COVID-19, Endurance, Exercise Capacity, Fatigue



While many researchers have investigated the influence of COVID-19 on fatigue and quality of life, its impact on exercise capacity has been little considered. It is therefore our aim to examine the impact of COVID-19 on exercise capacity and fatigue among individuals who have recovered from the virus.


A cross-sectional study was conducted at the outpatient physical therapy department of a tertiary hospital and Primary health care center. The study comprised 116 participants divided into two groups: a normative group composed of individuals who had not been infected with COVID-19 in the past three months, and a control group consisting of those who had contracted COVID-19 within the preceding three months. The one-minute sit-to-stand test (1STST) was carried out to assess exercise capacity, following which fatigue was measured using the validated Arabic version of the Fatigue Severity Scale (FSS).


Of the 116 participants enrolled in this study, 76 (65.5%) were in the normative group and 40 (34.5%) in the control group. Following the intervention, the mean FSS score differed significantly between the normative (26.6; SD 10.9) and the control group (36.9; SD 14.8); p-value < 0.001, with participants in the control group reporting higher levels of weariness than those in the normative group. Moreover, as measured by 1STST, the median number of sit-to-stand repetitions completed by participants in the normative group (21.0) was considerably greater than that of the control group (20.0); p-value = 0.025.


Participants in the control group reported higher levels of fatigue and demonstrated lower exercise capacity than those in the normative group.
