The aim of this study was to validate a new test of change of direction (COD) for fencer athletes and to establish its relationship with selected measures of physical fitness. Thirty-nine fencer athletes participated to this study (age: 20.8 ± 3.0 years). They performed the new specific fencing COD test (SFCODT) on two separate occasions to establish its reliability. In addition, assessment of COD, jumping ability (i.e., squat jump, countermovement jump, five jump test), sprint time (e.g., 5-m, 10-m and 20-m), isokinetic concentric and eccentric quadriceps, and hamstring force tests were assessed. To establish SFCODT's construct validity, two subgroups were identified based on their international and national fencing results: High- vs. low-ranked fencer athletes. Reliability, validity, and sensitivity of the SFCODT were established from the intraclass correlation coefficient (ICC), typical error of measurement (TEM), smallest worthwhile change (SWC), and receiving operator characteristic (ROC) analysis. The ICC of SFCODT was excellent at >0.95, and the TEM was < 5%. Based on the usefulness analysis, the ability to detect small performance changes can be rated as in fencer athletes (SWC > TEM). SFCODT was very largely associated with the COD test and moderate to very large associated with jumping ability, sprint time, and isokinetic strength. High-ranked fencer athletes were better than low-ranked fencer athletes on SFCODT ( < 0.01). The area under the ROC curve was 0.76. In conclusion, the SFCODT is a highly reliable, valid, and sensitive test. Therefore, the SFCODT could be used by practitioners to evaluate specific CODS performance in fencer athletes.
本研究旨在验证一种新的击剑运动员变向能力测试（COD），并建立其与部分体能测试的关系。39 名击剑运动员参与了这项研究（年龄：20.8±3.0 岁）。他们在两次独立的测试中完成了新的特定击剑 COD 测试（SFCODT），以建立其可靠性。此外，还评估了 COD、跳跃能力（即深蹲跳、反向跳、五次跳跃测试）、冲刺时间（如 5m、10m 和 20m）、等速向心和离心股四头肌以及腘绳肌力量测试。为了建立 SFCODT 的结构有效性，根据他们的国际和国家击剑成绩将运动员分为两组：高排名和低排名击剑运动员。SFCODT 的可靠性、有效性和敏感性通过组内相关系数（ICC）、测量典型误差（TEM）、最小有意义变化量（SWC）和接收者操作特征（ROC）分析来确定。SFCODT 的 ICC 大于 0.95，TEM 小于 5%。基于有用性分析，检测小的运动表现变化的能力可被评为（SWC>TEM）。SFCODT 与 COD 测试非常相关，与跳跃能力、冲刺时间和等速力量中度至高度相关。高排名击剑运动员在 SFCODT 上优于低排名击剑运动员（ < 0.01）。ROC 曲线下面积为 0.76。总之，SFCODT 是一种高度可靠、有效和敏感的测试。因此，从业者可以使用 SFCODT 评估击剑运动员的特定 COD 表现。
