Средний возраст мальчиков составил 9,60 ± 0,05 года, девочек — 9,50 ± 0,05 года. Организация исследования соответствовала требованиям Хельсинкской декларации ВМА. Испытуемые были практически здоровы, занимались физической культурой по общепринятой программе и не посещали спортивные секции. В работе использован комплекс методик, пригодных для исследования физической работоспособности детей школьного возраста в широком диапазоне доступных нагрузок. В ходе исследования выделены 5 основных факторов, определяющих структуру физической работоспособности детей 9-10 лет. Показано, что у мальчиков и девочек на фоне сохранения общей структуры работоспособности по-разному распределены вклады рассматриваемых факторов в обобщённую дисперсию выборки, а также физиологические показатели, входящие в состав отдельных факторов, и их весовые коэффициенты. Установлено, что мальчики 9-10 лет существенно превосходят девочек по уровню физической работоспособности во всём диапазоне доступных нагрузок. При этом наибольшее количество значимых различий выявлено в переменных, характеризующих работоспособность в зонах умеренной и большой мощности, связанных преимущественно с аэробным и смешанным аэробно-анаэробным энергообеспечением мышечной деятельности. Показатели аэробной ёмкости характеризуются наибольшими межгрупповыми различиями по сравнению с другими энергетическими критериями работоспособности. Результаты исследования могут быть использованы при решении прикладных задач по гигиеническому нормированию и контролю величины физических нагрузок различной относительной мощности в процессе физического воспитания мальчиков и девочек 9-10 лет.</p></abstract><trans-abstract xml:lang="en"><p>The study included children referred by their state of health to the main medical group (n=91). The average age of boys amounted to 9.6±0.05 years, and of girls — 9.5±0.05 years. The set of methods suitable for the study of school-aged children’s physical working capability at the wide range of accessible tensions was studied. The arrangement of the study met demands of Helsinki declaration. During the study 5 main factors determining physical working capacity structure in 9-10 aged children under the vast range of accessible tensions were found out. All the children were certainly health, went in for physical exercises according to commonly accepted program and did not attend sport sections. In the work there was used the complex of methods suitable for the study of the physical performance of schoolchildren in the large range of available loads. During the study there were selected 5 main factors determining the structure of the physical performance of children aged of 9-1-0 years. It is shown that boys’ and girls’ against background of the preservation of the common structure of the performance contributions of considered factors to the summarized dispersion of the sample, and physiological indices included in to the pattern of specific factors and their weight coefficients are distributed in various ways. Boys aged of 9-10 years were established to exceed girls by physical working capacity in all ranges of available loads. Meanwhile the greatest number of significant differences was identified concerning the variables characterizing working capacity in the moderate and high power relating with mainly aerobic and mixed aerobic-anaerobic power supply of muscular activity. Indices of aerobic capacity are characterized with the most differential “sensibility” in comparison with other energy criteria of the working capacity. The results of the study can be used in the solution of practical tasks according to hygienic rating and control of the value of physical loads of different relative power during the process of physical education of children aged of 9-10 years.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аэробная и анаэробная производительность</kwd><kwd>зоны относительной мощности</kwd><kwd>факторный анализ</kwd><kwd>половые особенности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aerobic and anaerobic efficiency</kwd><kwd>relative power zones</kwd><kwd>factorial analysis</kwd><kwd>sexual peculiarities</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">Dalbokova D., Krzyzanowski M., Lloyd S., eds.
