Change in telescoping leg strategy with varying walking speed to modulate force advantage.

摘要: Human walking consists of two major sequential events (i.e., single- and double-support phases). Although there have been many studies relating to basic principles the each stage, how distinct but continuous phases interact with other remains be clarified. We examined change in strategy varying speed on a local reference frame telescoping tangential axes; we expect that directional dynamics at end single-support phase facilitate modulation push-off work during phase. The force power are calculated using methods: model simulation kinematic configuration. empirical data for eight healthy young subjects corresponding parameters obtained from data-fit optimization were used investigate changing trend factor power) increase speed. resulting significantly increased both methods, whereas remained nearly unchanged was close zero entire range speeds. This result implies positive amount may certain type preparation phase, which can contribute larger push-off.
