The effect of branched-chain amino acid ingestion on physical performance during prolonged exercise
… the increased brain serotonin content may induce central fatigue during prolonged exercise. Until present, this postulate had not been subject to rigorous scientific testing during prolonged exercise. Therefore the aim of this study was to investigate whether ingesting a BCAA supplement during …

The use of free tryptophan and prolactin as peripheral indices of brain serotoninergic activity
The central fatigue hypothesis suggests that during prolonged exercise, the increased plasma free-tryptophan (f-Trp) concentration may lead to an increased rate of synthesis of brain serotonin (5-HT). This may impair central nervous system function and cause increased perceptions of fatigue and …

Central and peripheral fatigue in response to the acute and chronic metabolic demand: implications for exercise tolerance
Fatigue and the associated exercise limitation has wide reaching human performance and health implications, however the mechanisms are poorly understood. Muscle fatigue during exercise originates from a combination of peripheral and central processes, and their interaction, which are influenced by …

Mechanisms of fatigue during prolonged exercise in the heat
… tolerance in the heat and the sensitivity of central serotonergic and dopaminergic pathways further indicates the importance of dopamine in central fatigue. The action of caffeine in enhancing endurance performance has been shown not to involve the hypothalamus and this draws attention to …

Genetic factors associated with performance and exercise-associated weight loss in Ironman triathletes
… which have been implicated in peripheral and central fatigue models. Candidate genes (5-HTT and AVPR2) that encode for proteins that play key roles in the neuro-endocrine control of total body water homeostasis were also investigated in this thesis.

An Environmental and Durability Study of Bonded Structural Patch Repairs with Finite Element and Machine Learning Enabled Predictions
… bonded patch subjected to quasi-static and fatigue loads under various environmental conditions. The patch repair technique is widely applied to thin, damaged specimens, particularly in the field of aircraft structures, where maintaining structural integrity while minimizing additional …

Pushing the limits of performance. is it really mind over matter? an investigation into the effects of menthol mouth rinsing and the capacity for fatigue amelioration in trained adolescent male cyclists under heat stress
… responses (exertion, thermal stimulation, fatigue, and feeling), and blood lactate were recorded. The MEN MR significantly improved mean power output by 1.81±1.57% relative to PLA (p=<0.001, 95% CI= [1.73-4.46], ES= 1.53). Physiological and perceptual measures did not differ between trials. …

The Effects of Carbohydrate Mouth Rinse on Fasted High-Intensity Interval Training in Recreationally Trained Individuals
… participating in HIIT whilst fasting by reducing central fatigue. This study investigated the effects of CHO on fasted HIIT performance in recreationally trained individuals. Method: Using a double-blind, placebo-controlled, randomised crossover design, the study involved 15 recreationally trained …

Effect of Palm Temperature on Fatigue During High Intensity Bench Press Exercise
… 4 sets of 85% 1RM bench press exercise to fatigue, with 3min rest intervals. Exercise trials were performed in counterbalanced order on three days, separated by at least 3 days; Thermoneutral (TN), Palm Heating (PH), and Palm Cooling (PC). Heating and cooling were applied using the RTX set …

Central and peripheral determinants of fatigue in acute hypoxia
Fatigue is defined as an exercise-induced decrease in maximal voluntary force produced by a muscle. Fatigue may arise from central and/or peripheral mechanisms. Supraspinal fatigue (a component of central fatigue) is defined as a suboptimal output from the motor cortex and measured using …

Redox regulation of vascular NO bioavailability during hypoxia: implications for oxygen transport and exercise performance
… a reduction in O2 supply with contributions from central and peripheral origins of fatigue. Changes in cerebral and muscle oxygenation have not been well characterised during incremental exercise in hypoxia. It is possible attainment of O2peak is driven by the oxygenation profile of these tissues …

The Role of Monocyte Chemotactic Protein-1 In the Development of Central Nervous System Fatigue In Healthy Mice and In Response to Cancer Chemotherapy
<p>Fatigue is a symptom experienced by most people but can be a destructive symptom in those with a disease or a disorder, causing more severe problems. Our preliminary data suggested a possible role of monocyte chemotactic protein-1 (MCP-1) in the occurrence of fatigue, especially in fatigue …

Neuromuscular Fatigue and Biomechanical Alterations during High-Intensity, Constant-Load Cycling
Neuromuscular fatigue is an inevitable process at play during prolonged exercise, and may be caused by multiple alterations within the central nervous system and peripheral musculature. As fatigue develops, the neuromuscular system must adapt to these changes by making compensatory movement pattern …
