Answer: Fibrous pericardium and Serous Pericardium

Jeremy’s family just moved to Louisiana
ch4aika [34]

Jeremy is going with dehydration and electrolyte imbalance which commonly thought to be the cause of muscle cramps. This is most evident factor when training in hot and humid conditions due to an increased loss of electrolytes through sweat.

Exercise associated muscle cramps are mainly treated with hydration and electrolyte supplementation but this could be neglecting the underlying cause of cramps during or after exercise. The most effective way of treating cramps before they affect body athletic performance is neuromuscular re-education.

What is neuromuscular re-education?

Neuromuscular re-education involves training weak, underactive muscles to help balance the work load..

Charle horse is type of a cramp which occurs when the muscle involuntarily contracts and cannot relax. The calves and thighs are two of the most common areas affected, although cramps can strike hands, arms, abdomen, and feet. They typically last from several seconds to a few minutes, and athletic person can often feel a knot when presses the painful area.
