■TRIMP和sRPE都是训练负荷(TL)的代表性指标,两者之间的相关性已经在各种运动中得到了广泛的证明。这项研究的目的是调查不同强度/持续时间的越野滑雪训练中sRPE-TRIMP相关性的可靠性,在心率数据丢失的情况下,sRPE是否可以作为TRIMP数据的有效性补充。
■10名运动员作为实验对象。强度,收集了273次不同类型的培训课程的持续时间和RPE,采用统计学方法进行数据分析。
■1.sRPE与TRIMP之间存在显著的相关性(r=0.68,p<0.05),但是LIT之间的相关性不同,MIT和HIT组(r=0.70,0.46,r=0.31,p<0.05)2。LIT组三个不同持续时间之间的sRPE-TRIMP相关性(0-60分钟,60-120分钟和120-180分钟),均极显著(r=0.70,0.67,0.69,p<0.05),3个持续时间的LRsRPE-TRIMP无显著差异(chow检验,p>0.05)。3.样本间实际训练时间的差异是sRPE应用效果差异的主要原因,因为LIT的实际训练持续时间比为89.7±16.4%;MIT,98.5±6.2%;命中,94.4±13.5%。
■1.LIT中sRPE与TRIMP(LRsRPE-TRIMP)的线性关系比MIT和HIT更为显著。2.LIT会话持续时间的变化不影响sRPE和TRIMP之间关系的一致性。3.实际和计划培训持续时间之间的差异直接影响LRsRPE-TRIMP的重要性。
UNASSIGNED: TRIMP and sRPE are both representative indicators of training load(TL), and the correlation between two has been widely demonstrated across various sports. The aim of this study was to investigate the reliability of sRPE-TRIMP correlation across different intensities/duration of training in cross-country skiing, and whether sRPE can serve as an validity supplement to TRIMP data in cases of lost heart rate data.
UNASSIGNED: 10 athletes were used as the experimental objects. The intensity, duration and RPE of 273 different types of training sessions were collected, and statistical methods were used for data analysis.
UNASSIGNED: 1. There was a significant correlation between sRPE and TRIMP (r = 0.68, p < 0.05), but the correlation differs among the LIT, MIT and HIT groups (r = 0.70, 0.46, r = 0.31, p < 0.05) 2. sRPE-TRIMP correlation among three different time duration in the LIT group (0-60 min, 60-120 min and 120-180 min), are all highly significant (r = 0.70, 0.67, 0.69, p < 0.05) and the LRsRPE-TRIMP of 3 duration have no significant differences (chow test, p > 0.05). 3. The difference in actual training duration between samples was the main reason for the difference in the application effect of sRPE, because the actual training duration ratio of LIT was 89.7 ± 16.4%; MIT, 98.5 ± 6.2%; and HIT, 94.4 ± 13.5%.
UNASSIGNED: 1. The linear relationship between sRPE and TRIMP (LRsRPE-TRIMP) is more significant in LIT compared to that in MIT and HIT. 2. Variations in the duration of LIT sessions do not affect the consistency of the relationship between sRPE and TRIMP. 3. Discrepancies between actual and planned training durations directly impact the significance of the LRsRPE-TRIMP.
