Senior club-level rugby union player's positional movement performance using individualized velocity thresholds and accelerometer-derived impacts in matches. J Strength Cond Res 36(3): 710-716, 2022-Game demands of professional rugby union players have been well documented; however, there is minimal game demand information using individualized velocity thresholds and collision loads, particularly for amateurs. This study investigated movement patterns of 20 male amateur rugby players during 16 senior premier division one matches using global positioning system (GPS) devices sampling at 10 Hz. Derived GPS variables included distances, velocities, sprinting, and impacts. Data files from 86 player games (≥60 minutes of play per game) were categorized into broad (forwards and backs) and specific (front row, second row, back row, half back, inside back, and outside back) positional groups for analysis. It was most likely that backs covered more distance in the high-speed running (>60% maximal velocity) zone (502 ± 157 m) compared with forwards (238 ± 147 m) (100/0/0%, chances of positive/trivial/negative differences, effect size [ES] = 1.3), performed more striding (backs 1,116 ± 240, forwards 954 ± 240 m, 96/4/0%, ES = 0.5), and sprinting (backs 121 ± 58, forwards 90 ± 65 m, 93/7/0%, ES = 0.5). However, forwards had higher collision loads (35 ± 12 arbitrary units) compared with backs (20 ± 6, 99.9/0.1/0%, ES = 1.3) with back row forwards completing the highest collision load of any playing position (40 ± 13). Our example match movement performance and impact information is valuable to coaches and support staff in preparing player profiles for similar-level rugby players to help manage their workloads.
Takamori, S, Hamlin, MJ, Kieser, DC, King, D, Hume, P, Yamazaki, T, Hachiya, M, 和 Olsen, PD. 个体速度阈值和加速度计衍生冲击在比赛中对高级俱乐部级橄榄球联盟运动员位置移动表现的影响。J 力量与体能研究 36(3):710-716, 2022-职业橄榄球联盟运动员的比赛需求已经有充分的记录；然而，使用个体速度阈值和碰撞负荷的比赛需求信息很少，特别是对于业余运动员。本研究使用全球定位系统 (GPS) 设备以 10 Hz 的采样率对 20 名男性业余橄榄球运动员在 16 场高级一级联赛中的位置移动模式进行了 16 场比赛。衍生的 GPS 变量包括距离、速度、冲刺和冲击。来自 86 名球员比赛（每场比赛≥60 分钟）的数据文件根据广泛（前锋和后卫）和特定（前排、后排、后锋、半卫、内卫和外卫）位置组进行分类。与前锋相比，后卫在高速跑动（>60%最大速度）区域（502 ± 157 m）中更有可能覆盖更多的距离（100/0/0%，阳性/微不足道/阴性差异的可能性，效应大小[ES] = 1.3），完成更多的跨步（后卫 1,116 ± 240，前锋 954 ± 240 m，96/4/0%，ES = 0.5）和冲刺（后卫 121 ± 58，前锋 90 ± 65 m，93/7/0%，ES = 0.5）。然而，前锋的碰撞负荷（35 ± 12 任意单位）高于后卫（20 ± 6，99.9/0.1/0%，ES = 1.3），后锋的碰撞负荷最高（40 ± 13）。我们的示例比赛动作表现和冲击信息对教练和支持人员有价值，可以帮助他们为类似水平的橄榄球运动员准备球员资料，以帮助管理他们的工作量。
