Abstract

Speed running analysis using laser sensors allows to obtain data in real-time showing an advantage compared with other systems. The objective of this study was to assess the validity and reliability of the laser sensor of the BioLaserSport® system for the calculation of mean and maximum velocities using relative and absolute statistics tools. The participants were 17 men (20.85 ± 1.54 years). A laser sensor type 1 (LDM301, Jenoptik, Germany) was used to record positions of the subjects to 2000 Hz. The data were analyzed using DSL- 30 routine created with DasyLab v.10.0. A Photogrammetry-2D system with a high-speed camera (Exilim High Speed EX-F1, Casio) and SkillSpector v.1.3.2. (Video4coach, Grubbemollevej) and a reference system 4 x 2 m2 was used. Furthermore, a double photocell (Polifemo Light, Microgate, Italy) with an electronic stopwatch (Microgate, Italy) Racetime2 was used. Three series of 30 m sprint were recorded during two days. The results indicated that the laser sensor provided differences in mean and maximum velocities of -0.11 ms- 1 and 0.14 ms-1, respectively. The correlation coefficients were higher than 0.86 in relation to photogrammetry and higher than 0.92 in relation to photo-cells. The laser system showed an excellent test-retest reliability for mean velocities with a coefficient of correlation intraclass (ICC) between 0.7-0.9. The standard error of the mean (SEM and SEM%), intra-session e inter-session, were lower than, 0.05 ms-1 and 0.12 ms-1, respectively, and in both cases less than 0.75% and 2%, respectively . In relation to maximum velocities, the values were lower than 0.10 ms-1 and 0.17 ms-1, respectively, and in both cases less than 1.36% and 1,89%. The minimum detectable change (MDC and MDC%) intra-session, for both variables, was lower than 0.14 ms-1 and 0.29 ms-1, respectively, (< 2.09% y < 3.76%). In relation to inter-session, the values were lower than 0.34 ms-1 and 0.47 ms-1 (< 5.56% y < 5.25%), respectively. Therefore, the laser system was a useful tool to analyze the evolution of the intra-subject and inter-subject velocity in a 30 m sprint running. Moreover, it provides results in real time, although assessing performance improvements must be considered the SEM, SEM%, MDC and MDC% values.
