Previous studies showed that the Nordic hamstring exercise (NHE) effectively prevents primary hamstring injury. However, no study investigated the secondary preventing effect of the NHE on hamstring reinjury. The primary purpose of this study is to investigate the effectiveness of the NHE for preventing hamstring reinjury after return to play (RTP) following a hamstring injury in football players. The secondary purpose is to determine the effect of the NHE on sprint and jump performance.
This is an international multicentre, prospective, parallel-group randomised controlled trial study. Subjects include male or female football players aged 18-40 years and within 1 week of RTP following a hamstring injury will be randomised into Nordics or a control group. Subjects in both groups continue their regular football training, but the Nordics group will perform an additional NHE programme. An online questionnaire will be sent to the subjects in both groups once per week within the first 10 weeks, then continued at months 6, 9 and 12. In a (performance) substudy, we will evaluate the effect of the NHE on sprint and vertical jump performance at three time points (at the beginning of the study, after 10 weeks and 12 months of follow-up).The primary outcomes are the incidence of hamstring reinjury within 2 and 12 months. The secondary outcomes are sprint and jump performance, adherence to the programme, duration of reinjury and reinjury burden.
This study is approved by the medical ethics committee of Amsterdam University Medical Center (UMC) in the Netherlands (METC 2021_117), Faculty of Medicine Universitas Gadjah Mada in Indonesia (KE/FK/1248/EC/2021), Norwegian School of Sport Sciences in Norway (number 216-2 70 122) and Denmark (ethical submission in process). The study's findings will be disseminated in scientific peer-reviewed journals and presented at international conferences.

先前的研究表明，北欧腘绳肌训练（Nordic hamstring exercise，NHE）可有效预防原发性腘绳肌损伤。然而，尚无研究调查 NHE 对腘绳肌再损伤的二级预防作用。本研究的主要目的是调查 NHE 在足球运动员发生腘绳肌损伤后重返赛场（return to play，RTP）后对腘绳肌再损伤的预防效果。次要目的是确定 NHE 对冲刺和跳跃表现的影响。
这是一项国际性、多中心、前瞻性、平行组随机对照试验研究。研究对象包括年龄在 18-40 岁之间的男性或女性足球运动员，且在 RTP 后 1 周内发生腘绳肌损伤。这些受试者将被随机分为北欧组或对照组。两组受试者均继续接受常规足球训练，但北欧组将额外进行 NHE 方案。在最初的 10 周内，每周将向两组受试者发送一次在线问卷，之后在第 6、9 和 12 个月继续发送。在一项（表现）子研究中，我们将评估 NHE 对冲刺和垂直跳跃表现的影响，共评估三个时间点（研究开始时、10 周后和 12 个月随访时）。主要结局是 2 个月和 12 个月内腘绳肌再损伤的发生率。次要结局是冲刺和跳跃表现、对方案的依从性、损伤持续时间和损伤负担。
本研究已获得荷兰阿姆斯特丹大学医学中心（UMC）医学伦理委员会（METC 2021_117）、印度尼西亚加查马达大学医学院（KE/FK/1248/EC/2021）、挪威体育科学学院（号码 216-2 70 122）和丹麦（正在提交伦理申请）的批准。研究结果将在科学同行评议期刊上发表，并在国际会议上展示。
