title: [On mechanism of functional changes in the organism of teenagers at different levels of locomotor activity].
abstract: Comprehensive study of the cardiovascular system functional condition of 15-16 teenagers while in normal daily locomotor activity and in the mode of regular moderate physical activity was performed. The features of cerebral circulation and myocardium functional condition of teenagers are studied depending on initial tonus of the autonomic nervous system and locomotor activity level in the process of continuous step physical activity on tredmil. The condition of regulatory mechanisms, providing adaptation of teenagers in the conditions of modern school was studied. Research results showed, that elasticity of cerebrum arterial vessels, veins tone, venous outflow for teenagers not having regular physical activity, considerably mionectic. More adequate reaction of coronary blood flow in the process of physical activity is educed for the trained teenagers with the balanced autonomic regulation of cardiac rhythm. This group showed a higher level and regulation quality of organism reserve possibilities.
