In collision sports, the tackle has the highest injury incidence, and is key to a successful performance. Although the contact load of players has been measured using microtechnology, this has not been related to tackle technique. The aim of this study was to explore how changes between different levels of tackling technique during a simulated tackle. Nineteen rugby union players performed twelve tackles on a tackle contact simulator (n = 228 tackles). Each tackle was recorded with a video-camera and each player wore a Catapult OptimEyeS5. Tackles were analysed using tackler proficiency criteria and split into three categories: Low scoring(≤5 Arbitrary units (AU), medium scoring(6 and 7AU) and high scoring tackles(≥8AU). High scoring tackles recorded a higher at tackle completion. The trace was also less variable in the high scoring tackles. The variability in the trace may be a consequence of players not shortening their steps before contact. This reduced their ability to control their movement during the contact and post-contact phase of the tackle and increased the variability. Using the trace in conjunction with subjective technique assessments offers coaches and practitioners insight into the physical-technical relationship of each tackle to optimise tackle skill training and match preparation.
在碰撞性运动中，擒抱的受伤发生率最高，是取得成功的关键。虽然已经使用微技术测量了运动员的接触负荷，但尚未将其与擒抱技术联系起来。本研究旨在探讨在模拟擒抱中，不同擒抱技术水平之间的变化。19 名橄榄球运动员在擒抱接触模拟器上进行了 12 次擒抱（228 次擒抱）。每次擒抱都用摄像机记录下来，每个运动员都戴着 Catapult OptimEyeS5。擒抱分析使用擒抱者熟练标准，分为三个类别：低得分（≤5 个任意单位 (AU)）、中得分（6 和 7AU）和高得分（≥8AU）。高得分的擒抱在完成时的 更高。高得分的擒抱中， 的轨迹也更稳定。轨迹的可变性可能是由于运动员在接触前没有缩短步幅。这降低了他们在接触和接触后阶段控制自己运动的能力，并增加了可变性。结合主观技术评估使用 轨迹，可以为教练和从业人员提供有关每次擒抱的物理技术关系的深入了解，从而优化擒抱技能训练和比赛准备。
