Why run the athlete-the enforcer

Running to improve health for all, or even athletes, so to speak, cross-country sports. Running for such athletes has its own characteristics and advantages. Let’s consider them in more detail.

We list the beneficial effects of regular practice of athletic training.

Firstly, running is able to deal with stress and insomnia, stimulating and soothing the nervous system. In addition, during the run produced specific substances, which, acting like a drug, improve mood and give a sense of

euphoria. Also running is able to deal with pain syndromes. It is noticed that post-workout pain go away much faster after running.

Secondly, running improves the cardiovascular system . It is proved that under the influence of processes while running dilate the lumen of the vessels, which leads to normalization groooming processes, prevents the formation of stagnation of blood in the muscles and organs. Normalized pressure and train the heart muscle. In addition, Continue reading

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. Physical exercise can help prevent the development of such unpleasant complications like incontinence and lower back pain, reduce the frequency of depressive moods, the probability of developing preeclampsia, improve control weight gain during pregnancy. It is assumed that the effect of physical activity is the activation of the parasympathetic division of the nervous system that leads to lower levels of cortisol – a stress hormone and to normalize blood

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
