Describe the highest frequency and variability for tackle events in rugby league. Investigate seasonal differences in total tackle events per match over a seven-year period.
Retrospective observational.
Tackle events (i.e., ball carrier events [attacker] and tackler involvements [defender]) from 864 male professional rugby league players competing in 1176 Super League matches from 2014 to 2020 were included. A series of linear mixed effect models were used to determine the frequency and variability during peak 1-, 3-, 5-, 10-, 20-, 40-min and whole-match tackle events per player per match at a positional group level. Differences between seasons for the total number of tackle events per match were compared using a one-way analysis of variance and with Tukey's honestly significant difference test.
Tackle events were greatest for Props (51.5 [47.7-55.4] per match). Within-players, between-matches, and between-seasons variability was <10 % for tackle events. There were significantly less tackle events and tackler involvements per match in 2014 and a significantly more tackle events per match in season 2020 when compared with all other seasons.
Large between-position variability in peak tackle events, ball carrier events, and tackler involvements would suggest that coaches should separate players into positional groups and prescribe training accordingly. Total number of tackle events, ball carrier events, and tackler involvements were significantly greater in season 2020 when compared to season 2014 to 2019 (inclusive) which may be a consequence of rule changes introduced to the sport.
描述英式橄榄球联赛中擒抱事件的最高频率和变化。研究七个赛季中每场比赛总擒抱次数的季节性差异。
回顾性观察。
包括 2014 年至 2020 年间参加 1176 场超级联赛的 864 名男性职业英式橄榄球联赛球员的擒抱事件（即球传手事件[进攻者]和擒抱者参与[防守者]）。使用一系列线性混合效应模型，确定每个球员每场比赛在高峰 1、3、5、10、20、40 分钟和整个比赛期间的擒抱次数的频率和变化，按位置组水平进行分析。使用单向方差分析比较每个赛季每场比赛总擒抱次数的差异，并使用 Tukey 的诚实显着差异检验进行比较。
前锋的擒抱事件最多（每场比赛 51.5[47.7-55.4]次）。在球员内部、比赛之间和赛季之间，擒抱事件的变异性<10%。与所有其他赛季相比，2014 年每场比赛的擒抱次数和擒抱者参与次数明显减少，2020 年每场比赛的擒抱次数明显增加。
在高峰擒抱次数、球传手事件和擒抱者参与方面，位置之间的变异性很大，这表明教练应该将球员分为位置组，并相应地规定训练。与 2014 年至 2019 年（包括 2019 年）的所有赛季相比，2020 年的总擒抱次数、球传手事件和擒抱者参与次数明显增加，这可能是该运动引入规则变化的结果。
