The aim of this study of to evaluate the test-retest reliability of single-breath lung diffusing capacity measurements for nitric oxide (DLNO) in healthy individuals during light and moderate intensity cycling exercise. Healthy subjects will perform repeated single-breath DLNO measurements during light (i.e., at 50% of the first ventilatory threshold) and moderate intensity exercise (i.e., 80% of the first ventilatory threshold) on a stationary cycle ergometer.
This study investigates the test-retest reliability of the lung diffusing capacity for nitric oxide in healthy individuals during exercise.
