Understanding how strength profiles of footballers effect the extent or location of injury sustained is limited. The purpose of this study was to investigate the effect of eccentric hamstrings strength (EHS), on the resultant injury sustained, graded utilizing the British Athletic Muscle Injury Classification, diagnosed via MRI.
EHS of 95 professional footballers were assessed on match-day minus two (MD-2) and plus two (MD+2). Participants completed three maximal repetitions of the bilateral Nordic hamstring exercises. Metrics included Peak Force (PF), Peak Torque (PkT), Average Force (AvF), Average Torque (AvT), Maximum Impulse (MI), Impulse Symmetry (IS), PF symmetry (PFS), PkT symmetry (PkTS) and relative strength (RS). Profiles were identified in relation to the date the injury was sustained.
EHS across all metrics with the exemption of PkT, had no effect on injury grade, site or playing level. Tendon injuries were the most frequently occurring injury location, specifically grade 3c. Athlete strength had no effect on whether an injury was sustained or grade of injury.
The occurrence of tendon related injury is high within this study population and may be a result of the physical strength of the muscle tissue, combined with game play demands, exposing the tendon to greater forces, thus heightening the extent of injury sustained. Level of Evidence - 3.
了解足球运动员的力量状况如何影响受伤的程度或部位的研究有限。本研究的目的是调查利用英国田径肌肉损伤分类法进行分级、通过磁共振成像（MRI）诊断的离心性腘绳肌力量（EHS）对所遭受的最终损伤的影响。
在比赛日前两天（MD - 2）和比赛日后两天（MD + 2）对95名职业足球运动员的EHS进行评估。参与者完成了双侧北欧式腘绳肌练习的三次最大重复动作。测量指标包括峰值力（PF）、峰值扭矩（PkT）、平均力（AvF）、平均扭矩（AvT）、最大冲量（MI）、冲量对称性（IS）、PF对称性（PFS）、PkT对称性（PkTS）和相对力量（RS）。根据受伤日期确定力量状况。
除PkT外，所有指标的EHS对损伤等级、部位或比赛水平均无影响。肌腱损伤是最常发生的损伤部位，特别是3c级。运动员的力量对是否受伤或损伤等级没有影响。
在本研究人群中，肌腱相关损伤的发生率较高，这可能是肌肉组织的体力与比赛需求相结合，使肌腱承受更大力量，从而增加了受伤程度的结果。证据等级 - 3。
