Fatigue during prolonged exercise is often described as an acute impairment of exercise performance that leads to an inability to produce or maintain a desired power output. In the past few decades, interest in how athletes experience fatigue during competition has grown enormously. Research has evolved from a dominant focus on peripheral causes of fatigue towards a complex interplay between peripheral and central limitations of performance. Apparently, both feedforward and feedback mechanisms…

Cardiovascular Determinants Involved in Pacing Under Heat Stress
- MedicineSports Medicine
- 2013
The authors conclude that ‘‘recent literature showed that during exercise in the heat, a reduction in power output and muscle activation occurs before a critical core temperature is reached, indicating that subjects can anticipate the exercise intensity and heat stress they will be exposed to; thereby preventing catastrophic outcomes’’.
Peripheral fatigue is not critically regulated during maximal, intermittent, dynamic leg extensions.
- BiologyJournal of applied physiology
- 2014
Severe hypoxia exacerbates both peripheral fatigue development and performance decrements during maximal, intermittent, dynamic leg extensions and during exercise involving a single muscle group the attenuation of central motor drive does not appear to independently regulate the development of peripheral muscle fatigue.
Factors affecting the regulation of pacing: current perspectives
- PsychologyOpen access journal of sports medicine
- 2014
A new perspective is described, which proposes how exercise-induced pain may be a contributing factor in helping individuals to regulate their work rate during exercise and thus provides an important construct in pacing.
Is recovery driven by central or peripheral factors? A role for the brain in recovery following intermittent-sprint exercise
- PsychologyFront. Physiol.

The potential contributions of the brain to performance recovery after strenuous exercise is outlined, with a limited focus on contributors to post-exercise recovery from CNS origins.

: During exercise, there is a progressive reduction in the ability to produce muscle force. Processes within the nervous system as well as within the muscles contribute to this fatigue. In addition…
Authors’ Reply to Périard: “Cardiovascular Determinants Involved in Pacing Under Heat Stress”
- BiologySports Medicine
- 2013
The data demonstrate that the cardiovascular system is a coinfluencer of exercise performance (and thus pacing strategy) that cannot be overlooked, and encourage scientists to further unravel the mechanisms behind changes in pace and the onset of fatigue, certainly during prolonged exercise bouts in the heat.
Pacing Profiles in Competitive Track Races: Regulation of Exercise Intensity Is Related to Cognitive Ability
- PsychologyFront. Physiol.
- 2016
The hypothesis that runners with intellectual impairment have difficulties to efficiently self-regulate their exercise intensity during competitive track races is supported, as their limited cognitive resources may constrain the successful integration of appropriate pacing strategies during competitive races.
Effect of Environmental and Feedback Interventions on Pacing Profiles in Cycling: A Meta-Analysis
- PsychologyFront. Physiol.
- 2016
The available data suggests exercise regulation in hypoxia and heat-stress is delayed in the start section of trials, before significant reductions in MPO occur in the middle and end of the trial, and performance improvements can be retained when participants are informed of the deception.
Drive in Sports: How Mental Fatigue Affects Endurance Performance
- PsychologyFront. Psychol.
- 2018
This Perspective aims to show how mental fatigue affects endurance performance via two main mechanisms: perceived effort and reward, and studies the interaction between mental fatigue and other factors impacting on drive, such as perceived exertion and motivation.

A conceptual model for how the RPE mediates feedforward, anticipatory regulation of exercise performance is proposed and this model is applied to previously described research studies of exercise in various conditions, including heat, hypoxia and reduced energy substrate availability.
The Role of Information Processing Between the Brain and Peripheral Physiological Systems in Pacing and Perception of Effort
- PsychologySports medicine
- 2006
It is proposed that an internal clock, which appears to use scalar rather than absolute time scales, is used by the brain to generate knowledge of the duration or distance still to be covered, so that power output and metabolic rate can be altered appropriately throughout an event of a particular duration ordistance.

The purpose of this proposed feedback loop would be to regulate and restrict the development of exercise-induced peripheral muscle fatigue and/or associated sensory feedback to an "individual critical threshold" to prevent excessive disturbance of muscle homeostasis and potential harm to the organism.

A simple index, the product of the momentary Rating of Perceived Exertion (RPE) and the fraction of race distance remaining, the Hazard Score, defines the likelihood that athletes will change their velocity during simulated competitions and may effectively represent the language used to allow anticipatory regulation of muscle power output.
The physiological regulation of pacing strategy during exercise: a critical review

The present review evaluates the evidence for a complex pacing strategy by investigating studies in which interventions such as elevated temperature, altered oxygen content of the air, reduced fuel availability and misinformation about distance covered have resulted in alterations to the pacing strategy.
Exercising with reserve: evidence that the central nervous system regulates prolonged exercise performance
- MedicineBritish Journal of Sports Medicine

The ingestion of a centrally acting stimulant allowed subjects to exercise for longer at higher cardiorespiratory and metabolic stress indicating the presence of a muscular reserve in the natural state, suggesting that endurance performance is not only “limited” by mechanical failure of the exercising muscles.
Locomotor muscle fatigue modifies central motor drive in healthy humans and imposes a limitation to exercise performance
- Biology, EngineeringThe Journal of physiology

It is suggested that feedback from fatiguing muscle plays an important role in the determination of central motor drive and force output, so that the development of peripheral muscle fatigue is confined to a certain level.

The various pacing profiles that have previously been observed are outlined and possible factors influencing the self-selection of such strategies are discussed, including the rate and capacity limitations of anaerobic and aerobic energy supply/utilization are particularly influential in dictating the optimal pacing strategy during exercise.

It is suggested that noradrenaline, but not dopamine reuptake inhibition, contributes to the development of central/supraspinal fatigue after a prolonged cycling exercise performed in temperate conditions.

Dopaminergic reuptake inhibition appears to counteract hyperthermia‐induced fatigue in 30 °C, while noradrenergic neurotransmission shows negative effects on performance in both normal and high temperature, and serotonergic manipulations did not lead to significant changes in performance.
