Answer:

The causes of cramps are varied:

-Low accumulation of metabolites affecting the contraction

-Low amount of electrolytes

-fluid loss

-stress associated with the environment, such as heat and cold.

Explanation:

Although these are some factors that produce cramps, they are not the only ones, it is necessary to take into account if the person has a history of cramps, or to compete at a faster rate than the rhythm of training. Sometimes these cramps occur in the types of muscles that intersect with two joints. Another possible cause of cramping has to do with the accumulation of lactic acid causing persistent contraction in the muscle.
