Rugby league is a collision sport where musculoskeletal injuries are common. There has been little research on generalised joint hypermobility (GJH) as a risk factor for injury in rugby league. The aim of this study was to investigate the role of GJH on the incidence of injuries in first and second team rugby league players from one British university.
We conducted a prospective cohort study of 45 student players from one British university first and second team rugby league squads (mean age 20.93±1.57 years). At the beginning of the season, GJH was determined using a 9-point Beighton scale, and injury and exposure data were collected on a weekly basis throughout the 2013-2014 season.
The prevalence of GJH was 20%. There was no statistically significant difference in the frequency of injuries between GJH and non-GJH participants (p=0.938, Mann-Whitney U test).Participants categorised as having GJH did not experience a higher fequency of injury (p=0.722, Fisher's exact test) and there was no tendency to demonstrate a higher risk of injury for participants categorised as GJH (OR=0.64, 95% CI 0.15 to 2.78; relative risk (RR)=1.188, 95% CI 0.537 to 2.625). The most common site of injury was the ankle, but this was not statistically significant (OR=0.152, 95% CI 0.008 to 2.876; RR=0.195, CI 0.012 to 3.066).
British university rugby league players with GJH did not demonstrate a greater risk of injury than those without GJH.
英式橄榄球联盟是一项碰撞性运动，肌肉骨骼损伤很常见。关于广义关节过度活动（GJH）作为英式橄榄球联盟损伤风险因素的研究很少。本研究的目的是调查GJH在一所英国大学一线队和二线队英式橄榄球联盟球员损伤发生率中的作用。
我们对一所英国大学一线队和二线队英式橄榄球联盟45名学生球员（平均年龄20.93±1.57岁）进行了一项前瞻性队列研究。在赛季开始时，使用9分Beighton量表确定GJH，并在整个2013 - 2014赛季每周收集损伤和暴露数据。
GJH的患病率为20%。GJH参与者和非GJH参与者之间的损伤频率没有统计学显著差异（p = 0.938，Mann - Whitney U检验）。被归类为患有GJH的参与者没有经历更高的损伤频率（p = 0.722，Fisher精确检验），并且被归类为GJH的参与者没有表现出更高损伤风险的趋势（OR = 0.64，95% CI 0.15至2.78；相对风险（RR）= 1.188，95% CI 0.537至2.625）。最常见的损伤部位是脚踝，但这在统计学上不显著（OR = 0.152，95% CI 0.008至2.876；RR = 0.195，CI 0.012至3.066）。
患有GJH的英国大学英式橄榄球联盟球员与没有GJH的球员相比，没有表现出更大的损伤风险。
