Physical fitness concerns a set of attributes related to the ability to perform physical activity that may justify the symptoms reported by the elderly in the context of sarcopenia.
This study aimed to investigate the relationship between the perception (symptomatology) of physical functioning (what the person thinks they are capable of) and the capacity itself for physical functioning in elderly people in northern Brazil.
Cross-sectional study that analyzed 312 elderly people (72.6 ± 7.8 years) from the city of Novo Aripuanã, Amazonas, Brazil. Sarcopenia symptomatology was assessed using the SARC-F, a 5-item questionnaire designed for screening sarcopenia in older individuals in five domains: strength, walking aids, difficulty getting up from a chair, difficulty climbing stairs, and falls. Physical fitness was assessed by the Senior Fitness Test (SFT) battery including balance evaluated with the short version of the Fullerton Advanced Balance scale (FAB).
ROC curve analysis revealed that the tests with the greatest ability to discriminate participants with significant symptoms for sarcopenia (≥4 points on SARC-F) were arm curl and 6 min walk: the probability of suspected sarcopenia increased exponentially with an arm curl < 11.5 reps for men (se = 71%; sp = 69%; AUC = 0.706, 95% CI: 0.612-0.788; = 0.013) and women (se = 81%; sp = 51%; AUC = 0.671, 95% CI: 0.601-0.735; ≤ 0.001) or with a 6-min walk <408.5 m for men (se = 71%; sp = 63%; AUC = 0.720, 95% CI: 0.628-0.690; = 0.001) and <366.0 m for women (se = 69%; sp = 58%; AUC = 0.692, 95% CI: 0.623-0.755; = 0.0001).
Physical fitness assessed through the senior fitness test, particularly the 30-s-arm curl test and the 6-min walk test, can discriminate for suspected symptoms of sarcopenia.
体能涉及与执行体力活动能力相关的一系列属性，这可能解释了老年人在肌少症背景下报告的症状。
本研究旨在探讨巴西亚马逊州诺沃阿里普安纳市老年人的体能感知（症状）与体能能力之间的关系。
本横断面研究分析了 312 名老年人（72.6 ± 7.8 岁）的资料，这些老年人来自巴西诺沃阿里普安纳市。使用肌少症症状评估工具（SARC-F）评估肌少症症状，这是一个用于筛查老年个体五个领域肌少症的 5 项问卷：力量、助行器、从椅子上站起来困难、爬楼梯困难和跌倒。体能通过老年人体能测试（SFT）电池进行评估，包括使用 Fullerton 高级平衡量表（FAB）短版评估平衡。
ROC 曲线分析显示，对具有显著肌少症症状（SARC-F≥4 分）的参与者具有最大区分能力的测试是手臂卷曲和 6 分钟步行：男性手臂卷曲<11.5 次（se = 71%；sp = 69%；AUC = 0.706，95%CI：0.612-0.788； = 0.013）和女性（se = 81%；sp = 51%；AUC = 0.671，95%CI：0.601-0.735； = 0.001）、或男性 6 分钟步行<408.5 m（se = 71%；sp = 63%；AUC = 0.720，95%CI：0.628-0.690； = 0.001）和女性<366.0 m（se = 69%；sp = 58%；AUC = 0.692，95%CI：0.623-0.755； = 0.0001）的可能性呈指数级增加。
通过老年人体能测试评估的体能，特别是 30 秒手臂卷曲测试和 6 分钟步行测试，可以区分疑似肌少症症状。
