This study was intended to investigate the associations between session Ratings of Perceived Exertion (sRPE) and Edwards' training load (TL) and Banister training impulse (TRIMP) in order to determine the validity of the sRPE method for TL assessment in karate kata discipline. Eight elite karate kata athletes, members of the national karate team, took part in this study. A multistage 20 m shuttle run test was performed to determine maximal heart rate (HR). Subsequently, the subjects performed 3 different kata training sessions separated by minimally 48 hours. To calculate Edwards TL, Banister TRIMP and sRPE, heart rate (HR) was continuously monitored during the sessions and RPE of the entire session was collected 30 minutes after each training session. The Pearson correlation coefficient (r) was used for determining associations between TL variables. Edwards TL (p = 0.064) and Banister TRIMP (p = 0.102) were not, but sRPE was significantly different between each training session (p < 0.001). There were no significant correlations between sRPE and Edwards TL (r = 0.53, p = 0.18) or Banister TRIMP (r = 0.13, p = 0.77) when data from all training sessions were pooled. A significant correlation was obtained between sRPE and Edwards TL (r = 0.71, p = 0.04) in situational training session, whereas in technical training session sRPE was significantly correlated with Banister TRIMP (r = 0.82, p = 0.01). HR-based methods for TL assessment are not able to discriminate between kata training sessions and, therefore, sRPE may be more useful for coaches to monitor TL in karate kata athletes.
本研究旨在调查单次训练的自感用力度（sRPE）与爱德华兹训练负荷（TL）以及班尼斯特训练冲量（TRIMP）之间的关联，以确定sRPE方法在空手道型比赛项目中评估训练负荷的有效性。八名国家空手道队的精英型比赛运动员参与了本研究。进行了多级20米往返跑测试以确定最大心率（HR）。随后，受试者进行了3次不同的型训练课程，每次课程间隔至少48小时。为了计算爱德华兹TL、班尼斯特TRIMP和sRPE，在训练过程中持续监测心率（HR），并在每次训练课程结束30分钟后收集整个课程的自感用力度（RPE）。使用皮尔逊相关系数（r）来确定训练负荷变量之间的关联。爱德华兹TL（p = 0.064）和班尼斯特TRIMP（p = 0.102）在各训练课程之间没有差异，但sRPE在各训练课程之间有显著差异（p < 0.001）。当汇总所有训练课程的数据时，sRPE与爱德华兹TL（r = 0.53，p = 0.18）或班尼斯特TRIMP（r = 0.13，p = 0.77）之间没有显著相关性。在情景训练课程中，sRPE与爱德华兹TL之间存在显著相关性（r = 0.71，p = 0.04），而在技术训练课程中，sRPE与班尼斯特TRIMP显著相关（r = 0.82，p = 0.01）。基于心率的训练负荷评估方法无法区分型训练课程，因此，sRPE可能对教练监测空手道型运动员的训练负荷更有用。
