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...

| Sumario: | 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 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. Acceleration phase analysis, realized with the calculation system exposed, allow us to identify two subphases within the above. Similarities among the athletes nor between the analyzed variables were not identified. Taking into account the small sample in our study, it can be concluded that the situation of phases at 100 meters dash race is different depending on the studied athlete or variable |
