Journal of Electromyography and Kinesiology, 1991
Myoelectric signal variables and mechanical variables are known to change during sustained voluntary or electrically elicited contractions. These phenomena reflect changes in the properties of the muscle fiber and its membrane. Such changes are generally called "fatigue." Muscle fiber conduction velocity and myoelectric signal spectral parameters (mean

Neurobiology of muscle fatigue
Journal of Applied Physiology, 1992Muscle fatigue encompasses a class of acute effects that impair motor performance. The mechanisms that can produce fatigue involve all elements of the motor system, from a failure of the formulation of the descending drive provided by suprasegmental centers to a reduction in the activity of the contractile proteins. We propose four themes that provide

Abstract Skeletal muscle fatigue is defined as the fall of force or power in response to contractile activity. Both the mechanisms of fatigue and the modes used to elicit it vary tremendously. Conceptual and technological advances allow the examination of fatigue from the level of the single molecule to the intact

Skeletal muscle fatigue is a complex problem which deserves attention from physiotherapists and other clinical practitioners. This article will discuss the findings of recent literature to explore some of the main mechanisms thought to underlie fatigue in skeletal muscles. These mechanisms may be peripheral in origin, occurring within the muscle fibres

Ventilatory failure may accompany a variety of pulmonary and neuromuscular diseases. There has been much controversy about whether this failure is due to respiratory muscle fatigue at peripheral sites or a failure of drive at sites within the central nervous system. The chapter reviews this topic.

ABSTRACT. Muscle fatigue and pain are together common symptoms which can be analysed physiologically. For many patients attending a medical clinic the problem for the doctor is to decide whether the problem is “in the mind” or “in the muscle”. A history of the symptoms occurring at rest without any exercise is a hint of psychological origin.

The contribution of respiratory muscle fatigue to the development of ventilatory failure has been the subject of considerable interest and has stimulated much research. Experimental studies in dogs have shown respiratory muscle fatigue to be a cause of ventilatory failure in both cardiogenic and septic shock models.

Respiratory Muscle Fatigue Alters Cycling Performance and Locomotor Muscle Fatigue
Medicine & Science in Sports & Exercise, 2020ABSTRACT Purpose This study aimed to determine if preexisting respiratory muscle fatigue (RMF) alters motoneuronal output, locomotor muscle fatigue, and cycling performance. Methods Eight trained male cyclists performed 5-km cycling time trials after a resistive breathing ...

Development of Mobile Muscle Fatigue Display Based on Muscle Fatigue Scale
2020 IEEE International Conference on Consumer Electronics (ICCE), 2020This paper describes our developed biofeedback device based on muscle fatigue scale (MFS). At present, Japan faces the issues of population decrease and a super-aging society. Extension of healthy life expectancy and reduction of health disparities are especially the ultimate objectives that should be realized in Japan through the improvement of ...

When respiratory muscle demands for energy exceed supplies, the energy stored within the muscles is depleted and the force of contraction diminishes. This state is called inspiratory muscle fatigue. When it occurs alveolar ventilation decreases, arterial carbon dioxide tension (PaCO2) increases and hypercapnic respiratory failure ensues.
