Photoplethysmography (PPG) heart rate devices are greatly affected by the motion artifacts of running. As a result, their application in training load systems and effort control strategies based on heart rate (HR) could be debatable. In 2019, Polar applied some new features on their PPG devices to improve their accuracy. Thus, the purpose of this study was to determine the level of agreement between the new PPG system Polar Precision Prime™ and the chest strap Polar H10 (reference system) in the HR monitoring during an interval running protocol. A group of 37 long distance runners completed an interval running protocol of 10 min composed of five 1-min trials with an active break of 1-min between each trial. An excellent reliability (ICC > 0.9) was obtained for the entire interval running protocol with the lowest values in the first 2 min (ICC = 0.960–0.949), slight differences between intensities (ICC = 0.992–0.986), and a reduction of the observed tendency (ICC > 0.9) when the Edwards quantification model was applied (ICC = 0.877–0.967). The Bland-Altman plots with the final HR values of each trial establish a systematic bias (<1 bpm) for all intervals with a random error (<4 bpm), except in the first trial which had a higher random error (6.85 bpm). In conclusion, the innovations applied in the new PPG system provide the accuracy required for use in diverse functions, including endurance running.

光电容积脉搏波 (PPG) 心率设备受跑步运动伪影的影响很大。因此，它们在训练负荷系统和基于心率 (HR) 的努力控制策略中的应用可能存在争议。2019 年，Polar 在其 PPG 设备上应用了一些新功能，以提高其准确性。因此，本研究的目的是确定新 PPG 系统 Polar Precision Prime™ 和胸带 Polar H10（参考系统）在间歇跑步方案期间心率监测中的一致性水平。一组 37 名长跑运动员完成了 10 分钟的间歇跑方案，该方案由五次 1 分钟的试验组成，每次试验之间有 1 分钟的主动休息。出色的可靠性（ICC > 0. 9) 在前 2 分钟内获得最低值 (ICC = 0.960–0.949)、强度之间的细微差异 (ICC = 0.992–0.986) 以及观察到的趋势的减少 (ICC > 0.9) ) 当应用 Edwards 量化模型时 (ICC = 0.877–0.967)。带有每个试验最终 HR 值的 Bland-Altman 图为所有具有随机误差 (<4 bpm) 的间隔建立了系统偏差 (<1 bpm)，除了第一次试验具有更高的随机误差 (6.85 bpm) . 总之，在新 PPG 系统中应用的创新提供了在包括耐力跑在内的各种功能中使用所需的准确性。9) 当应用 Edwards 量化模型时 (ICC = 0.877–0.967)。带有每个试验最终 HR 值的 Bland-Altman 图为所有具有随机误差 (<4 bpm) 的间隔建立了系统偏差 (<1 bpm)，除了第一次试验具有更高的随机误差 (6.85 bpm) . 总之，在新 PPG 系统中应用的创新提供了在包括耐力跑在内的各种功能中使用所需的准确性。9) 当应用 Edwards 量化模型时 (ICC = 0.877–0.967)。带有每个试验最终 HR 值的 Bland-Altman 图为所有具有随机误差 (<4 bpm) 的间隔建立了系统偏差 (<1 bpm)，除了第一次试验具有更高的随机误差 (6.85 bpm) . 总之，在新 PPG 系统中应用的创新提供了在包括耐力跑在内的各种功能中使用所需的准确性。
