The aim of this study was to analyse the relationship between unilateral leg strength, associated asymmetries and the injuries suffered by sub-elite Rugby League (RL) players in one competitive season.
A prospective cohort design was used.
Unilateral leg strength was measured using the rear foot elevated split squat five repetition maximum test. Injuries were recorded using the Orchard classification system and were used to quantify relative risk (RR), mean severity, burden, player availability and survival time.
No measures of leg strength were related to RR, relative leg strength was found to have a significant, but not meaningful correlation with total time lost to lower body injury, lower body injury burden and lower body injury survival time.
The data from the current study indicates a possible positive effect of increasing relative leg strength for injury outcomes in sub-elite RL players. This supports a heuristic that multi-joint lower body strength training for RL players has a potential dual effect of enhancing physical performance and reducing injury time loss, with minimal risk of harm.
本研究旨在分析单侧腿部力量、相关不对称性与一名精英级橄榄球联赛（RL）运动员在一个赛季中所受伤害之间的关系。
前瞻性队列设计。
使用后脚抬高分腿深蹲 5 次最大重复测试来测量单侧腿部力量。使用 Orchard 分类系统记录伤害，并用于量化相对风险（RR）、平均严重程度、负担、运动员可利用率和生存时间。
腿部力量的任何测量指标均与 RR 无关，相对腿部力量与下肢损伤总损失时间、下肢损伤负担和下肢损伤生存时间具有显著但无意义的相关性。
当前研究的数据表明，增加相对腿部力量可能对亚精英级 RL 运动员的伤害结果产生积极影响。这支持了一个假说，即 RL 运动员的多关节下肢力量训练具有增强身体表现和减少伤害损失时间的潜在双重效果，且伤害风险极小。
