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.
Over the long Christmas holidays and have already come to reflect on the resumption of physical activity, the more that extra few pounds precisely there. Where to start, so that was not painfully hard, but useful? Our advice is to swim!
The benefits of swimming in the pool, as a form of physical activity, it is difficult to overestimate: floating in the pool, you can seriously
improve your health and restore the body after physical and psychological injuries, and reduce/maintain weight.
The benefits of swimming in the pool is reflected in its beneficial effects on the cardiovascular system. Those who are constantly engaged in swimming, marked slowing of heart rate to 60 beats per minute or less. Continue reading
In all cases, adaptation is not difficult to distinguish between physiological adaptation in the form of installation activities to a new level of reference.
Scientific and technical progress deepens the relationship of society with nature, pushes the limits of the used environment, expands the range of human habitability. The intensity of natural resource development is
related to the fact that large numbers of people work in the high latitudes, within the boundaries of the coastal shelf, in the deserts. Even the mountains, until recently accessible only to mountaineers, became the area of industrial development.
Our Earth is not revealed Continue reading
