A limitation of most rugby league time-motion studies is that researchers have examined the demands of single teams, with no investigations of all teams in an entire competition. This study investigated the activity profiles and technical and tactical performances of successful and less-successful teams throughout an entire rugby league competition.
In total, 185 rugby league players representing 11 teams from a semiprofessional competition participated in this study. Global positioning system analysis was completed across the entire season. Video footage from individual matches was also coded via notational analysis for technical and tactical performance of teams.
Trivial to small differences were found among Top 4, Middle 4, and Bottom 4 teams for absolute and relative total distances covered and distances covered at low speeds. Small, nonsignificant differences (P = .054, ES = 0.31) were found between groups for the distance covered sprinting, with Top 4 teams covering greater sprinting distances than Bottom 4 teams. Top 4 teams made more meters in attack and conceded fewer meters in defense than Bottom 4 teams. Bottom 4 teams had a greater percentage of slow play-the-balls in defense than Top 4 teams (74.8% ± 7.3% vs 67.2% ± 8.3%). Middle 4 teams showed the greatest reduction in high-speed running from the first to the second half (-20.4%), while Bottom 4 teams completed 14.3% more high-speed running in the second half than in the first half.
These findings demonstrate that a combination of activity profiles and technical and tactical performance are associated with playing success in semiprofessional rugby league players.
大多数橄榄球联盟时间动作研究的一个局限性是,研究人员仅检查了单个团队的需求,而没有对整个比赛中的所有团队进行调查。本研究调查了整个橄榄球联盟比赛中成功和不太成功的团队的活动概况以及技术和战术表现。
共有来自半职业比赛的 11 支球队的 185 名橄榄球联盟球员参加了这项研究。在整个赛季中完成了全球定位系统分析。还通过记分项对来自各个比赛的视频片段进行了编码,以分析团队的技术和战术表现。
在绝对和相对总距离以及低速距离方面,前 4 名、中 4 名和后 4 名球队之间的差异微不足道。在冲刺距离方面,各组之间的差异较小且无统计学意义(P =.054,ES = 0.31),前 4 名球队的冲刺距离大于后 4 名球队。前 4 名球队在进攻中行进的米数更多,在防守中放弃的米数更少。后 4 名球队在防守中的慢传次数占比高于前 4 名球队(74.8%±7.3%比 67.2%±8.3%)。中 4 队在上下半场之间的高速跑动减少量最大(-20.4%),而后 4 队在下半场的高速跑动比上半场多 14.3%。
这些发现表明,活动概况和技术与战术表现的结合与半职业橄榄球联盟球员的比赛成功有关。
