The duration that exercise can be maintained decreases as the power requirements
increase. In this review, we describe the power–duration (PD) relationship across the full …

The hyperbolic form of the power-duration relationship is rigorous and highly conserved
across species, forms of exercise and individual muscles/muscle groups. For modalities …

The curvilinear relationship between power output and the time for which it can be sustained
is a fundamental and well-known feature of high-intensity exercise performance. This …

Key points The power‐asymptote (critical power; CP) of the hyperbolic power–time
relationship for high‐intensity exercise defines a threshold between steady‐state and non …

Lactate or gas exchange threshold (GET) and critical power (CP) are closely associated with
human exercise performance. We tested the hypothesis that the limit of tolerance (Tlim) …

A popular concept in the exercise sciences holds that fatigue develops during exercise of
moderate to high intensity, when the capacity of the cardiorespiratory system to provide …

INTRODUCTION: Changes in the parameters of the power-time relationship (critical power
(CP) and W') during endurance exercise would have important implications for performance …

New Findings What is the central question of this study? We asked whether exercise
performance is regulated during all‐out repeated sprints (involving peak cycling‐specific …

prolonged, fatiguing exercise. J Appl Physiol 94: 2181–2187, 2003.—The hypothesis that …

Limitations in energy supply is a classical hypothesis of muscle fatigue. The present paper
reviews the evidence available from human studies that energy deficiency is an important …
