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 to stimulate contraction.
Muscle fatigue is often confused with the breaking down of muscles in normal use. You have to break a muscle down to re-built it stronger and bigger. Fatigue can often cause the person to stop exercise for periods of time. Again, you need to wear a muscle down and work it until you feel like you can not flex it one more inch but do not go to the point of damage that is sustained or requires attention.
Stay strong and work your muscles. There is not better way to stay healthy and active. Love the burn it is a valuable feeling.
