Treadmill for home

Treadmill – one of the most popular cardio equipment. And this is not surprising, because the treadmill for the house activates the cardiovascular system, respiratory system and burns ligne fat, and also trains the muscles of the back and legs.

Home treadmills vary in size, system load and other characteristics. It is possible to select the treadmill you need to know more information about what are the different types of treadmills.

Types of treadmills for home

Motorized treadmill for home are the most cost-effective simulator, because the tape track rotates through the efforts of the runner. During walking or running, he gradually begins to rotate the tape. Thus, the mechanical path the electricity is not required, 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.
