Stabilization Capacity. Changes in capability to restabilze a sudden pertubation of the underground (a) stabilization capacity medio-lateral (m-l), (b) stabilization capacity anterior-posterior (a-p)). Data are mean ± 1 SE for the three experimental groups (light circle = 2 weekly sessions, grey triangle = 4 weekly sessions, black sqaure = 6 weekly sessions). * P ≤ 0.05 vs. pre, † P ≤ 0.05 vs. mid
