Normalized to body height centre of pressure mean velocities during 60 s of quiet standing in artistic (n = 10) and acrobatic (n = 10) gymnasts. Data shown as the means ± standard errors. Between group differences (Mann-Whitney U): p > 0.05; Between-session differences - EO vs. EC (Wilcoxon test): *p = 0.005, r ES = 0.63; **p = 0.009, r ES = 0.58; ***p = 0.04, r ES = 0.47; ****p = 0.047, r ES = 0.44. ARG – artistic gymnasts, ACG – acrobatic gymnasts; EO - eyes open, EC – eyes closed; AP – anterior-posterior plane, ML – medial-lateral plane.; r ES – effect size
