營養對於肌少症老人之影響

Abstract

全球的平均餘命持續增長，世界各國都面臨人口老化的挑戰，其中肌少症是高齡社會需面臨的挑戰之一。肌少症定義為隨著年齡增長，肌肉量及身體功能大幅低下的症候群，亦是提高老年人失能、跌倒及死亡率的危險因子。本主題性統整報告目的在找出對於肌少症老人最適合的解決方法，提高老年人肌肉量及肌肉功能藉以降低肌少症所導致的影響。近期研究顯示高品質蛋白質補充加上適當運動訓練計畫可以增加肌少症老人的肌肉量及肌力。本主題性統整報告實行方式為設計並提出一個臨床試驗計畫，對於肌少症老人族群檢測蛋白質補充配合運動訓練在肌肉量及肌肉功能的改變。預期之試驗結果為配合蛋白質補充使用之老人比單純的運動訓練組有更多的肌肉量及肌肉增加。透過進一步研究清楚關於營養對肌少症老人的影響後，未來可以提出一個更容易可行的方式預防或延緩肌少症的發生及進程，並降低肌少症所帶來的個人、社會、經濟層面之負擔。

People worldwide are living longer. All countries face major challenges leading by aging and one of these challenges is sarcopenia. Sarcopenia, defined as the loss of skeletal muscle mass and physical function that occurs with aging, increased the risk of physical disabilities, falls and mortality in the elderly. The aim of this report is to figure out an ideal solution to improve body performance among elderly people with sarcopenia to decrease the impact of sarcopenia. Recent studies showed high-quality protein with exercise training may increase muscle mass and muscle strength in elderly people. The implementation was the proposal of a clinical trial to examine the effect of exercise and protein supplement on muscle mass and physical functions in elderly people with sarcopenia. The anticipated results were participants who will receive protein supplement will have extra muscle mass gain or further improvement on muscle strength compared with exercise alone group. By further researches about the influence of nutrition among elderly people with sarcopenia, people may conclude a readily available means to prevent the occurrence of sarcopenia, which is an increasing morbidity burden for a rapidly aging society and to decrease the personal, social and economic burdens due to sarcopenia.
