Abstract
This study compares the transient oxygen uptake, blood lactate (LA), and oxygen deficit at the onset of exercise in prepubertal boys and young adults. In boys, the increase of the oxygen uptake was faster, the blood LA lower, and the oxygen deficit smaller as compared to young adults. A procedure for the calculation of oxygen deficit is proposed. Significant correlations have been found between the percentage of oxygen uptake in the 1st halfminute of exercise vs initial oxygen deficit (r = -0.77) and the blood LA (r = -O.81) and between the initial oxygen deficit vs the blood LA (r = 0.69).
