Измеряли длительность задержки дыхания, количество силовых движений, параметры вариабельности сердечного ритма и электромиографии.</p></sec><sec><title>Результаты</title><p>Результаты: после гиповентиляционной тренировки спортсменов в покое усилились парасимпатические влияния на сердечный ритм, что привело к увеличению общей мощности спектра сердечного ритма с 3201 ± 520 до 4047 ± 585 мс2, мощности низкой частоты спектра сердечного ритма — с 1458 ± 216 до 2055 ± 392 мс2 и стандартного отклонения длительности смежных сердечных циклов — с 45 ± 5 до 52 ± 4 мс. При нагрузке на фоне максимальной произвольной задержки дыхания симпатические влияния усилились. Чем длительнее была максимальная произвольная задержка дыхания, тем больше силовых движений совершали спортсмены.</p></sec><sec><title>Заключение</title><p>Заключение: гиповентиляционные тренировки изменяли вагосимпатический баланс организма спортсменов, увеличивая их работоспособность и гипоксическую устойчивость.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective: to study the variability of the heart rate of athletes during hypoventilation training, which provides an increase in the result of speed-strength load.</p></sec><sec><title>Materials and methods</title><p>Materials and methods: Athletes performed speed-strength load with their hands on a training apparatus against the background of maximum voluntary breath holding before and after hypoventilation training. The duration of breath holding, the number of power movements, parameters of heart rate variability and electromyography were measured.</p></sec><sec><title>Results</title><p>Results: After hypoventilation training of athletes at rest, parasympathetic influences on the heart rate increased, which led to an increase in the total power of the heart rate spectrum from 3201 ± 520 to 4047 ± 585 ms2, the power of the low frequency of the heart rate spectrum from 1458 ± 216 to 2055 ± 392 ms2 and the standard deviation of the duration of adjacent cardiac cycles from 45 ± 5 to 52 ± 4 ms. Sympathetic influences increased during exercise against the background of maximum voluntary breath holding.
