METHODOLOGY task condition.

Twenty-four recreationally active individuals were recruited to perform SDLs
under 4 conditions: simple SDL (CON), ankle taped (AT), dual-tasking (DT), and
ankle taped with dual-tasking (ATDT). Ankle rigid tape was used in the AT and
ATDT conditions, and the Stroop Colour Word Test (SCWT) was used in the DT
and ATDT conditions. Joint kinematics and kinetics were captured by inertial
measurement units (IMUs) and a force plate, respectively, at initial contact
(IC) and maximum value (MAX) during the landing phase. Two-way repeated-
measures ANOVA was used to analyse the interaction effects of taping and
dual-tasking, with a significance level of p < 0.05.
