Coronavirus disease-19 (COVID-19) is a rapidly transmissible and infectious disease, which often leads to long COVID-19 syndrome. Physical exercise performed in the rehabilitation of patients with long COVID-19 has a positive impact on the long-term complications of the disease that reduce daily productivity (chronic fatigue, shortness of breath, attention disorders, anxiety, depression, etc.). The aim of master thesis was to systematically review scientific literature to present the effects of long COVID-19 on the physical performance of patients, analyze the current exercise interventions, and prepare a structured exercise rehabilitation for patients with long COVID-19. In the systematic review of professional literature, we focused on randomized controlled studies, which we searched for using a predefined search string for long COVID-19 syndrome (»long COVID-19«, »post-COVID-19«, »long-haul COVID-19«, etc.) and types of exercise rehabilitation (»exercise training«, »aerobic exercise«, »resistance training«, »rehabilitation«, etc.). The search string was used in six search databases and one registry. Out of 3835 results, we included 8 studies in the review that met our criteria. The quality of the studies was assessed using the TESTEX scale. The evaluation results described the adequate quality of the selected studies (an average of 10.37 out of 15 possible points), with the main shortcomings occurring in participant blinding, assessor blinding, and control group supervision. The observed intervention programs for the rehabilitation of patients with long COVID-19 included various types of exercises (strength training, aerobic training, flexibility training, relaxation, etc.) and their combinations, which positively impact the improvement of aerobic capacity, muscle strength, and quality of life of the patients and favorably reduce shortness of breath, fatigue, anxiety, and depression. Given the rather narrow selection of studies on the issue, we would like to highlight the need for further high-quality randomized controlled studies that would include more varied exercise methods for people dealing with the consequences of the COVID-19 pandemic in their interventions.
