I’m Mark Burnley the lead author on this paper. The aim of this paper was to review the power-duration (PD) relationship in the physiology and fatigue that underpins it. Particularly in relation to the critical power (CP) concept. In this review we looked at the intensity domains that are associated with exercise. In other words, the moderate intensity domain, below the lactate threshold (LT), the heavy intensity domain between LT and CP or the maximum lactate steady state and sever-intensity exercise, which occurs above the CP.

The major message of this review is that the fatigue mechanisms that attend exercise depend upon the exercise intensity domain in which the exercise is performed. The secondary message of this paper is that fatigue in each domain affects multiple organ systems and therefore no single mechanism of fatigue can be set to limit exercise tolerance.
We hope you enjoy the paper.
