Center of pressure (CoP) measures (mean±s.d.) for all phases of the experiment.

CoP excursion ranges in the anterior-posterior (AP) and medio-lateral (ML) directions for the early and late phases during the null, jump-0, jump-b, jump-f, and post blocks. Early consisted of the first 15 successful trials and late were the last 15 successful trials.□Subjects had different target distances.na = not applicable. Response times only calculated when subjects were forced to make a maneuver during the backwards target-jump.Bold text highlights planned comparisons.*Significantly different, p
