get muscle cramps. This can occur during strenuous
exercise or even at rest. The most common
cause of muscle cramps is dehydration. Muscle cramps happen involuntarily
and occur for longer periods with the muscles contracted. When it is not
prolonged, the involuntary contraction is called spasms and it is occasionally
referred as twitch.
If striated muscles contract rapidly for longer duration, it can cause muscular fatigue. Intense exercise causes the striated muscles to contract rapidly, which leads to the decrease of the force-generating capacity. It also causes the accumulation of lactic acid, which is said to be the cause of the fatigue.
