A scoping review has been conducted on the prevalence and causes of hospitalization-related sarcopenia. Various studies have also investigated the relationship between sarcopenia and different health conditions, such as heart failure, pulmonary hypertension, and malnutrition, as well as the effectiveness of resistance training in managing the condition. The research appears to be exploring the complexities of sarcopenia, its associations with other health issues, and potential interventions to improve muscle health.
