COVID-19 related to sarcopenia: Current perspectives on etiology, clinical implications, and nutritional rehabilitation

Sarcopenia is a progressive skeletal muscle disorder characterized by reduced strength and quality. Pathophysiological mechanisms, clinical aspects, nutritional points were related to sarcopenia in COVID-19 found during after the disease course, which corroborated development of adverse events. Declining physical activity, insufficient protein intake, worsened proinflammatory response have been shown negative consequences on synthesis, potentiating risk acute sarcopenia. Obesity has also worsen prognosis patients with SARS-CoV-2. Nutritional rehabilitation used prevent or minimize Dietary recommendations include increased energy supply intake 1.2 2.0 g/kg body weight. Evidence suggests that aging sedentary behaviors, pathophysiological changes, inflammation alter composition. In addition, deficiencies are predictors aggravators COVID-19.
