■肌肉减少症是一种骨骼肌质量(SMM)疾病,其特征是力量丧失和SMM的广泛性丧失。这项研究的目的是评估12周干预对SMM的影响,力量,以及在老年人中的功能。
这是对有肌肉减少症风险的老年人的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)和阻力训练(RET),一周三次。小腿周长(CC),生物电阻抗分析(BIA)在基线和12周时进行握力(HGS)和定时向上(TUG)。
■包括51名老年人。平均年龄为76.3±8.3岁,女性占68.6%。12周后,研究表明,CC以cm为单位增加(1.9±2.5,p<0.001),强度增加(5.4±2.1,p<0.001),以秒为单位的TUG减少(-2.4±4.8,p=0.001),以kg为单位的游离脂肪质量增加(1.0±1.3,p<0.001),以kg为单位的SMM增加(0.9±0.5,p<0.001)。
■与RET相关的ONS营养干预,可以增加肌肉力量,有肌肉减少症风险的老年人的SMM和功能。
UNASSIGNED: 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.
UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: Nutritional intervention with ONS associated with RET, can increase muscle strength, SMM and functionality among older adults at risk for sarcopenia.
