Exhaled carbon monoxide (CO) as blood acidity marker in sportsmen

Abstract
Aim. Carboxyhemoglobin dissociation rate strongly depends on the blood acidity (Bohr's effect). Therefore, CO concentration in the exhaled air increases as a result of lactate production after highintensity exercise. We studied a relationship between CO concentration in the exhaled air and lactate concentration in the blood after highintensity exercise in athletes.
Methods. CO concentration was measured by Smokerlyzer® (Bedfont Scientific Ltd, GB) with previous breath hold; lactate concentration was measured by Accutrend® Lactate (Roche Diagnosics GmbH, Germany).
Results. Nine elite cyclists were involved, mean (± SD) age, 25.0 ± 2.8 years; mean height, 175.0 ± 4.5 cm; mean weight, 76.5 ± 5.8 kg; the maximal oxygen uptake, 65.6 ± 4.5 ml / min / kg before and after cyclerace training. CO concentration ratio was significantly related to lactate concentration. After the training, there were 3.5fold increase in lactate concentration (from 2 to 7 mmol / L) and 2.5fold increase in CO concentration (from 3 to 10 ppm).
Conclusion. Our findings provide a basis for development of novel noninvasive express methods for anaerobic threshold detection and could be useful in elite athletes training, fitness and aerobics.
