El objetivo de este estudio fue analizar la relación entre la producción de potencia en ciclismo, y variables analíticas de core, como la fuerza, la estabilidad y la cinemática durante el pedaleo. En este estudio participaron 30 ciclistas de tres disciplinas, los cuales realizaron un test de estabilidad sedente, un test de fuerza de extensores y flexores de tronco y un test de potencia en ciclismo, donde se analizó la cinemática del tronco. Se encontró una mayor estabilidad sedente en los ciclistas de mountain bike, una mayor inclinación anterior torácica en ciclistas de carretera y un mayor rango de inclinación lateral en triatletas. Solo se encontraron correlaciones significativas entre la inclinación anterior torácica y la potencia crítica. En conclusión, tanto la fuerza como la estabilidad de tronco tienen una baja influencia en la producción de potencia, aunque sí existen diferencias entre las distintas disciplinas en las dimensiones del core.

Palabras clave: fuerza de Tronco; estabilidad de tronco; rendimiento; umbral de potencia funcional.

Abstract

The purpose of this study was to analyse the relationship between cycling power production and core analytical variables, such as strength, stability, and kinematics during pedalling. 30 cyclists from three disciplines participated in this study, who performed a sitting stability test, a trunk flexor and extensors strength test, and a cycling power test (FTP), where trunk kinematics were analysed. Greater seated stability was found in mountain bike cyclists, a greater anterior thoracic tilt in road cyclists, and a greater range of lateral tilt in triathletes. Only significant correlations were found between thoracic anterior tilt and critical power. In conclusion, both the strength and the stability of the trunk had a low influence on the power production, although there are differences between the different cycling disciplines in the dimensions of the core.

Keywords: core strength; core stability; performance: functional threshold power.
