Loughborough Soccer Passing Test is reproducible in specific surface to football practice

Abstract

The aim was to verify the test-retest reproducibility of the Loughborough Soccer Passing Test (LSPT) in indoor court and the grassy field. Furthermore, aimed to compare and correlate the results in young football players. Thus, ten participants with of 14.7±0.5 years, height of 173.4±9.1cm, and mass of 61.5±9.0 kg were evaluated in two moments, separated by seven days, using the LSPT Protocol in grassy field and indoor court. The Intraclass Correlation Coefficient values, Coefficient of Variation, Standard Error of Measurement and Level of Agreement suggests that the LSPT is a reproducible protocol to the grassy field. On the indoor court Run Time was 47.8±4.4 s, the Penalties Time of 21.4±9.9 s and the Performance Time of 65.7±13.3 s. In the grassy field, the performance was 49.3±4.2 s, 29±7.4 s, and 76.6±12 s for Run Time (RT), Penalties Time (PenalT) and Performance Time (PerfT), respectively. No statistically significant difference was found for the RT and PerfTime (RT: t=0.10; p=0.36; PerfT: t=0.31; p=0.17). However, for the PenalT there was no difference between the values obtained (t=0.14; p=0.02). Statistically significant correlations were not identified for RT variables (r=0.59; p=0.07) and PenalT (r=0.49; p=0.15), but for the PerfT was found a significant correlation (r=0.64; p=0.04). It is concluded that the LSPT is specific skill assessment tool to pass in football practice specific surface. Still, there was no statistically significant difference in LSPT performance between different surfaces, although more penalties were verified in the grassy field. The correlation between the variable of time in LSPT performance between the different surfaces suggests that the protocols show the same goal of evaluation.
