Mechanical work for step-to-step transitions is a major determinant of the metabolic cost of human walking

JM Donelan, R Kram, AD Kuo - Journal of experimental …, 2002 - journals.biologists.com
In the single stance phase of walking, center of mass motion resembles that of an inverted

The six determinants of gait and the inverted pendulum analogy: A dynamic walking perspective

AD Kuo - Human movement science, 2007 - Elsevier
We examine two prevailing, yet surprisingly contradictory, theories of human walking. The
six determinants of gait are kinematic features of gait proposed to minimize the energetic …

Energetic consequences of walking like an inverted pendulum: step-to-step transitions

AD Kuo, JM Donelan, A Ruina - Exercise and sport sciences …, 2005 - journals.lww.com
It costs several times the metabolic energy for a human to walk as it does to bicycle the same
distance. Walking is often likened to the motion of two coupled pendula, because the stance …

Energetics of actively powered locomotion using the simplest walking model

AD Kuo - J. Biomech. Eng., 2002 - asmedigitalcollection.asme.org
