In intermittent team and racquet sports, metabolic loads are rarely investigated as they are difficult to examine, e.g., by portable metabolic carts and lactate measures. However, determining the instantaneous metabolic power of intermittent running from acceleration and speed data is possible. Recently, this potential has gained more interest in research and practice due to the development of player tracking technologies that allow easy access to the required data. The aim of this review was to systematically investigate the validity and point out the evidence of this new approach for estimating metabolic loads in intermittent sports. To provide an in-depth understanding of this approach and its validity, the fundamental aspects of the underlying concept were also considered.
PubMed®, Cochrane Library, Web of Science™, and BISp-surf databases were included in the search conducted on March 1, 2021. Studies assessing physiological and methodological validation as well as conceptual studies of the metabolic power approach in intermittent sports players without diseases or injuries were deemed eligible. The quality assessment was implemented using a modified 12-item version of the Downs and Black checklist. Additionally, a best-evidence synthesis of the validation studies was performed to clarify the direction and strength of the evidence.
Of 947 studies that were identified, 31 met the eligibility criteria of which 7 were physiological, 13 methodological validation, and 11 conceptual studies. Gold standards for validating the metabolic power approach were predominantly oxygen uptake with 6 and traditional running speed analysis with 8 studies for physiological and methodological validation, respectively. The best-evidence synthesis showed conflicting to strong and moderate to strong evidence for physiological and methodological validity of the approach, respectively. The conceptual studies revealed several modifications regarding the approach that need to be considered. Otherwise, incorrect implementation can occur.
Evidence of the physiological validity of the metabolic power approach ranged from conflicting to strong. However, this should be treated with caution as the validation studies were often partially implemented incorrectly as shown by the underlying concept studies. Moreover, strong evidence indicated that the approach is valid from a methodological perspective. Future studies must consider what the metabolic power approach can and cannot actually display.
在间歇性团队运动和球拍类运动中，由于难以通过便携式代谢推车和乳酸测量等方式进行检测，代谢负荷很少得到研究。然而，根据加速度和速度数据来确定间歇性跑步的瞬时代谢功率是可行的。近年来，由于球员追踪技术的发展，能够轻松获取所需数据，这种潜力在研究和实践中受到了更多关注。本综述的目的是系统地研究这种用于估算间歇性运动中代谢负荷的新方法的有效性，并指出相关证据。为了深入理解这种方法及其有效性，还考虑了其基础概念的基本方面。
2021年3月1日进行检索时纳入了PubMed®、Cochrane图书馆、科学网™和BISp-surf数据库。评估无疾病或损伤的间歇性运动运动员代谢功率方法的生理和方法学验证以及概念性研究的文献被视为符合要求。使用修改后的12项版唐斯和布莱克检查表进行质量评估。此外，对验证研究进行了最佳证据综合分析，以阐明证据的方向和强度。
在检索到的947项研究中，31项符合纳入标准，其中7项为生理学研究，13项为方法学验证研究，11项为概念性研究。验证代谢功率方法的金标准主要是摄氧量（生理学验证有6项研究）和传统跑步速度分析（方法学验证有8项研究）。最佳证据综合分析表明，该方法在生理学和方法学有效性方面的证据分别为相互矛盾到强以及中等强度到强。概念性研究揭示了该方法需要考虑的几个改进之处。否则，可能会出现错误的实施情况。
代谢功率方法的生理学有效性证据从相互矛盾到强不等。然而，鉴于基础概念研究表明验证研究常常部分实施错误，对此应谨慎对待。此外，有力证据表明该方法从方法学角度是有效的。未来的研究必须考虑代谢功率方法实际能够和不能展示的内容。
