Muscle activity


Whatever it was, for a long period of implementation of two-phase muscle activity. ochevidnoj neobhodimo permanent restoration ( re-synthesis) adenosine triphosphate as the muscle it is quickly consumed. As a result of this constant regeneration ( resynthesis) adenosine triphosphate at the expense of other metabolic processes in the number of its muscles at a

moderate work practically does not change. Only at very long and hard work there has been some decrease in the content of ATP in muscle tissue.

From the above data it follows that in the implementation of the two-phase muscle activity plays a very important role in the mechanism of regulation of the sarcoplasmic reticulum content in muscle fibers CA ion. The binding and release of CA ions in the sarcoplasm, probably depends on the change of the potential sarcoplasmatic-ical membranes. The magnitude of the potentials of these membranes, in turn, can very quickly be changed under the influence of nerve impulses.

Physical activity during pregnancy

It was once thought that exercise is unacceptable for a pregnant woman. Today all believe that exercise is not only useful, but necessary for future mothers and their babies during uncomplicated pregnancy.

pressure. Exercise also increases the secretion of serotonin, reducing pain and frequency of depressive moods. There is evidence that regular exercise during pregnancy improves in the future the child’s cognitive ability, i.e. the ability to learn.

However, even if a pregnant feels great and the pregnancy proceeds without complications, before Continue reading
