Lactic acid:
Lactate is an abnormal accumulation of acid in the tissues and body fluids. Lactate is produced by sugary substances during its fermentation process due to the breakdown of sugar with the hypoxia of the muscles, and the increase in the percentage of the muscles during the performance of anaerobic muscle, where multiple contractions leads to constriction of blood vessels Which leads to increased production of lactate and this is one of the factors leading to muscle fatigue, and at rest becomes part of the glycogen, and the other part is converted to (H2 o & co2).
The production of blood lactate during the maximum exercise is due to limited availability of oxygen at the level of mitochondria. It is assumed that part of the debate about the production of lactate during exercise is related to the lack of oxygen at the cellular level can be analyzed at least in two ways:
- Cell breathing is affected by partial oxygen pressure (p o 2).
- Cellular metabolism is affected by the partial pressure of carbon dioxide.
The availability of oxygen is not the determining factor for increased lactate production during exercise. The rate of lactate production during exercise is determined by exercise intensity and anaerobic processes
The lactic acid is present in the resting state of more than 10 milligrams (about 1 mM / L). However, the ratio is increased in high intensity sports activities. This increase has an effect on the degree of blood balance between acidic and alkaline (ph) blood and the concentration of lactic acid in the blood Affected by two factors.
- The speed of lactic exit from the muscles to the blood.
- The speed of the speed of removal of acid from the blood, and in general the speed of the exit of lactic to the blood is linked to the amount of contact through the cells to the blood.
Lactate production increases at the onset of physical activity regardless of the intensity of this activity in the working muscles. This is due to the slow production of aerobic energy and insufficient oxygen delivery to the working muscles as required. Thus, these muscles consume glycogen without the presence of oxygen, And the amount of lactic acid produced by the muscle depends on three factors:
- The severity of physical pregnancy.
- The size of the physical load.
- Working muscle size.
It turns a large part of the lactic acid resulting from the performance of the anaerobic physical activity to the Profik acid again and then breaks down the presence of oxygen within the mitochondria to give free energy in addition to carbon dioxide and water. It can also perform lactic acid outside the muscle to use other muscles to produce energy, The lactic acid can also be transmitted by blood to the liver where it is converted into glycogen. This glycogen can be converted into glucose and then transferred back through the blood to the muscle to be used in aerobic or anaerobic energy production. The performance of sports activities for long periods as well as during recovery of the hospital, which helps to remove lactic acid causing fatigue.
