坐立（STS）运动的三个关键点被确认为地面反作用力（GRF）的方面：开始，最大GRF和座位脱落。46名健康受试者（M年龄= 22.2岁，SD = 4.4）参与研究。在STS运动过程中，使用两个垂直力平台测量产生的GRF，定义为全身力，以及它的两个组成部分，臀部和腿部GRF。组成GRF的开始比合成GRF的开始更准确地确定了STS运动中重要时间点的顺序。数据显示，全身最大GRF、双腿最大GRF和脱座是依次出现的，而不是同时出现的。
Three key points of the sit-to-stand (STS) movement were confirmed as aspects of the ground reaction force (GRF): the onset, maximum GRF, and seat-off. 46 healthy subjects (M age = 22.2 yr. SD = 4.4) participated. During the STS movement, two vertical force platforms were used to measure the resultant GRF, defined as the whole-body force, and its two components, the buttock and leg GRFs. The onsets of the component GRFs identified the sequence of the important time points in the STS movement more precisely than the onset of the resultant GRF. Data showed that the maximum whole-body GRF, the maximum GRF of both legs, and seat-off appeared in sequence and not simultaneously.
