Nowadays, wearables are a must-have tool for athletes and coaches. Wearables can provide real-time feedback to athletes on their athletic performance and other training details as training load, for example. The aim of this study was to systematically review studies that assessed the accuracy of wearables providing real-time feedback in swimming. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were selected to identify relevant studies. After screening, 283 articles were analyzed and 18 related to the assessment of the accuracy of wearables providing real-time feedback in swimming were retained for qualitative synthesis. The quality index was 12.44 ± 2.71 in a range from 0 (lowest quality) to 16 (highest quality). Most articles assessed in-house built ( = 15; 83.3%) wearables in front-crawl stroke ( = 8; 44.4%), eleven articles (61.1%) analyzed the accuracy of measuring swimming kinematics, eight (44.4%) were placed on the lower back, and seven were placed on the head (38.9%). A limited number of studies analyzed wearables that are commercially available ( = 3, 16.7%). Eleven articles (61.1%) reported on the accuracy, measurement error, or consistency. From those eleven, nine (81.8%) noted that wearables are accurate.
如今，可穿戴设备是运动员和教练必备的工具。可穿戴设备可以为运动员提供有关其运动表现和其他训练细节（例如训练负荷）的实时反馈。本研究旨在系统地回顾评估可穿戴设备在游泳中提供实时反馈准确性的研究。选择了《系统评价和荟萃分析的首选报告项目》（PRISMA）指南来确定相关研究。经过筛选，分析了 283 篇文章，其中有 18 篇与评估可穿戴设备在游泳中提供实时反馈的准确性有关，被保留用于定性综合分析。质量指数为 12.44 ± 2.71，范围从 0（最低质量）到 16（最高质量）。大多数文章评估了自建（= 15；83.3%）的在自由泳中使用的可穿戴设备（= 8；44.4%），11 篇文章（61.1%）分析了测量游泳运动学的准确性，8 篇（44.4%）放在下背部，7 篇（38.9%）放在头部。少数研究分析了市售的可穿戴设备（= 3，16.7%）。有 11 篇文章（61.1%）报告了准确性、测量误差或一致性。其中有 9 篇（81.8%）指出可穿戴设备是准确的。
