Muscle Fatigue - Reduced Contraction Capacity Of The Muscles

Muscle fatigue is an athlete's nightmare, and it has been a cause, which has hindered many artists and their performances. Thus people, especially sportsmen try hard to avoid it by taking many supplements and extra care. Following are some reasons why fatigue of the muscles is caused -

Causes of muscle fatigue - Chemistry at work

One of the main reasons that are known to be the cause of muscles fatigue is build up of lactic acid in the body, which takes place during exercise. What this lactic acid does is forms a salt containing a lactate cell and a free H plus compound. The increase of this H compound in the cells makes the PH to decrease thus becoming more acidic. This acid in the muscles causes fibers' calcium-binding capacity to decrease, which reduces muscle contraction, ultimately leading to muscle fatigue.

Prolonging muscle fatigue

Most people would like to prolong, especially players and sportsmen. Muscle fatigue can be prolonged or delayed by decreasing or reducing the acid build up in the body by buffering it with a basic compound like bicarbonates, proteins and organic acids etc. These are present in the body itself, although in small quantities. When the PH decreases and becomes more acids, these basic compounds balance the equilibrium. Apart from this method, consumption of sodium bicarbonate can also help if an effective dose is taken. This kick starts the body and approximately Sodium bicarbonate equivalent to 0.3 kg of the body weight should be consumed.

Muscle fatigue mechanisms

Fatigue varies between individuals depending upon their subjective conditions. Muscle fatigue occurs basically in two basic mechanisms. Following are the two basic mechanisms that it occurs in -

* Central fatigue - This involves proximal motor neurons generally in the brain.
* Peripheral fatigue - This is within the motor neurons of the peripheral nerves, motor endplates, muscle fibers etc. The peripheral muscle fatigue has 2 sites where contractions may cause impairments. The two sites are transmission mechanism (muscle membrane) and contractile mechanism (muscle filaments).
Central and peripheral fatigue may be separate or combined, but that depends upon the specific situation and condition of the athlete.

Muscle fatigue treatment

Muscle fatigue can be treated by aromatherapy muscle oils, which can be used to massage the certain points of pain or fatigue. Also adequate fluid intake, medication and stretching exercises can treat the fatigue of the muscles.
