Nutritional, musculoskeletal, and/or ventilatory status can lead to a decreased
exercise capacity in children with cystic fibrosis (CF). Exercise training is
already part of the usual care; however, the "optimal" intensity and volume of
exercise training to improve exercise capacity is still unknown. Six weeks of
high-intensity interval training (HIT) for a patient with CF with a ventilatory
limitation was evaluated by a cardiopulmonary exercise test (CPET). Peak oxygen
uptake and peak workload increased 19% and 16%, respectively, and there was a
rise in peak ventilation from 50 L/min to 75 L/min, with an increase in both
breathing depth and respiratory rate. A relative short period of HIT resulted in
a significant increase in exercise capacity. In patients with CF, HIT might be an
effective and efficient training regimen, especially in CF patients with a
ventilatory limitation. Further research is necessary to investigate whether HIT
is a better alternative than traditional aerobic training programs especially in
ventilatory limited patients with CF.
