Параметры эргоспирометрии при бронхоспазме физической нагрузки, взаимосвязь показателей кардиореспираторного тестирования с фракцией no в выдыхаемом воздухе у лыжников и биатлонистов

Abstract

Изучены параметры эргоспирометрии у лыжников и биатлонистов с бронхоспазмом, вызванным физической нагрузкой, а также исследована взаимосвязь между данными показателями и интенсивностью респираторной продукции NO в данных видах спорта. Обследовано 52 лыжника и биатлониста в возрасте 18,8 ± 0,6 лет. Эргоспирометрическое исследование выполнялось на аппарате Oxycon Mobile (Jaeger, Германия) с использованием тредмил-теста. Для выявления БФН исходно и через 1, 5 и 10 минут после нагрузочного теста проводилась форсированная спирометрия. Определение фракции NO в выдыхаемом воздухе (NOвыд) также выполнялось до и после нагрузки. В группе спортсменов мужского пола выявлены достоверно большие эргоспирометрические показатели (VE, VO2). Определена взаимосвязь некоторых показателей, характеризующих аэробную емкость, с NOвыд у спортсменов (VO2, мл/мин/кг & NOвыд, rs = 0,4; p < 0,05; VO2/ЧСС, абс & ΔNOвыд, rs = –0,5; p < 0,05). Спортсмены с БФН продемонстрировали достоверно большие показатели VE на уровне анаэробного порога и VO2/ЧСС, %. Установлено пороговое значение VE (АП) = 110 л/мин, превышение которого может рассматриваться в качестве дополнительного параметра скрининга БФН при прогностической ценности отрицательного результата 71,4 %. Заключение. Спортсмены с уровнем минутной вентиляции на уровне анаэробного порога 110 л/мин и более формируют группу риска по развитию БФН. Определена положительная взаимосвязь между параметрами аэробной производительности и фракцией NO в выдыхаемом воздухе.

The purpose of the study – to investigate cardiorespiratory parameters in skiers and biathlonists with exercise-induced bronchoconstriction (EIB), to search for the relationship between these indicators and the intensity of respiratory NO production in sports. Materials and methods. 52 skiers and biathlonists aged 18,8 ± 0,6 years were examined. Cardiopulmonary exercise testing (CPET) was performed using Oxycon Mobile (Jaeger, Germany) in treadmill-test with the assessment of oxygen uptake (VO2), voluntary ventilation (VE), oxygen pulse (VO2/HR), anaerobic threshold (AT) etc. EIB was screened by baseline and post-exercise forced spirometry at 1st, 5th and 10th minute after the test. Preand post-exercise fractional exhaled NO levels (FeNO) were studied. Results. In males athletes significantly greater CPET functional parameters were identified (VE, VO2). The correlation between aerobic capacity parameters and FeNO was noticed (VO2, ml/min/kg & FeNO, rs = 0,4; p < 0,05; VO2/HR, abs & ΔFeNO, rs = –0,5; p < 0,05). EIB-positive athletes demonstrated significantly higher ventilation rate at the anaerobic threshold and oxygen pulse rate. The level of VE at the anaerobic threshold ≥ 110 l/min may be considered as an additional EIB screening tool with negative predictive value of 71,4 %. Conclusion. The level of VE at the anaerobic threshold ≥ 110 l/min is the risk factor of EIB development. A positive correlation between CPET functional parameters and FeNO level was estimated.
