC 0,812 и 0,805 соответственно). Контроль влияния возраста (ранговый ANCOVA) подтвердил независимость выявленных различий (p = 0,007, η2 = 0,26).</p></sec><sec><title>Выводы</title><p>Выводы. Показатели концентрации внимания обладают высокой прогностической ценностью и могут рассматриваться как психофизиологические маркеры для дифференциации нападающих по уровню результативности. Балльная оценка концентрации внимания благодаря сопоставимой диагностической точности и простоте интерпретации может быть рекомендована для практического применения в системе спортивного отбора. Установленные диагностические пороги требуют валидации на расширенных выборках, но уже могут быть использованы в практике спортивного отбора как дополнительные объективные критерии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Attention is a key cognitive process in team sports. In hockey, competitive performance is critically dependent on rapid decision-making and efficient information processing under time pressure. However, the current literature lacks established threshold values for attention metrics that could be used to differentiate players according to their performance level.</p></sec><sec><title>Objective</title><p>Objective. To evaluate the prognostic value of attention concentration and sustained attention metrics as predictors of athletic performance among student hockey forwards.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The cross-sectional study enrolled 50 forwards from the student hockey team of the Urals State University of Physical Culture, with a mean age of 21.9 ± 1.9 years. Sustained attention and concentration were assessed using psychophysiological testing with the NS-PsychoTest hardware-software complex; the results were expressed as quantitative and scoring metrics. Performance was evaluated based on an integral index of technical and tactical actions (TTA), calculated by the coaching staff from the data of official matches. Based on the TTA distribution, players were stratified into three groups: Group 1 (below the 25th percentile; low performance; n = 16), Group 2 (between the 25th and 75th percentiles; moderate performance; n = 18), and Group 3 (above the 75th percentile; high performance; n = 16). Group comparisons were performed using nonparametric Kruskal–Wallis and Mann–Whitney U tests. The effect size was estimated using Cohen’s d. The predictive ability of attention concentration metrics was assessed via Receiver Operating Characteristic (ROC) analysis, including calculation of the area under the curve (AUC), sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV).</p></sec><sec><title>Results</title><p>Results. Statistically significant differences in attention concentration metrics were found between the low- and high-performance groups. For the quantitative attention concentration measure, p = 0.003 and Cohen’s d = 0.65 (medium effect); for the scoring measure, p &lt; 0.001 and Cohen’s d = 0.82 (large effect). ROC analysis confirmed the high predictive potential of both metrics. For the quantitative measure, AUC was 0.805 (95% CI: 0.627–0.946), with an optimal threshold of ≤ 0.950, sensitivity of 62.5%, specificity of 93.8%, PPV of 90.9%, and NPV of 71.4%. For the scoring metric, AUC was 0.812 (95% CI: 0.674–0.938), with an optimal threshold of ≥ 2 points, sensitivity of 87.5%, specificity of 75.0%, PPV of 77.8%, and NPV of 85.7%. The scoring assessment of attention concentration (on a 3-point scale) demonstrated diagnostic accuracy comparable to that of the quantitative metric (AUC: 0.812 vs. 0.805, respectively). Age-related effects were controlled using rank-based ANCOVA, which confirmed the independence of the observed differences (p = 0.007, η2 = 0.26).</p></sec><sec><title>Conclusions</title><p>Conclusions. Attention concentration metrics demonstrated high predictive value and may serve as psychophysiological markers for differentiating forwards by performance level. Given its comparable diagnostic accuracy and ease of interpretation, the scoring-based assessment of attention concentration is recommended for practical application in the system of sports talent selection. The established diagnostic thresholds require validation in larger samples; however, they may already be applied in sports selection practice as additional objective criteria.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>внимание</kwd><kwd>концентрация</kwd><kwd>устойчивость</kwd><kwd>психофизиологические маркеры</kwd><kwd>нападающие</kwd><kwd>студенческая команда</kwd><kwd>хоккей</kwd><kwd>результативность</kwd><kwd>соревновательная деятельность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>attention</kwd><kwd>attention concentration</kwd><kwd>sustained attention</kwd><kwd>psychophysiological markers</kwd><kwd>forwards</kwd><kwd>university team</kwd><kwd>ice hockey</kwd><kwd>performance</kwd><kwd>competitive activity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках исполнения государственного задания НИР на тему «Повышение эффективности спортивной подготовки хоккеистов студенческой хоккейной лиги на основе учета их психофизиологических и технико-тактических характеристик» № 777-00014-25-00 (2025 г.) и № 777-00029-26-00 (2026 г.).</funding-statement><funding-statement xml:lang="en">This study was carried out within the framework of the State Research Assignment No. 777-00014-25-00 (2025) and No. 777-00029-26-00 (2026) on the topic “Improving the Efficiency of Sports Training for Hockey Players in the Student Hockey League Based on Their Psychophysiological and Technical-Tactical Characteristics.”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Kirby ED, Jones K, Campbell N, Fickling SD, D’Arcy RCN.
