Exercise conditioning and cardiopulmonary fitness in cystic fibrosis. The effects of a three-month supervised running program.
Exercise intolerance is common in cystic fibrosis ( CF ) . We examined the effects of a supervised three-month running program on exercise tolerance , pulmonary function , cardiorespiratory fitness ( peak oxygen consumption ) , and respiratory muscle endurance in CF patients . We studied 31 patients , 21 exercise and ten control , aged 10 to 30 years , with pulmonary involvement ranging from mild to severe . The exercise and control groups were not significantly different with respect to age , sex , pulmonary function , exercise tolerance , or cardiorespiratory fitness . After three months of physical conditioning , the exercise group had significantly increased exercise tolerance and peak oxygen consumption and significantly lower heart rates for submaximal work loads , while the nonexercising ( control ) group was unchanged in all these variables . The FEV1 decreased significantly in the control group . There were no other significant changes in pulmonary function in either the control or exercise group . Respiratory muscle endurance increased significantly in the exercise patients , and did not change in the control patients . There were no adverse effects of the program . The data suggest that a supervised running program can increase CF patients '  exercise tolerance and cardiorespiratory fitness , perhaps in part by increasing respiratory muscle tolerance . The effects of a much longer program deserve study
