“…[6][7][8] In VI judo, Kons et al 7 found that B1 athletes lose more matches and have a lower performance (e.g., scores and efficiency) than partially sighted athletes (B2 and B3) during official matches. Similar results were found for time-motion variables, 25 victories, and medals 6 over 10 yrs 8 in VI judo matches. In addition, a recent study identified that there is an inverse relationship between VI judo athletes' performance and visual acuity (r = −0.33), 26 highlighting that the ability to perceive contrast and motion could show strong associations with performance in vision sports, as judo.…”

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.

“…Few previous studies analyzed sports performance according to visual impairment classes. A recent study reported that B1 judokas are in a disadvantage in some performance parameters in comparison with B2 and B3 judokas (Gutiérrez-Santiago, Gutiérrez, & Prieto-Lage, 2020). Another study found mixed results in goalball, since B1 players had higher game performance in defense, while B2 and B3 players demonstrated higher efficiency in offensive actions (Bartosz et al, 2015).…”

Introduction: The Paralympic movement has grown considerably over the last decades, but few studies have analyzed the performance evolution of the best athletes with disabilities. This study examined the performance of athletes with visual impairments in track-and-field events over eight Paralympic Games (1988–2016). Method: Results in the Paralympic track-and-field events for athletes with visual impairments (and in the corresponding track-and-field Olympic events) were collected from official public websites. Results: Analysis showed that most performances at Paralympic track-and-field events increased linearly over the years, which finding contrasts with the general stagnation in Olympic events. The improvements from 1988 to 2016 in Paralympic sprinting, middle- and long-distance running, throwing, and long-jumping events were 4.0–16.3%, 3.2–16.2%, 23.0–54.2%, and 4.9–18.9%, respectively. Men had better performances than women in running, throwing, and jumping events. In general, sports classes with a less severe level of visual impairment achieved higher performance levels than those with a more severe level of visual impairment, especially men. The competition density of Paralympic track-and-field events showed modest improvements. Conclusions: This study provides evidence that the performance of track-and-field athletes with visual impairments have been improving persistently over the last eight Paralympic Games, confirming that Paralympic athletes are achieving high-level performances. Implications for Practitioners: This study will be helpful for coaches and athletes with visual impairments who are setting performance (and training) goals for the Paralympic Games and other international athletic events.

“…Sacrifice techniques are throws whereby the attacking judoka drops him/herself on his back first (i.e., "sacrifices" oneself) to execute the throw (Daigo, 2005). The time-motion analysis was based on the time that each action occurred during the match, expressed in seconds of playing time (Gutiérrez-Santiago et al, 2012, 2020.…”

In Paralympic judo for athletes with vision impairment (VI judo) all eligible athletes (i.e. B1, B2 and B3 classes) compete against each other in the same competition. Evidence suggests that athletes with more impairment may be disadvantaged, but that more sensitive measures of performance are necessary to understand the impact of impairment on performance. The aim of this study was to investigate the relationship between Para sport class and technical variation, time-motion variables, and performance in Paralympic judo. All 175 judo matches from the Rio 2016 Paralympic Games were analysed across 129 competitors (82 male and 47 female). The main results indicated that athletes who demonstrated less technical variation also experienced less competitive success, with the functionally blind athletes (class B1) demonstrating less technical variation than partially sighted (class B2 and B3) athletes (p < 0.05). There was no difference in the time-motion variables between sport classes (p > 0.05). We conclude that measures of technical variation are sensitive to differences in impairment and are suitable for studies that investigate the impairment-performance relationship in VI judo. Results further confirm that some athletes with impairment are disadvantaged under the current rules of VI judo.
