Muscle fatigue is the decline in ability of a muscle to generate force. It can be a result of vigorous exercise but abnormal fatigue may be caused by barriers to or interference with the different stages of muscle contraction. There are two main causes of muscle fatigue - limitations of nerve’s ability to generate a sustained signal and the reduced ability of calcium (Ca2+) to stimulate contraction.

Famous quotes containing the word fatigue:
“Avarice is generally the last passion of those lives of which the first part has been squandered in pleasure, and the second devoted to ambition. He that sinks under the fatigue of getting wealth, lulls his age with the milder business of saving it.”
—Samuel Johnson (1709–1784)
