Качество воздушной среды помещений спортивного вуза определяет комфортность учебного и тренировочного процессов и может рассматриваться как фактор риска здоровью студентов.</p><p>Цель – гигиеническая оценка изменения концентраций СО2 в воздухе учебных помещений спортивного вуза в течение учебного дня.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Были проведены замеры в 12 учебных, 6 лекционных аудиториях, 3 спортивных и тренажерном залах. Субъективная оценка качества воздуха в учебных помещениях анализировалась по результатам анкетирования 651 студента.</p></sec><sec><title>Результаты</title><p>Результаты. Различия в удельном весе проб, не соответствующих гигиеническим нормативам, между группами учебных помещений незначительны и составили от 32 ± 4,66 % до 41,33 ± 2,84 % в холодный период (ХП) и от 42,33 ± 2,85 % до 49,33 ± 4,08 % в теплый период (ТП). Среднее значение концентраций СО2 в нестандартных пробах составило 1132,11 ± 93,21 ppm в ХП и 1124,98 ± 98,51 ppm в ТП. Выявлено, что концентрации СО2 в воздухе в ХП к 15.40 превышали допустимое содержание в 100 % учебных аудиторий, в 50 % лекционных залов и тренажерном зале, а к концу учебного дня в 100 % обследованных аудиторий. В ТП в тренажерном зале и в 33,3 % лекционных аудиторий наблюдалось превышение допустимых значений уже к 13.00, а к 15.40 превышения наблюдались в 100 % обследованных помещений. Результаты субъективной оценки качества воздуха показали, что большинство студентов часто жалуются на духоту в учебных помещениях; 25,25 ± 1,2 % опрошенных указали на наличие сильного запаха в спортивных и тренажерном залах.</p></sec><sec><title>Выводы</title><p>Выводы. В значительной части учебных помещений концентрации СО2 не превышают допустимых значений в течение более 80 % времени учебного дня. Тем не менее, после четвертого учебного занятия данный показатель выходил за пределы нормативных значений и к концу учебного дня в 100 % обследованных помещений наблюдалось превышение допустимого содержания CO2.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction: Air quality of the premises of a sports university determines comfort and effectiveness of the educational and training processes and can be considered as a risk factor for students’ health.</p><p>The purpose of our study was to give a hygienic assessment of changes in the indoor CO2 concentration at a sports university during the school day.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: Air quality measurements were taken in twelve classrooms, six lecture halls, three sports halls, and a gym. The subjective assessment of air quality in classrooms was analyzed using data of a questionnaire­based survey of 651 students.</p></sec><sec><title>Results</title><p>Results: We found that differences in the proportion of air samples with elevated CO2 concentrations between the rooms were insignificant and ranged from 32 ± 4.66 % to 41.33 ± 2.84 % in the cold season (CS) and from 42.33 ± 2.85 % to 49.33 ± 4.08 % in the warm season (WS). Average CO2 concentrations in non­standard samples were 1,132.11 ± 93.21 ppm and 1,124.98 ± 98.51 ppm in the cold and warm season, respectively. We established that in the cold season, indoor CO2 concentration exceeded the permissible limit in 100 % of the classrooms, 50 % of the lecture halls and the gym already by 3.40 p.m. (15:40); by the end of the school day, the excess was registered in 100 % of the university rooms. In the warm season, CO2 concentrations were above the limit in the gym and in 33.3% of the lecture halls by 1 p.m. (13:00), and by 3.40 p.m. the excess was observed in 100 % of the rooms examined. Subjective air quality assessments indicated that most students often complained about stuffiness in classrooms; 25.25 ± 1.2 % of the respondents mentioned a strong odor in sports halls and the gym.</p></sec><sec><title>Conclusion</title><p>Conclusion: In a significant part of sports university rooms, CO2 concentrations did not exceed permissible values for more than 80 % of school hours. Yet, after the fourth double lesson, this air quality indicator went beyond the standard value, and by the end of the school day indoor concentrations of carbon dioxide were above the permissible limit in 100 % of the university rooms.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диоксид углерода</kwd><kwd>воздух общественных зданий</kwd><kwd>учебные помещения</kwd><kwd>спортивные залы</kwd><kwd>студенты­спортсмены</kwd><kwd>анкетирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbon dioxide</kwd><kwd>indoor air quality</kwd><kwd>classrooms</kwd><kwd>gyms</kwd><kwd>student athletes</kwd><kwd>a questionnaire­based survey</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Толмачёв Д.А., Мухаметзянов Р.Р., Минниярова А.И.
