Resum
Introduction: Lung diffusion capacity of carbon monoxide (DLCO) provides a measure of gas transfer in the lungs, which increase in relation to exercise and decrease in the presence of lung interstitial disease. The aim of this study is to evaluate the changes in lung diffusion after anaerobic and aerobic exercise in a cycle ergometer. Material and method: The participants were 11 healthy active subjects, including 8 females and 3 males (age: 24.3 ± 3.1 years). Lung diffusion capacity for carbon monoxide (DLCO) was studied under two different protocols: In the first day, DLCO was measured at SL at rest (SL-R), after 30-s maximal exercise (SL-ANA), and after 15-min moderate continuous exercise (SL-AER). In the second day, DLCO was evaluated at rest at SL, and then at HA (4,000 m) at rest (HA-R) and after 30-min of moderate interval exercise (HA-AER). Results: There was an increase in DLCO from rest to after SL-ANA (32.5 ± 6.4 to 40.3 ± 11.6 mL·min-1·mmHg-1, P = 0.027). In the second day, DLCO was evaluated at rest at SL, and then at HA (4,000 m) at rest (HA-R) and after 30-min of moderate interval exercise (HA-AER). During HA exposure, there was no changes in DLCO, either at HA-R, or after HA-AER. Conclusions: Lung diffusion capacity largely increased after 30-s maximal exercise in a cycle ergometer, although the O2 -dependence is small during this type of anaerobic exercise. Thus, exercise intensity may be a key modulator of the changes in lung diffusing capacity in relation to exercise.
