Male academy rugby league players are required to undertake field and resistance training to develop the technical, tactical and physical qualities important for success in the sport. However, limited research is available exploring the training load of academy rugby league players. Therefore, the purpose of this study was to quantify the field and resistance training loads of academy rugby league players during a pre-season period and compare training loads between playing positions (i.e., forwards vs. backs). Field and resistance training load data from 28 adolescent male (age 17 ± 1 years) rugby league players were retrospectively analysed following a 13-week pre-season training period (85 total training observations; 45 field sessions and 40 resistance training sessions). Global positioning system microtechnology, and estimated repetition volume was used to quantify external training load, and session rating of perceived exertion (sRPE) was used to quantify internal training load. Positional differences (forwards n = 13 and backs n = 15) in training load were established using a linear mixed effect model. Mean weekly training frequency was 7 ± 2 with duration totaling 324 ± 137 minutes, and a mean sRPE of 1562 ± 678 arbitrary units (AU). Backs covered more high-speed distance than forwards in weeks two (p = 0.024), and 11 (p = 0.028). Compared to the forwards, backs completed more lower body resistance training volume in week one (p = 0.02), more upper body volume in week three (p< 0.001) and week 12 (p = 0.005). The findings provide novel data on the field and resistance-based training load undertaken by academy rugby league players across a pre-season period, highlighting relative uniformity between playing positions. Quantifying training load can support objective decision making for the prescription and manipulation of future training, ultimately aiming to maximise training within development pathways.
男性学院橄榄球联盟球员需要进行场地和阻力训练，以发展在该运动中取得成功所需的技术、战术和身体素质。然而，可用的关于学院橄榄球联盟球员训练负荷的研究有限。因此，本研究的目的是量化学院橄榄球联盟球员在赛季前期间的场地和阻力训练负荷，并比较不同位置（即前锋与后卫）的训练负荷。对 28 名青春期男性（年龄 17±1 岁）橄榄球联盟球员进行了回顾性分析，这些球员在为期 13 周的赛季前训练期间完成了 85 次总训练观察（45 次场地训练和 40 次阻力训练）。使用全球定位系统微技术和估计的重复量来量化外部训练负荷，并用会话感知努力评分（sRPE）来量化内部训练负荷。使用线性混合效应模型确定了训练负荷的位置差异（前锋 n=13，后卫 n=15）。每周训练频率平均为 7±2 次，持续时间总计 324±137 分钟，sRPE 平均值为 1562±678 任意单位（AU）。在第二周（p=0.024）和第 11 周（p=0.028），后卫比前锋覆盖更多的高速距离。与前锋相比，后卫在第一周完成了更多的下半身阻力训练量（p=0.02），在第三周（p<0.001）和第十二周（p=0.005）完成了更多的上半身阻力训练量。研究结果提供了学院橄榄球联盟球员在赛季前期间进行的场地和基于阻力的训练负荷的新数据，突出了不同位置之间的相对一致性。量化训练负荷可以为未来训练的规定和操纵提供客观决策，最终旨在最大限度地提高发展途径内的训练效果。
