The analyses were performed based on generalized linear models with generalized estimating equation. Back time: time of turning back; BL: length of turning back of center of pressure; back speed: the speed of turning back; Back peak: the time of peak counteraction from turning back; back force, peak counteraction of turning back; back force/weight: the ratio of peak counteraction of turning back to body weight. Back peak/time: the ratio of back peak to back time; .
