Brain health has been a growing concern across a wide range of contact sports in the last three decades. While most of the early brain health research was focused on identifying and preventing concussions, newer research has found that an accumulation of repetitive head impacts (RHI) are more predictive of long-term brain health than the number of concussions sustained. Consequently, being able to assess RHI in sports despite the lack of outward symptoms has become paramount in promoting the long-term health of athletes. The sport of rodeo has long been regarded as one of the most dangerous contact sports. While some epidemiological research has been done on injury rates in rodeo that has largely backed up its dangerous reputation, no research has been done into RHI in rodeo athletes.
Head acceleration events (HAE) were measured in collegiate athletes competing in the "Roughstock" events of Bareback Riding, Saddle Bronc Riding and Bull Riding. HAE were recorded using impact monitoring mouthgaurds (iMG) and subsequently confirmed using video verification and submitted to statistical analysis.
Rodeo has a high rate of HAE across all the Roughstock events. The Bull Riding experiences the highest magnitude HAE based on both linear and rotational acceleration. These events are primarily the result of the head impacting either the ground or the animal during the dismount phase of the ride. Bareback riding experiences the highest quantity of lower magnitude HAE which mainly result from whiplash-like movement of the head during the ride.
Rodeo athletes experience a high volume of HAE that often reach concerning magnitude. A surprising amount of the HAE are the result not of impacts, but of the whiplash-like movement that is experienced during the rides.
在过去的三十年中,大脑健康已成为各种接触性运动关注的焦点。虽然早期的大多数大脑健康研究都集中在识别和预防脑震荡上,但新的研究发现,重复性头部冲击(RHI)的积累比脑震荡的次数更能预测大脑的长期健康。因此,尽管缺乏外在症状,能够在运动中评估 RHI 对于促进运动员的长期健康变得至关重要。牛仔竞技运动长期以来一直被认为是最危险的接触性运动之一。虽然已经对牛仔竞技运动中的受伤率进行了一些流行病学研究,这些研究在很大程度上证实了其危险的声誉,但尚未对牛仔竞技运动员的 RHI 进行研究。
使用冲击监测口套(iMG)测量参加无鞍骑术、鞍马骑术和公牛骑术“ Roughstock”赛事的大学生运动员的头部加速度事件(HAE)。HAE 是通过视频验证和提交给统计分析来记录和确认的。
牛仔竞技运动中所有“ Roughstock”赛事的 HAE 发生率都很高。根据线性和旋转加速度,公牛骑术的 HAE 幅度最大。这些事件主要是由于在骑乘的下马阶段头部撞击地面或动物造成的。无鞍骑术的低幅度 HAE 数量最高,主要是由于骑乘过程中头部的鞭打样运动造成的。
牛仔竞技运动员经历了大量的 HAE,这些 HAE 的幅度通常令人担忧。令人惊讶的是,相当一部分 HAE 不是由于撞击造成的,而是由于骑乘过程中头部的鞭打样运动造成的。
