The human body is constructed so that in the course of the activity to make both statistical, and dynamic movements. This muscle work provides as the habitual and ordinary movements connected with long sitting, standing on one place and so on, and walking, run, jumps and sports activities.
What does dynamic muscle work differ from statistical in?
Statistical work natural is also necessary for the person for performance of monotonous movements often for a long time. For example, during the work at the computer the person sits in the same situation several hours. The gas and arc welder is forced to hold long time an instrument of labor absolutely not movably qualitatively to perform the work. And in that and other case the held-down working pose which is extremely harmful to an organism is meant.
Monotonous load of a skeleton, joints and backbone leads to development of various diseases, in particular, of a chondrosis and osteochondrosis. Therefore the exhaustion of muscles during the statistical work differs from exhaustion at dynamic work. If after long sitting at the computer to rise and warm up, then it is possible to feel much better. Many note that it is better to move and perform various operations, than to be long in one pose. However, in a condition of dynamic work not only the condition of a muscular system, but also its coordination with other bodies and systems is of great importance.
Only the healthy and trained person is capable to work at high speed for a long time, involving at the same time the most part of the muscles which are available for it. And depending on quantity put into muscle work distinguish local, regional and general work.
