Validity of the Actiheart step test for the estimation of maximum oxygen consumption in endurance athletes and healthy controls

Abstract: Submaximal step tests are often used for estimation of maximum oxygen consumption (VO2max) in humans. The validity of the Actiheart step test for VO2max estimation was not fully studied yet. Therefore, purpose of the study was to estimate VO2max using the Actiheart step test and to compare the data with measured VO2max in endurance trained athletes (ATH) and healthy non-athletes (CON).68 ATH (54% men, 28.0±5.4 yrs, 20.9±1.7 kg∙m-2) and 63 CON (46% men, 27.6±5.1 yrs, 22.1±1.7 kg∙m-2) performed the Actiheart ste… Show more

“…Individual heart rate calibration was derived from a submaximal step test (Actiheart software version 5.0.5) on day zero (Heydenreich et al., 2019 ), excluding participant 10, who was injured. Actiheart was worn at all times, excluding showers, with daily placement checked by a trained female researcher.…”

“…Prior to free-living monitoring, participants performed a step test for 5-minutes and followed by 2-minutes recovery period for individual calibration of the relationship between heart rate and energy expenditure ( 34 ). In addition, heart rate recorded during the step test was used to determine the estimated maximum uptake of oxygen during exercise (VO 2 max (mLO 2 /kg/min) using Tanaka equation ( 21 , 36 ). Physical activity and cardiorespiratory fitness markers were the main independent variables.…”

“…Similarly, cardiorespiratory fitness has been assessed using maximum uptake of oxygen during exercise (VO 2 max) with walk test or step test (18). More recently, a combined accelerometer and heart rate monitor has been found to be accurate in producing both physical activity energy expenditure and cardiorespiratory fitness data (19)(20)(21)(22). The method is easier to apply and has been previously applied in Africa including among people living with HIV (23, 24).…”

“…Adaptándose a las disposiciones de aislamiento y utilizando los recursos disponibles en cada sitio de confinamiento del jugador para la evaluación del consumo máximo de oxígeno, se utilizó el Chester Step Test (Heydenreich et al, 2019), el cual permitió evaluar la capacidad aeróbica del deportista. El test consta de 5 etapas, 1º etapa: 15 pasos/min, 2º etapa: 20 pasos/min, 3º etapa: 25 pasos/min, 4º etapa: 30 pasos/min y 5º Etapa: 35 pasos/min; donde el evaluado debía subir y bajar un escalón de 30 cm de altura; para marcar el ritmo de ejecución de la prueba se utilizó un audio que determinó los pasos por minuto que ejecutó el evaluado al subir y al bajar, el test marca una velocidad establecida por el latido del metrónomo de dicho audio grabado previamente donde la velocidad inicial es de 15 pasos por minuto y cada 2 minutos el tiempo aumentó en 5 pasos por minuto.…”
