Velocity-Based Training (VBT) is an emerging method in resistance training for objectively prescribing and monitoring training intensity and neuromuscular function. Given its growing popularity, assessing the validity and reliability of VBT devices is critical for strength and conditioning coaches.
The primary purpose of this review was twofold: (1) to identify and address methodological gaps in current assessments of VBT device validity and reliability, and (2) to propose and apply a novel, multi-layered, criterion-based framework-developed in collaboration with statisticians and domain experts-for evaluating these devices.
A systematic search was conducted in PubMed, Scopus, and SPORTDiscus following PRISMA guidelines, focusing on original research studies published before February 2024 that assessed VBT device validity or reliability. Out of 568 studies identified, 75 met the inclusion criteria.
Among the included studies, 66 investigated device validity and 56 examined reliability, with some studies addressing both aspects. Notably, only 5 of the 66 validity studies met all of the proposed criteria, while just 16 of the 56 reliability investigations satisfied the required statistical thresholds defined by our framework. These findings highlight significant methodological variability and underscore the need for more standardized evaluation practices.
This review systematically evaluated the validity and reliability of various VBT devices and introduced a robust, multi-layered framework for their assessment. By integrating statistician-led and domain expert-led criteria, the framework offers a standardized approach that enhances the precision of device evaluation. Promising tools identified include the GymAware LPT, Perch Motion Capture Single Camera System, Flex optical device, and VmaxPro. Future research should build upon and refine this methodology to further standardize study designs, improve data reporting, and ultimately support more informed decision-making in sports technology and training practice.
基于速度的训练（VBT）是阻力训练中一种新兴的方法，用于客观地规定和监测训练强度以及神经肌肉功能。鉴于其越来越受欢迎，评估VBT设备的有效性和可靠性对于体能教练来说至关重要。
本综述的主要目的有两个：（1）识别并解决当前VBT设备有效性和可靠性评估方法上的差距；（2）提出并应用一个与统计学家和领域专家合作开发的新颖的、多层的、基于标准的框架来评估这些设备。
按照PRISMA指南在PubMed、Scopus和SPORTDiscus中进行了系统检索，重点关注2024年2月之前发表的评估VBT设备有效性或可靠性的原始研究。在识别出的568项研究中，75项符合纳入标准。
在纳入的研究中，66项研究调查了设备有效性，56项研究检验了可靠性，有些研究涉及两个方面。值得注意的是，66项有效性研究中只有5项符合所有提出的标准，而56项可靠性研究中只有16项满足我们框架定义的所需统计阈值。这些发现凸显了显著的方法学差异，并强调了更标准化评估实践的必要性。
本综述系统地评估了各种VBT设备的有效性和可靠性，并引入了一个强大的多层评估框架。通过整合由统计学家主导和领域专家主导的标准，该框架提供了一种标准化方法，提高了设备评估的精度。确定的有前景的工具包括GymAware LPT、Perch Motion Capture单相机系统、Flex光学设备和VmaxPro。未来的研究应在此方法的基础上进行完善，以进一步规范研究设计、改进数据报告，并最终支持体育技术和训练实践中更明智的决策。
