To investigate the application of differential ratings of perceived exertion (dRPE) to team-sport training.
Single cohort, observational study.
Twenty-nine professional rugby union players were monitored over a six-week intensified training period. Training sessions were classified as: high-intensity intervals, repeated high-intensity efforts, speed, skill-based conditioning, skills, whole-body resistance, or upper-body resistance. After each session, players recorded a session rating of perceived exertion (sRPE; CR100), along with differential session ratings for breathlessness (sRPE-B), leg muscle exertion (sRPE-L), upper-body muscle exertion (sRPE-U), and cognitive/technical demands (sRPE-T). Each score was multiplied by the session duration to calculate session training loads. Data were analysed using mixed linear modelling and multiple linear regression, with magnitude-based inferences subsequently applied.
Between-session differences in dRPE scores ranged from very likely trivial to most likely extremely large and within-session differences amongst dRPE scores ranged from unclear to most likely very large. Differential RPE training loads combined to explain 66-91% of the variance in sRPE training loads, and the strongest associations with sRPE training load were with sRPE-L for high-intensity intervals (r=0.67; 90% confidence limits ±0.22), sRPE-B for repeated high-intensity efforts (0.89; ±0.08) and skill-based conditioning (0.67; ±0.19), sRPE-T for Speed (0.63; ±0.17) and Skills (0.51; ±0.28), and sRPE-U for resistance training (whole-body: 0.61; ±0.21, upper-body: 0.92; ±0.07).
Differential RPE can provide a detailed quantification of internal load during training activities commonplace in team sports. Knowledge of the relationships between dRPE and sRPE can isolate the specific perceptual demands of different training modes.
探讨主观用力程度差异评分（dRPE）在团队运动训练中的应用。
单队列观察性研究。
对29名职业橄榄球联盟球员进行了为期六周的强化训练监测。训练课程分为：高强度间歇训练、重复高强度训练、速度训练、基于技能的体能训练、技能训练、全身阻力训练或上身阻力训练。每次训练后，球员记录主观用力程度评分（sRPE；CR100），以及关于呼吸急促（sRPE-B）、腿部肌肉用力（sRPE-L）、上身肌肉用力（sRPE-U）和认知/技术要求（sRPE-T）的差异训练评分。每个分数乘以训练时长以计算训练负荷。使用混合线性模型和多元线性回归分析数据，随后应用基于量级的推断。
dRPE分数的训练课程间差异范围从极可能微不足道到极可能极大，dRPE分数的训练课程内差异范围从不明确到极可能非常大。差异RPE训练负荷综合起来解释了sRPE训练负荷方差的66 - 91%，与sRPE训练负荷最强的关联是：高强度间歇训练中与sRPE-L相关（r = 0.67；90%置信区间±0.22），重复高强度训练（0.89；±0.08）和基于技能的体能训练（0.67；±0.19）中与sRPE-B相关，速度训练（0.63；±0.17）和技能训练（0.51；±0.28）中与sRPE-T相关，阻力训练（全身：0.61；±0.21，上身：0.92；±0.07）中与sRPE-U相关。
差异RPE可以对团队运动中常见训练活动期间的内部负荷进行详细量化。了解dRPE与sRPE之间的关系可以区分不同训练模式的特定感知要求。
