Oxygen transport system during exhaustive exercise in Japanese boys.
The study was designed to investigate the age-related increase in maximal oxygen uptake with special reference to the other physiological parameters (ventilation, pulmonary diffusing capacity, cardiac output etc.). 77 normal boys aged 10-18 years were tested by the progressive loading method on a bicycle ergometer. VO2 max increased by approximately 55% with the age from 10-18 years. The increase in VO2 max was accompanied with increase in ventilation (49%), pulmonary diffusing capacity (45%) and cardiac output (5%).
