Limitations
CORONAVIRUS
One of the limitations in this study was not comparing spirometry findings between COVID-19 patients and healthy individuals. Also, because of the coronavirus pandemic, access to a sufficient number of patients was difficult. However, we tried to select participants from both genders to diminish this problem. The lack of a follow-up procedure was the other limitation that could estimate the prolonged effects of the exercise program on patients. In addition, in the present study, like any other human research, the family environment and social and economic conditions of individuals can affect the results of the research. Therefore, the generalization of current results to the wider target population should be done cautiously.
