Validation of the Loughborough Soccer Passing Test in young soccer players.

The aim of this study was to examine the validity and reliability of the Loughborough Soccer Passing Test (LSPT) in adolescent soccer players. Eighty-seven players, aged 14-17 years, were recruited according to their playing level: elite (n = 44), sub-elite (n = 22), and non-elite (n = 21). Two attempts of the LSPT were performed at baseline. Players then completed 10 attempts over 3 weeks to familiarize themselves with the test. Subsequently, 2 main trials, separated by 1 week, were performed; the mean of the 2 attempts was recorded as the performance score. After familiarization, the performance scores showed significant differences (p < 0.01) between elite (40.3 ± 8.3 seconds), sub-elite (58.1 ± 10.2 seconds), and non-elite players (66.6 ± 11.7 seconds). There was low-to-moderate reliability between trials with sub-elite (r = 0.35, p < 0.05) and non-elite players (r = 0.47, p < 0.05), but very good for elite players (r = 0.96, p < 0.05). Scores at baseline were better (p < 0.05) for elite players (51.0 ± 9.3 seconds) compared with sub-elite (60.8 ± 8.2 seconds) and non-elite players (69.0 ± 11.1 seconds). The LSPT seems to be a valid and reliable protocol to assess differences in soccer skill performance in adolescent players and can distinguish players according to their playing level. The LSPT was able to distinguish different abilities without players undergoing any familiarization with the test, thus enabling it to be used for talent identification purposes.

Association of short-passing ability with athletic performances in youth soccer players.

PURPOSE: This study was designed to examine the relationship between multiple short-passing ability [measured using the Loughborough Soccer Passing Test (LSPT)] and athletic performances in youth soccer players. METHODS: Forty-two young soccer players (age 14.8±0.4years) performed the LSPT, the squat-jump (SqJ), the counter movement jump (CMJ), the 30m sprints (with 5m and 20m split times also recorded), the 15m agility run (Agility-15m), the 15m ball dribbling (Ball-15m), the Illinois agility test (IAGT) and the Yo-Yo IRT Level 1 tests. RESULTS: LSPT total performance (LSPT TP) showed significant positive correlation with 5m, 20m, and 30m sprint times, Agility-15m, Ball-15m and Illinois agility test (r=0.60, r=0.58, r=0.49, r=0.75, r=0.71 and r=0.72; P<0.01, respectively). Significant negative correlation were found between LSPT TP and SqJ and CMJ (r=-0.62 and r=-0.64; P<0.01, respectively). It was determined that Agility-15m, Illinois agility test and Ball-15m were the most effective factors associated with LSPT TP among other factors in multiple regression analysis. CONCLUSION: This study showed that LSPT TP of young elite soccer players is determined by their agility abilities, thus enabling this test to be used for talent identification purposes.
