The impact of sedentary lifestyles and physical activity on post-COVID syndrome: Adipose tissue and immune system interactions

Abstract

Research indicates that a sedentary lifestyle significantly contributes to the development of post-COVID syndrome (PCS), characterized by persistent symptoms following acute COVID-19 infection. Engaging in regular physical activity is essential not only for mitigating these risks but also for enhancing recovery from COVID-19. Studies have shown that individuals who maintained high levels of PA before and after infection experienced fewer and less severe symptoms associated with PCS. Specifically, exercise training has been identified as a critical intervention for improving muscle function and modulating adipokine levels—signaling proteins released by adipose tissue that play a role in inflammation and metabolic regulation. Given the complex pathogenesis of PCS, which involves various physiological and psychological factors, it is imperative to incorporate structured exercise regimens into rehabilitation programs for affected individuals. Aerobic endurance training has demonstrated significant benefits in improving exercise capacity, reducing fatigue, and enhancing overall quality of life in PCS patients. Furthermore, high levels of PA are associated with improved immune function and lower rates of reinfection. In conclusion, promoting mandatory physical activity during and after pandemic conditions is vital for reducing the burden of post-COVID syndrome and enhancing public health outcomes. This review underscores the necessity for healthcare providers to advocate for exercise as a primary strategy in managing post-COVID symptoms and preventing future chronic diseases linked to sedentary behavior during different pandemics.
