 <abstract xml:lang="en">
 <p>The aim of this study was to assess the amount of physiological stress experienced as a characteristic of external work during strength exercises (bench press, squat, deadlift) performed at maximum repetitions, at intensities of 100, 90, 80, 70, 60, and 50 % of 1RM. Twelve athletes from various sports participated in the study. A treadmill volitional failure test was used to determine VO2 max and maximum heart rate. A GymAware linear encoder, a MetaLyzer portable ergospirometer, and a Lactate Plus lactate analyzer were used to measure the ergometric and physiological characteristics of physical exercise. To achieve the study's objectives, exercise exposure indices calculated from O2 consumption and heart rate (NEO2 and HRNE) were used. NEO2 and HRNE were strongly linearly correlated across all exercises (r = 0.85-0.95) and with the maximum increase in lactate concentration (∆La) (ρ = 0.81–0.89). Moderate to strong correlations with external mechanical work (A) were found: ρ = 0.65–0.89. The obtained results indicate the possibility of using the NEHR indicator for indirectly assessing the volume of mechanical work performed and the amount of lactate accumulated during the exercise.</p>

 <p>Цель исследования – оценить объем перенесенного физиологического напряжения, как характеристику внешней работы при выполнении силовых упражнений (жим лежа, приседание, становая тяга) в режиме предельных повторений, на уровне интенсивности - 100, 90, 80, 70, 60, 50 % от 1ПМ. В исследовании участвовали 12 спортсменов, из различных видов спорта. Для определения МПК и предельной ЧСС использовали тест с повышением нагрузки до волевого отказа на беговом тредбане. Для измерения эргометрических и физиологических характеристик физической нагрузки использовали линейный энкодер GymAware, портативный эргоспирометр MetaLyzer и анализатор лактата Lactate Plus. Для реализации цели исследования были использованы показатели нагрузочной экспозиции, рассчитанные по потреблению О2 и по ЧСС (НЭО2 и НЭчсс). НЭО2 и НЭчсс во всех упражнениях сильно линейно взаимосвязаны между собой (r = 0,85–0,95) и с максимальным приростом концентрации лактата (∆Ла) (ρ = 0,81–0,89); с внешней механической работой (А) выявлены умеренные и сильные связи: ρ = 0,65–0,89. Полученные результаты свидетельствуют о возможности оценки перенесенного физиологического напряжения, как косвенной характеристики объема выполненной механической работы и величины накопленного лактата в упражнении, с помощью показателя НЭчсс.</p>
