Колебательные и переходные процессы вариабельности сердечного ритма при физической нагрузке

Колебательные и переходные процессы вариабельности сердечного ритма при физической нагрузке

Abstract

С целью выявления колебательных и волновых процессов вариаций периода сердечных сокращений проведено исследование основных закономерностей изменчивости RR-интервалов человека при переходе от его спокойного состояния к состоянию, характеризующемуся воздействием динамической физической нагрузки. Особый интерес представляет поведение сердечно-сосудистой системы при максимальной напряженности нагрузки, когда организм человека находится в условиях, приближенных к максимальному стрессу. На однородной выборке волонтеров (26 человек в возрасте 18-24 лет) представлены основные закономерности вариаций периода сердечных сокращений человека во время нагрузок, мощность которых изменяется в диапазоне от 25 до 210 Вт. Получены функции, описывающие изменения RR- интервалов во время стадий напряжения и в стадиях восстановления в зависимости от заданной мощности, а также найдены параметры этих функций.
