Abstract

The reliability and feasibility of a 2-2 shuffle test time against on-court lateral change of direction performance was examined. Ten male national league players performed two trials of the 2-2 shuffle test per direction and were compared against their total steals throughout the season. Intraday reliability of the test was computed using Bland-Altman plots, intraclass correlation coefficients (ICCs) and coefficients of variations (CVs). Anthropometric and total steals differences between fast and slow 2-2 shuffle performance were assessed with an independent t-test, percent difference (Diff %), and effect size (ES). The 2-2 shuffle test time for dominant (ICC = 0.86, CV = 8.61%) and non-dominant (ICC = 0.90, CV = 9.30%) directions met pre-determined reliability thresholds (ICC > 0.8, CV < 10%). Faster 2-2 shufflers were significantly shorter (1.91 ± 0.03 vs. 2.02 ± 0.09, Diff % -5.45, p = 0.03, ES = -1.3) in height and accrued more total steals than their slower counterparts (15.60 ± 9.24 vs. 9.00 ± 6.44, Diff % 42.31, p = 0.22, ES = -0.8). Practitioners may add the 2-2 shuffle to their assessment battery as the test time is a reliable metric and can show the direction for on-court lateral performance as reflected by total steals.

摘要

研究了2-2洗牌测试时间与场上横向变向表现的可靠性和可行性。十名男性国家联盟球员每个方向进行两次2-2洗牌测试,并与他们整个赛季的总抢断数进行比较。使用布兰德-奥特曼图、组内相关系数(ICC)和变异系数(CV)计算测试的日内可靠性。用独立t检验、百分比差异(Diff%)和效应量(ES)评估快速和慢速2-2洗牌表现之间的人体测量学差异和总抢断数差异。优势方向(ICC = 0.86,CV = 8.61%)和非优势方向(ICC = 0.90,CV = 9.30%)的2-2洗牌测试时间达到了预先确定的可靠性阈值(ICC > 0.8,CV < 10%)。更快的2-2洗牌者身高明显更矮(1.91±0.03对2.02±0.09,Diff% -5.45,p = 0.03,ES = -1.3),并且比速度较慢的对手总抢断数更多(15.60±9.24对9.00±6.44,Diff% 42.31,p = 0.22,ES = -0.8)。从业者可以将2-2洗牌测试添加到他们的评估项目中,因为测试时间是一个可靠的指标,并且可以显示总抢断数所反映的场上横向表现的方向。
