There are various factors which might promote muscle fatigue. For example, if you are particularly active when you are not normally.

Does muscle contraction always promote movement?

No , a muscle may be stretched with out movement .


Causes of muscle fatigue?

Muscle fatigue may be caused by overexertion or a lack of nutrition. Aside from these, the other two causes center around the nerve signal and the ability of the muscle fibers to contract properly.


How does temperature affect muscle fatigue?

at high temperatures, metabolites accumulate in activated muscle fibers thus reducing endurance. at low temperatures neuromuscular electrical transmission of the contractile properties of the muscle may lead to fatigue

What is muscle fatigue?

Muscle fatigue is the repeated, intense use of muscles which leads to a decline in performance.Though the actual mechanism for muscle fatigue appears to involve the leakage of calcium.The maximum intensity of exercise is determined by physiological factors such as the maximum rate of O2 uptake, maximum heart rate and stroke volume, maximum muscle strength, etc. In the case of maximum work, a time factor is involved. Muscle fatigue is the transient decrease in performance capacity of muscles, usually evidenced by a failure to maintain or develop a certain expected force or power. Fatigue curves vary between individuals and within individuals depending upon the conditions that exist. Muscle fatigue can occur in two basic mechanisms: (a) central involves proximal motor neurons (mainly in the brain); and (b) peripheral involves within the motor units (i.e., motor neurons, peripheral nerves, motor endplates, muscle fibers). In peripheral muscle fatigue there are at least two different sites where repeated contractions maycauseimpairment:the"transmission mechanism"(neuromuscular junction, muscle membrane, and endoplasmic reticulum), and the "contractile mechanism" (muscle filaments). As the mechanical response of the individual active muscle fibers decline with fatigue, a certain compensation can be achieved by increasing the innervation frequency and/or the number of active motor units. The reasons for the appearance of peripheral muscle fatigue are local changes in the internal conditions of the muscle. These may be biochemical, depletion of substrates such as glycogen, high energy phosphate compounds in the muscle fibers, and acetylcholine in the terminal motor nerve branches, or they may be due to the accumulation of metabolites, such as lactate or electrolytes liberated from the muscles during activity


What is chronic fatigue syndrome?

Chronic fatigue syndrome is a condition in which the person affected has extreme tiredness. They may also experience memory issues, unexplained muscle pain, and unrefreshing sleep.


How are ATp levels affected by muscle fatigue?

There has been no universal mechanism found to explain skeletal muscle fatigue. With the onset of intense exercise, muscle force has been shown to fall, which is often illustrated as a sign of fatigue. As ATP supplies the immediate energy to the muscle cell, the relationship between ATP and fatigue has been a topic of interest among researchers. During muscle contraction the majority of ATP is used for cross bridge cycling, ion pumps and transporters, and chemical signalling cascades. A fall in [ATP] would result in the development of rigor and goes against the viability of the cell. It is proposed that whole muscle [ATP] does not fall with repeated contraction, though there may be differences in [ATP] between fiber types with fatigue. Rather, fatigue is a protective mechanism by the muscle to preserve [ATP] accomplished by down regulating cellular processes that use ATP for energy


What's Chronic fatigue syndrome?

Chronic fatigue syndrome is a condition in which the person affected has extreme tiredness. They may also experience memory issues, unexplained muscle pain, and unrefreshing sleep.

How do you cure muscle fatigue?

Muscle fatigue is associated with the lack of ATP in the muscle and causes a weak feeling. What sometimes may only be 100 pounds, might feel like 200. There is no "driect cure" for muscle weakness, but often eating a bannana and taking a hot bath will help. It is also nessesary to have sufficient ammounts of viatimins in your body, this helps you get better faster.
