Why the study?
The impact of obesity on cardiopulmonary response to exercise in patients with chronic post-COVID-19 syndrome needed to be analyzed.
Does obesity worsen cardiopulmonary response to exercise in patients with chronic post-COVID-19 syndrome?
Does obesity worsen cardiopulmonary response to exercise in patients with chronic post-COVID-19 syndrome?
Obesity is associated with worse cardiopulmonary exercise capacity and impaired gas exchange in patients with long COVID-19.

Obesity may impair exercise capacity in post-COVID syndrome; leaves open whether weight management alters outcomes.
Aim: To analyze the impact of obesity on cardiopulmonary response to exercise in people with chronic post-COVID-19 syndrome. Patients & methods: Consecutive subjects with chronic post-COVID syndrome 6 months after nonsevere acute infection were included. All patients received a complete clinical evaluation, lung function tests and cardiopulmonary exercise testing. A total of 51 consecutive patients diagnosed with chronic post-COVID-19 were enrolled in this study. Results: More than half of patients with chronic post-COVID-19 had a significant alteration in aerobic exercise capacity (VO2peak) 6 months after hospital discharge. Obese long-COVID-19 patients also displayed a marked reduction of oxygen pulse (O2pulse). Conclusion: Obese patients were more prone to have pathological pulmonary limitation and pulmonary gas exchange impairment to exercise compared with nonobese COVID-19 patients.
