Schneider, C, Rothschild, J, and Uthoff, A. Change-of-direction speed assessments and testing procedures in tennis: a systematic review. J Strength Cond Res 37(9): 1888-1895, 2023-Change-of-direction speed (CODS) plays an essential role in tennis match play, and CODS performance is, therefore, commonly assessed and monitored in tennis players. Thus, the aim of this systematic review was to describe test characteristics, performance metrics, test-retest reliability, construct validity, and test outcomes of tests that are used to assess CODS in tennis players. A literature search conducted on PubMed and SPORTDiscus yielded 563 results. After applying the eligibility criteria, a total of 27 studies were included in the present review. Ten unique CODS tests were identified. 505 test variations were most frequently used across all studies, and total time required to complete the test was the predominant performance metric investigated. Intrasession test-retest reliability ranged from "moderate" to "excellent." Intersession test-retest reliability as well as the effects of tennis performance, sex, and age on CODS performance were unclear given the subject demographics and the limited number of studies that investigated these aspects. In conclusion, most studies included CODS tests that exhibit longer COD entry and total distances but similar COD angles to those seen during tennis match play. All CODS tests have at least "moderate" intrasession test-retest reliability. However, to improve CODS assessment methods and to increase our current understanding of CODS performance in tennis players, there is a need to conduct more research on the intersession test-retest reliability, construct validity, and the effects of sex, age, and tennis performance and to investigate other performance metrics that might provide additional insights into CODS (e.g., phase-specific performance variables).
施耐德、罗斯柴尔德和乌特霍夫。网球中变向速度评估和测试程序：系统综述。J 力量与体能研究 37(9)：1888-1895，2023 年-变向速度（CODS）在网球比赛中起着至关重要的作用，因此，CODS 表现通常在网球运动员中进行评估和监测。因此，本系统综述的目的是描述用于评估网球运动员 CODS 的测试的测试特征、性能指标、测试-重测可靠性、结构有效性和测试结果。在 PubMed 和 SPORTDiscus 上进行的文献检索产生了 563 个结果。在应用入选标准后，共有 27 项研究被纳入本综述。确定了 10 种独特的 CODS 测试。所有研究中最常使用的是 505 种测试变体，完成测试所需的总时间是研究最多的主要性能指标。日内测试-重测可靠性范围从“中等”到“优秀”。由于研究对象的人口统计学特征和研究这些方面的研究数量有限，日内和日间测试-重测可靠性以及网球表现、性别和年龄对 CODS 表现的影响尚不清楚。总之，大多数纳入的研究包括 CODS 测试，这些测试在 COD 进入和总距离方面表现出更长的距离，但在 COD 角度上与网球比赛中看到的相似。所有 CODS 测试的日内测试-重测可靠性至少为“中等”。然而，为了改进 CODS 评估方法，提高我们对网球运动员 CODS 表现的现有认识，需要对日间测试-重测可靠性、结构有效性以及性别、年龄和网球表现的影响进行更多研究，并研究其他可能提供 CODS 额外见解的性能指标（例如，特定阶段的性能变量）。
