The objective of this scoping review is to assess Nordic Hamstring Exercise quality (ANHEQ) of assessments and interventions according to the ANHEQ rating scales and to present practical recommendations for the expedient design and reporting of future studies. A total of 71 Nordic Hamstring Exercise (NHE) assessments and 83 NHE interventions were selected from the data sources PubMed, Scopus, and SPORTDiscus. Research studies which were presented in peer-reviewed academic journals and implemented the NHE during laboratory-based assessments or multi-week interventions met the eligibility criteria. NHE assessments analyzed force (51%), muscle activation (41%), knee angle kinematics (38%), and bilateral symmetry (37%). NHE interventions lasted 4-8 weeks (56%) and implied an exercise volume of two sessions per week (66%) with two sets per session (41%) and ≥8 repetitions per set (39%). The total ANHEQ scores of the included NHE assessments and interventions were 5.0 ± 2.0 and 2.0 ± 2.0 (median ± interquartile range), respectively. The largest deficits became apparent for consequences of impaired technique (87% 0-point-scores for assessments) and kneeling height (94% 0-point-scores for interventions). The 0-point-scores were generally higher for interventions compared to assessments for rigid fixation (87% vs. 34%), knee position (83% vs. 48%), kneeling height (94% vs. 63%), and separate familiarization (75% vs. 61%). The single ANHEQ criteria, which received the highest score most frequently, were rigid fixation (66% of assessments) and compliance (33% of interventions). The quality of NHE assessments and interventions was generally 'below average' or rather 'poor'. Both NHE assessments and interventions suffered from imprecise reporting or lacking information regarding NHE execution modalities and subsequent analyses. Based on the findings, this scoping review aggregates practical guidelines how to improve the design and reporting of future NHE-related research.
本综述的目的是根据 ANHEQ 评级量表评估北欧腘绳肌运动（NHE）评估和干预的质量，并为未来研究的快速设计和报告提供实用建议。从 PubMed、Scopus 和 SPORTDiscus 等数据源中选择了总共 71 项 NHE 评估和 83 项 NHE 干预。符合资格标准的研究是在同行评议的学术期刊上发表的，并在实验室评估或多周干预期间实施了 NHE。NHE 评估分析了力量（51%）、肌肉激活（41%）、膝关节角度运动学（38%）和双侧对称性（37%）。NHE 干预持续 4-8 周（56%），每周进行两次运动（66%），每次运动两次（41%），每组至少 8 次（39%）。纳入的 NHE 评估和干预的总 ANHEQ 评分为 5.0±2.0 和 2.0±2.0（中位数±四分位距）。技术受损的后果（评估中 87%为 0 分）和跪地高度（干预中 94%为 0 分）的缺陷最为明显。0 分在干预中通常高于评估，原因是刚性固定（87%对 34%）、膝关节位置（83%对 48%）、跪地高度（94%对 63%）和单独的熟悉（75%对 61%）。最常获得最高分的单个 ANHEQ 标准是刚性固定（评估中的 66%）和顺应性（干预中的 33%）。NHE 评估和干预的质量普遍“低于平均水平”或“较差”。NHE 评估和干预都存在不精确的报告或缺乏关于 NHE 执行方式和后续分析的信息。基于这些发现，本综述汇总了如何改进未来与 NHE 相关的研究的设计和报告的实用指南。
