Comparison between regional level (REG) and national level (NAT) groups of skiers performing postural tests with eyes open (EO) or closed (EC) in the SKI condition
| Posture | Group | Vision | S (mm2) | V (mm s−1) |
|---|---|---|---|---|
| Values are mean±SD in the STA, ML, and AP postures. S, surface of the COP; V, COP velocity. | ||||
