The KOJI AWARENESS (KA) test is a practical self-evaluation tool that assesses body movements and may help develop individual conditioning plans to improve movement function. However, the association between preseason KA scores and in-season injury occurrence remains unexplored.
To investigate whether the KA self-screening test score can predict running-related injuries in elite long-distance runners.
Cohort study; Level of evidence, 2.
A total of 47 elite college male long-distance runners (age, 18-22 years) were enrolled in this study in June 2022. The participants underwent the KA self-screening test to assess preseason upper limb, core, and lower limb function. Running-related injuries with a training time loss of >3 weeks were tracked for 6 months during the season. The participants were divided into injury and noninjury groups, and between-group comparisons and receiver operating characteristic (ROC) curve analysis were used to determine the association between the KA scores and the injury incidence. Chi-square tests and risk ratios were calculated based on the cutoff value- and injury-based grouping.
Among the runners, 10 (21.3%) sustained an injury. There were no significant differences in the demographic characteristics between the injury and noninjury groups. The injury group had significantly lower KA scores than the noninjury group (median, 44.5 [interquartile range, 43-46.8] vs median, 48 [interquartile range, 46-50], respectively; = .009). The ROC curve analysis determined a cutoff value of 46.5 points (sensitivity, 73%; specificity, 63.6%), indicating that the KA scores exhibited a relatively high predictive value for running-related injuries (area under the ROC curve, 0.764 [95% CI, 0.600-0.930]). The risk ratio for group division based on the cutoff value was 2.590 (95% CI, 1.329-5.047).
These findings demonstrated that the KA test is an effective self-screening tool for predicting the risk of running-related injuries in elite male long-distance runners.
KOJI 意识（KA）测试是一种实用的自我评估工具，可评估身体运动情况，并可能有助于制定个性化的训练计划以改善运动功能。然而，季前 KA 评分与赛季中受伤发生率之间的关联尚未得到探索。
探讨 KA 自我筛查测试分数能否预测精英长跑运动员与跑步相关的损伤。
队列研究；证据等级，2 级。
2022 年 6 月，共有 47 名精英大学男性长跑运动员（年龄 18 - 22 岁）参与本研究。参与者接受 KA 自我筛查测试，以评估季前上肢、核心和下肢功能。在赛季期间对训练时间损失超过 3 周的与跑步相关的损伤进行了 6 个月的跟踪。将参与者分为受伤组和未受伤组，并采用组间比较和受试者操作特征（ROC）曲线分析来确定 KA 评分与损伤发生率之间的关联。基于临界值和损伤情况分组计算卡方检验和风险比。
在这些跑步运动员中，10 人（21.3%）受伤。受伤组和未受伤组在人口统计学特征上无显著差异。受伤组的 KA 评分显著低于未受伤组（中位数分别为 44.5[四分位间距，43 - 46.8]和中位数 48[四分位间距，- 46 - 50]；P = 0.009）。ROC 曲线分析确定临界值为 46.5 分（敏感性，73%；特异性，63.6%），表明 KA 评分对与跑步相关的损伤具有相对较高的预测价值（ROC 曲线下面积，0.764[95%可信区间, 0.600 - 0.930]）。基于临界值分组的风险比为 2.590（95%可信区间，1.329 - 5.047）。
这些发现表明，KA 测试是预测精英男性长跑运动员与跑步相关损伤风险的有效自我筛查工具。
