It is necessary to study the rugby tackle as it is associated with successful performance outcomes and is responsible for the majority of contact injuries. A novel collision sport simulator was developed to study tackle performance. The main aim of this validation study was to assess tackle technique performance between two different conditions: simulator versus a standardised one-on-one tackle drill previously used to assess technique. Tackling proficiency was assessed using a list of technical criteria. Mean scores, standard deviations and Cohen's d effect sizes were calculated. Mean overall score for dynamic i.e. running simulator tackles was 7.78 (95%CI 7.58-7.99) (out of 9) or 87% (standard deviation or SD±8.94), and mean overall score for dynamic "live" tackles was 7.85 (95%CI 7.57-8.13) (out of 9) or 87% (SD±9.60) (effect size = 0.08; trivial; p > 0.05). Mean overall score for static i.e. standing simulator tackles was 7.45 (95%CI 7.20-7.69) (out of 9) or 83% (SD±10.71), and mean overall score for static "live" tackles was 8.05 (95%CI 7.83-8.27) (out of 9) or 89% (SD±7.53) (effect size = 0.72; moderate; p < 0.001). The simulator replicates dynamic tackle technique comparable to real-life tackle drills. It may be used for research analysing various aspects of the tackle in rugby and other contact sports.
有必要对橄榄球擒抱进行研究,因为它与成功的表现结果相关,并且是造成大多数接触性损伤的原因。一种新型的碰撞运动模拟器被开发出来,用于研究擒抱表现。本验证研究的主要目的是评估两种不同条件下的擒抱技术表现:模拟器与之前用于评估技术的标准化一对一擒抱训练。使用一系列技术标准来评估擒抱熟练程度。计算了平均分数、标准差和 Cohen's d 效应量。动态即跑动模拟器擒抱的总体平均得分为 7.78(95%置信区间 7.58-7.99)(满分 9 分)或 87%(标准偏差或 SD±8.94),动态“现场”擒抱的总体平均得分为 7.85(95%置信区间 7.57-8.13)(满分 9 分)或 87%(SD±9.60)(效应量=0.08;微小;p>0.05)。静态即站立模拟器擒抱的总体平均得分为 7.45(95%置信区间 7.20-7.69)(满分 9 分)或 83%(SD±10.71),静态“现场”擒抱的总体平均得分为 8.05(95%置信区间 7.83-8.27)(满分 9 分)或 89%(SD±7.53)(效应量=0.72;中等;p<0.001)。模拟器复制了与现实生活中擒抱训练相当的动态擒抱技术。它可用于研究橄榄球和其他接触性运动中各种方面的擒抱技术。
