Age features of O2 mass transfer regimes in adolescents’ body at rest

نویسندگان

چکیده

The results of complex studies the quantitative relationship between stage-by-stage mass transfer O2 and efficiency cardiorespiratory system functioning in relation to its consumption adolescents’ body under conditions relative rest are presented.
 obtained show that adolescents, modes nature respiratory circulatory systems have a number age-related differences compared with adult men. So, external respiration at functions less economically than adults. Each liter consumed by adolescents is extracted from almost 3 liters more adults amount air ventilated per minute through lungs. volumetric indicators blood circulation also higher which may indicate influence neuro-humoral rearrangements during pubertal period. coefficient oxygen utilization tissues arterial turned out be significantly higher, characterize tension tissue metabolic processes.
