Inflammation of the muscles (muscle soreness) is the result of intensive muscle training load at the start of training period or after a period of reduced work or brake. Acute inflammation of the muscles occurs at the end of the training, while the deferred inflammation develops day or two after training. Muscle inflammation, whether it is an infection of an individual muscle or muscle groups hoped, in fact arise when a particular muscle or muscle group formed by excess secretion of lactic acid.

Lactic acid is a product of metabolism, which occurs due to an insufficient supply of oxygen in muscle tissue. This phenomenon occurs due to strenuous exercise, since blood vessels through which oxygen delivery to muscle tissue, do not achieve to provide and transmit sufficient oxygen. In proportion, it is clear that the inflammation of the muscles stronger and more painful, if in them a greater presence of lactic acid and lactic acid secretion degree, directly depends on the pace of physical activity or exercise and whether the oxygen supply to the tissues is sufficient or not. When intense muscular effort, the pace of creation of lactic acid is much faster than the pace of removal and therefore its concentration in the blood rises.

Accelerating the elimination of lactate from the blood, created during exercise, would have positive effects in terms of faster recovery of the body. The concentration of lactate in the blood decreases rapidly during the recovery phase, if it continues with muscle exertion of lower intensity. Active recovery in the form of moderate physical activity more effectively speeds up the removal of lactate than passive recovery, due to the fact that the dispute is activated muscle fibers that metabolize lactate generated during exercise.

It should take into account the interval workout that can maintain low levels of lactate, to reduce muscle fatigue and increase the quantity of labor. Warming up before and stretching after training are still one of the recommendations. Also, a moderate walk, resulting in the elimination of inflammation, will help and adequate intake of fluids in the body and enhanced intake of magnesium, which acts to prevent the occurrence of spasms and muscle spasm, which often accompany painful inflammation. Sore muscles can heal and cold compress. On painful areas can put some ice or something cold, but always make sure for frostbite.
