Abstract

Objective: To investigate the correlation between different workload methods among Olympic curling athletes.

Materials and methods: Eight curlers were monitored after training during Olympic seasons with three load quantification methods: external load measurements, physiological/biochemical markers, and Omegawave state indices. Intraclass Correlation Coefficient and Bland-Altman plots were used to analyze the Session-RPE index [sRPE workload (RPE × session duration), acute:chronic workload ratio (ACWR), etc.], external [number of draws (the number of curling stones thrown during training/competition), training duration, etc.], and internal [physiological and biochemical indices (testosterone, etc.), and Omegawave sport performance evaluation system indices (comprehensive readiness, etc.)] workloads.

Results: The sRPE index was significantly correlated with external loads and Omegawave sport performance indicators at the 0.01 level (p < 0.01); it was significantly correlated with cortisol and creatine kinase at the 0.05 level (p < 0.05). In the standardized ICC and Bland-Altman plot concordance analyses, the sRPE correlates showed moderate (0.4 < ICC < 0.6) to strong (0.6 < ICC < 0.8) concordance with the corresponding external loading indices, the Omegawave athletic status indices, and average (0.2 < ICC < 0.4) to moderate agreement with the corresponding physiological and biochemical indicators.

Conclusions: The sRPE is a valid curling training-load tool capturing sport-specific demands but retains psychosocial limitations. Appropriate methods should be selected based on actual conditions and needs when choosing how to quantify and evaluate training load.

奥运冰壶运动员工作量量化的会话- rpe。
目的:探讨奥运冰壶运动员不同负荷方式的相关性。材料和方法:对8名冰壶运动员在奥运季训练后进行监测,采用三种负荷量化方法:外负荷测量、生理/生化指标和omegawwave状态指数。采用组内相关系数(Intraclass Correlation Coefficient)和Bland-Altman图分析了会话-RPE指标[sRPE工作量(RPE ×会话时长)、急慢负荷比(ACWR)等]、外部[抽签次数(训练/比赛中掷掷冰壶的次数)、训练持续时间等]、内部[生理生化指标(睾酮等)和omegwave运动表现评价体系指标(综合准备等)]的工作量。结果:sRPE指数与外负荷和omegawwave运动表现指标在0.01水平上显著相关(p < 0.05)。结论:sRPE是一种有效的冰壶训练负荷工具,可捕获运动特定需求,但仍存在心理社会局限性。在选择如何量化和评估培训负荷时,应根据实际情况和需要选择合适的方法。
