摘要

从生理学的角度来看,稳态运动和非稳态运动(也称为最大代谢稳态)之间的界限对于评估运动成绩、设计和监控训练计划至关重要。临界功率和最大乳酸稳态是两个被广泛用于估算这一阈值的指标,但之前的研究一直报告称,它们的相关功率输出之间存在显著差异。这些发现引发了关于临界功率和最大乳酸稳态在实践中是否可以互换的争论。本文回顾了确定这些阈值的内在方法论的复杂性,并阐明了不恰当的确定方法和研究之间的方法论不一致是如何导致文献中记录的差异的。通过对相关文献的批判性研究,并结合我们的实验室数据,我们证明了在采用适当而严格的测定标准时,临界功率与最大乳酸稳态之间的差异可能仅为几瓦特,因此在实践中这两种指数都可用于估算最大代谢稳态阈值。为此,我们定义了一套良好实践指南,以帮助科学家和教练获得最有效的临界功率和最大乳酸稳态估计值。

Critical Power and Maximal Lactate Steady State in Cycling: "Watts" the Difference?

Critical Power and Maximal Lactate Steady State in Cycling: "Watts" the Difference?

From a physiological perspective, the delineation between steady-state and non-steady-state exercise, also referred to as the maximal metabolic steady state, holds paramount importance for evaluating athletic performance and designing and monitoring training programs. The critical power and the maximal lactate steady state are two widely used indices to estimate this threshold, yet previous studies consistently reported significant discrepancies between their associated power outputs. These findings have fueled the debate regarding the interchangeability of critical power and the maximal lactate steady state in practice. This paper reviews the methodological intricacies intrinsic to the determination of these thresholds, and elucidates how inappropriate determination methods and methodological inconsistencies between studies have contributed to the documented differences in the literature. Through a critical examination of relevant literature and by integration of our laboratory data, we demonstrate that differences between critical power and the maximal lactate steady state may be reconciled to only a few Watts when applying appropriate and strict determination criteria, so that both indices may be used to estimate the maximal metabolic steady-state threshold in practice. To this end, we have defined a set of good practice guidelines to assist scientists and coaches in obtaining the most valid critical power and maximal lactate steady state estimates.
