“…Furthermore, it should be noted that the reference range for diaphragm thickness is influenced by factors such as age, BMI, and sex, making it necessary to consider individual characteristics [12]. CT images can evaluate respiratory muscle mass in the chest [13,14]. Respiratory muscles that can be evaluated with CT include the diaphragm [15], pectoralis muscle [16,17], erector spinae [18], iliopsoas, and the abdominal muscle groups.…”

Purpose of review Skeletal muscle weakness and wasting also occurs in the respiratory muscles, called respiratory sarcopenia. Respiratory sarcopenia may lead to worse clinical indicators and outcomes. We present a novel definition and diagnostic criteria for respiratory sarcopenia, summarize recent reports on the association between respiratory sarcopenia, physical and nutritional status, and clinical outcomes, and provide suggestions for the prevention and treatment of respiratory sarcopenia. Recent findings Recently, a novel definition and diagnostic criteria for respiratory sarcopenia have been prepared. Respiratory sarcopenia is defined as a condition in which there is both low respiratory muscle strength and low respiratory muscle mass. Respiratory muscle strength, respiratory muscle mass, and appendicular skeletal muscle mass are used to diagnose respiratory sarcopenia. Currently, it is challenging to definitively diagnose respiratory sarcopenia due to the difficulty in accurately determining low respiratory muscle mass. Decreased respiratory muscle strength and respiratory muscle mass are associated with lower physical and nutritional status and poorer clinical outcomes. Exercise interventions, especially respiratory muscle training, nutritional interventions, and their combinations may effectively treat respiratory sarcopenia. Preventive interventions for respiratory sarcopenia are unclear. Summary The novel definition and diagnostic criteria will contribute to promoting the assessment and intervention of respiratory sarcopenia.
