The purpose of this study was to examine the length of intervals QT, QT dispersion during intermittent normobaric hypoxic training in high level athletes. There was found out a significant increase of QT interval during exposure of intermittent normobaric hypoxia in high level athletes. However, it didn’t reach clinically significant (arrythmogenic) value. While the length of corrected QT interval, QT dispersion didn’t significantly change either. The application of intermittent normobaric hypoxia trainings consists of six intervals of five minutes breathing hypoxic (10 % oxygen) air, alternated with intervals of five minutes breathing ambient air didn’t lead to clinical significant increase intervals QT and QT dispersion in high level female athletes.
В работе изучена длительность интервала QT, дисперсии интервала QT у спортсменов высокой квалификации при воздействии прерывистой нормобарической гипоксии. Использование у спортсменок высокой квалификации прерывистой нормобарической гипоксии в режиме чередования шести 5-минутных циклов гипоксии с дыханием газовой смесью с 10 % содержанием кислорода с 5-минутными интервалами отдыха с дыханием атмосферным воздухом не ведет к клинически значимым изменениям длительности интервала QT и дисперсии интервала QT при исходно нормальном их уровне.
