Abstract Aim: To assess the postural control performance of football 5-a-side (FFS) players, comparing them with sighted players. Methods: Eight FFS players and 7 sighted futsal players were included. Postural control tests included feet together stance (FTS) and single-leg stance (SLS) tasks, performed on rigid and foam surfaces. Sighted players performed the tests with open (EO) and closed (EC) eyes. Area of displacement (Area) and average velocity (Vavg) were calculated from the center of pressure time-series coordinates. Results: On both surfaces conditions, a significant difference between visually impaired football 5-a-side players and sighted EO players was observed during FTS (higher Vavg for visually impaired football 5-a-side players; p < 0.04) and SLS (higher Area and Vavg for visually impaired football 5-a-side players; p < 0.01). No differences between visually impaired football 5-a-side players and sighted EC players were found. Differences between sighted EO vs. sighted EC were observed during FTS on the foam surface, and in SLS on both surface conditions (p < 0.03). Conclusion: FFS players' postural control performance is similar to sighted players with EC but worse than sighted players with EO, suggesting their postural control performance can be simply explained in terms of visual restriction.
