Load monitoring in Australian football (AF) has been widely adopted, yet team-sport periodization strategies are relatively unknown. The authors aimed to quantify training and competition load across a season in an elite AF team, using rating of perceived exertion (RPE) and GPS tracking.
Weekly totals for RPE and GPS loads (including accelerometer data; PlayerLoad) were obtained for 44 players across a full season for each training modality and for competition. General linear mixed models compared mean weekly load between 3 preseason and 4 in-season blocks. Effects were assessed with inferences about magnitudes standardized with between-players SD.
Total RPE load was most likely greater during preseason, where the majority of load was obtained via skills and conditioning. There was a large reduction in RPE load in the last preseason block. During in-season, half the total load came from games and the remaining half from training, predominantly skills and upper-body weights. Total distance, high-intensity running, and PlayerLoad showed large to very large reductions from preseason to in-season, whereas changes in mean speed were trivial across all blocks. All these effects were clear at the 99% level.
These data provide useful information about targeted periods of loading and unloading across different stages of a season. The study also provides a framework for further investigation of training periodization in AF teams.
澳大利亚足球(AF)中的负荷监测已被广泛采用,但团队运动的周期化策略相对未知。作者旨在使用感知用力评分(RPE)和 GPS 跟踪来量化精英 AF 球队一个赛季中的训练和比赛负荷。
对 44 名球员在每个训练模式和比赛中的整个赛季的 RPE 和 GPS 负荷(包括加速度计数据;PlayerLoad)进行每周总和计算。使用球员间标准差进行标准化的效应大小推断,对 3 个预备赛季和 4 个比赛赛季的平均每周负荷进行了一般线性混合模型比较。
在预备赛季,总 RPE 负荷很可能更大,其中大部分负荷是通过技能和体能训练获得的。在最后一个预备赛季,RPE 负荷大幅下降。在比赛赛季期间,总负荷的一半来自比赛,另一半来自训练,主要是技能和上身重量训练。总距离、高强度跑动和 PlayerLoad 从预备赛季到比赛赛季有大幅度到非常大幅度的减少,而所有这些影响在所有阶段都微不足道。所有这些效应都在 99%的水平上非常明显。
这些数据提供了有关在赛季不同阶段进行有针对性的加载和卸载时期的有用信息。该研究还为进一步调查 AF 球队的训练周期化提供了框架。
