BACKGROUND
Copenhagen adduction exercise (CAE) and Nordic hamstring exercise (NHE) reduce the incidence of groin and hamstring injuries. Efficient dynamic balance can improve motor performance and reduce the risk of injuries in athletes. However, the effects of these exercises on dynamic balance have not been investigated.
HYPOTHESIS
CAE and NHE, as well as a combination of both exercises, would improve dynamic balance among amateur male athletes.
STUDY DESIGN
Randomized controlled trial.
LEVEL OF EVIDENCE
Level 1.
METHODS
A total of 200 male athletes aged 21.9 ± 2.4 years were included in the study and randomly assigned to 4 groups: CAE group (n = 50), NHE group (n = 50), CAE and NHE group (n = 50), and a control group (n = 50). A total of 177 male athletes completed the study. The primary outcome measure was the limit of stability (LoS), which was measured using the Biodex Stability System to assess the performance of the dynamic balance. The LoS of the athletes' performance was measured pre- and postintervention after 6 weeks.
RESULTS
The LoS significantly improved in all treatment groups, including CAE (44.5% ± 5.3%), NHE (43.2% ± 5.3%), and CAE + NHE (48.4% ± 5.1%) groups when compared with the control group (28.3% ± 4.8%) after 6 weeks (all s < 0.01). The improvement of LoS was significantly greater in the CAE + NHE group compared with other groups (CAE, NHE, and control groups).
CONCLUSION
There was a significant increase in dynamic balance performance postintervention among male athletes. CAE and NHE may improve injury prevention programs.
CLINICAL RELEVANCE
The results of this study provide evidence for athlete trainers and coaches to consider including the CAE and NHE as components of injury prevention programs to improve balance capacity and performance in athletes. Such improvements in balance may prevent injury risk and decrease absenteeism and injury-related financial burdens.
背景
哥本哈根内收肌锻炼（CAE）和北欧绳肌锻炼（NHE）可降低腹股沟和绳肌损伤的发生率。有效的动态平衡可改善运动表现并降低运动员受伤风险。然而，这些锻炼对动态平衡的影响尚未得到研究。
假设
CAE、NHE以及两者相结合的锻炼方式，将改善男性业余运动员的动态平衡。
研究设计
随机对照试验。
证据等级
1级。
方法
共有200名年龄在21.9±2.4岁的男性运动员纳入本研究，并随机分为4组：CAE组（n = 50）、NHE组（n = 50）、CAE与NHE联合组（n = 50）和对照组（n = 50）。共有177名男性运动员完成了研究。主要观察指标是稳定性极限（LoS），使用Biodex稳定性系统进行测量以评估动态平衡表现。在干预前后6周测量运动员表现的LoS。
结果
与对照组（28.3%±4.8%）相比，6周后所有治疗组的LoS均显著改善，包括CAE组（44.5%±5.3%）、NHE组（43.2%±5.3%）和CAE + NHE组（48.4%±5.1%）（所有P<0.01）。与其他组（CAE组、NHE组和对照组）相比，CAE + NHE组LoS的改善显著更大。
结论
男性运动员干预后动态平衡表现有显著提高。CAE和NHE可能改善损伤预防方案。
临床意义
本研究结果为运动员训练师和教练提供了证据，使其考虑将CAE和NHE纳入损伤预防方案的组成部分，以提高运动员的平衡能力和表现。这种平衡能力的提高可能预防受伤风险，并减少缺勤率和与损伤相关的经济负担。
