The effects of the lumbopelvic manipulation on the fatigability of the back and hip muscles in adults with chronic low back pain
… pain (CLBP) have been shown to have increased fatigability levels of hip and low back muscles as measured by the surface electromyographic (EMG) median frequency (MF). In addition, literature suggests that lumbopelvic manipulation could be an effective intervention for reducing CLBP. However, …

Quantification of muscle fatigue in cerebal palsy and its relationship to impairments and function
… also associated with higher levels of muscle fatigability. Strength was directly related to muscle fatigability, where weaker subjects had lower levels of fatigue, regardless of muscle. Cocontraction and quadriceps stiffness, on the other hand, were inversely related to muscle fatigability. …

Cognitive Correlates Of Fatigue In Pediatric-Onset Multiple Sclerosis
… and clinical features of POMS, namely objective fatigability, and subjective fatigue. Fatigability was operationalized as response time variability on a brief version of the Continuous Performance Test (CPT). We found that there is a significantly greater probability of parents and participants …

The development and origin of muscle fatigue after hexagonal-barbell deadlift exercise of different loads and velocities: contributing to a knowledge-base for coaches to make evidence-informed decisions regarding athletic training programmes
… literature has proposed terms of performance fatigability and perceived fatigability to better describe the broad interpretation of fatigue during human performance. Accordingly, performance fatigability depends on the capabilities of the contractile machinery and nervous system to provide …

Comparing self-report and objective physical activity in fatigue outcomes for persons with MS and high-BMI
… examined their relationships with fatigue and fatigability. The purpose of this study was to examine the relationships between subjective and objective physical activity measures and fatigue outcomes in people with multiple sclerosis and obesity.This study was a cross-sectional secondary …

USING ADDITIONAL MEASURES OF HANDGRIP STRENGTH TO PREDICT AEROBIC CAPACITY IN WHEELCHAIR USERS
… maximal HGS, HGS rate of force development, HGS fatigability, HGS isometric control, and HGS asymmetry to a six-minute wheelchair propulsion (6MPT) test in ambulatory young adults. Thirty-four recreationally active ambulatory individuals aged 23.76±3.57yrs participated in this study. HGS was …

TRANSLATIONAL APPROACH TO NEUROMUSCULAR FUNCTION AND ITS RECOVERY: EFFECT OF LIMBS, AGING, AND DISEASE.
… can ultimately determine neuromuscular function fatigability. Furthermore, the time course of neuromuscular function recovery after exercise is essential for planning repeated daily activities and sports. My PhD work aimed to compare the effects of different fatiguing exercises, populations, and …

The psychophysiological regulation of pacing behaviour and performance during prolonged endurance exercise
… determines pacing behaviour and performance fatigability. A three-dimensional framework of centrally regulated and goal-directed exercise behaviour is proposed, which differentiates between sensory-discriminatory, affectivemotivational, and cognitive-evaluative processes hypothesised to …

The effects of N-acetylcysteine infusion on performance, glutathione and ion regulation during voluntary exercise in humans
… compound 7V-acetylcysteine (NAC) reduced fatigability in electrically evoked human muscle contractions, but numerous adverse reactions were reported. No studies have investigated NAC infusion effects during voluntary exercise in humans. This thesis investigated whether an NAC infusion …

Structural and contractile alterations in skeletal muscles from the genetically obese (ob/ob) mouse: impairment or adaptation?
… thereby slowing relaxation. (Chapter 5). 4. The fatigability characteristics [fatigue resistance; recovery of peak tetanic force at 5 min and 60 min after cessation of fatiguing exercise; loss in the ability to generate force at stimulation frequencies of 5 to 90 (or 110) Hz, at 60 min after …

The influence of myosin regulatory light chain phosphorylation on the contractile performance of fatigued mammalian skeletal muscle
… the effect of skMLCK gene ablation on the fatigability of mouse skeletal muscles during repetitive stimulation. The absence of myosin RLC phosphorylation in skMLCK knockout muscles attenuated contractile performance without a significant metabolic cost. Twitch force was potentiated to a …

Electro-chemical stimulation of neuromuscular systems using ion-selective membranes : flexible device fabrication and motor unit recruitment order
… response in muscle contraction and by high fatigability due to the reversal of recruitment order of motor units. Previous work showed that ion-selective membranes can be used to modulate Ca 2 ions in situ, decreasing the current threshold for nerve stimulation and eliciting a more graded …

The integration of neuromuscular, perceptual, and cardiorespiratory fatigue responses is modulated by high intensity interval training characteristics and blood flow restriction in males and females
… Additionally, BFR resulted in a greater rate of fatigability compared to control in females than males. Collectively, the findings demonstrate that longer HIIT work periods and the application of BFR reduce exercise capacity, which can be attributed to modulated psychophysiological alterations. …

Can low-dose lithium supplementation protect against sarcopenic obesity in ovariectomized mice?
… production of soleus and EDL in OVX mice. Muscle fatigability was improved in soleus, but not EDL, of sham and OVX mice provided with Li supplementation. Glucose handling and insulin sensitivity were not affected by Li treatment, however, fasting blood glucose levels were improved with Li …

Statin-associated skeletal muscle damage and its interactions with novel or accustomed exercise
… groups showed decrements in muscle force and fatigability with statin treatment. The effect on maximal force was more severe in the novel-exercise group, while accustomed exercise mice were protected from this decrement. Plasma creatine kinase levels did not correlate with functional outcomes. …

Impacts of blood flow occlusion on the human neuromuscular system
… of blood flow. The result is enhanced muscle fatigability. The four studies in this thesis investigate how BFO acutely affects muscle fatigue, the neuromuscular system, muscle contractile properties and motor unit firing rates, using a combination of electrical stimulation, transcranial …
