The aim of this pilot study was to analyze the potential financial loss and a range of potential risk factors for hamstring muscle injuries in elite Brazilian soccer.
Thirty-four male players (age: 25 ± 6 years; stature: 180 ± 8 cm; body mass: 78 ± 9 kg; minutes played in matches: 2243 ± 1423 min) from an elite professional soccer club were monitored during a 12-month season. Muscle injury was identified by magnetic resonance imaging and the severity was defined according to the number of days away: minimal (1-3 days), mild (4-7 days), moderate (8-28 days), severe (>28 days). Potential financial loss due to the team's under achievements was determined. Dorsiflexion range of motion, eccentric knee flexor strength and isokinetic tests were performed during the pre-season. Association between dependent variables and the occurrence of injury was evaluated.
Nine hamstring muscle injuries with moderate severity were found in 8 athletes. Recovery time was 22 days off the field on average. Potential financial loss was $-43.2 million USD and earnings on merit money was 21%. Previous injury, increased flexor deficit 60° /sec and increased flexor fatigue index 300°/sec were all associated with a greater chance of hamstring muscle injury. Ankle dorsiflexion range of motion was significantly lower in the injured group (35.6 ± 3° vs. 39.1 ± 4.9°; = 0.017, effect size = -0.74).
High financial burden was found in elite Brazilian soccer during one full season. Injured athletes had high hamstring fatigue index, knee flexor strength deficit, ankle range of motion restriction and previous hamstring muscle injury when compared to non-injured athletes. Therefore, preventive approaches in professional soccer players with previous hamstring injuries should be a priority.
本初步研究旨在分析巴西精英足球运动员腘绳肌损伤的潜在经济损失及一系列潜在风险因素。
在一个为期12个月的赛季中，对一家精英职业足球俱乐部的34名男性球员（年龄：25±6岁；身高：180±8厘米；体重：78±9千克；比赛上场时间：2243±1423分钟）进行监测。通过磁共振成像确定肌肉损伤情况，并根据缺阵天数定义损伤严重程度：轻微（1 - 3天）、轻度（4 - 7天）、中度（8 - 28天）、重度（>28天）。确定因球队成绩不佳造成的潜在经济损失。在赛季前进行背屈活动度、膝关节屈肌离心力量和等速测试。评估因变量与损伤发生之间的关联。
8名运动员发生了9例中度腘绳肌损伤。平均缺阵恢复时间为22天。潜在经济损失为4320万美元，奖金收入为21%。既往损伤、60°/秒时屈肌不足增加以及300°/秒时屈肌疲劳指数增加均与腘绳肌损伤几率增加相关。损伤组的踝关节背屈活动度显著更低（35.6±3°对39.1±4.9°；P = 0.017，效应量 = -0.74）。
在巴西精英足球一个完整赛季中发现了高额经济负担。与未受伤运动员相比，受伤运动员腘绳肌疲劳指数高、膝关节屈肌力量不足、踝关节活动度受限且有既往腘绳肌损伤史。因此，对于有既往腘绳肌损伤的职业足球运动员，预防措施应成为优先事项。
