Resumen
The purpose was to analyze the influence of the timing gate´s technology on both running time performance and its reliability during short sprint distances. Twenty-five physical students participated (20.5±0.5 yr; 1.78±0.02 m; 77.5±1.8 kg), whose were evaluated during 3 separate days (2 familiarization sessions and 1 testing session). Three standing-start and 3 flying-start runs were randomized and simultaneously registered at 5, 10 and 15 m by two timing gates DSD Laser System®: single- and dual-beam. The type of timing gates affected the performance (F=11.92 y p<0.001) and the reliability (F=14.52 y p<0.001). During the standing-start runs, the single-beam system overestimated (~0.02 s) the performance with respect to the dual-beam one (F=42.95 y p<0.001), and the reliability was acceptable (CCI>0.80) at the distances of 10 and 5 m, respectively. During the flying-start runs, both systems obtained a very similar registry (differences of ~0.005 s), and the reliability was acceptable at the distances of 15 and 10 m, respectively. In conclusion, during the standing-start runs the minimum distance to registry the performance with a single-beam system should be 10 m, and 5 m with a dual-beam system. During the flying-start runs these distances should be 15 and 10 m, respectively. Further studies should analyze the optimal distance to the first timing gate during the standing-start runs, in order to improve the reliability and to compare the performances which were obtained in different studies.
