The analyses were performed based on generalized linear models with generalized estimating equation. Turn time: the time of turning; TL: distance between the centers of pressure before and after turning; turn speed: the speed of turning; turn peak: the time to peak counteraction; turn force: peak counteraction of turning; turn force/weight: the ratio of peak counteraction of turning to body weight; turn peak/time: the ratio of turn peak to turn time; .
