    Abstract:
    Identifying performance variables associated with visual impairment classification in para-cycling is one of the steps to improve the evidence-based classification system, and consequently, bring equality in Paralympic sports. Thus, this retrospective study aimed to analyze a 1-km tandem-track race performance among para-cyclists (male and female) with different visual impairment degrees (B1, B2, and B3) and to verify the retrospective performance over 20 yrs in all sport classes. The data were extracted from 427 para-cyclists (251 male and 176 female) who competed in the Para-Cycling World Championships and Paralympic Games. The following performance variables were analyzed: time trial, velocity, pace strategies, and number of medals. A one-way analysis of variance was used to compare performance variables among athletes of different sport classes (B1, B2, and B3) and χ2 tests were implemented to test the association between sport classes and medal distribution with a level of significance set at a P value of less than 0.05. The main results revealed that partially sighted athletes exhibited better tandem-track race performance compared with blind athletes (P < 0.05). Significant associations between sport classes and medal distribution in male (P = 0.026) and female (P = 0.017) athletes were found (higher in B3 athletes). Only 23.2% of male and 41.5% of female B3 athletes were medalists, and B3 athletes performed better specifically compared with B1 in most race distances. Finally, B2 and B3 athletes showed higher performance improvements than B1 throughout 20 yrs in the male group. It was concluded that male and female visual impairment athletes who classified as B1 displayed lower tandem-track race performance and medal frequency compared with partially sighted athletes, mainly considering those in the B3 class. The competitive system for athletes with visual impairment should be improved to provide more equity in the track para-cycling events.
