Muscle Fatigue: The Role of Metabolism
Canadian Journal of Applied Physiology, 2002This paper examined the role of metabolites in causing muscle fatigue. Previous studies have shown that Pi [Formula: see text] and H+ may be important factors in causing fatigue. A key question is the potential interaction between metabolic end-products and calcium related excitation-contraction coupling fatigue (ECC).

Hyperventilation syndrome and muscle fatigue
Journal of Psychosomatic Research, 1988Fatigue is a frequent complaint from patients suffering from the hyperventilation syndrome. Fatigue was quantified in terms of the endurance time that a certain force can be generated in a sustained handgrip contraction, and in terms of the time course of changes in certain parameters of the EMG-power spectrum of the contracting muscles.

Neuromuscular Fatigue in Dystrophic Muscle
Nature, 1962THE effects of the dystrophic process upon muscle function are of continued interest. Dystrophic mouse muscle has been found to exhibit multiple action potentials, spontaneously, as well as in response to a single stimulus to its nerve1,2; d-tubocurarine or sustained, periodic single shock stimulation shortens the after-discharges1.

Change in manipulation with muscle fatigue
European Journal of Neuroscience, 2010AbstractMuscle fatigue is defined as an exercise‐induced reduction in the force‐generating capacity of muscle. Here, we investigated the effect of muscle fatigue on hand dexterity. Healthy adults (n = 17) gripped and lifted an object (0.342 kg) five times before and after two interventions.

MUSCLE PAIN, FATIGUE, AND FASICULATIONS
Neurologic Clinics, 1997This article discusses muscle pain, fatigue, and fasiculations. Muscle pain and fatigue are common problems in general medicine and in neurology, while fasiculations raise concern about a potentially ominous disease. The author reviews the conditions that cause pain and similar conditions arising from nonmuscular soft tissues.

Cellular mechanisms of muscle fatigue
Physiological Reviews, 1994Fatigue, defined as the failure to maintain the required or expected power output, is a complex problem, since multiple factors are clearly involved, with the relative importance of each dependent on the fiber type composition of the contracting muscles(s), and the intensity, type, and duration of the contractile activity. The primary sites of fatigue

Muscle Fatigue: The Cellular Aspects
The American Journal of Sports Medicine, 1996High-intensity contractile activity causes a rapid fall in peak tension or force, a reduced shortening velocity, decline in power, prolonged twitch duration, a sarcolemma action potential with a prolonged duration, reduced amplitude, and a conduction velocity that may result in conduction block.

The muscle fatigue fiber model
Mathematics and Computers in Simulation, 2010The aim of this study was to integrate the effect of muscle fatigue into the skeletal muscle fiber model, which was previously developed in our laboratory and was based on the modified Huxley equation with the calcium activation taken into account. The cellular mechanisms such as (i) the attachment of myosin heads to the actin binding sites, (ii) the ...

Are the antagonist muscles fatigued during a fatigue task of agonist muscles?
Isokinetics and Exercise Science, 2004The purpose of this study was to examine if a fatigue task of agonist muscles also causes fatigue to the antagonist muscles. Fourteen(n = 14) healthy males (age: 24.3 ± 2.5 y) participated in two isokinetic fatigue protocols (IFPs) at the angular velocity of 60°/s. The motion ranged from 0° to 90° of knee flexion.
