The paper compares the results of maximum tests with a stepwise increasing load with different duration of one load step: 15, 30, 60, 120 and 240 s. Maximum oxygen uptake, total operating time, and pair-wise relationship of protocols were assessed. There was no statistically significant difference in maximum oxygen uptake rate in protocols of different duration. Also, all the studied protocols showed a high correlation with each other (r = 0.92–0.97).</p></abstract><trans-abstract xml:lang="ru"><p>Максимальное потребление кислорода является информативным показателем аэробной работоспособности, и его оценка связана с существенными затратами времени. В данной работе проведено сравнение результатов максимальных тестов со ступенчато возрастающей нагрузкой с разной продолжительностью одной ступени нагрузки: 15, 30, 60, 120 и 240 с. Оценивалось максимальное потребление кислорода, общее время работы и парная взаимосвязь протоколов. Было показано отсутствие статистически значимых различий по максимальной скорости потребления кислорода в протоколах с различной продолжительностью. Также все исследуемые протоколы показали высокую корреляцию между собой (<italic>r</italic> = 0.92–0.97).</p></trans-abstract><kwd-group xml:lang="en"><kwd>maximum oxygen consumption</kwd><kwd>aerobic performance</kwd><kwd>incremental test</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>максимальное потребление кислорода (МПК)</kwd><kwd>аэробная работоспособность</kwd><kwd>функциональная диагностика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Lundby C., Montero D., Joyner M.
