In this issue of Chest (see page 463) de Jong and colleagues report in succession the benefits of a hearth exercise training program for patients with cystic fibrosis (CF) In their investigation ten adolescents and young adults with cystic fibrosis participated in a 3-month bicycle training program at abiding-place supervised 2 times per week from an investigator. After 3 month exposes showed increased maximal work capacity, maximal oxygen consumption, and anaerobic opening These CF patients then exercised without supervision for a fourth month and continued to point out benefits. The authors point to this meditation as a demonstration that an unsupervised to one's home exercise training program is feasible in CF patients, and might be beneficial.

In this investigation de Jong and colleagues directly supervised exercise training sessions in the to one's home two times per week, on the other hand they do not state in what manner many additional days per week the CF patients exercised at domestic circle A cynical view of this studious mood would be that two exercise sessions for week are enough to yield a physiologic exercise training answer Many other studies have demonstrated benefits from a supervised exercise training program in CF patients.[1-3] It assumes clear that CF patients can oftentimes benefit if they perform sufficient exercise training. In supervised settings, this on a level of participation can be assured. In the domestic circle study of de Jong et al, compliance may have been enhanced by way of the twice weekly visits of an investigator. In the absence of so supervision, one must rely forward the patient's own motivation to achieve adequate compliance in the home

de Jong and coworkers do not address in what manner to enhance compliance with an unsupervised exercise training program at domicile Compliance may be sufficient if the patient is motivated according to the benefit received from exercise, and if the exercise itself is interesting, or at least not unpleasant.

de Jong and colleagues make the important observation that their exercise training program improved CF patient's abilities to perform activities of daily living. This may be an important motivation for patients with chaste lung disease who may have substantial limitation in ability to perform activities of daily living. To this fall of the curtain improvement in the ability to perform submaximal exercise may be more important than increasing the maximal oxygen consumption. The make liables in the study of de Jong et al increased their anaerobic entrance suggesting that their endurance for exercise at of the same heights which may be required for activities of daily living was increased.

The place of abode exercise training study reported by dint of de Jong and colleagues is an important gradation which helps to establish that it is possible to motivate CF patients to participate in a long-term exercise training program at abode Although many believe that encouraging exercise programs for chronic lung disease patients will be beneficial to their health, several questions remain unanswered. Does regular exercise improve the health or survival of chronic lung disease patients? Are the forces of exercise training equally beneficial to patients with mild v bitter lung disease? Is exercise evermore harmful for patients with lung disease? Answers to these questions may help us determine the importance of encouraging exercise training for patients with chronic lung disease. If exercise is ultimately proven to be beneficial, then de Jong and his colleagues have shown us that these programs can be fortunately instituted in the patient's home
