Además, la economía de carrera se considera una medida fisiológica importante para los atletas de resistencia, especialmente en los corredores de fondo. El objetivo de esta investigación fue determinar asociaciones entre la activación muscular del core, la cinemática del movimiento y la economía de carrera expresada como el consumo de oxígeno y gasto energético necesario para mantener la carrera a una intensidad sub umbral. Este trabajo se realizó con atletas de fondo en la ciudad de Bogotá D.C. La metodología del estudio se desarrolló en dos fases: una primera fase correspondiente a la caracterización de los deportistas mediante la composición corporal y los parámetros ventilatorios calculados durante una prueba de esfuerzo incremental. En la segunda fase, se realizó la evaluación biomecánica de carrera y la medición del nivel de activación muscular del core durante una prueba de 20 minutos a carga constante por debajo del umbral ventilatorio 2 (VT2). Los resultados de esta investigación permiten concluir la presencia de correlaciones positivas y negativas durante la carrera entre la activación muscular del core y variables cinemáticas de la pelvis y el tronco. Además, se demostró que el movimiento de oblicuidad pélvica y el nivel de activación muscular del erector de la columna presentaron relaciones positivas altas y moderadas con la economía de carrera. (Texto tomado de la fuente)Running economy is a complex and multifactorial concept that reflects the integrated combination of a variety of metabolic, cardiorespiratory, biomechanical, and neuromuscular characteristics specific to each athlete. Additionally, running economy is considered an important physiological measure for endurance athletes, especially distance runners. The objective of this research was to determine associations between core muscle activation, movement kinematics, and running economy expressed as oxygen consumption and energy expenditure needed to maintain running at a subthreshold intensity. This work was carried out with long-distance athletes in the city of Bogotá D.C. The study methodology was developed in two phases: a first phase corresponding to the characterization of athletes through body composition and ventilatory parameters calculated during an incremental stress test. In the second phase, the biomechanical evaluation of running and the measurement of the level of muscle activation of the core during a 20-minute test at constant load below the ventilatory threshold 2 (VT2) were performed. The results of this research allow us to conclude the presence of positive and negative correlations during the race between core muscle activation and kinematic variables of the pelvis and trunk. In addition, pelvic obliquity movement and erector spinae muscle activation level were shown to have high and moderate positive relationships with running economy.Fundación Universitaria del Área AndinaMaestríaMagíster en Fisioterapia del Deporte y la Actividad Física181 páginasapplication/pdfspaUniversidad Nacional de ColombiaBogotá - Medicina - Maestría en Fisioterapia del Deporte y la Actividad FísicaDepartamento de Movimiento Corporal HumanoFacultad de MedicinaBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá610 - Medicina y salud::612 - Fisiología humanaSports medicine-8a. ed.Athletes - medical examinations-8a. ed.MEDICINA DEPORTIVADEPORTISTAS-EXAMENES MEDICOSRunning economyKinematicsBiomechanicCoreAbdominalMuscle ActivityElectromyographyAsociación entre activación muscular del core, variables cinemáticas y economía de carrera, en atletas de fondoAssociation between core muscle activation, kinematic variables and running economy in endurance athletesTrabajo de grado - Maestríainfo:eu-repo/semantics/masterThesisinfo:eu-repo/semantics/acceptedVersionTexthttp://purl.org/redcol/resource_type/TMRedColLaReferenciaAbe D, Muraki S, Yanagawa K, Fukuoka Y, Niihata S.
