A large number of power meters have become commercially available during the last decades to provide power output (PO) measurement. Some of these power meters were evaluated for validity in the literature. This study aimed to perform a review of the available literature on the validity of cycling power meters. PubMed, SPORTDiscus, and Google Scholar have been explored with PRISMA methodology. A total of 74 studies have been extracted for the reviewing process. Validity is a general quality of the measurement determined by the assessment of different metrological properties: Accuracy, sensitivity, repeatability, reproducibility, and robustness. Accuracy was most often studied from the metrological property (74 studies). Reproducibility was the second most studied (40 studies) property. Finally, repeatability, sensitivity, and robustness were considerably less studied with only 7, 5, and 5 studies, respectively. The SRM power meter is the most used as a gold standard in the studies. Moreover, the number of participants was very different among them, from 0 (when using a calibration rig) to 56 participants. The PO tested was up to 1700 W, whereas the pedalling cadence ranged between 40 and 180 rpm, including submaximal and maximal exercises. Other exercise conditions were tested, such as torque, position, temperature, and vibrations. This review provides some caveats and recommendations when testing the validity of a cycling power meter, including all of the metrological properties (accuracy, sensitivity, repeatability, reproducibility, and robustness) and some exercise conditions (PO range, sprint, pedalling cadence, torque, position, participant, temperature, vibration, and field test).
在过去的几十年中，大量的功率计已经商业化，用于提供功率输出（PO）测量。其中一些功率计在文献中已经过有效性评估。本研究旨在对现有的关于自行车功率计有效性的文献进行综述。本研究采用 PRISMA 方法，检索了 PubMed、SPORTDiscus 和 Google Scholar。共提取了 74 项研究进行综述。有效性是测量的一般质量，由不同计量特性的评估决定：准确性、灵敏度、重复性、再现性和稳健性。准确性是最常从计量特性（74 项研究）来研究的。再现性是第二大研究（40 项研究）的特性。最后，重复性、灵敏度和稳健性的研究相对较少，分别只有 7、5 和 5 项研究。SRM 功率计是研究中最常用的金标准。此外，研究中的参与者数量差异很大，从 0（当使用校准架时）到 56 名参与者。测试的 PO 高达 1700W，而踏频范围在 40 到 180rpm 之间，包括次最大和最大运动。还测试了其他运动条件，如扭矩、位置、温度和振动。本综述提供了一些在测试自行车功率计的有效性时需要注意的事项和建议，包括所有计量特性（准确性、灵敏度、重复性、再现性和稳健性）和一些运动条件（PO 范围、冲刺、踏频、扭矩、位置、参与者、温度、振动和现场测试）。
