To assess the convergent validity of the Borg CR100® scale to track internal training load (TL) in youth football players.
A total of 19 youth football players (age = 15 [1] y, height = 175.9 [12.3] cm, and body mass = 69 [15.4] kg) were monitored for 27 sessions, including training and games. Internal TL was assessed via session rating of perceived exertion (sRPE) and 2 heart-rate-based methods (Banister training impulse and Edwards TL). The correlations between sRPE and heart-rate-based TL, the differences in individual player intercepts and slopes, and the differences between types of sessions (training vs games) were assessed using a general linear mixed model with magnitude-based inferences.
Correlations between sRPE and Banister training impulse were very large at overall group level (r = .77; 90% confidence limits, .72-.80) and individual level (range .70-.95). Correlations between sRPE and Edwards TL were very large at overall group level (r = .84; 90% confidence limit, .82-.86) and large to very large at individual level (range .64-.93). A very likely small difference was found in the comparison between games and training sessions for the relationship between sRPE and Banister training impulse.
The Borg CR100 scale is a valid method for monitoring TL in youth football players.
评估 Borg CR100® 量表在跟踪青少年足球运动员内部训练负荷（TL）方面的聚合效度。
共有 19 名青少年足球运动员（年龄=15 [1] 岁，身高=175.9 [12.3] 厘米，体重=69 [15.4] 千克）被监测了 27 次，包括训练和比赛。内部 TL 通过训练感知评估（sRPE）和 2 种基于心率的方法（班尼斯特训练冲动和爱德华兹 TL）进行评估。使用基于幅度的推断的一般线性混合模型评估 sRPE 与基于心率的 TL 之间的相关性、个体运动员截距和斜率的差异，以及不同类型的课程（训练与比赛）之间的差异。
在总体组和个体组水平上，sRPE 与班尼斯特训练冲动之间的相关性非常大（r=.77；90%置信区间，.72-.80）。在总体组和个体组水平上，sRPE 与爱德华兹 TL 之间的相关性非常大（r=.84；90%置信区间，.82-.86），个体水平的相关性为大到非常大（范围.64-.93）。在比较训练和比赛时，sRPE 与班尼斯特训练冲动之间的关系存在非常小的可能差异。
Borg CR100 量表是监测青少年足球运动员 TL 的有效方法。
