Muscle fatigue is a quite common condition, and can be experienced by everybody. This type of fatigue occurs anytime the muscles cannot exert normal force, or when more effort than normal is required to achieve a desired level of force. The muscle pain is a normal response to unusual exertion and is part of an adaptation route that leads to better stamina and strength as the muscles recover and build hypertrophy. Muscle hypertrophy is the growth and increase of the size of muscle cells, and it usually occurs as a result of physical exercise such as weight lifting.

Causes of muscle fatigue

Muscular fatigue may occur for a number of different reasons. Sometimes, the reasons behind muscle fatigue are completely genetic, while it remains self-induced in great majority of cases.

The most common reason behind muscle fatigue is physical exercise, and it usually occurs as a delayed reaction, appearing 12-48 hours after the exercise. This type of muscle pain is the most common at the beginning of a new exercise program or after a considerable increase in the intensity of the exercise. This kind of pain is worse within the first 2 days following the activity then diminishes over the next couple of days.

Anemia is another common cause of muscle fatigue. The pain in the muscles occurs when there is not enough oxygen supplied to the muscle cells. Consequently, the muscles cannot function at their optimum and the patient develops symptoms of muscular fatigue.Certain medications are also associated with muscular fatigue. The pain in the muscles appears as their side effect. Both prescribed or over-the-counter medications may cause muscular fatigue, but this happens only in a small number of cases.

Any kind of thyroid disease is tightly associated with weakness and fatigue. Both low and high thyroid levels are associated with muscular pain and weakness, among many other symptoms such as lethargy, memory problems, intolerance to cold or heat, etc.

Other known causes involve stress, diabetes and various heart diseases.

Treatment for muscle fatigue

The first step to successful treatment is to find out what kind of condition or activity causes muscular pain. If the fatigue results from a physical exercise, patient should consider a change in the exercise program and make sure he or she gets enough rest and relaxation during the day. A gentle massage may also help to relieve the symptoms.

If any other medical condition causes muscular fatigue, patient should get involved in a controlled treatment and cure the underlying problem. A good nutritional supplement and a proper diet are recommended for any treatment during muscle fatigue.
