背景肌肉损伤和力量障碍之间的关系仍然存在争议。目的：职业足球运动员进行季前等速测试，以确定(1)力量变量是否可以预测随后的肌腱拉伤；(2)力量不平衡的正常化是否可以减少腿筋损伤的发生率。研究设计队列研究(预后)；证据水平，1。方法采用标准化的向心性和偏心性等速评价来识别力量失衡的足球运动员。根据不平衡管理内容将受试者分为4个子集。记录随后的腿部肌腱损伤使我们能够确定损伤频率和组间的相对风险。结果季前赛对687名运动员进行等速测试，462名运动员获得完全随诊，其中35人有肌腱损伤记录。与季前赛中没有表现出力量失衡的球员相比，未经治疗的力量失衡的受试者肌肉损伤的发生率显著增加(相对风险=4.66；95%可信区间：2.01-10.8)。有力量不平衡的运动员在随后进行了补偿训练，但没有进行最后的等速控制测试，受伤的风险仍然显著高于没有力量不平衡的球员(相对风险=2.89；95%可信区间：1.00-8.32)。相反，等速参数的正常化降低了受伤的风险因素，与没有失衡的球员相比(相对风险=1.43；95%可信区间：0.44-4.71)。结论等速训练能在季前赛中发现力量失衡，这是增加肌腱损伤风险的一个因素。恢复正常的力量轮廓可以减少肌肉损伤的发生率。
Background The relationship between muscle injury and strength disorders remains a matter of controversy. Purpose Professional soccer players performed a preseason isokinetic testing aimed at determining whether (1) strength variables could be predictors of subsequent hamstring strain and (2) normalization of strength imbalances could reduce the incidence of hamstring injury. Study Design Cohort study (prognosis); Level of evidence, 1. Methods A standardized concentric and eccentric isokinetic assessment was used to identify soccer players with strength imbalances. Subjects were classified among 4 subsets according to the imbalance management content. Recording subsequent hamstring injuries allowed us to define injury frequencies and relative risks between groups. Results Of 687 players isokinetically tested in preseason, a complete follow-up was obtained in 462 players, for whom 35 hamstring injuries were recorded. The rate of muscle injury was significantly increased in subjects with untreated strength imbalances in comparison with players showing no imbalance in preseason (relative risk = 4.66; 95% confidence interval: 2.01-10.8). The risk of injury remained significantly higher in players with strength imbalances who had subsequent compensating training but no final isokinetic control test than in players without imbalances (relative risk = 2.89; 95% confidence interval: 1.00-8.32). Conversely, normalizing the isokinetic parameters reduced the risk factor for injury to that observed in players without imbalances (relative risk = 1.43; 95% confidence interval: 0.44-4.71). Conclusion The outcomes showed that isokinetic intervention gives rise to the preseason detection of strength imbalances, a factor that increases the risk of hamstring injury. Restoring a normal strength profile decreases the muscle injury incidence.
