Muscle Fatigue: The Role of Metabolism

Canadian Journal of Applied Physiology, 2002
This 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).

Neuromuscular Fatigue in Dystrophic Muscle

Nature, 1962
THE 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.

Measurement of human muscle fatigue

Journal of Neuroscience Methods, 1997
Human muscle fatigue has been studied using a wide variety of exercise models, protocols and assessment methods. Based on the definition of fatigue as 'any reduction in the maximal capacity to generate force or power output', the different methods to measure fatigue are discussed.

Are the antagonist muscles fatigued during a fatigue task of agonist muscles?

Isokinetics and Exercise Science, 2004
The 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.

Muscle Fatigue: The Cellular Aspects

The American Journal of Sports Medicine, 1996
High-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, 2010
The 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 ...

Cellular mechanisms of muscle fatigue

Physiological Reviews, 1994
Fatigue, 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
