Oxygen uptake at the beginning of work

Oxygen uptake at the beginning of work in U.S.A. Oxygen uptake at the beginning of work F. N. CRAIG Biomedical Labaratory, Edgewood Arsenal, Maryl of work. J. Appl. 1972 .-Four men performed treadmill exercise at oxygen costs of from 29 to 123 ml/kg per min. Oxygen uptake was measured at intervals of 15 s. Changes in oxygen CRAIG, F. N. Oxygen Physiol. 33(5): 61 l-615. uptake at the beginning uptake over the first 1.5 min were characterized by the slope of the regression of the logarithm of oxygen lag (cost minus observed uptake) on time. At costs above 60 ml/kg per min the slope decreased slightly; below 60, the slope increased as the cost declined. At the lower costs, slopes for the lags in ventilation heart rate changed in the same direction as those for oxygen uptake. The changes in slope of oxygen lag, although unexplained, are inconsistent with theories of the influence of anaerobic processes on oxygen uptake requiring strict applicability of first-order kinetics. The parallel changes in slope of their lags emphasize the interdependence of oxygen uptake, ventilation, heart rate. However, the restriction of ventilation by an added inspiratory resistance did not affect the slope of oxygen lag.
