The use of inertial measurement unit (IMU) has become popular in sports assessment. In the case of velocity-based training (VBT), there is a need to measure barbell velocity in each repetition. The use of IMUs may make the monitoring process easier; however, its validity and reliability should be established. Thus, this systematic review aimed to (1) identify and summarize studies that have examined the validity of wearable wireless IMUs for measuring barbell velocity and (2) identify and summarize studies that have examined the reliability of IMUs for measuring barbell velocity. A systematic review of Cochrane Library, EBSCO, PubMed, Scielo, Scopus, SPORTDiscus, and Web of Science databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From the 161 studies initially identified, 22 were fully reviewed, and their outcome measures were extracted and analyzed. Among the eight different IMU models, seven can be considered valid and reliable for measuring barbell velocity. The great majority of IMUs used for measuring barbell velocity in linear trajectories are valid and reliable, and thus can be used by coaches for external load monitoring.
惯性测量单元 (IMU) 的使用在运动评估中变得越来越流行。在基于速度的训练 (VBT) 的情况下，需要测量每个重复的杠铃速度。使用 IMU 可能会使监测过程更加容易；但是，应该确定其有效性和可靠性。因此，本系统评价旨在：(1) 确定并总结检查可穿戴无线 IMU 测量杠铃速度的有效性的研究，以及 (2) 确定并总结检查 IMU 测量杠铃速度的可靠性的研究。根据系统评价和荟萃分析的首选报告项目 (PRISMA) 指南，对 Cochrane Library、EBSCO、PubMed、Scielo、Scopus、SPORTDiscus 和 Web of Science 数据库进行了系统评价。从最初确定的 161 项研究中，对 22 项进行了全面审查，并提取和分析了它们的结果指标。在八种不同的 IMU 模型中，有七种可被认为可有效和可靠地测量杠铃速度。用于测量线性轨迹中杠铃速度的绝大多数 IMU 都是有效和可靠的，因此可以由教练用于外部负载监测。
