Multidisciplinary Combined Exercise and Nutrition Intervention for Sarcopenia

Effectiveness and Clinical Application of Multidisciplinary Combined Exercise and Nutrition Intervention for Sarcopenic Older Adults With Metabolic Syndrome: Multicenter Randomized Controlled Trial

This study aims to demonstrate the effect of combined exercise-nutrition intervention in old adults with sarcopenia. This study will be conducted with prospectively randomized controlled trial comparing outcome of combined exercise-nutrition intervention with conventional medical care. Handgrip strength, gait speed, knee extensor muscle power, physical performance, muscle mass using DEXA, quality of life, activities of daily living, sarcopenia screening questionnaire, nutritional assessment will be evaluated on baseline, 12-weeks and 24-weeks after intervention.

The definition of sarcopenia is age-related loss of skeletal muscle and physical functions. Sarcopenia is emerging health problem and increases medical expenditure as the population ages. Sarcopenia is closely related to chronic diseases and geriatric diseases. In particular, patients with metabolic syndrome showed a high prevalence of muscle loss and muscle weakness. It has been reported exercise in sarcopenia patients not only improved insulin sensitivity and physical performance but also helped the treatment of the diseases. Also, it is recently demonstrated that combined exercise-nutrition intervention improved muscle function in elderly patients. However, there is still not established standard protocol for the combined exercise-nutrition intervention. Therefore, the aim of this trial is to compare the effects of combined exercise-nutrition intervention in sarcopenia patients with multicenter, multidisciplinary, randomized controlled trial.
