OBJECTIVES
Sarcopenia is a skeletal muscle mass (SMM) disease characterized by loss of strength with generalized loss of SMM. The aim of this study is to evaluate the effects of a 12-week intervention on SMM, strength, and functionally in older adults.
METHODS
This is a retrospective analysis of an intervention protocol with older adults at risk of sarcopenia who performed a daily intake of oral nutritional supplements (ONS) and resistance training exercise (RET), 3 times a week. Calf circumference (CC), bioelectrical impedance analysis (BIA), handgrip strength (HGS) and Timed Up and Go (TUG) were performed at baseline and at 12 weeks.
RESULTS
Fifty-one older adults were included. The mean age was 76.3 ± 8.3 years and 68.6% were women. After 12 weeks, the study showed an increase of CC in cm (1.9 ± 2.5, p < 0.001), increase of strength in kg (5.4 ± 2.1, p < 0.001), reduction of TUG in seconds (-2.4 ± 4.8, p = 0.001), increase of free-fat mass in kg (1.0 ± 1.3, p < 0.001) and SMM in kg (0.9 ± 0.5, p < 0.001).
CONCLUSIONS
Nutritional intervention with ONS associated with RET, can increase muscle strength, SMM and functionality among older adults at risk for sarcopenia.
目的
肌肉减少症是一种骨骼肌质量（SMM）疾病，其特征是力量丧失并伴有SMM普遍减少。本研究的目的是评估一项为期12周的干预措施对老年人SMM、力量和功能的影响。
方法
这是一项对有肌肉减少症风险的老年人干预方案的回顾性分析，这些老年人每天摄入口服营养补充剂（ONS）并进行每周3次的抗阻训练运动（RET）。在基线和12周时测量小腿围（CC）、生物电阻抗分析（BIA）、握力（HGS）和计时起立行走测试（TUG）。
结果
纳入了51名老年人。平均年龄为76.3±8.3岁，68.6%为女性。12周后，研究显示CC增加了厘米数（1.9±2.5，p<0.001），力量增加了千克数（5.4±2.1，p<0.001），TUG减少了秒数（-2.4±4.8，p=0.001），游离脂肪量增加了千克数（1.0±1.3，p<0.001），SMM增加了千克数（0.9±0.5，p<0.001）。
结论
ONS营养干预联合RET可以增加有肌肉减少症风险的老年人的肌肉力量、SMM和功能。
