Skeletal muscle fatigue is your muscles getting feeling tired after activity. My project is about why your muscles feel this way. There are two explanations that scientists argue over to explain this. One has to do with the buildup of lactic acid and the pH of the muscle. The other explanation is the resupplying of ATP to the muscles. This subject interest me because muscles in general have always interested me. This subject is also in everyday life so it is good to know about.

Skeletal muscle fatigue has two major explanations that scientist are still discussing. Their predictions at the moment for the cause are Metabolic Acidosis and the Hydrolysis of Phosphocreatine. Metabolic acidosis is the occurrence of extra acid in a tissue. In this case, the tissue is muscle. As physical activity is performed, there is a release of lactic acid. The body has the ability to dispose of this acidity through the kidneys. When the body can’t keep up, this is when metabolic acidosis develops. The muscle pH becomes off and fatigue begins to set in. According to others, Hydrolysis of Phosphocreatine is the cause. This occurs as the body uses ATP. When a muscle contacts, ATP is used to power this process. After the ATP is used ADP is left over. Muscles have a limited supply of ATP so there is a need for the replenishment. The body accomplishes this through the hydrolysis of phosphocreatine. Phosphocreatine sends a high-energy phosphate to ADP to create ATP and the by-product is creatine. This process is said to cause muscle fatigue.
The two main components of skeletal muscle fatigue are metabolic acidosis and hydrolysis of phosphate creatine or phosphocreatine. In a more understandable way the development of lactic acid through the use of ATP and the regeneration of it.
the anaerobic metabolism and muscle fatigue have a causal relationship
now it is thought that hydrolysis of phosphocreatine causes it
Causes of metabolic acidosis
due to the pH of blood becoming off
process of hydrolysis of phosphocreatine
The meaning of metabolic acidosis and general information
chemicals in metabolic acidosis
evidence of lactate production helping reduce muscle fatigue
lactate production occurs to retard acidosis
phosphocreatine helps supply ATP
creatine phosphate transfers a high-energy phosphate to ADP
products of this are creatine and ATP (adenosine diphosphate)
