Exhaled nitric oxide decreases during exercise in non-asthmatic children
The Clinical Respiratory Journal, 04/27/2012
Evjenth B et al. – Exhaled nitric oxide (FENO) is reduced by 27.4% immediately after a standardized treadmill exercise test in non–asthmatic children. Pupils reporting allergic rhinoconjunctivitis (AR) symptoms demonstrate a larger decline in FENO value at 1 min post exercise compared to pupils without AR symptoms. These findings confirm that children should refrain from physical activity before FENO measurement.
