Effects of an intensive 4-week summer camp on cystic fibrosis: pulmonary function, exercise tolerance, and nutrition.

Study Objectives: Cystic fibrosis (CF) patients prefer exercise to most other forms of therapy, although objective improvement remains controversial. Israeli CF patients have attended a summer program in Switzerland for many years with subjective improvement. However, CF camps worldwide have been cancelled recently, due to fears of cross-infection with resistant organisms.
