Our work aimed to find out whether Tai Chi (TC) exercise could improve body stability among the elderly under a physical-cognitive dual task (DT) condition during stair ascent. 15 elderly persons who regularly exercised TC and 15 no exercise (NE) participants were asked to walk ascending stairs under single task (ST) and DT conditions in this study. The results showed the TC group had a lower lateral impulse and center of mass-center of pressure (COM-COP) ap/ml separation under the DT condition; Compared with the ST condition, the TC group increased foot clearance, the NE group increased their lateral impulse and COM-COP ml separation under the DT condition. Under DT, body stability decreased among the NE group, but the TC group had better body stability during stair ascent under both ST and DT conditions.
