Previous investigators have reported the physiologic effects of walk/jog, bicycle ergometer, and swimming exercise training programs on children with cystic fibrosis. These investigators1-5 reported that exercise training programs are effective in improving the ability of a patient to clear accumulated lung mucus and increase the capacity to endure exercise before becoming dyspneic. The present treatment for individuals with cystic fibrosis includes a routine of physiotherapy to keep the lungs clear of mucus, a process which is vital to the health and well-being of a patient. These procedures, however, are very time-consuming a d may force a patient to plan his/her daily schedule around treatments.
It has also been observed that individuals with cystic fibrosis progressively restrict their physical activity because of increased wheezing and dyspnea. This inactivity may result in progressive muscle deterioration, increased shortness of breath, and a greater loss of exercise tolerance.6 The two potential
