Abstract

BACKGROUND: Test selection during the return to sport evaluation is an important aspect of ensuring athletes are safe to return to competition. OBJECTIVE: To assess the test-retest and inter-rater reliability of two new single leg hamstring bridge tests (SLHBT) and the relationships between these new tests and isokinetic strength of the quadriceps and hamstrings. METHODS: Thirty healthy college students completed the study. Two testing sessions were held three to seven days apart. Session one, participants performed two SLHBT as well as concentric isokinetic strength tests for the hamstring and quadriceps at 60, 180 and 300∘/sec. The participants performed only the two SLHBT during the second session. The first SLHBT, participants performed as many repetitions as possible of the SLHBT in 30-sec, while the second test measured how quickly the participants could perform five repetitions. Intraclass Correlation Coefficients (ICC2,1) were used to assess test-retest reliability while ICC(3,1) were used to test inter-rater reliability. RESULTS: The test-retest reliability for the SLHBTs was moderate to good, with ICC(2,1) ranging from 0.68 to 0.75, while the inter-rater reliability were excellent with ICC(3,1) all above 0.98. There were significant correlations between the SLHBT and the isokinetic tests, but all correlations were low to moderate. CONCLUSION: This study found good to excellent reliability with the new SLHBT and poor to moderate correlations were noted Therefore, SLHBT may not be an alternative to test hamstring test during the RTS evaluation due to the multiple compensatory strategies athletes may have.

两种新的单腿腿筋桥接试验的可靠性以及与等速力量试验的比较

背景：重返运动评估中的测试选择是确保运动员安全重返赛场的一个重要方面。目的：评估两种新的单腿腘绳肌桥接试验（SLHBT）的重复测试和评分者之间的可靠性，以及这些新试验与股四头肌和腘绳肌等动力量之间的关系。方法：30 名健康的大学生完成了这项研究。两次测试相隔三到七天。第一节，参与者进行了两次 SLHBT 以及 60、180 和 300∘/秒的腘绳肌和股四头肌同心等动力量测试。在第二个环节中，参与者只进行了两项 SLHBT。在第一项 SLHBT 测试中，参与者在 30 秒内尽可能多地重复做 SLHBT，而第二项测试则测量参与者做五次重复的速度。类内相关系数（ICC2,1）用于评估测试-重复测试的可靠性，而 ICC(3,1) 则用于测试评分者之间的可靠性。结果：SLHBT 的重测信度为中等至良好，ICC(2,1) 在 0.68 至 0.75 之间，而评分者之间的信度则非常好，ICC(3,1) 均在 0.98 以上。SLHBT 与等速肌力测试之间存在明显的相关性，但所有相关性均为低度至中度。结论：本研究发现，新的 SLHBT 具有良好至卓越的可靠性，但相关性较差至中等。

期刊介绍： Isokinetics and Exercise Science (IES) is an international journal devoted to the study of theoretical and applied aspects of human muscle performance. Since isokinetic dynamometry constitutes the major tool in this area, the journal takes a particular interest in exploring the considerable potential of this technology. IES publishes studies associated with the methodology of muscle performance especially with respect to the issues of reproducibility and validity of testing, description of normal and pathological mechanical parameters which are derivable from muscle testing, applications in basic research topics such as motor learning paradigms and electromyography. The journal also publishes studies on applications in clinical settings and technical aspects of the various measurement systems employed in human muscle performance research. The journal welcomes submissions in the form of research papers, reviews, case studies and technical reports from professionals in the fields of sports medicine, orthopaedic and neurological rehabilitation and exercise physiology.
