Handball is one of the most traumatic sports. The knee is the most commonly injured joint. To prevent knee injuries, optimal functional knee stability is of great importance. Nevertheless, there is still no consensus about objective criteria for knee function. Depending on playing class, injury rates seem to differ. The purpose of this study was to evaluate knee function in handball depending on playing class and to establish reference data for functional knee stability. 261 handball players (25.1±5.8 years) performed a functional test including two- and one-legged stability assessments, jump tests, speed and agility analysis. Except for balance, differences between playing classes were detected in all tests with superior performance of high-class players (Germany's 1st ("Oberliga") and 2nd ("Verbandsliga") non-elite playing class). High-class players achieved significant better results in jumping height (p≤0.011-0.029), relative power per body weight in the two-legged counter movement jump (p≤0.023) and speed and agility tests (p≤0.001). This study illustrates the relevance of playing class specific screening. Sports and playing class-specific databases will help to identify individual deficits and strengths in order to prevent injury and increase performance. Moreover, objective criteria for return to sports can be established.
手球是最具创伤性的运动之一。膝关节是最常受伤的关节。为了预防膝关节损伤，膝关节的最佳功能稳定性非常重要。然而，对于膝关节功能的客观标准仍没有共识。根据比赛级别，受伤率似乎有所不同。本研究旨在根据比赛级别评估手球运动员的膝关节功能，并建立膝关节功能稳定性的参考数据。261 名手球运动员（25.1±5.8 岁）进行了一项功能测试，包括双腿和单腿稳定性评估、跳跃测试、速度和敏捷性分析。除了平衡测试外，所有测试的比赛级别之间都存在差异，高级别运动员（德国的 1 级（“Oberliga”）和 2 级（“Verbandsliga”）非精英比赛级别）表现更好。高级别运动员在跳跃高度（p≤0.011-0.029）、双腿反向运动跳跃的相对体重功率（p≤0.023）和速度敏捷性测试（p≤0.001）中取得了显著更好的成绩。本研究说明了根据比赛级别进行特定筛查的重要性。运动和比赛级别特定的数据库将有助于确定个体的缺陷和优势，以预防受伤和提高表现。此外，可以建立重返运动的客观标准。
