BACKGROUND: No gold standard criteria exist for return to sport decision-making. The Butterfly Agility Test (BAT) has been shown to be a valid and reliable test for assessing various aspects of athletic performance; however, the space required to conduct it may be prohibitive for clinical environments and it has not been validated among an athletic population. PURPOSE: To determine the reliability of the modified BAT (mBAT) and the number practice trials required to optimize its reliability. A secondary purpose was to assess the preliminary validity of the mBAT associated with the Y-Balance Test (YBT) and its relationship with player position among competitive soccer athletes. STUDY DESIGN: Multi-phase reliability and validity study. METHODS: Phases I and II involved 25 healthy adults (72% female, mean age = 23.4 years) and 45 competitive soccer athletes (55% female, mean age = 18.2 years), respectively. In Phase I, subjects performed 10 consecutive trials of the mBAT to assess test-retest and inter-rater reliability of the mBAT. In Phase II, subjects completed two consecutive trials of the mBAT and YBT during the pre-season period. Intraclass correlation coefficients were used to assess the reliability of the mBAT and repeated measures analysis of variance (ANOVA) was used to assess differences between trials in Phase I. In Phase II, Pearson's product-moment correlation coefficient was used to assess the relationship between mBAT and YBT performance and an ANOVA was used to assess differences in mBAT and YBT performance between player positions. RESULTS: In Phase I, the mBAT demonstrated excellent reliability (ICC = 0.92-1.00). In Phase II, female collegiate athletes performed better than male high-school athletes on the mBAT (p = 0.01). No significant relationships were found between the mBAT or YBT with player position (p > 0.26). CONCLUSION: The mBAT is a reliable physical performance test and three practice trials are recommended prior to recorded trials. The validity of the mBAT for distinguishing athletic performance remains inconclusive, although it appears the mBAT measures a distinct aspect of physical performance compared to the YBT. Although this data is preliminary, the mBAT shows promise as a useful tool for clinicians, trainers, and coaches to assess physical performance among competitive soccer athletes. Larger prospective studies are warranted prior to utilizing the mBAT for clinical decision-making. LEVEL OF EVIDENCE: 3b.
背景：对于恢复运动的决策，不存在金标准标准。蝴蝶敏捷性测试（BAT）已被证明是一种评估运动表现各个方面的有效且可靠的测试；然而，进行该测试所需的空间可能在临床环境中难以满足，并且它尚未在运动员群体中得到验证。 目的：确定改良版BAT（mBAT）的可靠性以及优化其可靠性所需的练习试验次数。第二个目的是评估与Y平衡测试（YBT）相关的mBAT的初步有效性及其与竞技足球运动员球员位置的关系。 研究设计：多阶段可靠性和有效性研究。 方法：第一阶段和第二阶段分别涉及25名健康成年人（72%为女性，平均年龄 = 23.4岁）和45名竞技足球运动员（55%为女性，平均年龄 = 18.2岁）。在第一阶段，受试者连续进行10次mBAT试验，以评估mBAT的重测可靠性和评分者间可靠性。在第二阶段，受试者在季前赛期间完成两次连续的mBAT和YBT试验。组内相关系数用于评估mBAT的可靠性，重复测量方差分析（ANOVA）用于评估第一阶段试验之间的差异。在第二阶段，皮尔逊积矩相关系数用于评估mBAT和YBT表现之间的关系，ANOVA用于评估球员位置之间mBAT和YBT表现的差异。 结果：在第一阶段，mBAT表现出出色的可靠性（ICC = 0.92 - 1.00）。在第二阶段，大学女运动员在mBAT上的表现优于高中男运动员（p = 0.01）。未发现mBAT或YBT与球员位置之间存在显著关系（p > 0.26）。 结论：mBAT是一种可靠的身体性能测试，建议在记录试验前进行三次练习试验。尽管与YBT相比，mBAT似乎测量了身体性能的一个独特方面，但mBAT区分运动表现的有效性仍不确定。虽然这些数据是初步的，但mBAT有望成为临床医生、训练师和教练评估竞技足球运动员身体性能的有用工具。在将mBAT用于临床决策之前，有必要进行更大规模的前瞻性研究。 证据水平：3b。
