Brief Summary

The current Coronavirus Disease 2019 (COVID-19) pandemic is the most severe health crisis of the 21st century. This is not only due to the deaths caused by the disease. People that were affected by COVID-19 and supposedly recovered may suffer from long lasting sequelae. The presence of symptoms longer than 3 months after the infection with the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is referred to as Post-COVID-19 Syndrome or Long COVID-19. It is estimated that 10-20 percent of all infected people are affected. The most common symptoms include persistent fatigue, reduced physical capacity, dyspnoea, ageusia, anosmia, musculoskeletal pain and neuropsychological complaints such as depression, anxiety, insomnia and a loss of concentration.

Considering the novelty of the pathology, evidence on the successful treatment of Post-COVID/Long-COVID is scarce. Physical activity has been established as a treatment option for chronic diseases that have similar symptomatic manifestations to those of Post-COVID/Long-COVID. For example, exercise therapy has shown positive effects on the health status of patients with lung disease, depression, anxiety, insomnia and cognitive impairment. However, there has been controversy whether so-called Graded Exercise Therapy (GET) is a safe treatment strategy for patients with Chronic Fatigue Syndrome (CFS). This population may experience Post Exertional Malaise (PEM), a worsening of symptoms after physical, cognitive or emotional exertion. Since COVID-19 might be an infectious trigger for CFS, particular caution has to be taken when recruiting participants and when screening them for adverse events and worsening of symptoms during an exercise intervention.

It can be hypothesized that patients suffering from Post-COVID/Long-COVID can benefit from exercise in various ways, guaranteed that there is sufficient screening for PEM before and during the intervention and training volume and intensity are increased slowly and progressively.

The current study investigates the effects of a home-based concurrent training program on various parameters in people affected by Long COVID.

Study Groups

Home-based concurrent training

Combination of resistance training (5 exercises with bodyweight and/or resistance bands; 3 sets per exercise, 15-20 repetitions) and endurance training (mode of choice, light to moderate intensities which are monitored via heartrate zones, 20-40min per sessions); 3 weekly sessions on non-consecutive days

Group Type: EXPERIMENTAL

home-based concurrent exercise

Intervention Type: OTHER

3 weekly sessions of home-based concurrent exercise on non-consecutive days. Resistance exercise is comprised of lunges, hip thrusts, pushups, resistance band rows, core and performed for 3 sets with 15-20 repetitions at an RPE of 14-18 (6-20 BORG scale). Endurance exercise can be done by the mode of choice and is monitored by heartrate zones. Sessions are of low to moderate intensity (below VT2) and the duration will be slowly increased for 20-40min.
