Здоровые люди могут испытывать одышку в различных ситуациях — на большой высоте, после задержки дыхания, во время стрессовых ситуаций, вызывающих тревогу или панику, чаще всего при напряженных физических нагрузках. Однако сведения о вариабельности восприятия одышки у здоровых людей на сегодня недостаточны. В данном исследовании оценивали вариабельность восприятия одышки у здоровых людей в условиях дополнительного респираторного сопротивления.</p><p>Цель исследвания — оценить вариабельность восприятия одышки у здоровых лиц при дыхании на фоне ступенчатого увеличения дополнительного респираторного сопротивления, а также провести оценку связи между уровнем восприятия одышки и уровнем физической активности.</p></sec><sec><title>Методы</title><p>Методы. Проведено одномоментное наблюдательное поисковое исследование с участием здоровых людей в возрасте 19–25 лет. Исследование проводилось на базе кафедры патофизиологии федерального государственного бюджетного образовательного учреждения высшего образования «Рязанский государственный медицинский университет имени академика И. П. Павлова» Министерства здравоохранения Российской Федерации в период с ноября 2018 по июнь 2019 г. Всего было исследовано 42 испытуемых. Испытуемые подвергались действию дополнительного респираторного сопротивления, при котором уровень восприятия одышки количественно оценивался по модифицированной шкале Борга, и были разделены на три группы по уровню восприятия одышки в соответствии с тертилями шкалы Борга: группа с низким восприятием (оценка Борга &lt; 2; n = 13), группа среднего восприятия (оценка Борга 2–5; n = 19) и группа высокого восприятия одышки (оценка Борга &gt; 5, n = 13). Определяли индекс массы тела, оценивали максимальное давление в дыхательных путях, выполняли тесты функции легких, проводили исследование физической активности (вопросник IPAQ (international questionnaire on physical activity)) и тест шестиминутной ходьбы (6MWT (6 minutes walking test)). Анализ данных проводили с помощью программного пакета IBM SPSS Statistics, версия 17.0 (США).</p></sec><sec><title>Результаты</title><p>Результаты. В исследование были включены 42 здоровых испытуемых. Уровень восприятия одышки был классифицирован как низкий, средний и высокий у 13, 19 и 10 человек соответственно. Уровень восприятия одышки не был значимо связан с возрастом, полом, индексом массы тела, оценкой физической активности, максимальным давлением в дыхательных путях или результатами исследования функции легких.</p></sec><sec><title>Заключение</title><p>Заключение. Показатели воспринимаемой одышки, вызванной ступенчато увеличивающимся дополнительным респираторным сопротивлением, значительно различались. Восприятие одышки было классифицировано как низкое у 31% испытуемых, среднее у 45% и высокое у 24%. Не было выявлено связи между уровнем восприятия одышки и уровнем физической активности (тест IPAQ или дистанция шестиминутной ходьбы).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. In various situations healthy people may experience breathlessness caused by high altitude, breath-holding, anxiety or panic driven by stressful events, and, very often by physical activity. However, variability in perception of dyspnea in healthy individuals is yet to be explored. The present study analyzes the variability of dyspnea perception in healthy people in the context of additional respiratory resistance.</p><p>Objective — to assess the variability in perception of dyspnea in healthy individuals against a step-up increase in additional respiratory resistance, and to evaluate the relationship between dyspnea perception and physical activity levels.</p></sec><sec><title>Methods</title><p>Methods. A cross-sectional observational exploratory study involved healthy individuals aged 19–25. The study was conducted at the Department of Pathophysiology, Ryazan State Medical University named after acad. I.P. Pavlov (Russia), in the period from November 2018 to June 2019. A total number of individuals under study comprised 42. Study participants were subjected to additional respiratory resistance, when dyspnea perception was estimated using a modified Borg scale. Then all participants were divided into three groups according to the tertiles in their perception: slight perception (Borg score &lt; 2; n = 13), moderate perception (Borg score 2–5; n = 19) and high perception (Borg score &gt; 5, n = 13). The study involved determination of body mass index, maximal airway pressure, pulmonary function, physical activity by means of IPAQ (International Physical Activity Questionnaire) and 6MWT (6 Minute Walking Test). Data analysis was performed using IBM SPSS Statistics 17.0 (USA).</p></sec><sec><title>Results</title><p>Results. The study included 42 healthy individuals. The level of dyspnea perception was determined as slight (low), moderate (medium) and high in 13, 19 and 10 participants, respectively. Perceived level of breathlessness did not significantly correlate with age, gender, body mass index, physical activity, maximum airway pressure or pulmonary function test results.</p></sec><sec><title>Conclusion</title><p>Conclusion. Perceived dyspnea caused by a step-up increase in additional respiratory resistance varied significantly. The perception of dyspnea was determined as slight in 31% of participants, moderate in 45% and high in 24%. The authors did not reveal a correlation between dyspnea perception and physical activity level (via IPAQ or 6 Minute Walking Test).</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>одышка</kwd><kwd>дополнительное респираторное сопротивление</kwd><kwd>уровень физической активности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dyspnea</kwd><kwd>additional respiratory resistance</kwd><kwd>physical activity level</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы заявляют об отсутствии спонсорской поддержки при проведении исследования</funding-statement><funding-statement xml:lang="en">the authors declare that no funding was received for this study</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">Kašiković Lečić S., Javorac J., Živanović D., Lovrenski A., Tegeltija D., Zvekić Svorcan J., Maksimović J.
