Lower-body power measured by a linear position transducer during the sit-to-stand (STS) movement declines with age and may be a predictor of physical disability in older adults. The purpose of this study was to establish normative data for STS power across the lifespan and to determine if differences exist between age cohorts, sexes, and age cohort-sex subgroups. Adults (N = 557) aged 18-89 were divided into five age cohorts and performed the STS connected to a linear position transducer, which calculated power and velocity during the movement. Significantly lower (p < .01) velocity was observed in a younger age cohort in females than males, whereas males saw a significant average power decrement (p < .01) in a younger age cohort than females. STS power norms give clinicians a metric predicting physical disability and may be of particular interest to males as their power production begins to decline at an earlier age.
在从坐姿到站姿（STS）动作过程中，通过线性位置传感器测量的下半身力量会随着年龄增长而下降，并且可能是老年人身体残疾的一个预测指标。本研究的目的是建立全生命周期内STS力量的规范数据，并确定不同年龄组、性别以及年龄组-性别亚组之间是否存在差异。18至89岁的成年人（N = 557）被分为五个年龄组，并进行与线性位置传感器相连的STS动作，该传感器会计算动作过程中的力量和速度。在较年轻年龄组中，观察到女性的速度显著低于男性（p <.01），而男性在较年轻年龄组中的平均力量下降幅度显著大于女性（p <.01）。STS力量规范为临床医生提供了一个预测身体残疾的指标，并且可能对男性特别有意义，因为他们的力量产生在较早年龄就开始下降。
