The purpose of this study was to determine the inter- and intra-testing reliability of newly developed tests of the change of direction speed (CODS) and reactive agility (RAG) in competitive futsal players. Additionally, the developed tests were evaluated for their validity with regard to the differentiation of two performance-levels. Thirty-two professional male futsal players (age = 26.22 ± 5.22 years; body height = 182.13 ± 5.99 cm, body mass = 77.43 ± 8.00 kg) participated in the study. The sample was divided into two groups based on their level of futsal performance: A top-level-group ( = 12) and a team-level-group ( = 20). The variables included body height, mass, body mass index, a sprint over a 10-m distance (S10M), and eight newly developed futsal specific CODS and RAG tests. The CODS and RAG tests were performed by dribbling the balls (CODS_D and RAG_D) and without dribbling (CODS_T and RAG_T), and the performances on the dominant and non-dominant sides were observed separately. All CODS, and RAG tests performed on dominant side and RAG_T tests performed on the non-dominant side had good inter-testing (CV = 5-8%; ICC = 0.76-0.89) and intra-testing (CV = 4-9%; ICC = 0.77-0.91) reliability. However, RAG_D performed on the non-dominant side was not reliable (ICC = 0.60, CV = 10%). The top-level-players outperformed the team-level-players in the CODS and RAG tests that involved dribbling (-test: 4.28 and 2.40, < 0.05; effect sizes (ES): 0.81 and 1.5, respectively), while the team-level players achieved better results in the CODS_T (-test: 2.08, < 0.05; ES: 0.60). The proposed CODS and RAG tests that involved dribbling over a 3.2-m distance, especially on the dominant side, appeared to be reliable, as well as valid for distinguishing the performance level in futsal players.
本研究旨在确定新开发的足球变向速度（CODS）和反应敏捷性（RAG）测试在竞技五人制足球运动员中的测试内和测试间可靠性。此外，还评估了这些新开发的测试在区分两个表现水平方面的有效性。32 名专业男性五人制足球运动员（年龄=26.22±5.22 岁；身高=182.13±5.99cm，体重=77.43±8.00kg）参加了这项研究。根据他们的五人制足球表现水平，样本被分为两组：高水平组（n=12）和团队水平组（n=20）。变量包括身高、体重、体重指数、10 米冲刺（S10M）和八项新开发的足球专项 CODS 和 RAG 测试。CODS 和 RAG 测试分别通过带球（CODS_D 和 RAG_D）和不带球（CODS_T 和 RAG_T）进行，并且分别观察优势侧和非优势侧的表现。所有在优势侧进行的 CODS 和 RAG 测试以及在非优势侧进行的 RAG_T 测试都具有良好的测试内（CV=5-8%；ICC=0.76-0.89）和测试间（CV=4-9%；ICC=0.77-0.91）可靠性。然而，在非优势侧进行的 RAG_D 测试不可靠（ICC=0.60，CV=10%）。高水平运动员在涉及带球的 CODS 和 RAG 测试中表现优于团队水平运动员（-检验：4.28 和 2.40，<0.05；效应大小（ES）：0.81 和 1.5，分别），而团队水平运动员在 CODS_T 测试中表现更好（-检验：2.08，<0.05；ES：0.60）。涉及带球越过 3.2 米距离的新开发的 CODS 和 RAG 测试，特别是在优势侧，似乎是可靠的，并且能够有效区分五人制足球运动员的表现水平。
