Melnyk S. Functional State and Adaptive Possibilities of Radioactive Polluted Area Resident Adolescents

Complex study of cardiovascular, respiratory and neuromuscular systems of radioactive polluted area (168 persons) and natural background radiation area resident adolescents (116 persons) was held. Superfluous increase of bioelectrical activity during rest and during reflectory muscles activation, wave amplitude decrease during maximum contruction, bioelectrical response adequacy index increase, disorders in reciprocal relations of antagonistic muscles interactions, more long latent period of sensomotor reactivity were registered in conditions of muscles physical endurance and physical efficiency decrease in radiation control area adolescents. Decrease of cardiovascular system functional possibilities in relation to physical exercise in radiation control area was determined, such as inadequate arterial average dynamic pressure decrease and minor periphery resistance drop in precapillary. Decrease of external respiration actual value in radioactive polluted area resident adolescents resulted into physical efficiency and bioelectrical muscle activity decrease.
