Abstract

Nordic hamstring curls (NHC) are a commonly used injury intervention method in amateur team sports. Seventeen elite male academy soccer players performed an 8-week low volume NHC programme. Pre-post intervention measures of isokinetic eccentric knee flexor (KF) strength, linear speed, COD performance, hamstring muscle thickness, pennation angle and fascicle length were recorded. No significant main effects were observed for measures of isokinetic KF strength (P ≥ 0.19), linear sprint speed (P ≥ 0.47) or hamstring muscle architecture (P ≥ 0.30). However, significance was noted for improved COD performance (P < 0.01; mean difference, -0.06, p = 0.001, 95% CI = 0.03 to 0.09; d = 0.80), exceeding the minimal detectable difference (MDD = 0.05 s). A low-volume NHC intervention may contribute to significant improvements in COD ability, independent of no significant changes in eccentric KF strength, linear sprint speed or muscle architectural properties in elite youth soccer players.

尽管青少年精英足球运动员在建筑、力量或速度方面没有适应性，但低强度北欧式腿筋卷曲训练却能提高他们的变向能力。

北欧式腿筋卷曲（NHC）是业余团队运动中常用的损伤干预方法。17 名精英男子足球运动员参加了为期 8 周的低运动量 NHC 项目。记录了干预前和干预后的等速偏心屈膝（KF）力量、线性速度、COD表现、腘绳肌厚度、五点角和筋膜长度。等动偏心屈膝力量（P≥0.19）、直线冲刺速度（P≥0.47）或腘绳肌结构（P≥0.30）的测量结果均未观察到明显的主效应。不过，COD 性能的改善具有显著性（P d = 0.80），超过了最小可检测差异（MDD = 0.05 s）。在青少年精英足球运动员的偏心 KF 力量、线性冲刺速度或肌肉结构特性没有显著变化的情况下，低容量 NHC 干预可能有助于显著提高 COD 能力。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
