Yang Chun-rong · Shenyang Tiyu Xueyuan xuebao · 2007
Two digital video cameras and the Novel Pedar-X insole system was used to record the plantar forces and moving pictures of sixteen experienced Tai Chi practitioners during the execution of Tai Chi movements and during normal walking.The one-leg stance duration during the one-leg stance were compared.The result showed that the percentage(standardized value) of the total duration spent in the one-leg stance was less(p0.05),the duration of each one-leg stance was longer(p0.01) in Tai Chi exercise then normal walking;Tai Chi exercise can improve the balance control during the one-leg stance.The ground reaction forces varied between the Tai Chi movements and normal walking.The ground reaction forces in Tai Chi are smaller then in normal walking.
