AbstractA common belief in exercise physiology is that fatigue during exercise is caused by changes in skeletal muscle metabolism. This ‘periphera’ fatigue results either from substrate depletion during submaximal exercise or metabolite accumulation during maximal exercise in the exercising muscles. However, if substrate depletion alone caused fatigue, intracellular ATP levels would decrease and lead to rigor and cellular death. Alternatively, metabolite accumulation would prevent any increase… Expand
ROLE OF CENTRAL FATIGUE IN RESISTANCE AND ENDURANCE EXERCISES: AN EMPHASIS ON MECHANISMS AND POTENTIAL SITES
TLDR
The authors suggest that there is peripheral fatigue in both kinds of activities, however, the mechanisms of fatigue and the rate of perceived exertion are distinct. Expand
Logical limitations to the “catastrophe” models of fatigue during exercise in humans
TLDR
This paper addresses six hallmark physiological requirements that must be correct if Hill’s cardiovascular/ anaerobic/catastrophic model is the exclusive explanation for the fatigue that develops during maximum exercise to exhaustion. Expand
Effect of exercise-induced fatigue on postural control of the knee.
TLDR
It is shown that muscle fatigue induces a reduction and delay in the activation of both the quadriceps and hamstring muscles in response to rapid destabilizing perturbations potentially reducing the stability around the knee. Expand
Peripheral fatigue is not critically regulated during maximal, intermittent, dynamic leg extensions.
TLDR
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.

Muscle Fatigue in Males and Females during Multiple-Sprint Exercise
TLDR
It is highlighted that sex differences in the absolute mechanical work performed during a given task might explain a significant part of the differences in physiological responses of males and females to sprint exercise and is suggested that future studies using male and female subjects to answer basic physiological questions use mechanical work as a covariate. Expand
Decline in voluntary activation contributes to reduced maximal performance of fatigued human lower limb muscles
TLDR
During prolonged intermittent maximal dorsiflexions the performance of ankle muscles declines despite enhanced corticospinal excitability presumably due to deficient descending drive and/or spinal motoneuron responsiveness to the cortical drive. Expand
Is the notion of central fatigue based on a solid foundation?
TLDR
A simulation model developed indicated that the force behavior commonly attributed to central fatigue could be explained solely by peripheral factors during simulated fatiguing submaximal voluntary contractions and revealed important flaws regarding the use of the interpolated twitch response from electrical stimulation of the muscle as a means for assessing central fatigue. Expand
Corticomotor excitability contributes to neuromuscular fatigue following marathon running in man
TLDR
Results suggest that fatigue after a marathon was attributable to both a disturbance of the contractile apparatus within the muscle and submaximal output from the motor cortex. Expand
Neuromotor Mechanisms Involved in the Recovery from Local Muscular Fatigue
TLDR
It was concluded that over-recovery was not present in the tibialis anterior following a local muscular fatigue, however, the return in force to initial values, rather than a persistent decrement as normally observed, was mediated by the warm-up effect. Expand

Changes in muscle contractile properties and neural control during human muscular fatigue
TLDR
Evidence is presented that, in fatigue of sustained maximal voluntary contractions (MVC) executed by well‐motivated subjects, the reduction in force generating capacity need not be due to a decline in central nervous system motor drive or to failing neuromuscular transmission, but can be attributed solely to contractile failure of the muscles involved.

TLDR
This review considers four additional models that need to be considered when factors limiting either short duration, maximal or prolonged submaximal exercise are evaluated, and provides a broad overview of the physiological, metabolic and biomechanical factors that may limit exercise performance under different exercise conditions.

TLDR
Increased fatigue resistance would appear to depend on carefully planned programmes designed to adapt the excitation and contraction processes, the cytoskeleton and the metabolic systems, not only to tolerate but also to minimize the changes in the intracellular environment that are caused by the intense activity.

Fatigue and exhaustion in chronic hypobaric hypoxia: influence of exercising muscle mass.
TLDR
Interactive electromyogram activity (IEMG) and mean (MPF) and centroid (CPF) power frequencies of the EMG power spectrum during exercise were calculated for forearm flexors and vastus lateralis muscle in chronic hypobaric hypoxia. Expand

TLDR
It appears likely that this condition is associated with and likely caused by muscle injury, such that the SR releases less Ca2+ at low frequencies of activation, and LFF could result from a reduced membrane excitability,such that the sarcolemma action potential frequency is considerably less than the stimulation frequency.

TLDR
The 'plasticity' of fibre properties is discussed with reference to the 'acute' changes elicited by exercise induced fatigue and changes in muscle temperature and 'chronic' changes occurring following intensive training and ageing. Expand
Depression of human electromyographic activity by fatigue of a synergistic muscle
TLDR
In human volunteers, lateral gastrocnemius muscles were stimulated electrically under ischemic conditions so as to produce fatigue and a significant reduction of the EMG could still be demonstrated 10 min after release of the arterial cuff, consistent with the existence of an inhibitory reflex effect.

This work proposes four themes that provide a basis for the systematic evaluation of the neural and neuromuscular fatigue mechanisms and suggests a number of experiments to advance the understanding of the neurobiology of muscle fatigue. Expand

Tests of Maximum Oxygen Intake A Critical Review
TLDR
While there is some specificity of training when conditioning is based upon small muscle groups, treadmill training apparently improves cardiac performance, and thus V̇O2max, in many other types of endurance activity, which varies with the type of exercise. Expand
