ABSTRACT Currently, all eligible goalball players compete together irrespective of their level of vision impairment, yet it remains unclear whether those with more impairment are disadvantaged during competition. Following the International Paralympic Committee’s requirement for evidence-based, sport-specific classification, this study assessed whether individual goalball performance relates to the level of visual impairment. Using results from the 2016 and 2020 Paralympic Games, players’ sport classes and in-competition key performance statistics (minutes played, throws per minute, goals per minute, penalties conceded per minute, blocks per minute, and goals per throw) were extracted. Players’ visual acuity and visual field results were obtained through the IBSA Sport Administration System. Results showed no statistically significant differences in performance between classes. Further, there were no significant relationships between vision and performance for all six variables for female players. A small but significant positive correlation was found between visual acuity and the number of penalties conceded for male players. Collectively, the results suggest that currently eligible players compete fairly against one another during competitive goalball matches. Results provide support for the existing system of classification whereby all eligible athletes compete against each other irrespective of their level of impairment.
