Identification of the acceleration phase in the 100 meters dash race attending to kinematic variables

On a few occasions, 100 meter dash phases have been identified through objective variables (Mackala, 2007; Saito et al., 2008). The aim of this study was to develop a tool to identify the acceleration phase in function of the instantaneous velocity race (m·s-1), and to compare it with an initial pha...

The aim of this study was to develop a tool to identify the acceleration phase in function of the instantaneous velocity race (m·s-1), and to compare it with an initial phase of the race calculated through contact time (s) and vertical ground reaction force (N). Five elite male athlete´s whole races were analysed (25±5,76 years old). GebioMized® instrumented pressure insoles and LDM301 Jenoptik laser system measured all the variables. The identification of race phases was realized in function of linear regressions (R2) and of the slope of those linear regressions calculated taking the sections of the race in the variable´s graphics measured in function of time or steps registered.

El objetivo principal de este estudio fue proponer una herramienta de cálculo para identificar la fase de aceleración en función de la velocidad instantánea de carrera (m·s-1) y comparar esta con una fase inicial de carrera calculada a partir del tiempo de apoyo (s) y la fuerza de reacción vertical máxima (N). Se analizaron las carreras completas de cinco atletas varones de élite nacional (25±5,76 años). Las mediciones se realizaron con plantillas instrumentadas GebioMized® y con el sistema láser LDM301 de Jenoptik. La identificación de fases de carrera se realizó en función de regresiones lineales (R2) y de la pendiente de las rectas de regresión lineal calculadas por tramos de carrera en las gráficas de las variables medidas en función del tiempo o los apoyos registrados. El análisis de la fase de aceleración de la carrera, con el sistema de cálculo propuesto, nos permite identificar dos subfases dentro de la misma. No se encontraron similitudes en los resultados obtenidos ni entre los atletas ni entre las variables utilizadas. Con la precaución propia a la que nos obliga la escasa muestra utilizada, se puede concluir que la localización de las fases, de la carrera de 100 m lisos es diferente dependiendo del atleta estudiado y de la variable contempladaActividad Física y Deporte2018info:eu-repo/semantics/articlehttp://hdl.handle.net/10952/6107https://doi.org/10.12800/ccd.v13i37.1037reponame:RIUCAM.
