総説Literature Review 骨格筋減少症といわれるサルコペニアは高齢者の虚弱発生の主要な原因であり，老年医学及びリハビリテーションの観点からも重要な課題とされている．近年，国内外問わずサルコペニアに関する知見(判断基準，分類，メカニズム，治療など)が多数報告されている．その中でサルコペニアと栄養との関連性を指摘しているものがある．近年「栄養ケアなくしてリハなし」といわれ，低栄養状態が高齢者の生命予後やActivities of Daily Living（ADL）の悪化につながるとされており，栄養とリハビリテーションの関係が注目されている．本論文では，サルコペニアの概念・メカニズム・治療(栄養介入，運動介入)に関して述べ，さらに今後の課題として，トレーニング介入時の栄養状態に着目することの重要性に関して考察した．Sarcopenia, the loss of muscle mass and strength, is a common phenomenon in aging. It leads to functional limitations and the need for extended rehabilitation services. Malnutrition is also common across varying patient populations, particularly older adults, and sarcopenia prevalence increases with advancing age. Both malnutrition and sarcopenia are present in many patient populations and manifest clinically through a combination of decreased nutrient intake, decreased body weight, along with a decrease in muscle mass, strength, and physical function. Malnutrition and sarcopenia are also associated with increased morbidity, in particular increased infection and complications rates, including falls and disability. Rehabilitation nutrition care management is important to improve their activities of daily living and quality of life. This review article provides the concepts, mechanisms and treatments (nutrition interventions, exercise interventions) of sarcopenia, and discusses their importance, focusing on the nutritional status at the time of intervention
