The critical power (CP) concept has been extended from cycling to the running field with the development of wearable monitoring tools. Particularly, the Stryd running power meter and its 9/3-minute CP test is very popular in the running community. Locating this mechanical threshold according to the physiological landmarks would help to define each boundary and intensity domain in the running field. Thus, this study aimed to determine the CP location concerning anaerobic threshold, respiratory compensation point (RCP), and maximum oxygen uptake (VO2max).
A group of 15 high-caliber athletes performed the 9/3-minute Stryd CP test and a graded exercise test in 2 different testing sessions.
Anaerobic threshold, RCP, and CP were located at 73% (5.41%), 86.82% (3.85%), and 88.71% (5.84%) of VO2max, respectively, with a VO2max of 66.3 (7.20) mL/kg/min. No significant differences were obtained between CP and RCP in any of its units (ie, in watts per kilogram and milliliters per kilogram per minute; P ≥ .184).
CP and RCP represent the same boundary in high-caliber athletes. These results suggest that coaches and athletes can determine the metabolic perturbance threshold that CP and RCP represent in an easy and accessible way.
随着可穿戴监测工具的发展，临界功率（CP）概念已从自行车运动扩展到跑步领域。特别是，Stryd跑步功率计及其9/3分钟CP测试在跑步群体中非常受欢迎。根据生理标志来确定这个力学阈值将有助于定义跑步领域中的每个边界和强度域。因此，本研究旨在确定与无氧阈、呼吸补偿点（RCP）和最大摄氧量（VO2max）相关的CP位置。
一组15名高水平运动员在2个不同的测试环节中进行了9/3分钟的Stryd CP测试和递增负荷运动测试。
无氧阈、RCP和CP分别位于VO2max的73%（5.41%）、86.82%（3.85%）和88.71%（5.84%）处，VO2max为66.3（7.20）毫升/千克/分钟。CP和RCP在任何单位（即每千克瓦特数和每千克每分钟毫升数）上均未获得显著差异（P≥0.184）。
在高水平运动员中，CP和RCP代表相同的边界。这些结果表明，教练和运动员可以以一种简单且可及的方式确定CP和RCP所代表的代谢扰动阈值。
