To establish normative baseline values on the King-Devick (KD) Test for contact wheelchair sport participants. The secondary purpose was to examine the effect of physical exertion on test score.
Quasiexperimental.
Competitive disability sport venues before practices or games.
One-hundred 43 wheelchair rugby or wheelchair basketball (WBB) players completed the study. Participants were predominantly men (87.5%) and played WBB (84%).
30-m wheelchair sprint test to fatigue.
King-Devick Baseline Score.
Mean KD baseline score was 59.16 ± 15.56 seconds with significant differences ( P < 0.05) identified by sport and impairment type, but not sex. Athletes with spina bifida and cerebral palsy had significantly higher mean baseline KD times than athletes with spinal cord injury. KD scores improved by 3.5% in athletes who reported "light" to "somewhat hard" exertion (RPE = 13). In a subset of athletes who performed sprints until an RPE of 18 was reached, 8 of 12 players (66.7%) demonstrated an improvement in KD score; however, large increases by a few participants caused the noticeable change.
Normative values for wheelchair contact sport athletes are meaningfully slower than able-bodied sports participants. KD score improved with exertion with the greater improvement after moderate-intensity compared with vigorous-intensity exercise. These findings can be applied clinically to monitor athlete safety.
为接触轮椅运动参与者建立 King-Devick（KD）测试的规范基准值。次要目的是研究体力消耗对测试分数的影响。
类实验。
在练习或比赛前的竞技残疾运动场馆。
100 名 43 名轮椅橄榄球或轮椅篮球（WBB）运动员完成了这项研究。参与者主要是男性（87.5%），且多为 WBB（84%）运动员。
30 米轮椅冲刺测试以达到疲劳。
King-Devick 基础得分。
平均 KD 基础得分为 59.16±15.56 秒，不同运动类型和损伤类型的得分存在显著差异（P<0.05），但与性别无关。脊柱裂和脑瘫运动员的平均 KD 基础得分明显高于脊髓损伤运动员。报告“轻度”到“有些吃力”（RPE=13）的运动员 KD 得分提高了 3.5%。在一组进行冲刺直至 RPE 达到 18 的运动员中，12 名运动员中有 8 名（66.7%）KD 得分有所提高；然而，少数参与者的大幅提高导致了明显的变化。
有身体接触的轮椅运动运动员的正常分数明显慢于健全运动员。随着运动强度的增加，KD 得分有所提高，中等强度运动后的提高大于高强度运动。这些发现可以应用于临床监测运动员的安全。
