为了检验仰卧起坐表现与肌肉减少症分类测量相关的假设，将93名年龄在53-78岁之间的老年女性根据仰卧起坐表现测试的重复次数（30秒）分为三组：g 0组（G 0，n = 33）进行0次重复，组1-9（G 1-9，n = 30）重复1 - 9次，组10+（G 10+，n = 30）重复10次以上。测量双能X线吸收测量法得出的四肢瘦软组织质量（aLM）、握力（HGS）、通常步行速度和椅子站立，并根据先前的研究定义低肌肉质量（aLM指数）和身体功能差。年龄和体重指数在三组之间相似。HGS在G10+中高于G 0。低肌肉质量的患病率为30%的G 0，20%的G 1-9，和3%的G 10+。在G 0（24%）和G1 -9（20%）中均观察到低HGS，但在G10+中未观察到。只有两个人在G 0被归类为缓慢的步行速度。我们的研究结果表明，仰卧起坐的表现可能是一个有用的指标，以确定肌肉减少症的程度，因为低肌肉质量和功能差几乎不存在的个人谁可以执行超过10个仰卧起坐。
To test the hypothesis that sit-up performance is associated with sarcopenia classification measures, 93 older women aged 53–78 years were divided into three groups based on achieved repetitions (30 s) for the sit-up performance test: Group 0 (G 0, n = 33) performed 0 repetitions, Group 1–9 (G 1–9, n = 30) performed between 1 and 9 repetitions, and Group 10+ (G 10+, n = 30) performed over 10 repetitions. Dual-energy X-ray absorptiometry-derived appendicular lean soft tissue mass (aLM), handgrip strength (HGS), usual walking speed, and chair stand were measured, and low muscle mass (aLM index) and poor physical function were defined according to previous studies. Age and body mass index were similar among the three groups. HGS was higher in G 10+ compared with G 0. The prevalence rate of low muscle mass was 30% for G 0, 20% for G 1–9, and 3% for G 10+. Low HGS was observed in both G 0 (24%) and G 1–9 (20%), but not in G 10+. Only two persons in G 0 were classified as slow walking speed. Our results suggest that sit-up performance may be a useful indicator to determine the extent of sarcopenia because low muscle mass and poor function were almost non-existent in individuals who could perform over 10 sit-ups.
