摘要

擒抱比赛是橄榄球比赛中最常见、伤害最大的比赛接触项目,也是衡量比赛成绩的一项指标。Tackle Ready 是世界橄榄球协会的擒抱技术教育计划。对女子橄榄球擒抱比赛特点的研究有限。本研究的目的是:(1) 确定精英女子橄榄球联盟中的比赛情况特征、持球人和擒抱人的技术动作,(2) 确定 Tackle Ready 推荐的擒抱技术的表现程度。根据预定义的编码框架和 Tackle Ready 计划,对 2022-2023 年女子六国锦标赛中 1500 次擒抱的技术特征进行了目测评估。擒抱动作没有完全完成(0.2%)22 项编码的 "擒抱就绪 "技术,平均每个擒抱动作展示了 47% 的推荐技术(范围在 15%-98% 之间)。较高比例的擒抱涉及两名防守者(48%)、从侧面(38%)或斜角(39%)接近持球者、采取直立姿势(30%)以及用手臂进行初步接触(51%)。在每场比赛中,擒抱者的头部和颈部平均有 14 次(95% CI 11-18 次)与持球者的头部和颈部接触,而持球者的头部和颈部平均有 18 次(95% CI 14-22 次)与擒抱者的头部和颈部接触。需要采取有针对性的干预措施,鼓励采用推荐的技术,以降低女子橄榄球比赛中与擒抱相关的受伤风险。这项研究为今后讨论女子橄榄球比赛中的执法、教练教育和针对不同性别的擒抱教练提供了宝贵的背景资料。

Are we tackle ready? Cross-sectional video analysis of match tackle characteristics in elite women's Rugby Union

The tackle contest is the most common and most injurious match contact event in rugby and is an indicator of performance. Tackle Ready is World Rugby's tackle technique education program. Limited research has characterized the tackle contest in women's rugby. The purpose of this study is to: (1) identify the match situational characteristics, ball-carrier and tackler technical actions demonstrated in elite women's Rugby Union and (2) to determine the extent to which Tackle Ready recommended tackle techniques were exhibited. Technical characteristics for 1500 tackle events in the 2022–2023 Women's Six Nations Championship were visually assessed according to a predefined coding framework and the Tackle Ready program. Tackles lacked full completion (0.2%) of the 22 coded Tackle Ready techniques with 47% of the recommended techniques demonstrated in each tackle on average (range 15%–98%). A high proportion of tackles involved two defenders (48%), approaching ball-carriers from the side (38%) or oblique angles (39%), in an upright position (30%), and with initial contact made with the arm (51%). Incorrect pre-contact head positioning and head placement upon contact accounted for 50% and 15% of tackles, respectively, and there was a mean of 14 (95% CI 11–18) head and neck contacts to a tackler and 18 (95% CI 14–22) head and neck contacts to a ball-carrier per game. Targeted interventions to encourage adoption of recommended techniques are needed to reduce tackle-related injury risk in women's rugby. This study provides valuable context for future discussion across law enforcement, coach education and gender-specific tackle coaching in the women's game.
