Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
The aim of this study was to examine the applicability of a test for change of direction ability (10-8-8-10 test, involving line and sideward sprinting, 36 m) in elite-level soccer assistant referees (ARs). One hundred AR of the first-second and third Italian Championships (AR and AR , n = 50, respectively) performed the 10-8-8-10 on 3 separate occasions. Twenty AR authorities scored test relevance (1-5 scale, from trivial to very large) for logical validity using a questionnaire. Construct validity was examined comparing AR and AR for the 10-8-8-10 performance. Short-term reliability was assessed testing a random selection of ARs (n = 64) over 3 separate occasions every other day. Performance in the 10-8-8-10 test was assumed as total coverage time using telemetric photocells. Results showed that the 10-8-8-10 test was perceived as possessing from large (n = 4/20) to very-large (n = 16/20) relevance to AR physical match performance. No significant performance difference was found between competitive levels (p = 0.57). Area under the curve (= 0.49; p = 0.87) showed no significant sensitivity of10-8-8-10 in detecting competitive-level difference. The intraclass correlation coefficient (n = 64) and typical error of measurement (test 2 vs. 3) values were 0.90 (p < 0.0001) and 0.18 seconds, respectively. This study showed that the 10-8-8-10 test possesses logical validity, good reliability, and it is independent of the competitive level. As such, this original investigation represents the first step in the identification and assessment of a valid and reliable AR change of direction test. Given the strength of our findings, governing bodies should look to integrate the 10-8-8-10 test into the fitness test protocols devised for ARs, with scores ≥9.67 being considered as a starting point for the empirical validation of minimum selection criteria for elite-level ARs. © 2011 National Strength and Conditioning Association.
