the Maximum physical activity. Increasing step loading

you in section: the Maximum physical activity

I.K.Shhvatsabaja (1975) and other authors have noticed high correlation of ischemic changes on the electrocardiogram which has been removed during physical activity, with intensity of defeat by an atherosclerosis of the coronal arteries, revealed angiograficheski that testifies to the big diagnostic value of this method of research. The electrocardiogram-research with use of is functional-loading tests at healthy faces with risk factors gives the chance to reveal initial and latent forms IBS. The method of research with physical activity application should get out depending on conditions and medical institution possibilities. From loading tests are more often used mid-flight, the step-test, ' to sit down-rise ', veloergometricheskaja, test on tredmille, etc.

In the conditions of polyclinic for mass inspections mid-flight test and the step-test with the submaximum loading are used. The submaximum loading is the greatest for the given person the loading which is not causing signs of inadequacy; intensity makes it 75% of as much as possible admissible activity serdechnososudistoj systems.

The Maximum physical activity - loading at which the further strengthening of intensity of activity of cardiovascular system is not accompanied by increase in consumption of oxygen organism fabrics.

In practical work three principal views of physical activities - unitary, faltering and continuous with increasing intensity are used. Increasing step loading is more informative test, than loading with the constant set intensity.
