虽然坐-站（STS）测试作为下肢力量测量的有效性受到质疑，但它在老年人中广泛使用。本研究的目的是：1）描述青少年和成人的五次重复STS测试（FRSTST）性能（时间）; 2）确定等长膝关节伸展强度（力和扭矩）、年龄、性别、体重和身高与该性能的关系。参与者为111名女性和70名男性（14-85岁）社区居民，参加了NIH神经和行为功能评估。使用标准无扶手椅进行FRSTST。使用带稳定的手持式测力计测量膝关节伸展力;使用Biodex测力计测量膝关节伸展扭矩。FRSTST的平均时间范围为6.0秒（20-29岁）至10.8秒（80-85岁）。对于整个样本和50-85岁参与者的子样本，膝关节伸展强度（r =-0.388至-0.634），年龄（r = 0.561和0.466）和性别（r = 0.182和0.276）与FRSTST时间显著相关。在所有多元回归模型中，膝关节伸展强度提供了FRSTST性能的最佳解释，但年龄也有贡献。体重和身高在解释FRSTST性能方面不太一致。性别没有增加对FRSTST性能的解释。因此，我们的研究结果表明，FRSTST时间反映了下肢力量，但表现应根据年龄和其他因素进行解释。
Although the validity of the sit-to-stand (STS) test as a measure of lower limb strength has been questioned, it is widely used as such among older adults. The purposes of this study were: 1) to describe five-repetition STS test (FRSTST) performance (time) by adolescents and adults and 2) to determine the relationship of isometric knee extension strength (force and torque), age, gender, weight, and stature with that performance. Participants were 111 female and 70 male (14–85 years) community-dwelling enrollees in the NIH Toolbox Assessment of Neurological and Behavioral Function. The FRSTST was conducted using a standard armless chair. Knee extension force was measured using a belt-stabilized hand-held dynamometer; knee extension torque was measured using a Biodex dynamometer. The mean times for the FRSTST ranged from 6.0 sec (20–29 years) to 10.8 sec (80–85 years). For both the entire sample and a sub-sample of participants 50–85 years, knee extension strength (r = −0.388 to −0.634), age (r = 0.561 and 0.466), and gender (r = 0.182 and 0.276) were correlated significantly with FRSTST times. In all multiple regression models, knee extension strength provided the best explanation of FRSTST performance, but age contributed as well. Bodyweight and stature were less consistent in explaining FRSTST performance. Gender did not add to the explanation of FRSTST performance. Our findings suggest, therefore, that FRSTST time reflects lower limb strength, but that performance should be interpreted in light of age and other factors.
