Aim: The aim of this study is to verify if exist a postural balance difference among female and male skiers, testing them with and without ski boats on a stabilometric balance platform (1). Findings will permit to understand the higher rate of injuries in female amateur skiers than in male amateur skiers (2). Method: Thirty amateur skiers: 15 males (26 ± 2 years, 176 ± 34 cm height and 72 ± 20 kg weight) and 15 females (25 ± 2 years, 165 ± 34 cm height and 55 ± 7 kg weight) were tested using a stabilometric balance platform (Prokin PK 214) and a biaxial trunk accelerometer (TK – Trunk Sensor). They performed bipodalic (60 s) and monopodalic (30 s) trials in eyes open and eyes closed conditions with and without ski boats. Results: Findings highlight the best balance performances in female group both in bipodalic (p=0.05) and in monopodalic (p=0.05) trials, in upright stance with and without ski boats and visual feedback (p<0.05). Only in skier position with ski boats female group shows an increase in medium lateral movements and in anterior-posterior velocity of the CoP (p<0.05). Moreover, during monopodalic stance in skier position with ski boats, female group reveals an attitude in valgus position highlighted by the CoP displacement in their body medial side (p<0.01). Conclusion: This postural characteristic in female group could provoke a great difficulty in foot lateral inclination, that is an essential movement to bring the ski on its external edge. Considering that female group shows worst results only in skier position with ski boats, findings will have a crucial role answering to their highest rate of injuries in ski track. References: 1.

Abstract
Aim: The aim of this study is to verify if exist a postural balance difference among female and male skiers, testing them with and without ski boats on a stabilometric balance platform (1). Findings will permit to understand the higher rate of injuries in female amateur skiers than in male amateur skiers (2). Method: Thirty amateur skiers: 15 males (26 ± 2 years, 176 ± 34 cm height and 72 ± 20 kg weight) and 15 females (25 ± 2 years, 165 ± 34 cm height and 55 ± 7 kg weight) were tested using a stabilometric balance platform (Prokin PK 214) and a biaxial trunk accelerometer (TK – Trunk Sensor). They performed bipodalic (60 s) and monopodalic (30 s) trials in eyes open and eyes closed conditions with and without ski boats. Results: Findings highlight the best balance performances in female group both in bipodalic (p=0.05) and in monopodalic (p=0.05) trials, in upright stance with and without ski boats and visual feedback (p<0.05).
