Resum

The purpose of this study was to analyze the kinematic variables of both steeplechase and steeplechase water jumps, their relationship with performance, and the influence of some factors such as gender and fatigue during a 3000 m steeplechase competition. Two races of the XVII Athletics Meeting Ciudad de Mataró (National Trials for London-2012 Olympic Games) were recorded. Thirty-five athletes were analyzed (19 male and 16 female) and classified into 3 groups according to their competition performance level compared to the World Record. Images were digitalized by a 2D kinematic analysis (Kinescan-IBV). The results showed that some biomechanical variables of the steeplechase jump (steeplechase velocity, step length and percentage of flight time) and steeplechase water jump (steeplechase velocity and its decrease over the laps) were related to performance. Other variables were sensitive to the gender (steeplechase jump: steeplechase/competition velocity ratio and step length/steeplechase velocity ratio; steeplechase water jump: steeplechase/competition velocity ratio). The variables which were not related to performance, gender or fatigue allowed establishing reference values for training (e.g. takeoff distance of ~53-55% in the steeplechase jump and ~35-39% in the steeplechase water jump). In conclusion, this is the first study that simultaneously analyzed the biomechanics of both steeplechase and steeplechase water jumps during a 3000 m steeplechase competition, relating biomechanical variables to performance and gender. The comparisons with respect to previous studies indicated that the females had a short step length in the steeplechase, and that both male and female should improve their steeplechase water jump technique.
