Dynamic Principle of Center of Mass in Human Walking

Yifang Fan, Yubo Fan, Zhiyu Li, Mushtaq Loan & Changsheng Lv · Biotechnology Journal International · 2013

Assuming the ground reaction force of both feet to be the same in the same phase of a stride cycle, we establish the relationships between the time of initial foot contact and the ground reaction force, acceleration, velocity, displacement and average kinetic energy of center of...
