Calf muscle strain injuries (CMSI) show consistent rates of prevalence and re-injury in elite Australian Football players. An epidemiological evaluation is warranted to better understand the clinical presentation and recovery of CMSI.
First, to describe the epidemiology of CMSI in elite Australian Football players. Second, to determine if recovery following injury is different according to: (a) injury type (index vs re-injury); (b) muscle injured (soleus vs gastrocnemius); and (c) mechanism of injury (running-related activity vs non running-related activity).
Descriptive epidemiological.
Data retrieved from the Soft Tissue injury Registry of the Australian Football League were analyzed. Sixteen clubs submitted data on CMSI from 2014 to 2017. Data included: player characteristics, training and match history at the time of injury, MRI, and the time to reach recovery milestones.
One hundred and eighty-four CMSI were included (149 index injuries; 35 re-injuries). Soleus injuries were most prevalent (84.6%). Soleus injuries took 25.4 ± 16.2 days to return to play, whereas gastrocnemius injuries took 19.1 ± 14.1 days (P = .097). CMSI sustained during running-related activities took approximately 12 days longer to recover than injuries sustained during non running-related activities (P = .001). Compared to index injuries, re-injuries involved older players (P = .03) and significantly more time was taken to run at >90% of maximum speed, return to full training, and return to play (P ≤ .001). Almost all of the observed re-injuries involved soleus (91.4%).
Soleus injuries are more prevalent than gastrocnemius injuries in elite Australian Football players. Prognosis appears to be influenced by clinical factors, with CMSI sustained during running-related activities and re-injuries needing more time to recover.
小腿肌肉拉伤（CMSI）在澳大利亚精英足球运动员中始终保持着较高的发病率和再受伤率。为了更好地了解 CMSI 的临床表现和康复情况，有必要进行一项流行病学评估。
首先，描述澳大利亚精英足球运动员中 CMSI 的流行病学情况。其次，根据以下情况确定受伤后的恢复是否有所不同：（a）受伤类型（初次受伤与再受伤）；（b）受伤肌肉（比目鱼肌与腓肠肌）；（c）受伤机制（与跑步相关的活动与非跑步相关的活动）。
描述性流行病学研究。
对澳大利亚足球联赛软组织损伤登记处的数据进行了分析。2014 年至 2017 年期间，有 16 个俱乐部提交了 CMSI 数据。数据包括：受伤时的球员特征、训练和比赛情况、MRI 以及达到康复里程碑的时间。
共纳入 184 例 CMSI（149 例初次受伤；35 例再受伤）。比目鱼肌损伤最为常见（84.6%）。比目鱼肌损伤恢复到可参赛状态需要 25.4±16.2 天，而腓肠肌损伤则需要 19.1±14.1 天（P=0.097）。与非跑步相关的活动相比，与跑步相关的活动导致的 CMSI 恢复时间大约延长了 12 天（P=0.001）。与初次受伤相比，再受伤涉及的球员年龄更大（P=0.03），且需要更长的时间才能以超过 90%最大速度跑步、恢复全面训练和重返赛场（P≤0.001）。几乎所有观察到的再受伤都涉及比目鱼肌（91.4%）。
在澳大利亚精英足球运动员中，比目鱼肌损伤比腓肠肌损伤更为常见。预后似乎受到临床因素的影响，与跑步相关的活动和再受伤导致的 CMSI 需要更长的时间才能恢复。
