Effect of swimming on forced expiration and sputum clearance in cystic fibrosis

M S Zach et al. Lancet. .

Abstract

Ten children with cystic fibrosis participated in swimming training over 7 weeks. Ventilatory status, assessed by spirometry, had improved significantly after the course. 10 weeks after the end of the training most measurements had returned to their preswimming levels. In the majority of the children sputum production on swimming days was higher than on nonswimming days. Regular swimming can assist in mucus clearance and improve ventilatory function in children with cystic fibrosis.
